Who this guide is for
Three readers arrive here with different problems. Each should be able to act on this page without reading all of it.
Buyers running a vendor call
Questions that reveal whether an agency has actually run market sizing & forecasting at your scale.
Procurement scoring proposals
A way to score the answers rather than the presentation.
First-time commissioners
What good answers sound like, so you can tell them from merely fluent ones.
01
The 10 questions
- Do you run fieldwork in-house in my cities?
- How do you verify interviews?
- How will you design the sample?
- Which languages do you work in?
- How do you handle translation?
- How is data secured, and are you DPDP compliant?
- Who leads the project day to day?
- Who writes the report?
- What exactly will I receive? (e.g. market model, five-year forecast, segment sizing)
- Can I see a sample report?

What goes wrong
Common mistakes in market sizing & forecasting
Most disappointing market sizing & forecasting studies fail for reasons that were visible in the design, not in the fieldwork. These are the ones we see most often, and what to do instead.
- 01
One source, multiplied
A single published figure extended by assumptions inherits every error in the original and adds new ones. Build two independent estimates and reconcile them.
- 02
Confusing the total market with the reachable one
TAM impresses investors and misleads planners. State SAM and SOM explicitly, with the constraints that separate them.
- 03
Assumptions nobody can trace
Any input without a visible source is challenged once and ignored thereafter. One assumption, one line, one source.
- 04
Borrowed growth rates
A CAGR copied from a published report is a guess with a decimal point. Derive growth from drivers you can observe — households, outlets, penetration, price.
- 05
Assumptions buried in the model
A number nobody can trace is challenged once and ignored thereafter. Every assumption on its own labelled line, with its source.
- 06
Analysis with no recommendation attached
Senior readers need a position. Close each section with what you would do, and what would have to be true for you to change your mind.
Run through this before sign-off
Your checklist before you brief anyone
A working sequence for a market sizing & forecasting project. Most of it costs nothing, and it saves the two weeks a re-field would take.
- 1
Build the estimate top-down and bottom-up independently, then explain the gap.
- 2
Validate with manufacturers, distributors or regulators who see actual volume.
- 3
Put every assumption on its own labelled line, with its source and date.
- 4
Separate TAM, SAM and SOM with the constraint that creates each step.
- 5
Scenario the three assumptions the answer is most sensitive to.
- 6
Hand over a working model rather than a PDF, so the team can update it next quarter.
- 7
Agree in writing who acts on each finding, and by when, before the debrief ends.
