1) Organizational strategy should be determined without considering the realities of
functional area strengths and weaknesses since they can be changed to meet our
strategy.
2) Line balancing is a major factor in the design and scheduling of low-volume systems
because of batch processing.
3) Therbligs are basic elemental motions.
4) Ultimately the overriding factor in choosing a strategy in aggregate planning is
overall cost.
5) In the decision-making hierarchy, scheduling decisions are the final step in the
transformation process before actual output occurs.
6) In the lean philosophy, the larger the lot size, the easier it is to schedule.
7) The equation 3xy = 9 is linear.
8) The estimation of costs is generally most difficult when the ___________ process
has been chosen.

A.single family
B.apartments
C.condos
D.either single family or apartments
E.either apartments or condos
