7. The Process
Model:
Adaptability
t the framework activities will always be
applied on every project ... BUT
t the tasks (and degree of rigor) for each
activity will vary based on:
¶ the type of project (an “entry point” to the model)
¶ characteristics of the project
¶ common sense judgment; concurrence of the
project team

8. The Primary Goal:
High Quality
Remember:
High quality = project timeliness
Why?
Less rework!

13. Still Other Process
Models
t Component assembly model—the process to apply
when reuse is a development objective
t Concurrent process model—recognizes that different
part of the project will be at different places in the
process
t Formal methods—the process to apply when a
mathematical specification is to be developed
t Cleanroom software engineering—emphasizes error
detection before testing
