What would be an organization's next step after it has revised or implemented new operations?
A. Follow up to make sure the new operation resolves quality problems
B. Reverse the order of the operation to determine that all workers know how to complete the operation
C. Conduct a final analysis of the existing operation one more time
D. Revise the order of the operation before putting it into service to ensure the order of the operation
正解：A
解説：
After implementing revised or new operations, the correct next step is tofollow up to ensure that the new operation resolves quality problems.
Operations Management emphasizes that implementation alone does not guarantee improvement. Post- implementation follow-up is required to:
* Verify performance improvements
* Detect unintended consequences
* Confirm quality objectives are met
* Ensure process stability
This step is central tocontinuous improvementand aligns with PDCA (Plan-Do-Check-Act) and DMAIC cycles.
The other options are ineffective or redundant:
* Reversing operation order adds no value
* Revising before use contradicts implementation
* Re-analyzing the old process ignores the change
Follow-up transforms change into learning and ensures operational improvements are sustained over time.

What is meant by "duration of the change"?
A. The percentage of normal operating capacity
B. The fiscal impact of the change on the strategic plan
C. The size of the change needed
D. The length of time one expects to need the different level of capacity
正解：D
解説：
Comprehensive and Detailed Explanation (#270 words):
In capacity and aggregate planning,"duration of the change"refers tohow long the organization expects to operate at a different capacity level-higher or lower than normal. This is exactly what optionAstates.
In operations planning, managers must decide not onlyhow muchcapacity to change, but alsofor how longthe change will be required. That time horizon directly drives which capacity option is appropriate. If the change is short-lived, the firm typically chooses flexible, reversible options (overtime, temporary labor, subcontracting). If the change is long-lived, it may justify structural commitments (new equipment, new facility, permanent staffing).
This ties to hierarchical planning logic: the planning and control system exists to "harmonize the client's requests with the available resources" and uses staged planning levels (strategic capacity, aggregate planning, operational planning, scheduling). At the aggregate planning level, the organization validates whether it has enough capacity to meet expected workloads and selects a combination of resources.
Duration matters because longer changes increase the cost of relying on short-term measures (fatigue, overtime premiums, quality risk) while making long-term investments more economically rational. In short:
duration is the time component of the capacity decision, and it guides the selection of the most suitable planning lever.
質問 # 72
When is capacity measurement at the best operating level?
A. When the average unit cost is minimized
B. At maximum capacity
C. At the minimum point of the cost curve
D. When the total cost is minimized
正解：A
解説：
Comprehensive and Detailed Explanation (#250 words):
Thebest operating levelof capacity occurswhen the average unit cost is minimized.
In Operations Management, the best operating level reflects the most economical output rate for a process or facility. At this level:
* Fixed costs are spread efficiently
* Variable costs are controlled
* Congestion and inefficiencies are minimized
Operating below this level leads tounderutilizationand high unit costs, while operating above it often causes overcrowding, overtime, equipment breakdowns, and quality problems, which increase costs.
OptionAis incorrect because the minimum point of the total cost curve does not necessarily correspond to minimum average unit cost.
OptionBis incorrect because maximum capacity typically increases costs due to inefficiencies.
OptionDfocuses on total cost, not unit efficiency.
Thus, the best operating level balances efficiency and flexibility, ensuring sustainable performance and cost control.
質問 # 73
Which two types of operations include repetitive processes?
Choose 2 answers
A. Project process
B. Continuous process
C. Batch process
D. Line process
正解：B、D
解説：
Line processesandcontinuous processesare the two operational process types characterized byhighly repetitive activities.
Aline processinvolves standardized products moving through a fixed sequence of steps. Each workstation performs the same task repeatedly, making it ideal for high-volume, low-variety production. Examples include automobile assembly lines and consumer electronics manufacturing.
Acontinuous processgoes a step further, operating24/7 with extremely high volume and minimal variation
. Production flows continuously rather than in discrete units. Industries such as oil refining, chemicals, and paper manufacturing use continuous processes.
The other options are not primarily repetitive:
* Project processesare unique, one-time efforts (e.g., construction projects)
* Batch processesinvolve moderate repetition but frequent changeovers between batches Operations Management classifies processes based onvolume and variety. Line and continuous processes sit at the high-volume, low-variety end of the spectrum, making repetition unavoidable and necessary for efficiency.
Repetitive processes enable:
* High labor productivity
* Low unit cost
* Process automation
* Consistent quality
However, they also require careful work system design to avoid worker fatigue and quality drift.

What is a major factor in the decision to locate a business near its primary market territory?
A. Proximity to a community center
B. Proximity to labor
C. Proximity to customers
D. Proximity to parks
正解：C
解説：
Comprehensive and Detailed Explanation (#250 words):
The dominant factor in locating a business near its primary market territory isproximity to customers.
From an Operations Management perspective, closeness to customers:
* Reduces transportation and delivery time
* Improves service responsiveness
* Enhances customer satisfaction
* Supports demand growth
This is especially critical for service organizations and distribution-intensive businesses, where customer access and speed are competitive advantages.
While proximity to labor is important, it does not define market territory. Community centers and parks are not operational drivers.
Locating near customers aligns capacity with demand, minimizes logistics complexity, and strengthens market presence.
