Which quality control tool should be used to monitor the current status or end result of a process?
A. Flowchart
B. Scatter diagram
C. Control chart
D. Checklist
正解：C
解説：
Acontrol chartis the primary quality control tool used tomonitor the current status and end results of a process over time.
Control charts, a core component ofStatistical Process Control (SPC), distinguish between:
* Common-cause variation(natural process variation)
* Assignable-cause variation(abnormal, correctable issues)
By plotting data points against upper and lower control limits, control charts help operations managers determine whether a process isstable or out of control.
Why control charts are ideal:
* They provide real-time monitoring
* They detect trends before defects occur
* They support preventive quality management
* They reduce reliance on inspection
Other tools serve different purposes:
* Checklistscollect data
* Flowchartsmap processes
* Scatter diagramsanalyze correlations
Operations Management emphasizes control charts because they supportprocess-based quality, aligning with TQM and Six Sigma philosophies. Instead of fixing defects after they occur, organizations canintervene early
, reducing cost and improving consistency.
Control charts reinforce continuous improvement by enabling data-driven decisions, reducing variability, and stabilizing production processes-making them indispensable in modern quality management systems.

Which function does marketing play in a just-in-time (JIT) organization?
A. JIT marketing focuses on customer-driven quality.
B. JIT marketing synchronizes product demand with assembly.
C. JIT marketing simplifies inventory flow.
D. JIT marketing focuses on producer-driven quality.
正解：A
解説：
In a just-in-time (JIT) organization,marketing focuses on customer-driven quality.
Marketing provides critical input on:
* Customer expectations
* Demand patterns
* Product features
* Service requirements
This information allows operations to design processes that meet actual customer needs rather than internal assumptions. JIT requires precise alignment between demand and production, and marketing ensures that quality is defined externally by customers.
The other options confuse marketing's role with operational execution:
* Inventory flow is managed by operations
* Assembly synchronization is a production function
* Producer-driven quality contradicts TQM principles
Operations Management stresses that JIT succeeds only whenmarketing and operations are tightly integrated, with marketing acting as the voice of the customer.

Which strategy is used by some emergency rooms to overcome customer frustrations about long waiting times?
A. See each patient in the order in which they arrived
B. Screen patients and send the last 25 to another facility
C. Screen patients and schedule follow-up appointments for those who have the most serious injuries
D. Screen patients and fast-track those with minor ailments
正解：D
解説：
Emergency rooms often usescreening and fast-tracking patients with minor ailmentsto reduce perceived and actual waiting times. This strategy is a well-establishedservice operations capacity-management technique.
From an Operations Management perspective, emergency departments facehigh variability in demand and processing times, which leads to congestion and long queues. Treating all patients strictly in arrival order (first-come, first-served) is operationally inefficient because patients require very different levels of care.
Fast-tracking works by:
* Separating low-complexity cases from critical cases
* Allocating dedicated resources to minor treatments
* Reducing bottlenecks at key treatment stages
This approach improvesflow efficiency, patient satisfaction, and throughput without increasing total capacity.
It aligns with queue management principles and the concept ofsegmented service design, where different customer needs are handled through different process paths.
The other options are inferior operationally:
* Scheduling follow-ups for severe cases is clinically unsafe
* Sending patients elsewhere shifts the problem, not solves it
* Strict arrival order ignores service-time variability
Fast-tracking addresses bothoperational efficiencyandperceived service quality, which is particularly critical in high-contact service systems such as healthcare.

Which type of aggregate plan is preferable when a company produces custom or special purpose equipment, one-of-a-kind items, or highly perishable products?
A. A modified sales and operations plan
B. A chase aggregate plan
C. A hybrid aggregate plan
D. A level aggregate plan
正解：B
解説：
Comprehensive and Detailed Explanation (#270 words):
Achase aggregate planis preferable for environments withcustom, one-of-a-kind, special-purpose, or highly perishable outputsbecause production is designed to"chase" (match) demandrather than build inventory.
In a level plan, the firm maintains a constant production rate and uses inventory/backorders to absorb demand fluctuation. That works best when products can be stored economically and demand variability can be buffered. For one-of-a-kind and highly perishable items, inventory is either impossible (custom items) or risky and costly (perishability, obsolescence). Therefore, the operationally sound strategy is to adjust capacity to align output with demand.
This links directly to aggregate planning's purpose: validating whether the system has sufficient capacity to meet expected requests and defining the most appropriate combination of resources. The document also highlights that one aggregate planning mechanism is to"produce reactively (react to demand) - requires flexibility."That is the core logic of a chase strategy.
A chase plan typically uses capacity levers like hiring/layoffs, subcontracting, flexible staffing, and overtime-chosen based on the duration and magnitude of demand changes. It prioritizes responsiveness and minimal inventory, which is essential when holding finished goods is undesirable or infeasible.

What are two common drawbacks of implementing an enterprise resource planning (ERP) solution?
Choose 2 answers
A. It must always be customized and too much customization may slow down projects.
B. It takes a long time to implement and to see any benefits.
C. It requires extensive, often complex, training.
D. The cost savings and/or payback is impossible to measure in terms of bottom line.
正解：B、C
解説：
Comprehensive and Detailed Explanation (#270 words):
Two widely recognized drawbacks of ERP implementations are that theytake a long time to implement (and to realize benefits)andrequire extensive, often complex training-optionsAandB.
ERP systems integrate data and processes across functions (planning, procurement, production, inventory, finance, distribution). That integration is valuable, but it also makes implementation complex: processes must be aligned, data standardized, roles clarified, and change managed across departments. As a result, organizations often experience long project timelines before stable adoption and measurable benefits occur.
Training is a major burden because ERP changes how people work day-to-day. Users must learn new transaction flows, reporting logic, and discipline in data entry. Without strong training, adoption collapses into workarounds, bad data, and loss of trust in the system.
This connects to the operations principle that planning and control systems are "mechanisms and operating logics" used to manage resources and supplies over time to meet requests. ERP is one such enabling infrastructure-but it must support operations rather than become a constraint.
While customization can be an issue in some cases, the most universal drawbacks across organizations remain time-to-valueandtraining complexity, makingA and Bthe best answers.
