This is a quick work breakdown structure example.
Idea: Allocate proportions of an effort estimate to different activities of the project
Inputs: Main project activities (high level design) and earlier project data on efforts spent for activities
Outputs: Rough work breakdown with corresponding effort estimates
Advantages: Takes into account integration, configuration management and documentation costs (e.g. algorithmic models seldom take)
Disadvantages: Underestimating the difficult low-level technical problems
