Reader intent

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 shortlisting agencies

    What separates a capable market sizing & forecasting partner from a convincing proposal document.

  • First-time commissioners

    The questions that feel uncomfortable to ask, and the answers that should worry you.

  • Teams replacing an incumbent

    Where the last engagement went wrong is usually visible in how the next one is scoped.

01

1. Field coverage

Many agencies subcontract fieldwork outside the metros. Ask for a city-by-city list of supervised teams.

02

2. Quality control

Ask how interviews are verified.

  • GPS and time-stamping
  • Audio recording and back-checks
  • Data validation scripts
  • Supervisor accompaniment

03

3. Language capability

Questionnaires must be translated and back-translated, and moderators should be native speakers.

04

4. Industry experience

Ask for market sizing & forecasting examples from your category, such as FMCG, Healthcare, Pharmaceuticals, Banking & Financial Services.

05

5. Senior involvement

Find out who will write the report and present the findings. The best insight comes from experienced researchers.

06

Red flags

  • Quotes that are far below the market without explanation
  • No clear sampling plan
  • Unwillingness to share questionnaires or QC evidence
  • A one-size-fits-all report template

07

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

    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.

  • 06

    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.

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

    Write the recommendation first and check that the evidence supports it, not the other way round.

  7. 7

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