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?
