Different Methodologies Used By Programming Teams

Different Methodologies Used by Programming Teams
Running Head: APPROACHES IN PROGRAMMING TEAMS Abstract This essay involves the
comparison and contrast of the different methodologies used by programming teams. Among these
methodologies are; System development life cycle (SDLC), Extreme programming and Agile
methodology. Software development methodologies are the frameworks involved to structure, plan
and control the processes used in developing an information system. The system development life
cycle (SDLC) is a conceptual model which is involved in most project management and used for
large scale projects with relatively large number of developers. A good example of SDCL
methodologies includes; waterfall model. The SDCL takes a lot of time to produce complete
products but of high quality. Agile methodology is a conceptual framework used also in project
management and it is designed for small projects with few developers. Extreme programming on the
other hand allow for communication with customers and by doing so it ensures interaction between
developers and consumers in order to change as fast as the customers' needs and desires changes.
Even though there different methodologies, agile methodologies seem to have a lot of advantages
over the Extreme programming and system development life cycle. Since it combines a number of
other methodologies to come up with a better way for developer to produce faster and change to as
customers desires changes. Introduction A group of methodologies are used to come up with project

Disadvantages Of Incremental Model
4. INCREMENTAL MODEL. This model involves continues user feedback and interactions
resulting in a product that is much closer to user expectations. The development is built up from an
initial Prototype that is continuously being developed and tested. The requirements of the
incremental model is divided into various builds where multiple development cycles take place. This
creates a "multi–waterfall" cycle and the cycles are divided up into smaller, more easily managed
modules. Each module passes through the requirements, design, implementation and testing phases.
A working version of software is produced during the first module, so you have working software
early on during the software life cycle. Each subsequent release of the module adds ... Show more

Increased reusability of components. Integration from very beginning solves a lot of integration
issues. Disadvantages of RAD MODEL. Depends on strong team and individual performances for
identifying business requirements. If the system cannot be properly modularized, building the
components necessary for RAD will be problematic. High dependency on modelling skills. When to
use RAD MODEL. RAD should be used when there is a need to create a system that can be
modularized in 2–3 months of time. It should be used if there's high availability of designers for
modelling and the budget is high enough to afford their cost along with cost of automated code
generating tools. 6. AGILE MODEL. Agile Development Model is also a type of incremental model
with focus on process adaptability and customer satisfaction by rapid delivery of working software
product. Agile methods break the product into small incremental releases with each release building
on previous functionality. Each release is thoroughly tested to ensure software quality is maintained.
It is used for time critical applications. Extreme Programming (XP) is currently one of the most well
know agile development life cycle

Empirical Differences Between Agile And Devops
Empirical differences between Agile and DevOps
With the increased development of software applications, increased the demand for principles in–
order to maintain quality, flexibility, cost control and maintenance. There are several models of
software development, that describes the approaches to a variety of tasks or activities that takes
place during the development process. In most of the traditional IT process, the collaboration
between the developer teams and the operational teams is minimal and sometimes there would be no
communication, which resulted in various issues like 'system works in test and doesn't work in
production environment'. To overcome this issue, various modern methodologies are developed. In

An agile project is developed in iterations, which is reviewed and critiqued by a project team.
Usually, these project teams includes representatives from the client business and the employees of
the organization. Each iteration has a time period defined with a set of goals.
Based on the properties of iteration some organizations term iteration as sprint, all sprints are
iterations but not otherwise. Sprint is a time–boxed i.e., it is finished on the planned date and not

properties can be varied, but likely you'll want to try to find an amount of time that "works well".
Agile software development supports various concrete practices that covers the areas like
requirements, process, design, coding, modeling, testing, project management and quality. These
models promote continuous integration, automatic unit testing, code refactoring and domaindriven
design are often used to improve quality and enhance project agility. Agile is not a solution for all of
the software development challenges, a good project team should always remember that
requirements would change as they design and develop. The team should be clever enough to adopt
the changes with minimum disruption irrespective of which methodology is followed. The project
teams are governed by project management with a set of responsibilities, the below table

Agile Methodologies For Software Development
Agile Methodologies for Software Development
Introduction:
In agile development model, the development of software is in incremental, rapid cycles. It is
building new features on previous functionality with each small incremental release. The software
quality is maintained by rigorously testing each release. It is useful for time critical applications. The
most well–known current agile development life cycle model is Extreme Programming (XP).
Why Agile model:
The freedom that agile gives when new changes are needed to be implemented is very important.
New changes can be implemented at very little cost because of the incremental releases. Even late
changes in requirements are welcomed
Unlike the waterfall model in agile model very limited planning is required to get started with the
project. Agile assumes that the end users' needs are ever changing in a dynamic business and IT
world. Changes can be discussed and features can be newly effected or removed based on feedback.
This effectively gives the customer the finished system they want or need. Face–to–face
conversation is the best form of communication.
In order to implement a new feature the developers need to lose only the work of a few days, or
even only hours, to roll back and implement it. Close, daily cooperation between business people
and developers. Regular adaptation to changing circumstances.
There is customer satisfaction by rapid, continuous delivery of useful software.
People and interactions are

My Company With A Crm Implementation
INTRODUCTION
This case study that I am discussing is about my earlier company in India which was in the Telecom
industry. Since there was an extremely stiff competition in the telecom industry, companies in the
telecom business were adopting to new technological imperatives in order to outperform their
competitors. Hence my company also chose to implement CRM solution which will connect all
business users, stakeholders, inter–departmental executives so that all business processes are
automated and the efficiency of operations is improved. CRM signified identifying the needs of the
customers and stretching out ways and means to satisfy them. In this perspective CRM was not
merely treated as a technology, it also had implications in the strategy formulation for the
organization.
OVERVIEW
My organization partnered with a CRM implementation company to develop and implement
customizable solution for us which will help us improve upon the operational efficiency and
effectiveness . After careful study of our company's existing processes and discussions with key
stakeholders, the consulting company advised us to follow agile practices. The other software
development models and methods are listed here below : 1. Waterfall model

WATERFALL METHODOLOGY
The waterfall model of software engineering for the systems development life cycle model is the
most popular version. Often considered classic approach to life cycle of systems development ,
linear and sequential waterfall model describes the development system. Waterfall development
objectives are different for each stage of a development .Imagine a waterfall on the cliff of an alp.
Water has flowed over the edge of a steep mountain side and has started walking down , it cannot
turn back. It is same as the waterfall development. Once a phase of development is completed, there
is no turning back when the development proceeds to the next phase. ... Show more content on

The rigidity of the model is easy to manage – Each stage has a specific distribution and review
process.
In this methodology phases are processed and completed one at a time and phases do not overlap.
Waterfall methodology proceeding well for smaller projects where requirements are very well
understood.
Disadvantages of waterfall methodology
When an application is in the testing stage, it is very hard to turn back and change something, that
was not well–thought out in the concept stage.
No working software is produced until late during the life cycle.
Uncertainty and the risk, very high.
It is not a good methodology for complex and object–oriented

If a product that is required for constructing the system but for some reason it is not available or not
known, then it can be added to the system in the later stages whenever it is sourced. This makes the
system more flexible in terms of designing and modifying. This model consists of a vast utilisation
of prototypes. Multiple versions of the same system are released along the different stages of the
spiral which makes it easy to maintain and ensures a exponential growth in the quality of the
product. Since there are a lot of stages involved in the spiral model, there is a lot of documentation
to be done at each spiral of every phase. This makes it easy to understand and implement the
requirements which leads to a successful final product. Once a concept model is complete after the
first spiral, the customers get to use the software for review purposes. This happens at a very early
stage. The work of the project can be divided into small sections(units). The Units that are classified
as high risk can be dealt earlier on in the project so that the team is ensured of minimum risk in the
later stages of the project.

Advantages And Disadvantages Of Cinder Model
Disadvantages of the Spiral Model:
1. Cost elaborated in this model is usually very high.
2. This is a complex approach especially for the project for a clear SRS ( Safety Requirement
Specification )
3. The protocols must be followed correctly to effectively apply this model. Through – out the
project life cycle development, it is very hard to follow rules and protocols.
4. It is not suitable with small risk projects.
5. Conference budgetary and scheduling needs are very though with this software development
process.

From sequential, heavy weight methodologies which are more predictive in nature and lengthy in
process, today there is a shifting focus towards simple, light weight methodologies involving
prototyping which provides a part of the final output at every stage of development. Several studies
have reported software project failures due to lack of focus on requirements and the extent of
dynamism involved in business requirement definition (Gasisas, 2009).
AGILE start as a niche concept being used in tiny pockets of the software company and has since
grown to be properly established in many diverse software development contexts. Since it has
grown, it has been modified to set unique requirements of a specific context. For Agile to be well–
known in the medical device software company, guidance is needed to modify it to fit that unique
context.
Agile developed a response to quality and efficiency concerns posed by active method of software
developments. It can bring benefits which are valuable to the medical device software world,

The highest priority of the agile process is to satisfy the customer and continuous delivery of the
software based on the scheduled time. It helps in saving the time and money. Customers, developers,
tester's plays a major role in the whole project they get interact with each other time to time.
Working builds is delivered based on the client's requirements whether it may in weekly or monthly.
Interaction between team members is very important. We can respond to the change requests based
on client requirements rather than following the planned approach and can eliminate most of the
defects and crashes at the initial stage by resolving the top most reported bugs. Collecting the
requirements from client and then analyze the requirements then design the document and prototype
and then to the development of the code after that it releases to the Quality Assurance to identify the
defects and then resolve the defects or bugs by the development team and retest by the Quality
Assurance and then submit the process to the client and then to the user for collecting the feedback
and enhancement from the customer then if necessary changes are again made by the development
team which is again processed to the quality assurance team to identify bugs then the bugs should be
resolved and retest by the QA team if the client is satisfied with the process that can be released to
the market and we can eliminate most of the defects at the initial stage. Test approach Agile way:

Developing An Information System Development
A software development methodology or system development methodology in software engineering
is a framework that is used to structure, plan, and control the process of developing an information
system.
In software engineering, a software development methodology (also known as a system
development methodology, software development life cycle, software development process,
software process) is a splitting of software development work into distinct phases (or stages)
containing activities with the intent of better planning and management. It is often considered a
subset of the systems development life cycle. The methodology may include the pre–definition of
specific deliverables and artifacts that are created and completed by a project team to develop or
maintain an application.
There are following methodologies:
Agile Software Development Crystal Methods Dynamic Systems Development Model (DSDM)
Extreme Programming (XP) Feature Driven Development (FDD) Joint Application Development
(JAD) Lean Development (LD) Rapid Application Development (RAD) Rational Unified Process
(RUP) Scrum Spiral Systems Development Life Cycle (SDLC) Waterfall (a.k.a. Traditional)

Agile is the management of incremental software development across cross functional teams.
Learned from years of successes and failures, the agile philosophy centers on software development
with an importance with self–organization, motivation, in addition to daily team interaction. It
means being able to present working software instead of slides and documentation. Agile
encourages customer collaboration throughout the entire process to allow developers to respond to
change in a timely manner. The agile development process can be implemented by different
developmental processes and is comprised of several key principles. With personal experience of the

Each increment includes a planning phase where high level requirements are defined. These
requirements are bundled into delivery cycles and at the end of each delivery cycle a working
functionality is delivered to the customer. Iterative life cycles are scalable and can be used for large
or small projects. They are also useful when projects have predefined schedule constraints. Other
types of life cycles are sequential life cycles and prototyping life cycles. Sequential life cycles
include models such as the Pure Waterfall Method, differ from agile because the product is not
delivered until the end of the project. The waterfall method however, implements phases such as the
agile method but, these phases produce documentation not working deliverables to the customer.
The waterfall method works well for projects with customers that know what they want and are fully
committed to the project. Prototype life cycle models are particularly unique. A prototype life cycle
model, such as the rapid prototyping model, is commonly utilized as a visual tool than an entire
standalone process. Rapid prototyping is designed to model a piece of software and product with
limited functionality. The rapid prototyping model is usually incorporated into the waterfall method
during the concept definition phase to provide a visual aid to the customers, since no working

The Systems Development Life Cycle Essay
The systems development life cycle (SDLC), also referred to as the application development life–
cycle, is a term used in systems engineering, information systems and software engineering to
describe a process for planning, creating, testing, and deploying an information system. The systems
development life–cycle concept applies to a range of hardware and software configurations, as a
system can be composed of hardware only, software only, or a combination of both. PHASES: o 1
System investigation o 2 System analysis o 3 Design o 4 Environments o 5 Testing o 6 Training and
transition o 7 Operations and maintenance o 8 Evaluation The system development life cycle
framework provides a sequence of activities for system designers and developers to follow. It
consists of a set of steps or phases in which each phase of the SDLC uses the results of the previous
one. The SDLC adheres to important phases that are essential for developers, such as planning,
analysis, design, and implementation, and are explained in the section below. It includes evaluation
of present system, information gathering, feasibility and request approval. A number of SDLC
models have been created: waterfall, fountain, spiral build and fix, rapid prototyping, incremental,
and synchronize and stabilize. The oldest of these, and the best known, is the waterfall model: a
sequence of stages in which the output of each stage becomes the input for the next. These stages
can be characterized and divided up in

Part B (1.1) Introduction A software development process, also known as a software development
life cycle (SDLC) can be explained as a structure, imposed on the development of a software

When in use, prototype model may increases the complexity of the system will scope of the system
expanding beyond.
Doesn't work well for smaller projects.
Leads to implementing and then repairing way of building systems.
Online systems, web interfaces have a very high amount of interaction with end users, are best
suited for Prototype model.
It might take a while for a system to be built that allows ease of use and needs minimal training for
the end user.
3. Spiral Model. As a result of these weaknesses of the waterfall model, the spiral model was
developed which emphasizes iterations of the phases with each phase producing on early Prototype
representing a part of the overall system. This helps in demonstrating a proof of concept early in
development. This model is similar to the incremental model, but with more emphasis placed on risk
analysis. A software project repeatedly passes through these phases in iterations (called spirals in
this model). The baseline spiral, starting in the planning phase, requirements are gathered and risk is
assessed. Each subsequent spirals builds on the baseline spiral.
Planning Phase – The project is reviewed and a decision is made whether to continue with a further

set of best practice to control the complete software development process. The development process
of any project has specific phases which are known as project life cycle. Usually each project has
five phases which are named as: 1– Analysis 2– Coding or Development 3– Testing or Validation 4–

This will be helpful in customer satisfaction. This model delivers face–to–face conversion between
the development team and customers which surely help to minimize risk and enhance overall
product planning. The continuous attention to a good design and technical excellence makes this
model flexible. Disadvantages Only high skilled and expert programmers are required for this
model. In this model, there is lack of emphasis on all essential documentation and designing. This
model is also not suitable to handle complex projects. 6– Spiral Model The spiral model is
somewhat similar to the incremental model. This model requires four phases which are: Planning,
Risk Analysis, Engineering and Evaluation. The spiral model focuses on early identification and
reduction of project risks as well. It is mostly used for large projects. Also used when cost and risk
evaluation is so important. Advantages One great advantage of this model is there is high amount of
risk analysis required so the avoidance of risk is enhanced. This model is flexible as it allows any
changes to be implemented at several stages of the

Agile is adaptable or highly flexible meaning that is has short development cycles of the interactive
design process that gives the project flexibility to pivot when the need arises. You do not have to
deliver a full project which wastes time and resources on delivering a full project which could be
rejected by the customer. Customer has the ability and satisfaction over the development process
since Agile projects are closely coordinated with the customer so they have a strong impact over the
development project. There is immediate user feedback and interaction among the stakeholders and
emphasis on getting a shippable product into the hands of the user which reduces the risk of building
an application that nobody wants, with the constant interaction with each other and the customer you
increase the best features. With continuous quality assurance and attention to details the quality of
the product with TDD as each iteration leads to fewer bugs and a higher quality releases. Agile has a
solid foundation that leads to quicker, higher quality releases since the development is conducted in
short cycles and with the testing that will run non–stop, it allows the production of a great final

enSeisWare can be taken as an example which advocates for the sharing of certain testing and
coding work tasks by both QA and Development. Both manual testing and the creation of automated
tests are to be shared and completed by both positions. Benefits resulting from this system include
prevention of bottlenecks in certain stages of the software development cycle as well as shared
accountability between team members for the work completed. In the previous example, there might
be a differentiation between QA and Dev testing (ie. QA's might have better black box perspective
to testing) but contrasting feedback is presented. Furthermore, this system allows for team members
to experience all aspects involved in the software development cycle and allows input by everyone.
A cohesive team mentality is encouraged and obstacles inhibiting work are removed. 2.2 Adapting
Process The effectiveness of the agile approach within a company is relative to the ability in which
processes and procedures can be adjusted to better fit its needs. A key factor for adopting successful
agile is through the encouragement of a constantly changing environment where changes can
happen frequently, become accepted as the norm, and be easily integrated into the process. Process
formalities are frequently revised to meet the needs within SeisWare. As a case scenario there was a
point in time dedicated for bug fixing during the release cycle which

concurrent development and delivery within an overall planned context. It is easy to manage and
gives flexibility to developers. But instead of these many difficulties are also there. As it is not
suitable for handling complex dependencies. More risk of sustainability, maintainability and
extensibility is in it. There are strict delivery management that dictates the scope, functionality to be
delivered, and adjustments to meet the deadlines. It depends heavily on customer interaction, so if
customer is not clear, team can be driven in the wrong direction. There is very high individual
dependency, since there is minimum documentation generated. Transfer of technology to new team

Unified Process Framework:
The Unified Process fits the wide–ranging definition of a process. It is nothing but a set of activities
that a software team performs in order to renovate a set of customer requirements into a software
system. Still, the Unified Process is also a generic process framework that people can adapt by
adding and removing activities based on the specific requirements and existing resources for a
project.
3.2. Agile Framework:
Agile software development is a conceptual framework used for undertaking software engineering
projects. There are various agile software development methodologies like Crystal Methods,
Dynamic Systems Development Model (DSDM), and Scrum.
Most of the agile methods try to reduce risk by developing software in short time boxes, known as
iterations, which usually last for one to four weeks. Each iteration is like a mini software project of
its specific, and contains all the tasks required to release the mini–increment of new functionality:
planning, requirements analysis, design, coding, testing, and documentation. Whereas iteration won't
be adding required functionality to permit releasing the product, an agile software project anticipates

to be able to release new software by the end of each iteration. At the end of each iteration, the team
reassesses project

Advantages Of Agile Software Development
1. Introduction Agile software development is a conceptual framework for software engineering that
promotes development iterations throughout the life–cycle of the project. There are many agile
development methods; most minimize risk by developing software in short amounts of time.
Software developed during one unit of time is referred to as an iteration, which may last from one to
four weeks. Each iteration is an entire software project: including planning, requirements analysis,
design, coding, testing, and documentation. An iteration may not add enough functionality to
warrant releasing the product to market but the goal is to have an available release (without bugs) at
the end of each iteration. At the end of each iteration, the team re–evaluates project priorities. Agile
methods emphasize face–to–face communication over written documents. Most agile teams are

The suitability of agile methods in general can be examined from multiple perspectives. From a
product perspective, agile methods are more suitable when requirements are emergent and rapidly
changing; they are less suitable for systems that have high criticality, reliability and safety
requirements, though there is no complete consensus on this point. From an organizational
perspective, the suitability can be assessed by examining three key dimensions of an organization:
culture, people, and communication. In relation to these areas a number of key success factors have
been identified (Cohen et al.,

Security development lifecycle are the steps that software development goes through in a bid to
come up with software that is able to withstand cyber security concerns such as worms and viruses,
cyber–attacks, and loss of data. There are various steps outlined that can assist in the development of
secure software (Dahal, 2012).

Other methods include the waterfall, which is the traditional method and is almost become obsolete.
This is because it was very expensive. It tangles the whole project and the team works in unity to
accomplish the whole project. One mistake can drag the whole team behind, and it is difficult to
debug errors. Feature driven method is another method which is costly because it focuses on
providing the best of every part of the project. Process pride has a negative effect on timing and
cost. Joint application development is the inverse of the agile software development strategy. It takes
the project as a whole and work is assigned progressively without a work breakdown structure. It is
good for very small software projects, but dangerous for lengthy software development projects
(Kaufman, Perlman, & Speciner, 2002).
From the above information the crystal method which is part of the wider agile technology is the
best method in software development. It allows a work breakdown structure that is similar to
Microsoft's security development life cycle. In addition, it allows for changes within the program
since the iterations are assigned to smaller teams and are assessed for compatibility after
submission. It is possible to identify any faults in the network security software and make changes
before the developers go too far (Kaufman, Perlman, & Speciner, 2002).

The Planning Of Software Development Project
ABSTRACT In the planning of software development project, a major challenge faced by project
managers is to predict the re–work effort. (re–work effort is the effort require to fix the software
defects identified during system testing). Project manager objective is to deliver the software that
not only meets the time and cost requirements but also the quality requirements given by the client.
To ensure the quality of the software, many testing cycle will be conducted before it is finally
delivered to the client for acceptance. Each testing cycle is a costly affair as it involves running all
possible test scenarios in all possible environments, followed by defect fixing and re–verification of
defects. On average, there are 2–3 testing cycle conducted but this depends on number of defects
identified during testing. Number of defects will depend on the team expertise and whether they
earlier worked on similar projects and technologies. Hence, it becomes critical to predict the number
of defects identified during testing and it is a very challenging task as it requires a good predicting
model to predict the re–work effort. In this paper, we describe the relationship among software size,
no of software defects, productivity and efforts for web–based development projects. This
relationship is established by using the multiple linear regression technique on the benchmarking
data published by International Software Benchmarking Standard Group. Results suggest that web
based projects

Agile And Agile Software Development
Agile Agile software development refers to a group of software development methodologies e.g.
Dynamics System Development Model, Crystal Methods and Extreme programming (XP
methodology). Agile methods attempt to minimise the risk in software in short time boxes called
iterations. Every iteration includes all the tasks necessary to release the mini increment of new
functionality: planning, requirements analysis, design coding, testing and documentation. At the end
of every iteration the priorities will be evaluated. Agile methods emphasise real time
communication, preferably face to face instead of written documents. Agile methods also emphasise
working software as the primary measure of progress. Agile methods produce very little
documentation compared to other methods. Most Agile teams are located in a bullpen and include
all the people necessary to finish the software. (1) (3) Crystal Methodology Crystal Methodology is
one of the most lightweight and adaptable approaches to software development which focuses on
people, interaction, community, skills and talents and communications. Crystal is actually made up
of a family of agile methodologies such as Crystal Clear, Crystal Yellow, Crystal Orange and others.
This refers to the underlining core which represents values and principals. The principal is that each
team has a different set of talents and skills and each team should use a process uniquely tailored to
it. (1) Dynamic Systems Development Model

The 7 Steps Of Software Development Essay
Tata Consultancy Services (TCS) is an Indian multinational information technology (IT) service,
consulting and business solutions company. TCS provide a wide range of information technology–
related products and services including application development, business process outsourcing,
consulting, enterprise software, hardware sizing, payment processing, software management and
technology education services.
TCS uses Software Development Life Cycle [SDLC] process consisting of a series of planned
activities to develop or alter the software products. These processes are normally oriented toward
either sequential software development processes, such as the Waterfall model, or Agile software
development processes, such as the Scrum model.
The 7 Steps of Software Development are:
1. Preliminary Investigation or Analysis – This is the task of extracting the requirements from users
and gauging the feasibility of the project. Project sponsors usually know what they want but often
have incomplete, ambiguous or contradictory requirements. It is the job of software developers and
project managers to steer them in the right direction and to clarify the requirements. Upper
management, both in IT and the sponsoring department, should determine if the project has business
value to the organization and if there are sufficient resources to complete the project as requested.
2. Specification and Requirement Analysis – This step can vary a lot depending on the formality,
size, and scope of the

Software Development : Developing A New Program
In the world of software development, the term agile typically refers to any approach to project
management that strives to unite teams around the principles of collaboration, flexibility, simplicity,
transparency, and responsiveness to feedback throughout the entire process of developing a new
program or product. And agile testing generally means the practice of testing software for bugs or
performance issues within the context of an agile workflow.
Agile testing is a software testing practice that follows the principles of agile software development.
It follows the rules of the agile manifesto, treating software development as the customer of testing
and thus involves testing from the customer perspective as early as possible, testing early and often
as code becomes available and stable enough from module/unit level testing. Since working
increments of the software is released very often in agile software development there is also a need
to test often. This is often done by using automated acceptance testing. Also since manual testing
alone in agile development would likely result in either buggy software or slipping schedules
because it would most often not be possible to test the whole software manually before every
release.
Agile testing involves all members of a cross–functional agile team, with special expertise
contributed by testers. This is done to ensure the delivery of the business value desired by the
customer at frequent intervals by working at a sustainable

Abstract–There are various SDLC models widely accepted and employed for developing software.
SDLC models give a theoretical guide line regarding development of the software. Employing
proper SDLC allows the managers to regulate whole development strategy of the software. Each
SDLC has its advantages and disadvantages making it suitable for use under specific condition and
constraints for specified type of software only. We need to understand which SDLC would generate
most successful result when employed for software development. For this we need some method to

Software Houses Use Agile Development
Most of software houses use agile development methodologies such as XP and scrum to enhance its
product quality, increase communication between teams, release products in short time and to
participate its clients in software development life cycle. There are many problems usually occur,
first problem the time spent between development of the software and to make it operational.
Second problem is the difference between environments. There are two different environments;
development environment is the first environment which is used to develop, build and deploy the
software in development life cycle. This environment has no constrains. On the other hand,
operation environment, which is usually called production environment. In operation ... Show more
These enhancements aim to decrease time of software life cycle. Additionally, it aims to increase
productivity and quality of software. Moreover, some researches introduce the idea of mixing two or
three approaches together to enhance software lifecycle.
Recently, a new approach called "DevOps" appeared in software engineering field. DevOps derived
from Development and Operations. The main objective of DevOps is to resolve conflicts between
teams and reduce time between software development and software delivery to customer. But there
are differences between development environment and operation environment. Development
environments are business driven, responsive to change and constantly updated. On the other hand,
operation environment is procedure driven, controlled environment and stable. [1]
DevOps challenge is to map between development and operation. The main challenge her is both of
development and operation have a different environment. Whereas Development environment is
changing environment, production environment is stable. The major challenge here is to deliver
changes in stable environment without any kind of interruption. The key solution for this challenge
is continuous integration [2].
DevOps is considered as an extension to agile methodologies [2]. Another view is that it is a
separated method [1]. Table 1 shows the evolution of development methodologies and IT

additional hours to do research to put the course in place. This is the stage where the content is not
only written or developed but the content is also organized (University of Idaho, n.d.). It is
imperative that this stage is done correctly so as to deliver information to students that will help

When deciding on a safety meeting, managers need to decide what the company needs to address
with their employees and then the Safety Officer at Cornella will create a Power Point or show
pictures of the violations (Work Place Safety Experts, 2010).
Inputting Technology Cornella Brothers is a medium sized family business. The organization is
nowhere near being large enough to have an IT Department. Due to this managers and the safety
officer hold many hats in the organization. The Safety Officer or one of the managers will input the
information into technology. It would be nice to have an IT Department or even an accountant to do
the billing but these tasks falls upon the managers.
Beta Testing There really is no beta test involved in the safety classes. Employees are expected to
follow the guidelines put in place at these classes. Managers will ensure that the employees are
following government regulations and the company's regulations. A part of their employment
obligation is following the safety rules and managers do enforce this. During the classes there is a
discussion period in which employees have the opportunity to voice their concerns or ask questions;
in this way managers can be sure the employees understand what is expected of them and can
respond immediately or discuss pertinent matter further.
Conclusion
At Cornella Brothers, the subject matter experts are the ones who author the

Extreme Programming : A Successful Customer Satisfactions...
Introduction
Extreme Programming is one of the popular agile processes (Wells) and is about social changes
(Beck and Andres). XP has been proven as one of the successful customer satisfactions since it
delivers potential software that can be used, as the customer needs it. It continues to empower
developers as it focus on developing excellent programing techniques and communication (Beck
and Andres). Extreme programming includes collaborative teams in order to accomplish and solve
problems as efficient as possible (Wells). Extreme programming hav five essential ways to improve
software projects such: communication skills, simplicity, require feedback, respect and courage
(Wells). An XP programmer requires maintaining communication with customers and colleague, and
sustaining their design simple and clean (Wells). Programmers are to get feedback by testing the
software, and delivering end system product to the customers as early s possible (Wells). Lastly,
programmers respect their colleagues as they, together, courageously respond to the changing and
evolving technology (Wells).
In addition, XP has its own twelve simple rules these rules are: planning, building blocks or small
releases, standardized naming schemes, collective ownership, coding standard, simple design,
refactoring, testing, pair programming continuous integration, 40–hour workweek and on–site
customer (Hutagalung). Although XP is an improved process, more efficient and predictable, it has
its own weakness

What The Software Design Life Cycle?
Assignment 2 P5
To achieve P5, learners are expected to:
a) Describe and explain what the Software Design Life Cycle is
The SDLC Software design life cycle is used for the design and development stage of a software
system. It's the structure for design and development the life cycle has multiple stages, there are 9 in
total. Requirements, Specification, Design, implementation, testing and debugging, deployment,
maintenance and post mortem. All of these stages are part of the software design life cycle. The
reason they use the SDLC is to see if the software there producing is up to standards meets their
desire of design.
b) Describe and explain the nine necessary stages of the life cycle:
Requirements

Specification
This is the second step of SDLC it's called Specification in this stage both developers and clients are
deciding on who their going to realise the software for the age audience. The hardware and software
requirements to make sure its compatible with the users for example if their making it for Mac or
Windows they need to make it compatible for that OS. Other specification the input and output of
the data and what's needed to show the user. So the main specification to cover is the function of the
software and hardware but also the security system logging in and out.
Design
Design is the third stage of the SDLC. This is thinking more into the visual side of the process by
planning the code and design for the software, by designing the GUI/user interface. Creating
diagrams for the visual look doing a flow diagram and the step of that process. Once the developers
have decided on the design of the software such as the interface and creating the diagrams they
would then move on to the fourth stage of SDLC
Implementation
This is the fourth stage of SDLC, the implementation is putting the physical code design that was
created from the design stage and making it. This part of the process can slow the project down even
though you have planned it you can still run into problems and errors this could delay the process.
The developers that have built the software they then need to move

Programming (XP): Extreme Programming technique is very helpful when there is constantly
changing demands or requirements from the customers or when they are not sure about the
functionality of the system. It advocates frequent "releases" of the product in short development
cycles, which inherently improves the productivity of the system and also introduces a checkpoint
where any customer requirements can be easily implemented. The XP develops software keeping
customer in the target. Figure 4:QA Development cycle of Extreme Programming(XP) Business
requirements are gathered in terms of stories. All those stories are stored in a place called the
parking lot. In this type of methodology, releases are based on the shorter cycles called Iterations
with span of 14 days time period. Each iteration includes phases like coding, unit testing and system
testing where at each phase some minor or major functionality will be built in the application.
Phases of eXtreme programming: There are 6 phases available in Agile XP method, and those are
