== Methods ==

Methods for estimatingestimation various aspects ofin software engineering include these principles:

*[[Analysis effort method]]

*[[Estimation theory|Parametric Estimating]]

Line 11:

*[[Proxy-based estimating]] (PROBE) (from the [[Personal Software Process]])

*[[Program Evaluation and Review Technique]] (PERT)

*[[Putnam_modelPutnam model]], also known as SLIM

*[[PRICE Systems]] Founders of Commercial Parametric models that estimates the scope, cost, effort and schedule for software projects.

*[[SEER-SEM]] Parametric Estimation of Effort, Schedule, Cost, Risk. Minimum time and staffing concepts based on [[Brooks's law]]

Line 18:

*[[Wideband Delphi]]

Most cost software development estimation techniques involve estimating or measuring software size first and then applying some knowledge of historical of cost per unit of size. Software size is typically sized in [[Source lines of code|SLOC]], [[Function Point]] or [[Burn down chart|Agile story points]].
