In project management (e.g., for engineering), accurate estimates are the basis of sound project planning. Many processes have been developed to aid engineers in making accurate estimates, such as
- Analogy based estimation
- Compartmentalization (i.e., breakdown of tasks)
- Cost estimate
- Delphi method
- Documenting estimation results
- Educated assumptions
- Estimating each task
- Examining historical data
- Identifying dependencies
- Parametric estimating
- Risk assessment
- Structured planning
Popular estimation processes for software projects include:
- Cocomo
- Cosysmo
- Event chain methodology
- Function points
- Planning poker
- Program Evaluation and Review Technique (PERT)
- Proxy-based estimating (PROBE) (from the Personal Software Process)
- The Planning Game (from Extreme Programming)
- Weighted Micro Function Points (WMFP)
- Wideband Delphi
