WGU C720: Operations and Supply Chain Management
C720 covers how organizations produce and deliver: process design, forecasting, inventory management, lean and quality methods, and supply chain coordination. It's a business-core course and ends in an OA with some calculation questions.

What makes it hard
The vocabulary is enormous: lean terms, quality tools, inventory models, and scheduling concepts pile up fast, and a calculation layer (EOQ, forecasting, takt-style problems) rides on top. Students who skip the math because it's a minority of questions leave easy points behind.
What you'll cover
- • Process and capacity design
- • Forecasting methods
- • Inventory management and EOQ
- • Lean operations and JIT
- • Quality management tools
- • Supply chain coordination
The C720 study guide
How to study for WGU C720, step by step.
- 1
Take the pre-assessment cold
The PA splits your gaps between the vocabulary mass and the calculation questions: two different study modes that need separate time.
- 2
Drill the lean and quality vocabulary daily
Lean terms, quality tools, and inventory concepts are the OA's recall bulk. Spaced flashcards from day one beat any late cram at this volume.
- 3
Practice each calculation type a handful of times
EOQ, basic forecasting, and capacity problems repeat in predictable formats. A few reps of each turns the math questions into free points.
- 4
Connect concepts to their purpose
For each tool (kanban, control charts, safety stock), know what problem it solves. Scenario questions ask which tool fits, not what the term means.
- 5
Retake the PA, then book the OA
Comfortable on both the vocabulary and the worked problems means ready. Most students land C720 in 3-5 weeks.

Is there math on the C720 OA?
