World Class Master Scheduling: Best Practices and Lean Six Sigma Continuous Improvement

Chapter 1: Understanding the Master Schedule

Master scheduling is probably one of the most important and yet least appreciated processes to control costs in business today.

Techniques in master scheduling cover lots of business process territory, including links to demand planning, financial planning, inventory strategy, customer service, and rules of engagement.

Topics covered in the chapters to come include what good process would look like, how top managers interact with this driver of requirements called master scheduling, and how to implement a high-performance master production scheduling process in your business.
