What is assumption mapping? Complete guide with examples

Product managers play a crucial role in ensuring the success of initiatives by effectively identifying, prioritizing, and testing assumptions to de-risk products. Assumptions are foundational to any initiative, such as new features or marketing campaigns, and getting them right leads to successful outcomes, while overlooking them can result in failure. Product managers often focus too much on solutions rather than dissecting and testing the underlying assumptions, which can lead to unclear results when initiatives fail. To address this, tools like assumption maps are recommended for visualizing and evaluating assumptions based on their importance and the confidence in their validity. Testing assumptions through methods such as interviews, usability tests, market analysis, and building minimum viable products (MVPs) helps in reducing risks by validating ideas before significant resources are committed. Assumption maps should be treated as dynamic tools that evolve over time, reflecting changes in the product landscape and providing ongoing insights into where product managers should focus their learning efforts.
