"Searching for ways to improve productivity has engaged leaders, managers, teachers, and everyone else concerned with human performance for hundreds of years. Not surprisingly, large numbers of methods for productivity improvement have been proposed and adopted. Some have captured our attention for a while, but few have done so for long, and even fewer have been carefully scrutinized by the standards of our science. The productivity measurement and enhancement system (ProMES) is the rare exception. Robert Pritchard, his students, and colleagues in industry and government, have developed, implemented, refined, and then meticulously documented the effectiveness of ProMES.
This 25-year effort meets the highest standards of those who demand evidence for claims of impact on productivity improvement. The success of ProMES can be attributed to grounding the system in well-established psychological principles providing practices and procedures that incorporate these principles into the behavioral routines of people at work. The evidence is clear; ProMES works." -
