Software Project Management

Notes  delphi method,
 identifying dependencies,
 examining historical data,
 estimating each task,
 documenting the results.
Popular estimation processes for software projects include:
 Cocomo

 Proxy Based Estimation (PROBE)
 Wideband Delphi
 The Planning Game
 Program Evaluation and Review Technique (PERT)
 Event chain methodology
When and Why is Estimation Done?
When
 The first estimate is necessary before the start of the project.

 Estimation is a process of gradual refinement.
 It does not finish until the project finishes.
Why
 Estimates are needed and relied upon early
 The functional requirements do not provide a solid background
 It is not immediately known how long it will take to develop the features
 Particularly if the desired outcomes are genuinely novel.
 Feature Creep is a killer
 It is the unpredictable yet near-certain change of the functionality as the project
progresses.
 Staff ability
 Estimators
 Programmers
 Code reuse
 Is code reused?
 Is code to be reused?

 Programming language used
