SCOPE

story is high priority, small, minimize creep, no stray changes, off-task changes added to backlog


WORKS CORRECTLY

master merged into branch,
all changes tested,
edge cases covered,

Engineering

1. What tech stack do you use? Are you rolling out new technologies or sunsetting older ones? Do you have any legacy system that you need to maintain?
2. What is your maturity stage? Finding a direction, feature work, maintenance...
3. What are the next big engineering challenges you will face?
4. How are requirements delivered to the engineering teams? How are technical decisions made and communicated?
5. What level of involvement do engineers have in relation to architecture and system design? How much freedom for decision making do individual developers have? What happens if an engineer identifies areas of improvement?
6. What is the junior/senior balance of the team?
