Handbook of Management Scales/Supplier development

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 developing suppliers so they can be more involved in the production process of the focal firm.

Comments
Average variance extracted is too low. The items are quite heterogenous and sometimes they appear to be too far from measuring supplier development.
