2. 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 ...

3. Spatial analysis - Wikipedia

   en.wikipedia.org/wiki/Spatial_analysis

   Spatial regression methods capture spatial dependency in regression analysis, avoiding statistical problems such as unstable parameters and unreliable significance tests, as well as providing information on spatial relationships among the variables involved. Depending on the specific technique, spatial dependency can enter the regression model ...

4. Program evaluation and review technique - Wikipedia

   en.wikipedia.org/wiki/Program_Evaluation_and...

   The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project. PERT was originally developed by Charles E. Clark for the United States Navy in 1958; it is commonly used in conjunction with the Critical Path Method ...

5. Boundary problem (spatial analysis) - Wikipedia

   en.wikipedia.org/wiki/Boundary_problem_(spatial...

   In spatial analysis, four major problems interfere with an accurate estimation of the statistical parameter: the boundary problem, scale problem, pattern problem (or spatial autocorrelation), and modifiable areal unit problem. [1] The boundary problem occurs because of the loss of neighbours in analyses that depend on the values of the neighbours.

6. 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 ...

7. Cost estimation models - Wikipedia

   en.wikipedia.org/wiki/Cost_estimation_models

   Cost estimation models are mathematical algorithms or parametric equations used to estimate the costs of a product or project. The results of the models are typically necessary to obtain approval to proceed, and are factored into business plans, budgets, and other financial planning and tracking mechanisms.

8. SEER-SEM - Wikipedia

   en.wikipedia.org/wiki/SEER-SEM

   D is staffing complexity - a rating of the project's inherent difficulty in terms of the rate at which staff are added to a project. E is the entropy - In days gone by entropy was fixed at 1.2. Next it evolved to 1.04 to 1.2 depending on project attributes with smaller IT oriented projects tending toward the lower.

9. 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.
