9. Continuous improvement
A static manufacturing process is, over time, a degrading process. Actively improving your line today ensures your defect rates remain under control tomorrow. Market demands for higher reliability and lower costs dictate that we cannot simply maintain the status quo; we must continuously and systematically identify and eliminate operational waste.
This chapter defines the engineering methodologies for systemic Continuous Improvement. True continuous improvement relies on structured, data-driven frameworks to isolate the root causes of failure and engineer permanent solutions that prevent recurrence.
