Case Interview Frameworks
Market Entry Framework
9 min read
Should our client enter this market? Market entry cases make up 15–20% of first-round cases at McKinsey, BCG, and Bain. The answer is almost never simply 'yes', it depends on market attractiveness, competitive barriers, your client's capabilities, and the economics of entry.
Always Start by Clarifying the Objective
Before building any framework, clarify what success looks like. Is the client trying to grow revenue, diversify risk, block a competitor, or deploy excess capital? The objective determines what you optimise for across every subsequent branch of the analysis.
The 5-Area Framework
- 1. Market attractiveness, size, growth rate, typical margins, regulatory environment, customer demand trends, and technology tailwinds/headwinds.
- 2. Competitive landscape, is the market fragmented or concentrated? Who are the major players? What are the barriers to entry: capital requirements, regulation, distribution lock-in, IP, switching costs, brand loyalty?
- 3. Company capabilities, does the client have the product, people, processes, and operating model to compete? What would need to be built or acquired?
- 4. Financial analysis, revenue potential at a realistic market-share assumption, fixed and variable entry costs, break-even timeline, sensitivity to key assumptions.
- 5. Entry mode, build (organic), partner / joint-venture, or acquire. Each has distinct speed, cost, control, and risk trade-offs.
Market Attractiveness in Depth
A large market is not automatically attractive. Probe margin structure: what do incumbent players actually earn? High revenue with thin margins is often a sign of intense competition or commoditisation. Also assess growth trajectory, a declining market with low barriers is a trap even if current size looks appealing.
Competitive Landscape in Depth
Map the market structure: concentrated (a few dominant players) vs. fragmented (many small ones). Concentrated markets usually have high barriers and established brands, harder to enter but potentially more stable once in. Fragmented markets are easier to enter but margins compress quickly as you grow.
- Barriers to entry: capital intensity, regulatory approval timelines, proprietary technology or IP, exclusive distribution agreements, network effects, customer switching costs
- Competitive response risk: will incumbents retaliate on price, increase marketing, or acquire your likely customers?

- Build organically: slowest to revenue but maximum control; best when the client has existing capabilities and no urgency.
- Partner / joint venture: faster, shared risk, access to local distribution, but divided control and potential IP leakage.
- Acquire: fastest path to market share and capabilities, but high upfront cost, integration risk, and cultural friction.
Delivering a Recommendation
Start with a direct yes or no, then support it with 2–3 key reasons. Address the primary risks and how the client can mitigate them. Close with concrete next steps (e.g. commission a customer survey, identify acquisition targets, pilot in one geography first).
A strong recommendation is conditional: 'Yes, we should enter, if we can secure distribution partnerships within 6 months and achieve 8% market share within 3 years to reach break-even.' Conditions make your answer defensible and show business judgment.
Do not treat market size as the only measure of attractiveness. Candidates who open with 'the market is $10B, so it's attractive' without examining margins, barriers, and competitive dynamics will be pushed back by experienced interviewers.
