Seven Key Tools for Breakthrough Improvement

The Magnificent Seven is All You Need

Over the years, in project after project, I have found that I only needed seven tools to solve virtually any operational problems involving delay, defects and deviation. Once in a great while I might need another tool, but I had to look it up because I had long forgotten it. You can easily create breakthrough improvements using these seven tools and QI Macros for Excel.
