WGU Operations-Management Practice Exam Questions & Answers

When conducting a location analysis, firms must consider proximity to sources of supply and site considerations as key capacity-related factors.

Proximity to sources of supply affects:

Transportation cost and reliability

Lead times

Inventory requirements

Production continuity

Reliable supply access directly influences effective capacity by reducing disruptions and variability.

Site considerations include:

Land availability and cost

Infrastructure and utilities

Expansion potential

Zoning and regulatory constraints

These factors determine how much capacity can be installed, expanded, and operated efficiently over time.

The other options are less relevant:

Throughput time is a process performance metric

Employee relations are important but not capacity measurement concepts

Operations Management emphasizes that capacity decisions are long-term and capital-intensive. Poor location choices constrain future capacity, flexibility, and growth.

For service organizations, proximity to customers and quality-of-life issues are two dominant factors in location decisions.

Unlike manufacturing, service operations require direct customer contact. Being close to customers reduces travel time, improves convenience, enhances responsiveness, and increases perceived service quality. Examples include hospitals, banks, restaurants, and consulting offices, where location accessibility directly influences demand.

Quality-of-life issues---such as education, healthcare, housing, safety, climate, and cultural amenities---affect the ability to attract and retain skilled service employees. Human capital is a critical input in service operations, and workforce availability often outweighs cost considerations.

The other options are less relevant:

Manufacturing proximity matters mainly for production facilities

Warehouse storage is a logistics concern, not a service driver

Operations Management emphasizes that service location decisions balance customer access and employee satisfaction, since both directly influence service quality, productivity, and long-term sustainability.

Assignable causes of variation indicate that out-of-control signals were found in the process.

In Statistical Process Control (SPC), variation is classified into:

Common causes (natural, inherent to the process)

Assignable causes (specific, identifiable, and correctable)

Assignable causes signal that something unusual has occurred, such as equipment malfunction, incorrect material, improper setup, or procedural deviation. These causes result in process instability and are detected using control charts when data points fall outside control limits or exhibit non-random patterns.

Importantly, assignable causes do not automatically blame individuals. TQM philosophy stresses that most quality problems are systemic, and the goal is to identify root causes, not assign fault.

The other options are either overly specific or misleading:

A computer virus is not a standard quality interpretation

Operator fault may or may not be the cause

Equipment issues are one possible assignable cause, not the definition

Recognizing assignable causes allows organizations to take corrective action, restore process stability, and prevent recurrence---key objectives of quality control.

The feasibility analysis phase evaluates whether a proposed project is technically, financially, and operationally viable.

During feasibility analysis, organizations assess:

Cost-benefit justification

Resource availability

Technical constraints

Operational impact

Risk and uncertainty

This phase prevents organizations from committing to projects that:

Are too costly

Lack capability support

Conflict with operational capacity

Fail to deliver strategic value

Planning and execution only proceed if feasibility criteria are satisfied.

In Operations Management, feasibility analysis is especially critical for projects involving:

Capacity expansion

New facilities

System implementations

Process redesign

It serves as a decision gate that protects organizational resources and ensures disciplined project selection.

Capacity planning is the process that helps organizations identify and plan the actions required to meet current and future customer demand.

In Operations Management, capacity planning ensures that an organization has the right amount of resources at the right time. These resources may include labor, equipment, facilities, and technology.

Capacity planning involves:

Forecasting demand

Evaluating existing capacity

Identifying capacity gaps

Selecting capacity adjustment strategies (e.g., overtime, subcontracting, expansion)

Without capacity planning, organizations risk:

Excess capacity and high costs

Insufficient capacity and lost sales

Poor service levels and customer dissatisfaction

Production capacity alone is static, while capacity planning is dynamic and forward-looking. Economic conditions influence demand but do not provide actionable operational plans.

Capacity planning aligns operations strategy with business strategy and supports sustainable growth.
