WGU Operations-Management Exam Questions

The appropriate hybrid layout is group technology.

Group technology combines the efficiency of product layouts with the flexibility of process layouts by grouping similar products into families and arranging workstations into cells. Each cell is designed to handle a specific family of products from start to finish.

In the case of prefabricated homes:

Production volumes are low

Product designs share similarities

Space is constrained

Material handling must be minimized

Group technology reduces:

Movement of materials

Setup times

Work-in-process inventory

Congestion in limited spaces

The other options are not layouts:

Process performance metrics are measurement tools

Manufacturing technology refers broadly to automation

Statistical reduction control is not a recognized layout concept

Operations Management promotes group technology as an effective solution for low-volume, moderate-variety environments, especially where space efficiency and flow improvement are critical.

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 when marketing and operations are tightly integrated, with marketing acting as the voice of the customer.

When demand rises suddenly to 140% of existing capacity, the firm must rely on short-term, flexible capacity options to respond quickly.

The two appropriate options are:

Hiring temporary workers

Subcontracting a portion of production capacity

Temporary workers can be deployed rapidly with minimal onboarding time, allowing the firm to increase output without long-term labor commitments. This option is especially effective when the demand surge may be temporary or uncertain.

Subcontracting provides immediate access to external capacity without requiring capital investment. It allows the firm to meet demand while avoiding the risks associated with permanent expansion.

The other options are not viable in the short term:

Building new facilities is capital-intensive and slow

Hiring and training full-time employees requires time and long-term commitment

Operations Management distinguishes capacity-based options into short-term (temporary labor, overtime, subcontracting) and long-term (facilities, permanent workforce). In crisis situations, speed and flexibility dominate decision-making.

A key advantage of a periodic review inventory system is that all items are reviewed at the same time interval.

In a periodic review system:

Inventory levels are checked at fixed intervals (e.g., weekly, monthly)

Orders are placed to raise inventory to a target level

Multiple items can be ordered together

This approach simplifies administration and reduces ordering costs, making it especially suitable for:

Retail environments

Low-value or slow-moving items

Situations where continuous monitoring is impractical

The other options describe continuous review systems:

Individual item handling

Real-time inventory updates

Lower safety stock requirements

Operations Management recognizes periodic review as a trade-off between control and simplicity. While it may require higher safety stock, it offers operational efficiency and cost savings in many contexts.

Managers must consider control over internal operations and influence and leverage over suppliers to adapt effectively to changing business dynamics.

Internal operational control determines how quickly a firm can:

Adjust capacity

Improve quality

Reduce cost

Respond to demand changes

Supplier influence is equally critical in modern supply chains. Strong supplier relationships improve:

Reliability

Cost stability

Innovation

Responsiveness

Operations Management emphasizes that competitiveness increasingly depends on supply chain coordination, not isolated firm performance.

The other options are less relevant:

Firms rarely influence future legislation

Advertising costs relate to marketing strategy, not operational adaptability

Thus, effective supply chain management requires both internal excellence and external collaboration.
