What is the primary advantage of adhering to a life cycle model?

Confining attention to a few models

Developing software in a chaotic and undisciplined manner

Creating project failure

Helping the team understand when to do what (correct)

When is a phase considered complete in a life cycle model?

Even if some exit criteria are not met

When team members agree it is complete

When all entry criteria are satisfied

Only when all exit criteria are satisfied (correct)

What must happen before a phase can start in a life cycle model?

Phase-entry criteria are satisfied (correct)

All exit criteria are satisfied

Team members review the phase
