TRUE$/$FALSE$.$ Write $\text{'}$T$\text{'}$ if the statement is true and $\text{'}$F$\text{'}$ if the statement is false.

$1)$ TPS stands for Total Production Streamlining. $1)$

$2)$ Product storage is an example of waste, in the sense that no value is added. $2)$

$3)$ In a JIT system, product inspection adds value by identifying defective items. $3)$

$4)$ Customer demand will always remain an unknown, so it is not considered a source of variation. $4)$

$5)$ Variability in manufacturing can occur because engineering drawings or specifications are

incomplete or inaccurate.

$5)$

$6)$ A push system means providing the next station with exactly what is needed when it is needed. $6)$

$7)$ JIT brings about competitive advantage by faster response to the customer regardless of cost$.7)$

$8)$ Many suppliers feel that having a variety of customers is better than being tied to long$-$term

contracts with one customer.

$8)$

$9)$ JIT systems carry inventory just in case something goes wrong. $9)$

$10)$ Hidden problems are generally uncovered during the process of reducing inventory. $10)$

$11)$ Level scheduling means producing at a constant rate, regardless of customer demands. $11)$

$12)$ The number of kanbans decreases as safety stock is increased. $12)$

$13)$ A kanban system requires little variability in lead time because shortages have their impact on the

entire productive system.

$13)$

$14)$ The quality management tool called poka$-$yoke is not relevant to JIT systems. $14)$

$15)$ Because most services cannot be inventoried, there is little place for JIT to help service

organizations achieve competitive advantage.

$15)$

$16)$ When implemented as a comprehensive manufacturing strategy, JIT, TPS$,$ and lean systems sustain

competitive advantage and result in increased overall returns.
