4. Section 7.1.2 discusses the change-instability cycle. Draw a series of graphs where
the x -axis is time and the y -axis is the measure of stability. Each graph should rep-
resent two months of project time.
Each Monday, a major software release that introduces instability (9 bugs) is rolled
out. On Tuesday through Friday, the team has an opportunity to roll out a “bug-
fix” release, each of which fixes three bugs. Graph these scenarios:
(a) No bug-fix releases
(b) Two bug-fix releases after every major release
(c) Three bug-fix releases after every major release
(d) Four bug-fix releases after every major release
(e) No bug-fix release after odd releases, five bug-fix releases after even releases
5. What do you observe about the graphs from Exercise 4?
6. For a service you provide or have experience with, who are the stakeholders?
Which interactions did you or your team have with them?
7. What are some of the ways operations work can be organized? How does this com-
pare to how your current team is organized?
8. For a service you are involved with, give examples of work whose source is life-
cycle management, interacting with stakeholders, and process improvement and
automation.
9. For a service you are involved with, give examples of emergency issues, normal
requests, and project work.
