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.
Question 2
Which work system acknowledges the benefits of employee proficiency?
Correct Answer: C
Comprehensive and Detailed Explanation (#250 words): Labor specializationacknowledges the benefits of employee proficiency by allowing workers to focus on specific tasks, increasing skill, speed, and consistency. In Operations Management, labor specialization: * Reduces learning time * Increases productivity * Improves quality consistency * Lowers unit costs Employees become highly proficient through repetition and experience. This principle underpins early scientific management and remains relevant in many high-volume environments. The other options are outcomes or enablers, not work systems: * Employee longevity is a result, not a system * Enhanced relations support performance but do not define task design * Lower operating cost is a consequence of specialization While specialization can create efficiency, it must be balanced with job design strategies (e.g., enrichment or rotation) to avoid fatigue and disengagement.
Question 3
What are two common drawbacks of implementing an enterprise resource planning (ERP) solution? Choose 2 answers
Correct Answer: A,B
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.
Question 4
Which statement is true about capacity requirements planning (CRP)?
Correct Answer: D
The correct statement aboutCapacity Requirements Planning (CRP)is thatavailable capacity is compared to calculated workloads of relevant items. CRP is a planning technique used after material requirements planning (MRP). While MRP determineswhat andwhenmaterials are needed, CRP verifies whether the organization hassufficient capacity-in terms of machines, labor, and work centers-to execute the planned production schedule. CRP works by: * Translating planned orders into workload requirements * Assigning those workloads to specific work centers * Comparing required capacity with available capacity * Identifying overloads or underutilization The incorrect options misrepresent CRP: * CRP does not create capacity; it evaluates feasibility * Human capital adequacy is part of workforce planning, not CRP's primary role * CRP evaluates workloads in relation to the whole system, not isolated items Operations Management emphasizes CRP as afeasibility check, ensuring that production plans are realistic and executable before release to the shop floor.
Question 5
Which formula would indicate that a fast-food restaurant was performing at, above, or below its benchmark?
Correct Answer: B
Comprehensive and Detailed Explanation (#250 words): The formulaActual output / standard outputindicates whether a fast-food restaurant is performingat, above, or below its benchmark. This ratio compares real performance against a predefined standard. A value: * Equal to 1 means performance meets the benchmark * Greater than 1 means performance exceeds expectations * Less than 1 indicates underperformance Benchmarks are critical in Operations Management for: * Performance evaluation * Labor productivity measurement * Process control The other formulas measure utilization, velocity, or productivity, but do not directly reference a benchmark. By comparing actual output to standard output, managers can quickly assess operational effectiveness and identify areas requiring corrective action.
