Handbook of Management Scales/Pull
Pull (alpha > 0.7; composite reliability = 0.88; average variance extracted = 0.66)
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.
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 facilitating JIT production including kanban cards which serves as a signal to start or stop production.
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.
- Production is "pulled" by the shipment of finished goods.
- Production at stations is "pulled" by the current demand of the next station.
- We use a "pull" production system.
- We use Kanban, squares, or containers of signals for production control.

The last item might be formative rather than reflective, because it doesn't react to other signals than those mentioned.
