Information : Statistical Process Control/Design of Experiments Process
Nascote has applied SPC since 1988 to interpret and control process capabilities and quality. Various statistical methods helped monitor the processes and predict process variations, thereby controlling the quality of the product. Nascote initiated a successful approach to SPC, with over 95% of the workforce trained in basic SPC and more than 25% of the workforce trained in advanced SPC.
The basic training consisted of eight hours of classroom training including the collection, analysis, plotting, and use of the data to understand and control manufacturing processes. The advanced SPC training was also an eight-hour training course with emphasis on process capability studies and analysis. Nascote found that a workforce well trained in SPC controls processes and communicates quality requirements to coworkers more efficiently.
In 1992, Nascote further enhanced its quality assurance by generating a formalized statistical quality assurance procedure and by training all supervisors and engineers in Design of Experiments (DOE) -Taguchi methods. The DOE allowed the company to introduce new processes/products into the system with predictable and high-quality results. The disciplined requirements of the DOE ensured repeatability and reduction of process variations. Increased use of DOE was part of the ongoing pursuit for process variation reduction and Continuous Quality Improvement at Nascote Industries.
