  • Faster time to market
  • Stronger investor confidence

02

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. 1

    Build the estimate top-down and bottom-up independently, then explain the gap.

  2. 2

    Validate with manufacturers, distributors or regulators who see actual volume.

  3. 3

    Put every assumption on its own labelled line, with its source and date.

  4. 4

    Separate TAM, SAM and SOM with the constraint that creates each step.

  5. 5

    Scenario the three assumptions the answer is most sensitive to.

  6. 6

    Hand over a working model rather than a PDF, so the team can update it next quarter.

  7. 7

    Agree in writing who acts on each finding, and by when, before the debrief ends.
