CTY Incorporated was organized in 1974 to undertake the manufacture of the Armed Forces (AF) tactical radios with the secondary perspective of giving employment to the qualified veterans. Consequently, the AF commissioned CTY to develop radio sets and ancillaries. Currently, CTY continues the commercial sub-contract projects such as Flapper and Minola. The study focuses on the company's manufacturing process of Minola products. This is in connection with the company's search for alternatives to recover its past losses and at the same time find ways to win back the trust and confidence of the AF. This includes all departments involved with the receiving and storage of raw materials and the processing of these raw materials to obtain finished goods. Other projects are not included. There are four models assembled by CTY Inc. for Minola. These models are 2099, 2429, 2101, and 2202 which are board parts of cameras. The company is only paid for the assembly of the boards. Production has direct relationships with Production, Planning and Materials Control (PPMC), Engineering, and Quality Control / Quality Assurance (QCQA) departments. The customer specifies production volume and deadline dates for PPMC, relays consumable specifications to Engineering, and sets quality standards for QCQA. In turn, PPMC, QCQA, and Engineering coordinate with one another to achieve customer requirements and demand. Problems of the company were evaluated using Pareto Analysis. Results showed that 80% of the weaknesses identified are composed of deviations from production of three models. These are additional monthly costs for the production of models 2202, 2099, and 2101. It is found that the three models have common rejects incurred in the assembly process. These are rejects found by QC and QA. Considering all the models including 2429, the additional costs are due to the rejects from QC/QA. Consequently, rejects, whatever type it may be, is caused mainly of manual operations. These manual errors may be caused by worki
