WGU D471: GLOBAL SUPPLY CHAIN MANAGEMENT EXAM
QUESTIONS WITH VERIFIED SOLUTIONS - UPDATED
VERSION - COMPREHENSIVE REVIEW (2026/2027)
Q1: What is a supply chain?
ANSWER A supply chain is the network of all individuals, organisations,
resources, activities, and technology involved in the creation and sale of a
product, from the delivery of source materials from the supplier to the
manufacturer, through to its eventual delivery to the end user.
Q2: What is global supply chain management (GSCM)?
ANSWER Global supply chain management is the coordination and oversight
of supply chain activities across international borders, including planning,
sourcing, manufacturing, delivery, and returns, to create net value and
maximize competitive leverage.
Q3: What are the five primary components of supply chain management?
ANSWER The five primary components are: Plan (strategy and demand
planning), Source (procurement of goods and services), Make (manufacturing
and production), Deliver (logistics and distribution), and Return (reverse
logistics and handling returns).
Q4: What is the SCOR model?
ANSWER The Supply Chain Operations Reference (SCOR) model is a
process reference framework developed by the Supply Chain Council that
provides a standardised way to describe, measure, and improve supply chain
processes across the Plan, Source, Make, Deliver, Return, and Enable
processes.
Q5: What is the difference between upstream and downstream supply
chain?
ANSWER Upstream refers to the portion of the supply chain from raw
material suppliers to the manufacturer (inbound), while downstream refers to
activities from the manufacturer to the end customer (outbound), including
distribution, logistics, and retail.

,Q6: What is supply chain visibility?
ANSWER Supply chain visibility is the ability to track and monitor the
movement of products, components, and materials across the entire supply
chain in real time, enabling proactive management of disruptions, quality
issues, and delays.
Q7: What is a value chain?
ANSWER A value chain is a set of activities a company performs to deliver a
valuable product or service. It includes primary activities (inbound logistics,
operations, outbound logistics, marketing, and service) and support activities
(infrastructure, HR, technology, procurement).
Q8: What is the bullwhip effect?
ANSWER The bullwhip effect is a phenomenon where small fluctuations in
consumer demand cause increasingly larger fluctuations in orders upstream in
the supply chain, resulting in excess inventory, poor customer service, and
increased costs.
Q9: What causes the bullwhip effect?
ANSWER The bullwhip effect is caused by demand forecast updating, order
batching, price fluctuations, rationing and shortage gaming, and lack of real-
time information sharing among supply chain partners.
Q10: What is supply chain integration?
ANSWER Supply chain integration is the degree to which a firm collaborates
strategically with supply chain partners and manages intra- and inter-
organizational processes to achieve effective and efficient flows of products,
services, information, money, and decisions.
Section 2: Global Sourcing and Procurement
Q11: What is global sourcing?
ANSWER Global sourcing is a procurement strategy that involves identifying
and acquiring goods, materials, and services from suppliers located across
the world to take advantage of lower costs, quality, access to unique
capabilities, or favorable trade conditions.
Q12: What is the difference between purchasing and procurement?
ANSWER Purchasing is a transactional activity focused on buying goods and
services, while procurement is broader and encompasses strategic activities
including sourcing, supplier relationship management, contract negotiation,
and spend analysis.

,Q13: What is total cost of ownership (TCO)?
ANSWER Total cost of ownership is the sum of all costs associated with
acquiring, using, and maintaining a product over its life, including purchase
price, shipping, tariffs, quality costs, inventory carrying costs, and disposal
costs.
Q14: What is a make-or-buy decision?
ANSWER A make-or-buy decision is a strategic choice between producing a
product or component in-house versus outsourcing it to an external supplier,
based on factors like cost, core competency, capacity, quality, and risk.
Q15: What is offshoring?
ANSWER Offshoring is the practice of relocating business processes or
manufacturing to a foreign country to take advantage of lower labor costs, tax
benefits, or access to skilled talent, while maintaining company ownership.
Q16: What is nearshoring?
ANSWER Nearshoring is the transfer of business operations to a nearby
country, often sharing a border or in the same geographic region, to benefit
from lower costs while reducing the time-zone, cultural, and logistical
challenges of distant offshoring.
Q17: What is reshoring?
ANSWER Reshoring is the practice of bringing manufacturing or services
back to the home country from an overseas location, often driven by rising
offshore labor costs, quality concerns, supply chain risks, or political pressure.
Q18: What is a strategic supplier relationship?
ANSWER A strategic supplier relationship is a long-term, collaborative
partnership with a key supplier characterized by joint development, shared
risk, mutual investment, open communication, and aligned goals beyond a
transactional buy-sell dynamic.
Q19: What is supplier segmentation?
ANSWER Supplier segmentation is the process of categorizing suppliers
based on criteria such as spend volume, strategic importance, risk, and
market complexity (e.g., using the Kraljic Matrix) to apply differentiated
management strategies.
Q20: What is the Kraljic Matrix?
ANSWER The Kraljic Matrix is a supplier segmentation tool that plots supply
items on two axes — supply risk and profit impact — creating four quadrants:
WGU D471 Study Guide | Page 3 of 43
, leverage items, strategic items, bottleneck items, and non-critical items, each
requiring a different procurement strategy.
Q21: What is a request for proposal (RFP)?
ANSWER A request for proposal is a document an organization issues to
solicit bids from potential suppliers. It outlines project requirements, evaluation
criteria, timeline, and submission guidelines, allowing suppliers to propose
solutions and pricing.
Q22: What is spend analysis?
ANSWER Spend analysis is the process of collecting, cleansing, classifying,
and analyzing expenditure data to identify opportunities for cost reduction,
improve procurement decisions, and ensure compliance with procurement
policies.
Q23: What is category management in procurement?
ANSWER Category management is a strategic approach to procurement
where similar products and services are grouped into categories managed by
dedicated teams who develop deep market knowledge to optimize sourcing
and supplier relationships.
Q24: What is a preferred supplier list?
ANSWER A preferred supplier list is a vetted roster of suppliers that have
been evaluated and approved to provide goods or services to an organization,
often offering negotiated pricing, streamlined procurement, and assured
quality.
Q25: What are incoterms?
ANSWER Incoterms (International Commercial Terms) are standardized
trade terms published by the International Chamber of Commerce that define
the responsibilities of buyers and sellers for delivery, risk transfer, insurance,
and costs in international transactions.
Section 3: Logistics and Transportation
Q26: What is logistics?
ANSWER Logistics is the process of planning, implementing, and controlling
the efficient and effective forward and reverse flow and storage of goods,
services, and related information from point of origin to the point of
consumption.
Q27: What are the modes of transportation in supply chain?
