KnowWare International Celebrates 20th Anniversary of QI Macros® for Excel

Jay Arthur, President and founder of KnowWare International and developer of QI Macros for Excel, is proud to announce its 20th anniversary in 2017.

Twenty years ago, Jay Arthur left “Baby Bell,” U.S. West, to become a quality improvement consultant. He knew he needed some tools to create control charts, Pareto charts and histograms, so he started experimenting with Excel 97 in Windows 95. Jay discovered a way to program Excel to create the charts his clients needed: QI Macros was born!

Jay designed QI Macros, an innovative user-friendly software that allows users access to the tools they need without learning formulas or becoming statisticians. QI Macros supports more than 100,000 satisfied users in more than 80 countries.

“During the last 20 years we enhanced QI Macros with unique features and adapted to Microsoft upgrades. We aim to contribute towards a hassle-free America with zero waste, zero rework and zero harm,” says President Jay Arthur.
