2 Cost Estimation—A Systems Engineering Approach
Name | Description | Analysis methods |
---|---|---|
Analogical | Estimation by comparison with similar previously completed projects and existing systems | Case based reasoning |
Analytic | Estimation by the classification of a system’s lifecycle into evaluable constituent processes | Business process modelling Value stream mapping of similar systems |
Parametric | Estimation by the classification of a system into evaluable components, features or functions which are used to build a cost model supported by statistically derived scaling formulae | Bill of Materials (BOM) analysis Functional analysis Regression |
