Cost estimation in software engineering GudangMovies21 Rebahinxxi LK21

    Cost estimation in software engineering is typically concerned with the financial spend on the effort to develop and test the software, this can also include requirements review, maintenance, training, managing and buying extra equipment, servers and software. Many methods have been developed for estimating software costs for a given project.


    Methods


    Methods for estimation in software engineering include these principles:

    Analysis effort method
    Parametric Estimating
    The Planning Game (from Extreme Programming)
    ITK method, also known as Method CETIN
    Proxy-based estimating (PROBE) (from the Personal Software Process)
    Program Evaluation and Review Technique (PERT)
    Putnam 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
    The Use Case Points method (UCP)
    Weighted Micro Function Points (WMFP)
    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 SLOC, Function Point or Agile story points.
