Quality
How do we validate what is built?
What does success look like?

Done
Team defines done (Definition of Done)
Should be a specific list, e.g.
Code complete
Tests pass
Everything checked-in
Acceptance criteria from Product owner met
Potentially Shippable
Fit for Purpose

Bug Fixing Goals
Quickly fix and move on?
Ignore?
Or improve software.

Fixing a Bug
