In fact, there are many differences. One major difference between KED and all of these programs is that we have a unique and proven approach and methodology that utilizes and integrates engineering, psychology, and business principles from different methods. In addition, programs such as Lean, Six Sigma, TQM, etc. focus on specific methods and techniques but do not address the behavioral changes required from management and employees as they relate to recovering and sustaining improvement opportunities. Other consultants do not all look at every aspect of the process such as the human-machine interaction, the changes and impact the technical and human aspects of the operation, effects on safety and productivity, work balancing and bottleneck reduction.
