Theory and practice for the implementation of 'in-house', continuous improvement participatory ergonomic programs.

This paper presents a case study of an implementation of a participatory ergonomics program in a public service agency. The objective of the study was to develop a theoretical model and related design principles for the implementation of 'in-house', continuous improvement participatory programs. The proposed model is based on the behavioral cybernetic theory of learning (Smith and Smith, 1966, Cybernetic Principles of Learning and Educational Design held, Rhinehart and Winsten, New York) and emphasizes the concepts of action, feedback, feedback control, and individual learning as essential for a progression from external regulation (by outside experts) to internal regulation (by organizational members) of participatory programs. Results support the proposed model, but do suggest an expansion of the model to include macro-level organizational variables as additional factors necessary for developing internally regulated participatory programs. Results have led to the specification of several design principles for implementing 'in-house', continuous improvement participatory programs.
