Process mapping involves the analysis and capture of the process steps required to move an asset from induction to repair, assembly, test, and sell. This step establishes the baseline from which improvements can be measured and implemented and helps in determining the areas of focus for detailed examination analysis and potential improvements. Using these process maps and the analysis results, KBSI, in conjunction with feedback from CCAD domain experts, next established optimal methods for engine disassembly and assembly-methods that focused the remainder of the project work.

KBSI's development of the Work Breakdown Structures (WBS) carried the process analysis to the step level by examining the Bill of Materials (BOM) and support equipment, tooling, part, and material requirements necessary to complete the individual process steps. The focus on individual component parts determines the source of supply (or suppliers) and the consumption and repair rates required per assembly-information used to drive the analysis of material supply sources for the process steps, and in the development of material control and kitting strategies.
A customized version of the KCHR tool was then configured according to the CCAD shop floor requirements and systems in place in the T-700 shops. This version of the KCHR tool allowed CCAD shop floor mechanics and managers to automatically track assets in the kits and the robbing of parts among kits for more immediate engine production needs.

CCAD is currently producing T-700 engines at a rate averaging 40 units per month (an increase of 167%), while the moving average for turn around time has been reduced to 167 days (a reduction of 55% from its peak). The methodologies developed through the EPAS effort and the RWASP effort for the UH-60 (Airframe Process Analysis Support - APAS) have been demonstrated as methods for predictable process improvement and the "leaning" of re-manufacturing processes in the depot environment.

In addition, EPAS is now paying dividends in three key areas: (1) Overhaul Cycle Time Reduction: 342 to 146 days and going down; (2) Improved Engine Life: 240 to 1080 hours on the wing; and (3) Increased Deliveries: 8 to 75 engine equivalents per month. The estimated payback to the Army from the EPAS project is $140M over the next ten years.
