PRISM Project Estimator is multi-project, multi-user, concurrent access database system for developing and maintaining project cost estimates. It is designed to support a structured "building-block" methodology for developing project cost estimates. This approach maximizes consistency of estimate information while minimizing repetitive data entry. The system uses a Work Breakdown Structure (WBS) coding system as the key to organizing estimate data. This structure is identical to the structure found in PRISM Project Manager and allows a seamless interface between the detailed cost estimate developed with PRISM Project Estimator and the budget, actual, and forecast data contained in PRISM Project Manager.
The "Building Block" Structure of PRISM Project Estimator has many advantages:
Estimates can be developed rapidly, since the basic units
(the building blocks) are already defined and in place. With predefined work
element cost models and assemblies the estimator simply applies a quantity
takeoff to the cost model or assembly code and the complete detailed estimate is
calculated.
