152. Examples of constraints include:
a. insufficient demand for your product.
b. an internal policy that slows response time to customer demand.
c. a process operation that acts as a bottleneck, slowing the delivery of
product to the customer.
d. insufficient training resources, preventing adequate job skills.
e. all of the above

153. Which of the following is NOT a basic assumption related to
Constraint Management?
a. Systems have goals and corresponding necessary conditions
required to achieve the goals. We must identify these to effectively
improve the system.
b. We must maximize the performance of each link in the chain to
improve the system.
c. The performance of the system is dictated by the “weakest link” in the
system.
d. None of the above.
154. Constraint Management’s focusing steps, in order, are:
a. Identify, Elevate, Subordinate, Exploit, Repeat
b. Plan, Do, Check, Act
c. Identify, Exploit, Subordinate, Elevate, Repeat
d. Identify, Elevate, Subordinate, Exploit
155. Once we have identified the constraint, and taken actions to make the
most of its resources, we should:
a. define parameters for other system elements to complement the
constraint’s needs.
b. improve the capacity of downstream processes.
c. regularly verify that the constraint has not moved.
d. all of the above
e. choices a and c

156. Buffers are used to:
a. increase capacity.
b. decrease cycle time of a constraint.
c. ensure that the constraint is not waiting for materials.
d. increase the system cycle time.

157. Buffers should:
a. be used at each stage of the process.
b. be used at the constraint, to protect against upstream cycle time
variation.
c. never be used in Constraint Management.
d. protect the constraint from being overworked.
