Software Architecture and Design moves from individual requirements to system-wide structure — selecting and implementing the design patterns that make large-scale software systems reliable and secure.
What D780 covers
The course covers designing, analyzing, and managing large-scale software systems, teaching various architecture types, how to select and implement appropriate design patterns, and how to build well-structured, reliable, and secure software systems.
The D780 performance assessment
Expect a performance assessment requiring you to select and justify an architecture type and design patterns for a given large-scale system, addressing reliability and security.
Key topics in D780
- Software architecture types
- Design pattern selection
- Building reliable, secure systems
Writing tips for D780
Follow the task instructions and rubric line by line
WGU performance assessments for D780 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 D780 assessment as a real deadline.

Why students seek help with D780
Students sometimes select a design pattern because it's familiar rather than because it genuinely fits the system's actual requirements — that justification is a core rubric expectation.
