Perfecting project deliverables and achieving all anticipated goals when employing the
waterfall approach is an arduous task. The iterative model for development and managing services,
however, can avoid some of these pitfalls by introducing different dynamics to project
development called iterations. This method suggests repeating important activities of the life
cycle until they are done right. Iterations should continue until project deliverables are acceptable
and qualified.
Iterations do not imply going back in time in each enhancement cycle. It means doing
things repeatedly until satisfactory results have been achieved. These perfection efforts must
be carefully formulated and reflected in a project??™s plan and timetable. Iterations can come in
different flavors: One can iterate on small groups of activities, such as service analysis, or on
larger service development and production tasks such as service integration. Either approach
should be documented and planned in advance to avoid time and budget miscalculations.
What are the most common iteration models that can be applied to service life cycles?
How can iterations be managed during the service life cycle? The answers to these questions
are associated with the scope of the service-oriented initiative. If these are large-scale development
and production activities, iterations that cover smaller portions of projects are highly
recommended.
