The term “life cycle” implies two things: that a process is perpetual and that the sequence of events is obligatory or uni-directional. There is no beginning or end to a life cycle and the sequence of events cannot change. A seed cannot go directly to being a mature plant nor revert back to the blossom stage.
We started a writing project with a project plan and a requirements document that was referred to as a blueprint for the project. Then we allowed the project goals to change and morph as more was learned about stakeholder needs and production realities. The plan was updated including budgets and schedules and all that as we went along, but not the blueprint. That was left in the dust of history.
The principle behind portfolio management (of both projects and stocks) is that an organization has limited capital to invest and must therefore ensure that this limited capital is put to the most productive use. Projects are investments and must provide an organization with the highest possible return relative to alternative uses of capital. Just like stocks, an organization’s projects need to be managed ‘as a portfolio’, that is, in a coordinated way.
