OPSY 5315 RAO Exam 2 | Complete Practice Questions,
Correct Answers & Detailed Rationales (2026/2027)
Question 1
Operations management is best defined as the set of activities that
creates value in the form of goods and services by transforming:
• A. Inputs into outputs.
• B. Financial capital into debt securities.
• C. Raw data into marketing intelligence.
• D. Consumer complaints into warranty claims.
Correct Answer: A. Inputs into outputs.
Detailed Rationale: Operations management (OM) focuses on
managing the transformation process that converts inputs (such as
labor, materials, equipment, and land) into finished goods and services.
Question 2
Productivity is calculated as:
• A. Outputs divided by inputs.
• B. Inputs divided by outputs.
• C. Total revenue minus total cost.
• D. Actual output divided by design capacity.
Correct Answer: A. Outputs divided by inputs.
,Detailed Rationale: Productivity measures operational efficiency by
comparing the quantity of goods and services produced (output) with
the resources used to produce them (input).
Question 3
Which of the following represents a multifactor productivity measure?
• A. Output divided by labor alone.
• B. Output divided by the sum of labor, capital, and material.
• C. Output divided by energy consumption only.
• D. Sales revenue divided by advertising expense.
Correct Answer: B. Output divided by the sum of labor, capital, and
material.
Detailed Rationale: Multifactor productivity uses more than one
resource input (typically labor, capital, and materials) in the
denominator, expressed in common units like dollars, whereas single-
factor uses only one input.
Question 4
A key operational distinction between goods and services is that
services:
• A. Can be easily inventoried and stored for future sale.
• B. Are typically consumed at the time of production and involve
high customer interaction.
• C. Have zero labor content.
• D. Are always capital-intensive with no quality variability.
,Correct Answer: B. Are typically consumed at the time of production
and involve high customer interaction.
Detailed Rationale: Services are intangible, perishable, and usually
consumed simultaneously with their production, unlike manufactured
goods which can be stored in inventory.
Question 5
In operations strategy, a "core competency" refers to:
• A. A set of unique skills, talents, and capabilities that a firm does
better than its competitors.
• B. The minimum legal compliance standards required to operate a
facility.
• C. The total annual fixed cost budget.
• D. The geographic location of the corporate headquarters.
Correct Answer: A. A set of unique skills, talents, and capabilities that a
firm does better than its competitors.
Detailed Rationale: Core competencies form the strategic foundation of
a business, allowing it to deliver unique value to customers that
competitors cannot easily replicate.
Question 6
Forecasting methods that use historical data and mathematical models
to predict future demand are classified as:
• A. Qualitative forecasting.
• B. Quantitative forecasting.
, • C. Delphi methods.
• D. Executive opinion panels.
Correct Answer: B. Quantitative forecasting.
Detailed Rationale: Quantitative forecasting relies on mathematical
models and historical time-series or associative data, whereas
qualitative methods rely on judgment and intuition.
Question 7
In a 3-month moving average forecast, if actual demands for the past
three months were 100, 110, and 120, what is the forecast for the next
month?
• A. 100
• B. 110
• C. 120
• D. 115
Correct Answer: B. 110
Detailed Rationale: Forecast = (100 + 110 + 120)/3 = 330/3 =
110. The moving average takes the arithmetic mean of the most recent
𝑛 periods.
Question 8
Weighted moving averages are often preferred over simple moving
averages because weighted moving averages:
• A. Require zero historical data points.
