Use of this classification will improve communication among all the stakeholders involved with preparing, evaluating, and using cost estimates.
The various parties that use cost estimates often misinterpret the quality and value of the information available to prepare cost estimates, the various methods employed during the estimating process, the accuracy level expected from estimates, and the level of risk associated with estimates.
This classification applies the level of project definition as the primary characteristic for determining an estimate’s classification.
Using this classification will help those involved with project estimates to avoid misinterpretation of the various classes of cost estimates and to avoid their misapplication and misrepresentation. Improving communications about estimate classifications reduces business costs and project cycle times by avoiding inappropriate business and financial decisions, actions, delays, or disputes caused by misunderstandings of cost estimates and what they are expected to represent.
This classification is intended to be generic and so provide a system for the classification of cost estimates in any industry.
Estimate classifications provide valuable additional reporting information when used as an adjunct to Practice E 1804.
