This lesson teaches how to segment customers in a way that helps solve a case rather than just describe the market.
Customer segmentation appears across:
Interviewers are not looking for random segment labels. They want segmentation that actually changes the strategy.
Useful segmentation groups customers in a way that matters for the decision.
Good segmentations often reflect differences in:
The goal is not to create many segments. The goal is to create actionable ones.
Use segmentation when the client needs to understand:
Ask:
Segment differently for:
Possible lenses:
For each segment, ask:
Do not treat every segment as equally valuable.
Prompt:
“A telecom operator has rising churn.”
A weak segmentation:
That may be relevant, but not necessarily strategic.
A stronger segmentation:
That is more actionable because the economic value and behavior are different.
A strong candidate:
A weaker candidate often:
If the segmentation does not change the answer, it is not useful.
Oversegmentation makes the analysis harder without adding much value.
Some segments matter far more than others.
A segment label is only the start of the analysis.
Take this prompt:
“A digital bank wants to grow revenue.”
Choose one useful customer segmentation lens and explain why it helps more than two weaker alternatives.
Since the question is revenue growth, I would segment customers based on both economics and behavior, for example high-balance primary-banking users, low-balance occasional users, and business customers. That matters more than a simple age split because it directly changes product strategy and monetization options.
