Predictive LifeCycles

Predictivelifecycles(alsoknownasfullyplan-driven)areonesinwhichtheprojectscope,andthe
timeandcostrequiredtodeliverthatscope,aredetermined asearlyintheprojectlife cycleas
practicallypossible.Theseprojectsproceedthroughaseriesofsequentialor overlappingphases,
with each phase generally focusing on asubset of project activities and project management
processes.Theworkperformedineachphaseisusuallydifferentinnaturefromthatinthepreceding
andsubsequentphases;therefore,themakeupandskillsrequiredoftheprojectteam mayvaryfrom

Iterative and Incremental LifeCycles

Iterative and incremental life cycles are ones in which project phases (also called iterations)
intentionallyrepeatoneormoreprojectactivitiesastheprojectteam’sunderstandingoftheproduct
increases.Iterations developtheproduct throughaseriesofrepeatedcycles,while increments
successivelyaddtothefunctionalityoftheproduct.Theselifecyclesdevelop theproduct both
iterativelyandincrementally.
