An original hypothesis map
Copy and edit every field for your context
| Layer | Hypothesis | Test and evidence | Owner / decision |
|---|---|---|---|
| Business | Unassigned jobs create costly manual follow-up | Observe a dispatch window and record actual handling | Operations / quantify the problem |
| User | A priority queue helps dispatchers find urgent jobs | Task test with a simple prototype | Product / revise or keep the flow |
| Technical | The current system exposes assignment events | Review API docs and a nonproduction sample | Engineering / integration or fallback |
| Risk | The queue reveals only authorized accounts | Attempt cross-account access and export | Security owner / release gate |
Map dependencies rather than features
Draw the reasoning in words: if job events are not available, the queue cannot be current; if the queue is not current, the task test may validate a misleading interaction. That makes integration feasibility a prerequisite rather than an implementation detail discovered after design.
Separate observed facts from interpretations. “Three participants missed the status label” is an observation; “all dispatchers need a dashboard” is an inference that needs more evidence. Keep the source and date of observations in your internal map without publishing private participant details.
A repeatable stakeholder review
Ask operations to challenge the problem and exception cases.
Ask users to demonstrate the current workaround.
Ask engineering to identify dependencies and unknown data contracts.
Ask the data owner to review permissions and retention.
Choose the next smallest test and give its decision an owner.
Update the map after evidence
Keep the old hypothesis and record whether the result supported, contradicted or failed to resolve it. A failed test can still be useful if it changes the next decision. If stakeholders disagree, identify the observation that would distinguish their explanations rather than averaging incompatible opinions.
Use the map to constrain the first-release brief. A proposed feature should trace to a tested need or an explicitly accepted risk. This keeps the map useful as the product changes instead of turning it into a decorative diagram.
Frequently asked questions
Is a hypothesis map a feature roadmap?
No. It records uncertainty and evidence. A roadmap describes intended work and should follow the decisions the map supports.
How detailed should the map be?
Detailed enough to choose the next test and owner. Split broad claims when they require different evidence.
