Core problem solving (CPS) – Kepner Tregoe Approach to Strengthen Quality Performance at PT. UTC Aerospace System Bandung (UTAS BANDUNG)

Abstract

Purpose: Aiming of this research to see effectiveness of Core Problem Solving (CPS) with Kepner Tregoe approach able to improve %SRR performance from 0.73% in 2022 to become 0.5% in the next 5 years and take the right solutions to be planned in 2023.
 Methods: Study on this case at UTAS Bandung with focus to see %SRR performance that drive by amount scrap, rework and repair part as called cost of poor quality (CoPQ) divide by total amount part sold to customer. Core Problem Solving (CPS) combine with Kepner Tregoe Method able to strengthen quality performance. Starting with problem identification following by problem analysis use pareto diagram, ishikawa diagram (fishbone diagram), five why analysis to get the correct root cause and come out with alternatives solution to prevent future fault.
 Results/findings: Based on problem analysis had been found the highest CoPQ contributor come from Prismatic cell around 61% or $154,000 of total CoPQ $254,300 at 2022. To reach 0.5% target in 2027 need to improve around $81,115 within 5 years or similar with $16,223 per year. Core problem solving (CPS) combine with Kepner Tregoe method will apply to achieve quality performance as planned.
 Limitations: This research only referring to data that available in SAP based on performance in 2022 without counting return part from reject customer and reject part caused by supplier.
 Contribution: With implement core problem solving (CPS) combine with Kepner Tregoe Approach showing the right direction and good impact for quality performance at UTAS Bandung. It gives concern to develop army of core problem solving by encourage more people learn about it. It will also be able to copy as benchmark for other site in global groups.
