ACCOUNTABILITY
Ask Yourself:
 Do I know who my customers are?
 Am I looking for ways to help improve and
make things better for my customer?
 Do I “own” understanding how my work
impacts the team, the sustainability of the
product, and ability to deliver to the
customer?
 Am I thinking beyond my functional area of
responsibility?
