Involved from start to finish up until the hand-off of a successful test to its respective product owner. A SME in the Optimizely tool, owner of test setup, deployment, and analysis. • Product Partner: Talks to and brings in the right people for different steps of the process. Offers product’s perspective in terms of gatekeeping duties on test ideas. Well connected to different product owners and acts as the liaison towards the product team. • QA Partner: Helps ensure that there are no bugs in the test setup, from a usability standpoint. • Technology Partner: Offers consultation on feasibility for tests, assists in setup of advanced tests. • Design Partner: Helps the team germinate ideas, as well as give the team visuals to work off of in a test.

- 26. THINGS WE WATCHOUT FOR • Engineering overheads – every time a new flow needs to be introduced or any major addition to the experience, new development is required. It has to go through Standard engineering prioritization route unless a SWAT team is dedicated to it. • Tricky QA situations – QA team should be trained to handle A/B Testing scenarios and use cases; Integration with automated QA tools. Security and FE load failure considerations apart from standard checks. • Operational excellence requirements – Testing of the Tests in Sandbox, Staging and Live Site Testing areas. End to End Dry runs mandatory being launching the tests. • Analytical nuances – Experiment Design supreme need! External factors can easily invalidate A/B Testing. Sample fragmentation with increasing #tests and complexity; Need for Universal Control; Impact should be checked for significance over time. • Data needs – Reliable instrumentation, Testing Tool JavaScript put in right place, with minimal overhead performance impact, integration with Web Analytics tool, Data feed with ability to tie with other data sources (for deep dives). • Branding Guidelines – Don’t overwhelm and confuse users in quest for multiple and complex tests; Standardize but customize experience across various channels and platforms; Soft launches should be as much avoided as possible. • Proactive internal communication, specifically to client facing teams. • Strategic Decisions – Some changes have to go in irrespective of A/B Testing findings, the question would be how to make it happen right? This is gradual ramp, progressive learning and iterative improvements – a collection of A/B Tests and not one off big one. …A/B Testing can never be a failure, by definition it is a learning on whether the change was well received by the user or not that informs the next steps

Were you successful in up-leveling the conversation in your organization? How did you crack the Resourcing & Funding problem? What are the things that worked best for you in your journey? How did you protect Testing resources from being used up for CMS or Bug Fixes? How did you manage the nuance between Learning and Business Objectives? How did you convince the organization to use Testing as driver of accountability but also not get dragged into for political issues? Intended for Knowledge Sharing only
