Window Manufacturing Company (WMC) in Puerto Rico is a prestigious and visionary brand in the manufacturing industry of doors, windows, and architectural solutions, which over 55 years of experience. Glass and aluminum are two of the materials used in their production operations to deliver high quality doors and windows. In the critical areas of the glass-cutting process, there are no existing metrics or standardizations evaluate the state of operations. This research aims to improve the glass cut process output from 4,500 to 6,500 square feet daily. To achieve this objective, the entire process
must be analyzed and observed from beginning to end to identify the root causes of the deficiencies in the maximization of capacity and production of glass cutting. Since the glass cutting line is the most demanded and has much variability in products, styles, sizes, and measurements, we can cut 6,500 square feet daily with 3.4 hours of overtime, which means an annual loss near $60,000. We use different empirical methods to analyze data, such as Lean Six Sigma, DMAIC methodology, and production optimization. By implementing several design alternatives, the objectives set for the project were reached and exceeded.
