C215: Operations Management

C215 Operations Management at Western Governors University looks at how operations and supply chains shape an organization's overall performance, from manufacturing to retail services.

WGU describes the course as focusing on the strategic importance of operations management to overall performance, emphasizing supply chain management principles relevant to business operations ranging from manufacturing goods to retail services. It covers the planning, control and decision-making tools and techniques of the operations function.

Many MBA students have never worked in operations, so the vocabulary can feel technical. The core skill is simple to state: diagnose where a process or supply chain is losing time, money or quality, and choose a tool that fixes it.

What C215 Covers

Key Concepts Explained

Economic Order Quantity

EOQ finds the order size that minimizes the combined cost of ordering and holding inventory: EOQ = square root of (2 x annual demand x order cost / holding cost per unit per year).

Bottlenecks and Capacity

A process can only move as fast as its slowest step. Increasing capacity elsewhere does nothing for output until the bottleneck is addressed, a core idea of the theory of constraints.

Lean and Waste

Lean thinking, drawn from the Toyota Production System, targets waste such as overproduction, waiting, unnecessary transport, excess inventory, extra motion, over-processing and defects. It applies to services as much as factories.

Supply Chain Principles

Supply chain questions often turn on trade-offs. Holding more inventory protects against disruption but ties up cash. Single sourcing can lower costs and deepen relationships but concentrates risk. Offshoring may cut unit costs while lengthening lead times.

The bullwhip effect, where small changes in customer demand grow into large swings further up the chain, explains why sharing demand information with suppliers matters. Good answers recommend specific practices, such as collaborative forecasting or dual sourcing for critical parts, and explain the cost of each.

Typical Assignments and How to Approach Them

Forecasting Basics

Most planning starts with a forecast. Simple methods include moving averages, weighted moving averages and exponential smoothing.

A three-month moving average of demand of 400, 440 and 480 units gives a forecast of 440 for next month; a trend is visible, so a method that captures trend would likely forecast higher. Always compare forecast with actual and track the error, since no forecast is exact.

Forecast error feeds directly into other decisions. Larger, less predictable errors usually justify more safety stock or more flexible capacity, both of which cost money, so improving the forecast can be one of the cheapest operations improvements available.

Where Students Get Stuck

• Improving the wrong step. Find the bottleneck before recommending capacity changes.
• Calculations without context. Explain what an EOQ or forecast means for the business.
• Ignoring strategy. Connect operations choices to how the firm competes.
• One-sided supply chain advice. Name the trade-offs of every recommendation.

Study Tips for C215

• Map a process you use every day, such as a coffee shop queue, and find its bottleneck.
• Practice EOQ and simple forecasting until the steps are routine.
• Follow a news story about a supply chain disruption and analyze it with course concepts.
• Keep a table of operations priorities and which strategies support each.

How We Help with C215

Send the task instructions, rubric, scenario and data, plus any evaluator comments. An operations tutor prepares a worked model, explains the tools, or reviews your analysis for accuracy and depth.
