[1][2] PRICE related the basic costs of engineering and production to parameters that included a specification profile of units to be built, amount of work to be performed, the allowed schedule and resources available.
It relied on the use of parametric relationships obtained through curve-fitting procedures that had been performed on a historical repository of significant cost data.
In 2003 PRICE released TruePlanning, a proprietary parametric model that estimates the scope, cost, effort, and schedule for software projects.
Today, TruePlanning is used to estimate the costs, schedule, effort, and benefits for: Customers include DOD Program Office, BAE Systems, Boeing NA, Eurocopter, Gulfstream Aerospace,
US Naval Air Systems Command (NAVAIR), Penn State Applied Research Laboratories (ARL), Sikorsky Aircraft and United Technologies Corporation.
