Let’s get started.

What is the Beer Game?

The beer game, also known as the beer distribution game, or supply chain management beer game, is a role-playing simulation that illustrates the complexities, challenges, and nuances of managing a supply chain.

Originally developed at the MIT Sloan School of Management in the 1960s, it has stood the test of time, helping countless students, professionals, and organizations grasp the fundamentals of supply chain dynamics — most notably the bullwhip effect.

The simulation is centered on a multi-tiered supply chain scenario of retailer, wholesaler, distributor, and factory. The simplicity of managing just one product—beer—masks underlying complexities like the bullwhip effect and the importance of timely information sharing.

While the premise seems straightforward, the underlying theory reveals how small fluctuations in demand can cause increasingly larger swings in inventory and orders upstream in the supply chain.

The game, therefore, acts as a springboard for discussions about communication, coordination, and strategic decision-making, showcasing how information delays and siloed thinking can lead to inefficiencies and costly mistakes.

History of the Beer Game

The MIT beer distribution game originated as a classroom exercise at the Massachusetts Institute of Technology in the early 1960s. Created by Jay Forrester and his colleagues, the game quickly spread to universities and training programs worldwide.

Over the decades, it has evolved from a simple board-based activity into more sophisticated forms, including beer game simulations online. Today, online beer games and digital platforms—such as those offered by Zensimu—allow for global participation, real-time data analytics, and the opportunity to run multiple iterations rapidly.

What is the Objective of the Beer Game?

The fundamental objective of the beer simulation game is to minimize total supply chain costs—often represented by inventory holding and backorder costs—by managing orders effectively. Each player aims to balance the often-competing priorities of having enough stock to meet demand without holding excessive, costly inventory.

By the end of a beer distribution game simulation, participants learn that achieving optimal supply chain performance is not about local optimization but about cohesive, system-wide strategy.

Who Can Benefit from the Beer Game?

The beer game supply chain simulation benefits a wide array of participants and settings, as illustrated by various real-world examples:

• Business Professionals: Managers, supply chain planners, and procurement specialists use the beer distribution game in team-building activities, onboarding programs, and strategy sessions to illustrate demand fluctuations, inventory management, and communication challenges. Bose leveraged the Beer Game during its online sales seminar to gain critical insights and improve their supply chain operations.
• Consultants and Agencies: Consulting firms integrate the beer game solution into workshops, and corporate training events to demonstrate the impact of different policies and strategies on supply chain performance for their clients. The Mews Partners case study showcases how a consulting firm effectively utilized the Beer Game to optimize their training sessions and deliver measurable value to clients.
• Students and Educators: Universities and business schools employ the MIT beer game as a practical teaching tool, including live classroom simulations, online sessions, and academic workshops, to illustrate core supply chain concepts and improve students’ decision-making skills. The Bocconi case study highlights how an academic institution successfully integrated the Beer Game in a large online contests to enhance learning outcomes and student engagement.

Long-Term Benefits of the Beer Game

The lessons learned from the Beer Game go far beyond the immediate experience:

1. Cost Reduction: Participants learn to balance inventory levels, minimizing excess costs due to stockouts or overages.
2. Improved Information Flows: The simulation highlights the importance of quick and accurate communication across the supply chain.
3. Adoption of Systems Thinking: Players understand that local decisions impact the entire system.
4. Enhanced Resilience: Simulated scenarios prepare teams to better respond to real-world disruptions.

3 Learnings of the Beer Game

By immersing players in realistic scenarios, the Beer Game highlights key challenges like the bullwhip effect, the importance of information flow, and the impact of lead times. Below, we present five essential lessons that consistently emerge from the Beer Game experience.

The Bullwhip Effect

The bullwhip effect is a classic phenomenon in supply chain management, prominently showcased within the Beer Game. It occurs when even minor fluctuations in customer demand at the retail level grow disproportionately larger as you move upstream through the wholesaler, distributor, and ultimately the factory. Initially insignificant changes can escalate into significant order volatility, causing overstocking, stockouts, and increased operational costs.

Within the Beer Game setting, players quickly see how a small miscalculation or delay in information flows can create outsized, 'whip-like' swings in inventory and orders. Rather than serving as a simple exercise, this dynamic simulation demonstrates the critical importance of clear communication, stable ordering policies, and system-wide thinking.

For a deeper understanding, you can visit Zensimu’s bullwhip effect guide.

Lead Times and their impact

In the Beer Game, lead time refers to the delay between when an order is placed and when it is fulfilled. This includes the time it takes for the supplier to process the order, pack the goods, and ship them, as well as the transit time until the product arrives at your location.

The Beer Game effectively demonstrates how these time delays affect inventory levels, order quantities, and overall decision-making.

When players face longer lead times, they must forecast demand further into the future. A misalignment between current demand signals and projected needs can easily result in over-ordering or under-ordering. This, in turn, contributes to the bullwhip effect—small fluctuations in demand become amplified due to the lag in receiving new inventory. Longer lead times generally increase uncertainty, making it harder to accurately judge how much to order at any given time, especially if demand patterns are volatile or if communication within the supply chain is limited.

By exploring different scenarios within the Beer Game, participants gain firsthand insight into how changing lead times can influence their strategies and outcomes. They quickly learn that reducing lead times, or at least better understanding and managing them, can stabilize the supply chain.

Importance of Collaboration and Communication

In any supply chain, timely and accurate information flow is crucial for making informed decisions. The Beer Game highlights how even small delays or inaccuracies in communicating demand, inventory levels, or shipment statuses can lead to misalignment and costly inefficiencies.

When one player in the chain receives outdated or incomplete information, they are more likely to overestimate shortages or surpluses. This reactive behavior often results in larger order fluctuations, higher inventory carrying costs, or stockouts—all manifestations of the bullwhip effect.

Zensimu emphasizes the value of teamwork and transparent communication within supply chains through several key features:

• Transparent Mode: Participants can see each other’s inventory and production plans, mimicking a shared ERP system and encouraging more informed decision-making.
• Real-Time Chat: Teams communicate instantly, discussing strategies, negotiating adjustments, and coordinating responses as situations evolve.
• Automated Alerts: Players receive immediate notifications about stock shortages or backorders, prompting collective action to reduce costly delays.

Improving information flow involves not only faster communication but also clearer, more consistent data sharing. For instance, the concept of Just-In-Time (JIT) manufacturing emphasizes maintaining minimal inventory and responding quickly to actual demand signals rather than forecasts. JIT relies heavily on accurate and immediate information so that production aligns closely with consumption, reducing waste and excess holding costs.

It provides additional perspectives, strategies, and best practices that will help deepen your understanding and improve your overall supply chain management approach.

With these key lessons in mind, let’s now turn our attention to the practical side of things and explore How Does the Beer Game Simulation Work? This will help you understand the step-by-step process of playing the game and applying these insights in a hands-on environment.

How Does the Beer Game Simulation Work?

How to Play the Beer Game

In the classic beer game, four roles represent tiers of the supply chain:

• Retailer: Directly faces customer demand.
• Wholesaler: Buys from the distributor and sells to the retailer.
• Distributor: Purchases from the factory and distributes to wholesaler.
• Factory: Produces beer and supplies the distributor.

To get a clearer picture of the Beer Game in action and better understand the sequence of decisions and reactions throughout each round, our tutorial video walks you through the game’s mechanics step-by-step, helping both newcomers and experienced professionals understand the rules and refine their strategies.

Players receive weekly orders and must decide how much to order from their immediate upstream supplier.

Each stage:

• Has its own stock of beer cases,
• Has a supplier from which it receives beer cases - and to which it places orders,
• Has a client from which it receives orders (= demand) - and to which it ships beer cases
• The Retailer's client is the end-consumer, played automatically by the computer. The manufacturer doesn't have a supplier but produces beer cases internally.

Their choices affect inventory levels, backlogs, and costs. The winner is the team or individual that achieves the lowest cumulative cost. Here is an example of a Beer Game session Results Page:

Debriefing After the Game

Once the simulation is complete, a debriefing session is held to analyze performance and draw lessons learned. Participants review the overall results, including:

• The total costs of the supply chain.
• Fluctuations in inventory and orders.
• The causes of inefficiencies, such as the bullwhip effect or communication delays.

How Do You Play the Beer Game in Class?

When played in a classroom setting, the beer game simulation often begins with a brief introduction from the instructor, followed by assigning roles and distributing materials such as game boards, tokens (representing beer cases), and record sheets.

Students rotate turns, placing orders and receiving shipments. The instructor tracks costs and leads a debrief session afterward, highlighting key insights about supply chain management and decision-making.

How Do You Win the Beer Simulation Game?

Winning strategies usually involve:

• Stabilizing Orders: Avoid overreacting to short-term demand fluctuations.
• Better Communication: Share demand and inventory data transparently.
• Consistent Policies: Adhere to a sound ordering strategy that factors in lead times and avoids panic adjustments.
• Focus on the Big Picture: Resist the temptation to prioritize local optimization. Instead, consider the health of the entire supply chain.

Players assume roles in a supply chain and make ordering decisions weekly.

Board Beer Game vs. Online Beer Game

The traditional board beer game uses physical tokens, cards, and boards. It’s tactile and interactive, often played in person. However, a beer distribution game online offers several advantages:

• Real-Time Analytics: Online versions track inventories, orders, and costs automatically, providing instant feedback.
• Scalability: Host large groups and remote participants easily.
• Accessibility: No need for physical materials. Participants can join from anywhere worldwide.
• Speed and Iterations: Faster setup times and the ability to run multiple simulations improve learning outcomes.

We’ve created a comprehensive comparison article who’ll show you the differences between the traditional, physical board setup of the Beer Game and its modern online counterparts.

Zensimu's hybrid Beer Game Simulation combines the strengths of both formats, providing a comprehensive solution that maximizes engagement, efficiency, and adaptability.

By examining each format’s strengths and limitations, you’ll be able to determine which approach best fits their teaching or training objectives.

What are the Materials needed for the Beer Game Supply Chain?

For the board version, you typically need:

• A game board or printed layout representing each tier.
• Tokens or chips to represent beer inventory.
• Order slips or cards for placing orders.
• Record sheets (or individual computers with Excel spreadsheets) to track inventory, orders, and costs.

Online beer simulation games eliminate these physical needs, replacing them with digital interfaces and dashboards.
