Hypothesis-Driven Development

Hypothesis-Driven Development is a game that allows teams to reframe their user stories into testable hypotheses. By focusing on experimentation, participants learn to validate their ideas before developing features. This ensures better product-market fit and encourages a culture of continuous improvement.

Walkthrough

1. 1

   Introduction and Objectives

   10 min

   The facilitator explains the concept of Hypothesis-Driven Development and its importance for innovation. They present the workshop objectives: to transform user stories into testable hypotheses and validate ideas before development. Participants are invited to ask questions to clarify the process.

   Tip — Use concrete examples to illustrate the difference between a user story and a testable hypothesis.

2. 2

   Selection of User Stories

   15 min

   Participants, in teams, select several user stories they wish to work on. The facilitator encourages diversity in choices to explore different aspects of the product. Each team briefly presents their selected user stories to ensure a common understanding.

   Tip — Encourage teams to choose user stories that have a significant impact on the end user.

3. 3

   Transformation into Hypotheses

   20 min

   Each team reframes their user stories into testable hypotheses. The facilitator guides participants by explaining how to structure a hypothesis: 'We believe that [action] will lead to [result] for [user]'. Teams discuss and write their hypotheses on post-its.

   Tip — Remind teams to remain specific and measurable in formulating their hypotheses.

4. 4

   Testing Plan

   20 min

   Teams develop plans to test their hypotheses. The facilitator suggests common testing methods, such as A/B tests or user interviews. Participants must define success criteria for each hypothesis. Each team then shares their plans with the group for collective feedback.

   Tip — Suggest starting with simple and low-cost tests to quickly validate hypotheses.

5. 5

   Sharing and Adjustments

   15 min

   Teams present their hypotheses and testing plans to the rest of the group. The facilitator solicits constructive feedback and encourages adjustments if necessary. This step ensures that the hypotheses are clear and testable.

   Tip — Foster a supportive environment where feedback is seen as an opportunity for improvement.

6. 6

   Closure and Next Steps

   10 min

   The facilitator concludes the workshop by summarising the key learnings and discussing the next steps to integrate this approach into the development cycle. Participants are encouraged to apply this process to other projects.

   Tip — Suggest participants schedule a follow-up session to share the results of the tests conducted.

Variants

• Use hypotheses to explore entirely new product concepts.
• Introduce time constraints to simulate a rapid development environment.
• Dedicate a specific session to unvalidated hypotheses to understand the reasons.
