"Assumption Mapping Fundamentals lets each team member reflect on any assumptions we may hold towards any topic relevant to our problem space."

- Jordan Ayenoue, Corporate Innovator, Orange Group

"The Assumptions Mapping Fundamental course is valuable to beginners and those who have experience with assumption mapping. I knew and practiced the process before, but I still learned a lot of helpful advice and tips, such as how to prevent and mitigate anti-patterns, the importance of a balance in participants, and what to do if there are assumptions that don't fit a particular box. Assumption mapping can be applied to all sorts of inputs at various levels, be it Vision and strategy, Plan, or a User journey map. Teams utilizing this tool will be well-equipped to separate what they wish was true from reality and move forward confidently."
