Software Design and Quality Assurance applies a QA lens to every phase of software development. Testing, quality planning, and understanding how new code affects the bigger system.
What D480 covers
The course applies a QA focus to every phase of the software development life cycle, investigating best practices for quality analysis, quality planning, and testing strategies as they pertain to everyday software development.
Students learn how QA, testing, and code-writing practices interact within process models, the impact of new code on existing systems, and usability's role in application success. The course covers test plans, test cases, unit/integration/regression/usability tests, and testing tools.
The D480 performance assessment
Expect a performance assessment requiring you to develop a test plan (including unit, integration, and regression tests) for a given software system.
Key topics in D480
- Quality analysis and planning
- Test plans and test cases
- Unit, integration, and regression testing
- Usability testing
Writing tips for D480
Follow the task instructions and rubric line by line
WGU performance assessments for D480 are graded against a fixed rubric. Every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.
Show your actual code and test results, not just a description of what you built
WGU evaluators are trained to distinguish genuine software engineering work from a paraphrased summary. Include your actual code, along with evidence it was tested (test cases, output, screenshots). A rubric checking technical competency wants to see the working artifact and proof it functions.
Because WGU is self-paced, don't let "no deadline pressure" become no submission
There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school. A stalled task can quietly eat weeks of a term. Treat your own target date for each D480 assessment as a real deadline.

Why students seek help with D480
Students sometimes write only unit tests and skip integration/regression testing. A complete test plan addresses all the named testing types the course requires, not just the most familiar one.
