Allan H. Mogensen, known as Mogy, (Pennsylvania, May 1901 - March 1989) was an American industrial engineer and authority in the field of work simplification[1] and office management.[2] He is noted for popularizing flowcharts in the 1930s, and is remembered as "father of work simplification"[3][4]

Life and work[edit]

In the 1920s Mogensen received his BA in Industrial Engineering at Cornell University, where he had studied the methods of Frank Bunker Gilbreth, Sr.. Afterwards he started as industrial engineering consultant, among other places at the Eastman Kodak.[5] In his consultancy practice he experienced, that improvements made by employees on the work floor were the most successful.[4] With other principles he developed the concept of work simplification, which he explained in his 1932 book Common sense applied to motion and time study.

After conducting training sessions in large firms, in 1937 Morgensen, Lillian Gilbreth and associates started training business people in work simplification methods and business process modeling in his Work Simplification Conferences in Lake Placid, New York.[6] In 1944 Art Spinanger attended Mogensen's classes, and back at Procter and Gamble started their remarkable "Deliberate Methods Change" program.[7][8][9] An other of their students was Benjamin S. Graham, who started applying scientific management and industrial engineering techniques to offices and clerical work in factories, and coined the concept of paperwork simplification.[10]

In the 1930s Mogensen further experimented with time and motion studies using motion pictures.[11] Early 1940s Mogensen was noted for making movies of operations in hospitals, where he discovered that surgeons could work faster by avoiding lost motions, and in doing so reduce the mortality rate.[12] At Lake Placid Mogensen kept organizing the Work Simplification Conferences for almost 50 years.[4]

  • In order to achieve measurement, tools are needed and the most important of these is the process chart.…Once a process chart has been drawn up, common sense is all that is needed to improve efficiency and better the process being examined.…The process chart then, is the lifeblood of work simplification. It is an irreplaceable tool. It is a guide and stimulant. It takes time to properly utilize but there is absolutely no doubt that it works.
