theory of constraints

OPS 571 WEEK 6 QUIZ 1 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. • Identify system constraints that prevent the system from achieving its goal. • Isolate constraints to reduce the constraint- capacity. • Align the whole system to support processes prior to the constraint. Correct • 2 According to Goldratt, which of the following is defined as “any resource whose capacity is less than the demand placed on it”? • Buffer resource • Bottleneck resource • Capacity-constrained resource • Nonbottleneck resource Correct • 3 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? • Sales • Inventory • Operating expenses • Cash flow Correct • 4 The Shingo system of quality control relies heavily on fail-safe procedures or devices called what? • Checklists • DPMO- • CTQs • Poka-yokes Correct • 5 Goldratt- theory of constraints (TOC) could be restated using which of the following? • Continuous adjustments after a constraint problem is solved will cause more problems • Any system is limited in achieving more of its goals by a very small number of constraints • A system with constraints will not be able to achieve its goals • A system constraint cannot be identified and thus cannot be improved Correct • 6 The idea that statistical methods of quality control, including six-sigma, does not prevent defects, is central to what alternative quality system? • Shingo System • SQC methods • Deming PDCA cycle • DMAIC cycle Correct • 7 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 Correct • 8 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 • Net Profit • Unit cost • Operating revenue Correct • 9 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? • Define • Measure • Control • Improve Correct • 10 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 the capacity of a nonbottleneck resource. • Increase labor equally throughout the system. • Increase the idle time of a capacity-constrained resource in the system. Correct • 11 According to the theory of constraints, which of the following would be included in the Throughput operational measurement? • Goods sold • Finished goods • Raw materials • Work in process Correct • 12 The DMAIC cycle of Six Sigma is similar to which of the following quality management topics? • External benchmarking • ISO 9000 • Continuous improvement • SERQUAL Correct • 13 Identifying critical-to-quality characteristics (CTQs) takes place in which step of the DMAIC methodology? • Define • Analyze • Measure • Improve Correct • 14 According to the theory of constraints which of the following can be a CCR? • A customer • Factory layout • Product design • An employee Correct • 15 Which of the following are examples of Goldratt- Rules of Production Scheduling? • An hour saved at a bottleneck is a mirage • Nonbottlenecks govern throughput • Utilization and activation are the same • Balance flow, not capacity Correct
