which 2 things a SM do if the dev team doesn't have the engineering tools
& infrastructure to completely finish any PBI?
1. has the dev team define 'done'& do the same work for all PBI it selects
2. declares the dev team is not ready for scrum
3. has the dev team improve its skills, tools & infrastructure over time
& adjust the definition of 'done' accordingly
4. asks the dev team to do their best it can on each PBI
5. asks the dev team to spend as many sprints as necessary to prepare the
engineering tools & infrastructure so any PBI it selects is potentially
shippable at sprint end
