Circuit Board Fabricators, Inc. Case Analysis – Week 3 Essay

Decent Essays

Case Summary Circuit Board Fabricators, Inc. is a small manufacturer of circuit boards located in California. (Chase, Jacobs, and Aquilano, 2004) Large computer companies such as Apple and Hewlett-Packard hire Circuit Board Fabricators to "make boards for prototypes of new products." (Chase, et al., 2004) The case study suggests that Circuit Board Fabricators has a good business plan established within the organization. CBF has implemented a largely automated process using industry standard codes to produce the four circuit boards that have been developed to be able to give quick and high quality service. There have been recent losses experienced by CBF, due to the system that is currently in place. The policy has changed and all …show more content…

It takes nearly ¾ of an hour just to load and unload the circuit boards. There is a significant amount of manual labor in this flow process in which human error must be taken into consideration. It appears that some of the stations may be run by an inefficient amount of operators. Lastly, with 6 employees on 6 machines for the final inspection, the end of the process should not take as long as it does. Case Question #4: What is the impact of losses in the process in Inspection and Final Test? The impact of the losses in the system is quite extensive. It is stated that 15% of the board are typically rejected during an early processing inspection along with an additional 5% rejected during the final testing. This results in a production order increase of 25%. Ultimately, the first
