Growth strategy cases appear in approximately 20% of consulting interviews and test whether you can move beyond diagnosing problems to proactively identifying how a company should expand. Unlike profitability cases that focus on “what went wrong,” growth cases ask “what should we do next” — a fundamentally forward-looking challenge that requires both analytical rigor and creative thinking.
What Makes Growth Strategy Cases Different
Growth strategy cases are distinct from other case types because they are inherently open-ended. A profitability case has a clear problem (margins are declining) and a finite diagnostic tree. A growth case often starts with a healthy company that simply wants to grow faster — which means the candidate must generate options, evaluate trade-offs, and recommend a prioritized path forward.
Based on our analysis of growth strategy cases in the case library, the most common prompts fall into three categories:
| Prompt Type | Example | Frequency |
|---|---|---|
| Revenue growth target | “The client wants to double revenue in 5 years” | ~45% |
| Market share expansion | “How can our client grow from 15% to 25% market share?” | ~30% |
| Strategic direction | “The board wants a growth roadmap for the next 3 years” | ~25% |
Each prompt type requires a slightly different emphasis, but they all benefit from the same foundational framework.

The Ansoff Matrix is a 2x2 framework that maps growth options along two dimensions — products (existing vs. new) and markets (existing vs. new). It is the single most useful tool for generating a MECE set of growth options in an interview setting.
| Existing Products | New Products | |
|---|---|---|
| Existing Markets | Market Penetration | Product Development |
| New Markets | Market Development | Diversification |
Market Penetration (Low Risk, Incremental Growth)
Market penetration refers to growing revenue by selling more of your current products to your current customer base. This is typically the lowest-risk, fastest-to-implement growth lever. Tactics include:
- Pricing optimization: Adjusting price points to capture more volume or improve revenue per unit. In our experience, even a 3-5% price increase in a low-elasticity market can generate meaningful revenue uplift.
- Marketing and sales investment: Increasing share of voice, expanding the sales force, or improving conversion rates.
- Distribution expansion: Adding retail locations, e-commerce channels, or partnerships that reach existing customer segments more effectively.
- Customer retention: Reducing churn is mathematically equivalent to acquiring new customers. A 5-percentage-point improvement in retention often delivers more value than a 10% increase in acquisition spend.
Product Development (Medium Risk, Medium-Term)
Product development means creating new offerings for your existing customer base. This leverages the company’s existing customer relationships and distribution but requires investment in R&D or capabilities:
- Line extensions: New flavors, sizes, tiers, or configurations of existing products.
- Adjacent products: Offerings that serve the same customer need in a related way (e.g., a running shoe company launching athletic apparel).
- Bundling and cross-selling: Packaging existing products together to increase average revenue per customer.
Market Development (Medium Risk, Geographic or Segment Expansion)
Market development takes existing products into new markets — either new geographies or new customer segments. This is where market entry analysis becomes directly relevant:
- Geographic expansion: Entering new countries, regions, or cities. Consider market size, competitive dynamics, and regulatory complexity.
- New customer segments: Targeting a different demographic, industry vertical, or use case with the same core product.
- New channels: Selling through channels the company has not previously used (e.g., moving from B2B to B2C, or from retail to direct-to-consumer).
Diversification (High Risk, High Potential)
Diversification involves new products in new markets — the highest-risk quadrant. Companies typically pursue diversification only when core markets are mature or declining. In interviews, if the Ansoff analysis leads here, you should evaluate whether an acquisition is more appropriate than organic development, since building both new capabilities and new market knowledge simultaneously is extremely difficult.
Organic vs. Inorganic Growth
After identifying which Ansoff quadrant to pursue, the next question is how to execute. This decision — build, buy, or partner — often becomes the core analytical question in a growth case.
| Dimension | Organic (Build) | Inorganic (Buy/M&A) | Partnership/JV |
|---|---|---|---|
| Speed to market | Slow (12-36 months) | Fast (3-6 months post-close) | Medium (6-12 months) |
| Capital required | Lower upfront, higher ongoing | High upfront (acquisition premium) | Shared investment |
| Control | Full | Full (post-integration) | Shared |
| Risk profile | Lower financial, higher execution | Integration risk, overpayment risk | Alignment risk, IP leakage |
| Best when | Time is not critical, capabilities exist internally | Speed matters, target has key assets | Capabilities are complementary, neither party wants full commitment |
Based on our experience reviewing growth cases across industries, roughly 60% of interview growth cases involve an organic growth recommendation, 25% involve M&A or acquisition, and 15% involve some form of partnership. However, the strongest candidates always consider all three options before recommending one — interviewers want to see that you evaluated alternatives.
Structuring a Growth Case: Five-Step Approach
Step 1: Diagnose the Current Position (2-3 minutes)
Before generating growth options, understand where the company stands today. Key questions:
- What is the current revenue, growth rate, and market share?
- What is the competitive landscape — who are the top 3-5 competitors and how is share distributed?
- What are the company’s core capabilities and assets?
- Why is the company seeking growth now — is there a strategic catalyst (e.g., PE ownership with a 5-year exit timeline)?
Step 2: Map Growth Options Using the Ansoff Matrix (2 minutes)
Walk the interviewer through each quadrant, briefly assessing the opportunity in each. Not every quadrant will be relevant — the goal is to demonstrate structured thinking and then focus on the most promising 1-2 options.
Step 3: Size the Opportunity (3-5 minutes)
For each promising option, estimate the addressable market size and the client’s realistic capture rate. This is where market sizing techniques become essential. A rough estimate is sufficient — the interviewer cares more about your logic than your precision.
Step 4: Evaluate Feasibility and Trade-offs (2-3 minutes)
For each option, assess:
- Capabilities gap: What does the company need to build, buy, or borrow?
- Competitive response: How will incumbents react?
- Financial requirements: What investment is needed, and what is the expected ROI and payback period?
- Risk factors: What could go wrong, and how likely is it?
Step 5: Recommend and Prioritize (1-2 minutes)
Deliver a clear recommendation with a time-based prioritization:
- Quick wins (0-6 months): Market penetration tactics that require minimal investment — pricing optimization, sales force reallocation, marketing spend efficiency.
- Medium-term bets (6-18 months): Product development or geographic expansion that requires some investment and organizational effort.
- Long-term strategic moves (18-36+ months): Diversification, major acquisitions, or transformative market entries.
Common Mistakes in Growth Cases
- Defaulting to M&A without considering organic options first. Acquisitions are expensive and risky — always evaluate whether the company can grow organically before recommending a deal.
- Ignoring the client’s starting position. A company with 50% market share has very different growth options from one with 5%. Always anchor your analysis in the client’s current context.
- Generating options without evaluating them. Listing all four Ansoff quadrants is not a recommendation. You need to evaluate, compare, and prioritize.
- Forgetting implementation. A growth strategy without a timeline, resource plan, and risk mitigation is just a wish list.
Key Takeaways
- Growth strategy cases represent roughly 20% of consulting interviews and require a forward-looking, creative approach.
- The Ansoff Matrix (market penetration, product development, market development, diversification) provides a MECE starting framework for generating options.
- Always evaluate organic vs. inorganic vs. partnership execution modes — interviewers want to see that you considered alternatives.
- Size the opportunity before recommending it. A growth option that targets a $50M market is fundamentally different from one targeting a $5B market.
- Prioritize recommendations by time horizon — quick wins, medium-term bets, and long-term strategic moves.
- The strongest candidates link growth strategy to financial impact: revenue uplift, required investment, expected ROI, and payback period.
