Project stages

From that previous diagram, let's concentrate on those stages involved in developing software.

"Stage" is equivalent to "Milestone" but is not quite the same as "Phase"

A typical "waterfall" model


Sometimes, like salmon, we must travel "up" the waterfall

Project stages

Why have stages?

Break a large problem down into smaller, more manageable problems

A tool for monitoring progress

Points at which senior management assess project viability:

Management authorisation to proceed with next block of work

Concentrates the mind

Project stages

How do you decide what stages a project should have? How many? How long?



How do you even know what tasks are needed in a project?



One approach

  1. Product breakdown structure
  2. Product flow diagram
  3. Identify key products; stage ends when those products are completed
