• Increase labor equally throughout the system.
• Increase the idle time of a capacity-constrained resource in the system.

2) The Shingo approach to quality control depends on which of the following?

• Extensive use of control charts
• Use of source inspection on 100% of the items produced
• Use of statistically based approaches to quality control
• Use of a sophisticated method of acceptance sampling

3) According to the theory of constraints which of the following can be a CCR?

·         An employee

• Product design

4) According to the theory of constraints, which of the following is an OPERATIONAL measurement that can be used to measure the firm's ability to make money?

• Inventory
• Unit cost
• Operating revenue

·         Net Profit

5) Which of the following is a focusing step of Dr. Eli Goldratt's theory of constraints? 

• Isolate constraints to reduce the constraint’s capacity.
• Do not modify a process after improvement of a constraint is achieved.
• Identify system constraints that prevent the system from achieving its goal.

·         Checklists

9) Goldratt’s theory of constraints (TOC) could be restated using which of the following?

·         Continuous adjustments after a constraint problem is solved will cause more problems

• A system constraint cannot be identified and thus cannot be improved

·         Any system is limited in achieving more of its goals by a very small number of constraints
