Currently available Lean tools such as Lean Assessments, Value Stream Mapping, and Process Flow Charting focus on system requirements and overlook human behavior. A need is felt for a tool that allows one to baseline personnel, determine personnel requirements and align system requirements with personnel requirements. Our exploratory model--The Personnel Behavior Based Lean Model (PBBL), attempts to ingrain the human perspective into Lean design. The model is both a result of our research into the workings of the human element in Lean production, as well as a tool for research. The model can baseline the current state of personnel and develop a strategy for behavioral change to aid Lean implementation efforts. Accumulation of historic data using the model can help to develop a human capability index in the lines of process capability index. The paper describes the development of the model and subsequent validation of the model through a case study. The case study also serves as a stepping-stone for future work and research suggested at the end of the paper. (Contains 4 tables and 2 figures.)
