Proxy-based Estimating
Proxy-Based Estimating (PROBE) is an estimating process used in the Personal Software Process (PSP) to estimate size and effort. Proxy Based Estimating (PROBE), is the estimation method introduced by Watts Humphrey (of the Software Engineering Institute at Carnegie Mellon University) as part of the Personal Software Process (a discipline that helps individual software engineers monitor, test, and improve their own work). PROBE is based on the idea that if an engineer is building a component similar to one they built previously, then it will take about the same effort as it did in the past. In the PROBE method, individual engineers use a database to keep track of the size and effort of all of the work that they do, developing a history of the effort they have put into their past projects, broken into individual components. Each component in the database is assigned a type (“calculation,” “data,” “logic,” etc.) and a size (from “very small” to “very large”). Wh ...

Estimation In Software Engineering
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 Point ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
