Standard Classification for Cost Estimate Classification System
1.1 This classification provides a generic classification system for cost estimates and provides guidelines for applying the classification to cost estimates.
1.2 This classification maps the phases and stages of cost estimating to a generic maturity and quality matrix, keyed to a degre of project definition, that can be applied across a wide variety of industries.
1.3 The Cost Estimate Classification System has been developed in a way that:
1.3.1 provides a common understanding of the concepts involved with classifying cost estimates;
1.3.2 defines and correlates the major characteristics used in classifying cost estimates, and;
1.3.3 uses the degree of project definition as the primary characteristic used to categorize estimate classes.
