WGU D687 — COMPUTER SCIENCE
PROJECT DEVELOPMENT WITH A
TEAM
WGU’s current 2026 catalog lists D687 as “Computer Science Project Development with a
Team,” worth 3 competency units. (Western Governors University)

Because D687 is a project/performance-based course, rather than a conventional multiple-
choice certification exam, the questions below are original study questions designed around
the project-development, proposal, teamwork, peer-review, and feedback-analysis concepts
in your requested bundle. They are not reproduced WGU assessment questions, and I can’t
substantiate claims that they are “100% verified,” “actual exam questions,” or that completing
them guarantees a particular grade.

PRACTICE QUESTION BANK — QUESTIONS 1–100
INTRODUCTION

D687: Computer Science Project Development with a Team focuses on applying project-
development and collaborative problem-solving skills in a structured computer-science project
environment. The course requires students to translate a technical problem into a feasible project
proposal, collaborate effectively with team members, obtain and use peer feedback, and evaluate
the quality of the resulting work. WGU’s 2026 catalog identifies D687 as Computer Science
Project Development with a Team within the computer science curriculum. (Western Governors
University)

This practice bank is designed to strengthen higher-order reasoning rather than simple
memorization. The scenarios emphasize requirements analysis, project scope, technical
feasibility, stakeholder needs, risk management, communication, peer review, constructive
feedback, prioritization, documentation, and evidence-based improvement. Questions
deliberately present competing approaches so that learners must determine which action best
addresses the underlying project problem. The material can be used before beginning the project,
while developing the proposal, during collaborative work, or when analyzing peer-review results.
Students should still use their current WGU course materials and assessment instructions as the
authoritative source for submission requirements, because course requirements and evaluation
criteria can change.

QUESTIONS 1–100
Q1:

A student proposes a software solution because a department currently spends several hours each
week performing a repetitive manual process. During investigation, the student discovers that the
process is slow primarily because employees repeatedly enter incomplete information received
from another department. Which action would provide the strongest foundation for the project
proposal?

A) Begin selecting a programming language immediately
B) Investigate the upstream information problem and establish evidence for the actual root
cause
C) Create a prototype that automates the existing manua l process exactly as it currently operates
D) Ask users whether they prefer a web or mobile application

Rationale: The correct answer is B because a strong project begins with understanding the
underlying problem rather than prematurely choosing a technology. A is incorrect because
technology selection before problem validation can produce an inappropriate solution. C is
incorrect because automating a flawed process may preserve the underlying inefficiency. D is



2|P a g e

incorrect because platform preference does not establish the actual business or technical
problem.

Q2:

A proposed project claims it will “improve customer satisfaction.” The team has no baseline
satisfaction data and cannot identify which aspect of the customer experience is problematic.
What is the most important improvement to the proposal?

A) Increase the number of proposed software features
B) Define measurable evidence-based outcomes and identify how the current problem will
be measured
C) Replace the proposed technology with a newer technology
D) Reduce the project documentation

Rationale: The correct answer is B because measurable outcomes allow the team to determine
whether the proposed solution addresses the identified problem. A does not solve the
measurement problem. C assumes technology is the problem without evidence. D would make
the proposal less transparent rather than improving its validity.

Q3:

A stakeholder describes a project problem as “the application is too slow.” Performance
measurements show that response time is acceptable for most transactions but becomes excessive
when users submit reports containing thousands of records. What should the team investigate
first?

A) Replacing the entire application
B) Increasing the application's color contrast
C) Identifying the specific workload, processing path, and resource constraint causing the
performance degradation
D) Removing reporting functionality

Rationale: The correct answer is C because the evidence points to a workload-specific
performance bottleneck. A is unnecessarily broad. B is unrelated to the stated performance issue.
D eliminates functionality without determining whether the underlying problem can be solved
more appropriately.

Q4:

A project team identifies five stakeholder groups with different expectations. One group requests
extensive reporting capabilities, while another prioritizes simplicity. Which approach best
addresses this conflict during requirements analysis?

A) Implement every requested feature
B) Select the preference of the largest stakeholder group automatically

C) Identify stakeholder objectives, establish priorities, and document justified trade -offs
D) Ignore conflicting requirements until development begins

Rationale: The correct answer is C because requirements should be prioritized according to
project objectives, constraints, stakeholder value, and feasibility. A may create uncontrolled
scope. B assumes numerical stakeholder size determines priority. D postpones a critical decision
and increases implementation risk.

Q5:

A team identifies a problem but cannot determine whether it occurs frequently enough to justify
development effort. Which evidence would be most useful?

A) A team member's personal opinion
B) A list of competing technologies
C) Historical process data showing frequency, duration, cost, or impact of the problem
D) A screenshot of the current application

Rationale: The correct answer is C because objective historical evidence establishes the
magnitude and frequency of the problem. A is anecdotal. B addresses implementation rather
than need. D may document the current environment but does not demonstrate the problem's
significance.

Q6:

A proposed project would automate a process that currently takes employees 20 minutes per
transaction. However, the process occurs only twice per month. Which conclusion is most
defensible?

A) Automation is automatically justified because the process is inefficient
B) The team should compare the expected project cost and complexity with the actual
frequency and impact of the problem
C) Automation should automatically be rejected
D) The team should increase the estimated number of transactions

Rationale: The correct answer is B because feasibility depends on both problem impact and
solution cost. A ignores frequency. C assumes automation cannot be justified without
considering other benefits. D would manipulate the evidence rather than analyze it.

Q7:

During stakeholder interviews, users repeatedly describe a problem using different terminology.
What should the project team do?

A) Treat each term as a separate requirement
B) Choose the terminology used by the project manager
