Today’s outcomes
- Explain segmentation variables in the context of customer analytics for product managers.
- Compare a product decision using the source outcome rather than intuition alone.
- Produce a reusable section of a segment opportunity map.

Core lesson
Make the choice inspectable
Segmentation variables matters when it changes a real allocation of attention, money, time, or delivery capacity. Segments are useful when they support differentiated action and economics.
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: Identify gaps in the market offering using perception and preference mapping methods.
What decision will segmentation variables improve, what evidence is sufficient for that decision, and what is the cost of being wrong?
Worked example
Segmentation variables in practice
For a loyalty programme for a grocery chain, the product manager must compare a choice about segmentation variables. 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 segmentation variables 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 segmentation variables?
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.
