WGU D024 COMPREHENSIVE STUDY GUIDE
2026 FULL QUESTIONS AND SOLUTIONS
GRADED A+
◍ Vertical Integration.
Answer: Owning multiple assets in a supply chain.
◍ Control charts.
Answer: Graphical depictions of process output where the raw data is
plotted in real-time within upper (UCL) and lower control limits (LCL).
◍ Tangibles.
Answer: Appearance of physical facilities, equipment, personnel, and
communication materials, including access and effectiveness of
Internet-based information.
◍ Physical Development Barriers.
Answer: Motor delays, or difficulty hearing or seeing, physical conditions
such as nutrition, poverty, and homelessness.
◍ Peak Demand.
Answer: Demand which occurs in response to planned events such as
advertising, publicity or promotion. The release of a popular game
franchise's latest version often causes peak demand for a few days or weeks.
◍ Run charts.
Answer: Form of control chart plotted in real-time for processes that might
have common features, a common scale, or some form of central tendency
◍ Vygotsky's Theory of Cognitive Development.
Answer: Lev Vygotsky's sociocultural theory that emphasized the important
role of social interactions in the development of children's cognition.
,◍ Expressive Language Disorder.
Answer: Trouble getting message across when talking.
◍ Behaviorism Learning Theory.
Answer: How a student behaves is based on their interaction with their
environment.
◍ Accomodation.
Answer: Process of changing cognitive structures (schema) in order to
accept something from the environment. Can also develop new schemas.
◍ Articulation Difficulties.
Answer: Challenges in pronouncing words understandably.
◍ Just-in-time (JIT).
Answer: Manufacturing methodology aimed primarily at reducing flow
times within production systems as well as response times from suppliers
and to customers by receiving ordering and receiving inventory when ready
for use or just in time for use. Fundamental Concepts include: Allows
materials to flow in an assembly process similar to a continuous flow
process Uses general-purpose machinery Produces in small batches or small
lot sizes Uses a pull system Uses process facility layout Uses Kanban cards
Produces in smaller batches and shorter planning horizons ( 2-3 months
instead of 6-12)Simplifies the production process by: o Reducing set-up
times o Having workers in close proximity o Using total preventive
maintenance (preventing machinery breakdowns)
◍ Arnold Gesell.
Answer: First theorist to observe and document stages of physical
development.
◍ Chomsky's Theory of Language Development.
Answer: Chomsky's theory holds that children learn to use language because
of an innate capacity for language and communication; they do not need to
be explicitly taught but, rather, pick it up instinctively
,◍ Material Requirements Planning (MRP).
Answer: Acomputerized information system used for planning and
managing inventory for dependent demand items. Inputs include: Master
schedule file, Bill of materials file, Inventory file. Deals with getting the
right amount of raw material to the right place at the right time to support
production. Systematically designed to plan for production and deliver
product. MRP is widely considered to stop when materials are received
◍ Maslow's Transcendence Need.
Answer: Meeting spiritual needs or helping others achieve self-actualization.
◍ Six Sigma: Analyze.
Answer: Charts and diagrams are used to visualize the measurements and
the frequency of problems or defects, including scatter plots, pareto charts,
histograms, and run charts. The main objective of the _________ phase is to
determine the root causes of variation in the process that result in failures or
defects.
◍ MRP II - Manufacturing Resource Planning.
Answer: Often called manufacturing resource planning, builds on the
foundation of MRP. Also includes production planning, machine capacity
scheduling, demand forecasting and analysis and quality tracking tools into
the mix.Also features tools for tracking employee attendance, labor
contribution and productivity, project management, inventory management,
service and maintenance, and transportation
◍ Cooperative Learning.
Answer: Teacher led instruction that focuses on the product more than the
process.
◍ Aesthetics.
Answer: How a product looks, feels, sounds, tastes, or smells.
◍ Total Quality Management (TQM).
Answer: Pertains to: focus on the customer, quality function deployment,
responsibility for quality, team problem solving, employee training,
, fact-based management.
◍ Value Stream Mapping.
Answer: A Technique used to analyze the flow of materials, ideas, and
information to understand how processes function.
◍ Work-in-process (WIP).
Answer: These are partly finished parts, components, sub-assemblies, or
modules.
◍ Reverse Logistics.
Answer: Process of returning defective products to the manufacturer for
repair or replacement, and/or efforts to reuse and recycle materials.
◍ Forecasting.
Answer: Process of making predictions of the future based on past and
present data and most commonly by analysis of trends. Steps include: o
Determine the objectives of the forecast o Develop and test model o
Applying the model - Consider real-world constraints on the model's
application o Revising and evaluating the forecast
◍ Conventional Stage.
Answer: Moral development stage where your behavior is influenced by
peer pressure/society
◍ Variable costs.
Answer: Are those which change and can be adjusted as business conditions
change
◍ Kaizen Event.
Answer: An event to discuss process improvement opportunities using ideas
from the people who are directly involved in the processes
◍ Design capacity.
Answer: The maximum achievable output of a process or system.
◍ Crosby.
Answer: Used the phrase "Do it right the first time."Wrote a book in 1979
