The objectives of this project are to reduce the defects and improve the customer satisfaction, and consequently decrease the waste and improve the profitability in a metal and wood industries’ company. After collection and analysis of the data taken from assembly stage, the team found that the main problem causing the defects is coming from two machines: tongue and mortise machines, besides that worker do not have enough experience and awareness about how to work with the machine. So, the team decided to make inspection sheet on those two machines to reduce defects and improve quality and to reduce time waste and cost and making jigs to most products produced to reduce time of inspection. Also make a training program to improve efficiency of workers. Moreover, making a maintenance plan to improve efficiency of machines and to avoid stoppage of machines.
