Method · AACEApply the right AACE contingency and accuracy range to your estimate — Classes 1 to 5 per RP 17R-97 / 18R-97, with definition-maturity guidance.
Method · AACEDetermine the AACE estimate class your deliverables actually support — score 18 project-definition deliverables (RP 18R-97 logic) and see the class, its accuracy range, and what separates you from the next one.
