Story mapping
Product Roadmap and Prioritisation · 45–60 minutes
Today’s outcomes
- Explain story mapping in the context of product roadmap and prioritisation.
- Design a product decision using the source outcome rather than intuition alone.
- Produce a reusable section of a prioritised outcome roadmap.

Core lesson
Make the choice inspectable
Story mapping matters when it changes a real allocation of attention, money, time, or delivery capacity. A roadmap communicates strategic intent and choices, not a promise of dates.
Start by naming the decision and the uncertainty around it. Separate evidence from assumptions, compare at least one alternative, and state what would make you revise the choice.
The source outcome for today is: Define story mapping and describe its process.
What decision will story mapping improve, what evidence is sufficient for that decision, and what is the cost of being wrong?
Worked example
Story mapping in practice
For a career-transition learning roadmap, the product manager must design a choice about story mapping. The team records the target user and outcome, the evidence currently available, the strongest alternative, and the next reversible test. The recommendation is written as a choice with a reason—not as a list of features.
Do the work · 20 minutes
Turn the idea into a decision
- Choose a product you know and write the specific decision that story mapping should support.
- List two pieces of evidence, two assumptions, and one credible alternative.
- Make a recommendation in three sentences and add one condition that would change it.

Knowledge check
Answer before opening
What is the decision at the centre of story mapping?
A good answer names an accountable choice, not merely an activity or output.
How should evidence and assumptions be separated?
Label observed facts, interpretations, and untested beliefs explicitly so the next learning step is visible.
What makes the recommendation revisable?
It includes a trigger, threshold, or new evidence that would justify changing course.
What should the portfolio artefact communicate?
The context, considered alternatives, chosen direction, rationale, evidence, and remaining risk.
