Strategic Multi-Factor Root Cause Analysis for Lead Time Optimization in Jewellery Manufacturing

One of the strengths that company need to have been the ability to release new models faster than competitors. It will give the opportunity for the company to capture the market share. However, company need to have a quick mass producing for the new models after prototype released to the market. Slow mass producing will open the window for the competitor to imitate the prototype and give the chance for them to capture all the markets if they have quicker mass-producing time. This issue happens in jewellery companies in Indonesia, one of the companies is XYZ Company. Prototype models from XYZ company are widely imitated by competitors who have faster production time. To overcome this issue, company need to analyse the root cause of slow mass production process in the company. Based on this analysis, recommendations can be given to the company and applied to accelerate the production process so the company will not lose the market anymore. The root cause analysis was conducted by using a fishbone diagram with a case study in XYZ company. Through the analysis, it can be seen that the root cause of the slow production time is due to lack of human resources thar involved in production. Based on this finding, series of measures such as hiring additional employees and implementing the overtime hours for the employee can be applied to speed up the production time and even increase the capacity.
