ProMES has been implemented successfully in various countries, settings and branches. The studies were conducted by independent research groups both from academia and the applied world. Well-known companies and organizations like 3M, GfK, Leica Microsystems, the US Air Force, and SwissLife participated in one of the largest research studies in management history.
The study (see Pritchard and colleagues, 2008) shows that ProMES leads to strong and stable improvements in team productivity and organisational effectiveness. The teams from the study showed large productivity improvements averaging a productivity improvement of over 200%!
The effectiveness of ProMES is shown in the graph below. It shows the average improvement curve of 83 studies conducted between 1987 and 2007.
The productivity during baseline (productivity data measured but not communicated to the teams) averaged at around 50 effectiveness points (EP). After feedback productivity increased heavily to a point of diminishing returns. In contrast to other methods, productivity change is stable in the long run. Moreover, the researchers found in various studies, that ProMES improves job satisfaction, leads to lower perception of stress and fatigue and creates a positive working climate. Explanations for these effects are role and goal clarity, clear priorities and thus less conflict.
