  2. Software development effort estimation - Wikipedia

    en.wikipedia.org/wiki/Software_development...

    Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data. Combination-based estimation: The quantification step is based on a judgmental and mechanical combination of estimates from different sources. Below are examples of estimation approaches within each category.

  3. Putnam model - Wikipedia

    en.wikipedia.org/wiki/Putnam_model

    An estimated software size at project completion and organizational process productivity is used. Plotting effort as a function of time yields the Time-Effort Curve. The points along the curve represent the estimated total effort to complete the project at some time. One of the distinguishing features of the Putnam model is that total effort ...

  4. Wideband delphi - Wikipedia

    en.wikipedia.org/wiki/Wideband_delphi

    The first meeting is the kickoff meeting, during which the estimation team creates a work breakdown structure (WBS) and discusses assumptions. After the meeting, each team member creates an effort estimate for each task. The second meeting is the estimation session, in which the team revises the estimates as a group and achieves consensus.

  5. COCOMO - Wikipedia

    en.wikipedia.org/wiki/COCOMO

    The Intermediate Cocomo formula now takes the form: E = a i (KLoC) b i (EAF) where E is the effort applied in person-months, KLoC is the estimated number of thousands of delivered lines of code for the project, and EAF is the factor calculated above. The coefficient a i and the exponent b i are given in the next table.

  6. Estimation (project management) - Wikipedia

    en.wikipedia.org/.../Estimation_(project_management)

    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 ...

  7. Use case points - Wikipedia

    en.wikipedia.org/wiki/Use_Case_Points

    Now that the size of the project is known, the total effort for the project can be estimated. For the Online Shopping System example, 28 man hours per use case point will be used. Estimated Effort = UCP x Hours/UCP For the Online Shopping System, Estimated Effort = 125.06 x 28 Estimated Effort = 3501 Hours

  8. Basis of estimate - Wikipedia

    en.wikipedia.org/wiki/Basis_of_estimate

    Earned Value Management is a second tool within project management that allows for the tracking of progress throughout the life cycle of a project. BOEs, when executed properly and with the aid of certain software packages, allow for a seamless transition from project proposal to execution by transferring data from the BOE directly into ...

  9. Halstead complexity measures - Wikipedia

    en.wikipedia.org/wiki/Halstead_complexity_measures

    The effort measure translates into actual coding time using the following relation, Time required to program: = seconds; Halstead's delivered bugs (B) is an estimate for the number of errors in the implementation.
