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.

Fennie is independent and not affiliated with Western Governors University. This is an unofficial study guide.

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. 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. 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. 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. 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. 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.

How Fennie helps with C720

Daily Plans alternate C720's two demands — vocabulary mass and calculation practice — so neither crowds out the other. Fennie's flashcards hold the lean and quality terms, and chat walks EOQ and forecasting setups step by step when answers won't reconcile.

FAQ

Is WGU C720 hard?

Moderate-plus — the vocabulary volume is among the largest in the business core, and there's a real calculation layer. Spaced review plus a few reps of each problem type handles both.

How long does C720 take?

Typically 3–5 weeks. The lean and quality units carry the most recall weight.

Is there math on the C720 OA?

Some — EOQ, forecasting, and capacity-style calculations. It's a minority of questions but predictable in format, so practicing each type is cheap points.
