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
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.
06
Findings that arrive after the decision
Research timed to land after the investment committee has met is an audit, not an input. Work back from the decision date and cut scope rather than slip.

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.
