Abstract

Process Capability Index (Cpk) has been used at some manufacturing companies to enable them to exactly monitor and getting feedback from process capability of their production department. This report includes the effective implementation of Process Capability Index (Cpk) in minimizing reject rate for batch production. Hicom Engineering Sdn Bhd, which located in Shah Alam, Selangor was selected for this project. This project also covered the present application of process Statistical Process Control (SPC) that applied at Hicom Engineering Sdn Bhd. SPC is used for datagathering and to investigate problem the trends over time for the automotive part in the production line of this company. This project is also aimed to design and recommend new software for calculating Cpk called Operator Friendly Software (OFS). This software is designed for evaluation of one aspect of product quality which is process capability that can be used easily by production and quality control operators in order to minimize the reject rate in the line production. The developed software was not tested to check its effectiveness due to time constraint. However, the initial feedback obtained from the staff through the survey showed it is potentially effective because the time taken to set the result is very shorter compared to present practice.
