c) Increases system variation
d) Has no impact to variation
e) None of the above
2) Dynamic complexity includes all the following attributes except:
a) Obvious interventions produce non-obvious consequences
b) The action has similar effects over the short and long run
c) The action has one set of consequences locally but different results in another part of the system
d) The real leverage in most management situations lies in understanding cause and effect dependency and variation
3) Increased uncertainty and variability in a supply chain typically results in
I. Faster deliveries
II. Lower service levels
III. Increased inventory
IV. Lower Costs

5) The Chair of the Quality Department at Motorola University wants to construct a p-chart for determining whether the four faculty members teaching the course are in a state of control concerning the number of students who fail in the course. Accordingly, the Chair sampled 500 final grades from last year for each instructor, and computed the number of failures per instructor as 13, 11, 0, and 16 respectively. Compute the upper and lower standard control limits for this chart.
a) 0.9500 and 0.0500
b) 0.0600 and 0.1400
c) 0.0388 and 0.0012
d) None of the above
6) In general, viable scientific exploration:
a) Is conducted to prove old truths are infallible
b) Is conducted to create a falsifiable model that is able to predict future outcomes
c) Is conducted to create a non-falsifiable model that is able to predict future outcomes
d) Relies on anecdotal evidence to support its claims
e) Is conducted to create models that are unable to predict future outcomes
7) A small pond has just been infected with an invasive species of blue algae. Botanist studying this organism know that it growth doubles everyday and based on this, the pond will be 100% infested in 30 days. Assuming today is the start of day 1, on what date will the pond be 50% infested?
a) Day 2
b) Day 29
c) Day 15
d) Day 30
e) None of the above
8) Referring to the product-process matrix, if a company has a few major products with high demand and a jumbled flow (job shop) process, we know the company:
a) Has a company strategy
b) Is on the diagonal of the matrix
c) Is further in its product life cycle than its process life cycle
d) Is further in its process life cycle than its product life cycle
