Triangulation Sizing Models

Category: Frameworks • Duration: 7 min • Difficulty: Intermediate

What You'll Learn

Recognize when to pivot between Top-Down and Bottom-Up sizing models.
Use independent variables to cross-verify and stress-test your calculations.
Isolate the structural driver that explains calculation variances.

Lesson Overview

Estimation is about precision and validation. Learn how to construct completely independent Top-Down and Bottom-Up models to cross-reference your findings and verify your strategic assumptions.

Your interviewer says: "The Swedish government wants to estimate the total annual market size for heavy-duty electric vehicle (EV) batteries in Scandinavia by 2030. They want an absolute gold-standard, bulletproof estimate. How would you structure this?"

Why This Matters for Consulting Interviews

MBB firms check if you can stress-test your own models and confidently explain why two different calculations might lead to divergent estimates.
