“…One of the recommendations was to change the shape of the jig's arms. Their shape in some way resembled the form of parts in particular position (Bedny & Karwowski, ). The proposed innovation brought the orientation of the parts in the considered production operation to a nonsymmetrical orientation, which was described in the MTM‐1 system.…”

This article focuses on the time study of behavioral components of work activity. The method time measurement (MTM‐1) system is a powerful tool for analyzing behavioral components of activity. However, the MTM‐1 system's rules for the selection of basic elements for tasks’ description are necessary but insufficient. Professionals can use the MTM‐1 system rules effectively only after analyzing strategies of a task performance and studying the logical organization of motor and cognitive actions. The results of this study demonstrate that the MTM‐1 system can be used for analyzing behavioral components of activity only after analyzing real strategies of task performance.

“…Kaghan & Bowker go on to discuss the "architecture of complexity" which applies complexity theory to turbulent environments where self-organizing networks of agents "co-evolve" to the "edge of chaos." Bedny, Karwowski, & Kwon (2001) describe the analysis and design of manufacturing assembly operations utilizing the activity theory. "Activity is considered as an organized system with its own structure comprised of interconnected units and the specific relationships among them."…”

“…Vertically-oriented Socio-technical System (Rasmussen 2000) actions and interconnections. Bedny, Karwowski, & Kwon (2001) state that complexity of a task is the major cause of mental workload. These authors state that the evaluation of task complexity includes: 1. workers' concentration and attention on the different elements of the task, 2. emotional stress, 3. compatibility of simultaneously executing different elements of an activity, 4. establishing a commensurable unit for the comparison of tangible and intangible elements, or 5. the duration over which different information must be maintained in working memory.…”

introduced and instructed me in research methods associated with the social sciences, as well as granting me access to departmental laboratory facilities.This dissertation research would not have been possible without the corporate participation of W. M. Kelley Company, Inc. of New Albany, Indiana and Advanced Production Systems, Inc. of Louisville, Kentucky. I wish to thank the management and employees of both companies for their willingness to participate in this research.A very special word of thanks goes to Dr. Hanne Albrechtsen and the collaborative relationship that she fostered between the Ris∅ National Laboratory, Roskilde, Denmark, and myself during this dissertation time frame. The spirit of mutual scientific interest and collaborative research that Dr. Albrechtsen exemplifies shall remain a fundamental academic characteristic that I will always aspire to. This dissertation examines a research objective associated with human performance in agile production systems, with specific attention towards the hypothesis that system outcomes are the causal result of worker human cognition and quality of work life attributes experienced in an agile production system. The development and adoption of world class agile production systems has been an immediate economic answer to the world-wide competitive call for more efficient, more cost-effective, and more quality laden production processes, but has the human element of these processes been fully understood and optimized?Outstanding current literature suggests that the recent movements toward higher standards in systems outcomes (i.e. increased quality, decreased costs, improved delivery schedules, etc) has not been truly evaluated. The human-machine interaction has not been fully comprehended, not to mention quantified; the role of human cognition is still under evaluation; and the coupling of the entire production system with respect to the human quality of life has yielded conflicting messages. viThe dissertation research conducted a longitudinal study to evaluate the interrelationships occurring between system outcomes, applicable elements of human cognition, and the quality of work life issues associated with the human performance in agile production systems. A structural equation modeling analysis aided the evaluation of the hypotheses of the dissertation by synthesizing the three specific instruments measuring the appropriate latent variables: 1. system outcomes -empirical data, 2.human cognition -cognitive task analysis, and 3. quality of work life -questionnaires into a single hypothesized model. These instruments were administered in four (4) waves during the eight month longitudinal study.The study latent variables of system outcomes, human cognition, and quality of work life were shown to be quantifiable and causal in nature. System outcomes were indicated to be a causal result of the combined, yet uncorrelated, effect of human cognition and quality of work life attributes experienced by workers in agile production systems. In addition, this latent var...
