Process Development, Process Capability
This paper describes a project undertaken by an industrial company to investigate cost effective options to stitching fabric using sewing machines. They had trained a cadre of operators with many years of stitching experience. They had several specialized sewing machines that served the company well. However, during recent times it was becoming difficult to hire operators who knew stitching and also had experience in this trade. The sewing machines were wearing out with age. There were no spares or backups available for these machines. The company had to cannibalize parts from old machines to keep the sewing department operational. It became apparent to management that a new process and equipment would have to be considered to remain in business.
