- An employee
- Factory layout
- A customer
3. The Shingo approach to quality control depends on which of the following?
- Use of statistically based approaches to quality control
- Use of source inspection on 100% of the items produced
- Extensive use of control charts
- Use of a sophisticated method of acceptance sampling
4. Statistical Process Control (SPC) and data from the actual process to statistically monitor the process over time are employed during which step of the DMAIC cycle?
5. 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?
- Operating revenue
- Unit cost
- Net Profit
6. The DMAIC cycle of Six Sigma is similar to which of the following quality management topics?
- External benchmarking
- ISO 9000
- Continuous improvement
7. The Shingo system of quality control relies heavily on failsafe procedures or devices called what?
8. identifying critical to quality characteristics (CTQs) takes place in which step of the DMAIC methodology?
9. According to the theory of constraints which of the following is a FINANCIAL measurement that can be used to measure the firm's ability to make money?
- Cash flow
- Operating expenses
10. Goldratt’s theory of constraints (TOC) could be restated using which of the following?
- A system with constraints will not be able to achieve its goals
- Any system is limited in achieving more of its goals by a very small number of constraints
- A system constraint cannot be identified and thus cannot be improved
- Continuous adjustments after a constraint problem is solved will cause more problems
11. The idea that statistical methods of quality control, including six sigma, does not prevent defects, is central to what alternative quality system?
- SQC methods
- Deming PDCA cycle
- DMAIC cycle
- Shingo System
12. A bottleneck in a manufacturing process may be targeted and eliminated by employing which of the following?
- Install more efficient equipment where capacity is less than the demand
- Increase labor equally throughout the system
- Increase the capacity of a non bottleneck resource
- Increase the idle time of a capacity constrained resource in the system
13. Which of the following is a focusing step of Dr. Eli Goldratt's theory of constraints?
- Do not modify a process after improvement of a constraint is achieved.
- Isolate constraints to reduce the constraint’s capacity.
- Align the whole system to support processes prior to the constraint.
- Identify system constraints that prevent the system from achieving its goal
14. According to Goldratt, which of the following is defined as “any resource whose capacity is less than the demand placed on it”?

- Buffer resource
- Non bottleneck resource
- Capacity constrained resource
