North Sun, a leading Japanese EV manufacturer with strong B2C presence, struggles with B2B market penetration despite operating in a rapidly growing market (27% CAGR). Candidates must identify root causes of low B2B market share, propose ideas to improve prospect-to-test-drive conversion rates, and determine the number of prospects needed to break even on a 1-day marketing event.

Key Insights:

  1. Revenue growth cases require analyzing market dynamics, client positioning, and conversion efficiency across sales funnel stages
  2. B2B sales challenges often stem from weak distribution channels, inadequate salesforce quality, poor pricing strategy, and limited marketing to corporate decision-makers
  3. Quantitative analysis combines customer economics (pricing, margins) with conversion metrics to determine business case viability
  4. Structured brainstorming with 7-8 ideas across logical categories (marketing, pricing, distribution, value proposition) demonstrates superior problem-solving
  5. Context and industry knowledge (e.g., charging infrastructure impact, fleet manager pain points) elevate analysis quality
