Chocolate Bar Game
Run the Chocolate Bar agile game to practise product ownership and iterative customer feedback. Rules, facilitation steps, debrief questions and variations.
Become a product owner and get feedback on your ultimate chocolate bar
The Chocolate Bar game is a short scrum simulation about product ownership. Teams design a chocolate bar their customers will love, gather feedback each round, and decide what to change next — feeling first-hand how iterative feedback shapes a product.
Learning goals
Product ownership, iterative feedback and customer value.
Time and format
About 60 minutes, in person or virtual.
What you need
3+ people and recycled or scrap paper.
How the game works
The goal is a scrum simulation where you create the chocolate bar that is most attractive to your customers within a set of constraints. Each phase pairs a short design round with a feedback round, so the team learns to listen, prioritise and improve rather than guess.
Agile Chocolate Bar game rules
- For each team there should be a designated Product Owner. In a small group, each person is their own product owner.
- Each phase has an iteration round (3 minutes) and a feedback round (1 minute).
- There are at least 3 phases.
How to facilitate
- Split into teams and choose a Product Owner for each (or have everyone own their own design).
- Run a 3-minute design round where the team builds or improves its chocolate bar.
- Run a 1-minute feedback round where customers respond to the design.
- Repeat for at least three phases.
- Have teams present their final designs for the group to critique.
Debrief questions
Run the debrief as a retrospective in TeamRetro so everyone can add their own perspective before you discuss as a group.
- How did you decide how to design your chocolate bar in each phase?
- How useful was the feedback from customers, and how did you improve the feedback you asked for each round?
- How did you measure the value of the chocolate bar to the customer each time to make improvements?
- If you didn’t measure customer value, why not?
- How did the feedback you received influence the design of the chocolate bar?
- What trade-offs did you have to make in the design?
- What proportion of the customers did you satisfy at the end?
- Would you have personally bought this chocolate bar?
- Were there any features that were added that did not come from customer feedback?
- Were any agile processes applied in the game, such as a backlog, dot voting or prototyping?
- What else did you learn from this activity that you wanted to share?
Variations
- Add a score from each customer each round on how likely they are to buy the chocolate bar.
- Allow or restrict who hears the feedback — for example, only the Product Owner attends the feedback sessions.
- Add constraints to the design, such as the materials or the size of the bar.
