Handbook of Management Scales/Total productive and preventive maintenance

Total productive/preventive maintenance (alpha > 0.7; composite reliability = 0.77; average variance extracted = 0.45) Description The research takes a step toward clarifying the concept of lean production and develops and validates a multi-dimensional measure of lean production. The 10 distinct dimensions of a lean system are continuous flow, customer involvement, employee involvement, JIT delivery by suppliers, pull, set up time reduction, statistical process control, supplier development, supplier feedback, and total productive/preventive maintenance. Definition Lean production is an integrated socio-technical system whose main objective is to eliminate waste by concurrently reducing or minimizing supplier, customer, and internal variability. This dimension of lean production is about addressing equipment downtime through total productive maintenance and thus achieve a high level of equipment availability. Items Please indicate the extent of implementation of each of the following practices in your plant. (1) no implementation; (2) little implementation; (3) some implementation; (4) extensive implementation; (5) complete implementation. We dedicate a portion of everyday to planned equipment maintenance related activities We maintain all our equipment regularly We maintain excellent records of all equipment maintenance related activities We post equipment maintenance records on shop floor for active sharing with employees Source Shah/Ward (2007): Defining and developing measures of lean production.
