1. Once efficiency has been achieved, effectiveness improvements must begin immediately and continue for the life cycle of the enterprise.
a. True
b. False
2. In a typical business, it is not unusual to find isolated parts of the system running at peak efficiency (95 to 100 percent). However, efficiency for the entire system is usually less than 40 percent. This often happens because the more efficient operations create problems (such as bottlenecks or increased inventory) for the system as a whole.
a. True
b. False
3. When making a system more efficient, the whole system must be considered to avoid sub-optimization. This "system" focus must go beyond your business processes to customers and suppliers.
a. True
b. False
4. The 6S process (sift, sort, shine, standardize, sustain, and safe), or simply 6S, is a structured program to systematically achieve total organization, cleanliness, and standardization in the workplace.
a. True
b. False
5. The seven forms of waste in business are overproduction, waiting, transport, inappropriate processing, unnecessary inventory, unnecessary motion, and defects.
a. True
b. False
6. If the typical workday is 8 hours, and if lunch and breaks take up an hour per day, then available working time (AWT) will be 7 hours x 60 minutes = 420 minutes per day. Takt time for this process where the customer demand is projected to be 35 pieces per day is 15 minutes per piece.
a. True
b. False
7. Cycle time ("order-to-deliver cycle") is the total time from the beginning to the end of the process, as defined by you and your customer. It includes process time, during which a unit is acted upon to bring it closer to an output, and delay time, during which a unit of work is waiting for the next action.
a. True
b. False
8. In pure manufacturing terms, JIT is a material requirement planning approach in which hardly any inventory of parts or raw materials is kept at the factory and little to no incoming inspection of parts or raw mate1ial occurs.
a. True
b. False
9. JIT requires increased reliance on a more responsible, better-trained, and better-educated workforce. Ultimately, in order to implement a JIT system successfully, quality problems must be virtually eliminated, setup times must be drastically cut throughout the operation, and other sources of production fluctuations must be significantly reduced across the board.
a. True
b. False
10. Kanban is a way of controlling inventory. It works as a signal to replace what has been used. As an inventory control mechanism, it provides an ideal way of exposing problems or opportunities for improvement.
a. True
b. False
