Growth Strategy Cases
This lesson teaches how to solve growth prompts using clear commercial levers.
Why This Matters
Growth cases are common because they test whether you can think beyond cost cutting and evaluate how a business can expand sustainably.
Interviewers use them to assess whether you can:
- break growth into logical levers
- distinguish market growth from share gain
- evaluate risk and feasibility
- recommend practical paths, not vague ambitions
The Case Pattern
Growth can come from:
- growing the overall market
- capturing more share in the current market
- expanding to new customers, products, channels, or geographies
A strong candidate separates those paths clearly and evaluates where the client has the best right to win.
What the Interviewer Is Testing
In a growth case, your job is usually to answer one of three questions:
- where should growth come from?
- how attractive is a specific growth path?
- what should the client prioritize first?
You need both a menu of options and a way to prioritize them.
How to Approach It
1. Clarify the growth objective
Confirm:
- revenue, profit, or market share goal
- time horizon
- whether the client wants organic growth, inorganic growth, or both
2. Split growth into major paths
Typical branches include:
- existing customers
- new customers
- existing products
- new products
- existing channels / geographies
- new channels / geographies
3. Assess attractiveness
For each path, consider:
- size
- growth rate
- margin potential
- ease of execution
4. Assess client fit
Ask:
- does the client have the capabilities?
- does the brand travel well?
- is the channel accessible?
- is there a clear differentiator?
5. Prioritize
Recommend the options with the best combination of:
Case Example
Prompt:
"A mature consumer brand wants to restart growth after several flat years."
A strong candidate might structure growth as:
- grow share in existing categories
- expand into adjacent products
- enter new channels such as e-commerce or specialty retail
- expand into new geographies
They would then compare those paths on market size, margin, capability fit, and execution risk rather than treating them as equal.
What Strong Candidates Do
A strong candidate:
- defines what kind of growth matters
- separates market growth from share gain
- distinguishes organic from inorganic options
- prioritizes the best paths instead of listing ideas endlessly
- ties growth to economics, not just topline ambition
What Weaker Candidates Tend to Do
A weaker candidate often:
- says "grow revenue" without specifying how
- brainstorms unstructured ideas
- ignores capability constraints
- recommends expansion everywhere at once
- forgets that some growth paths destroy value
Common Traps
Mistake 1: Treating all growth as good
Growth that erodes margin or distracts management may not be attractive.
Mistake 2: Ignoring the base business
Sometimes the best growth move is fixing retention, channel execution, or pricing before entering new spaces.
Mistake 3: Failing to prioritize
The interviewer wants to know where you would go first and why.
Practice Prompt
A bank wants to grow over the next three years. What are the main growth paths you would consider, and how would you decide which one to prioritize?
Example Approach
"I would first clarify whether the goal is revenue growth, profit growth, or market share, because that will affect the answer. Then I would structure growth into existing customers, new customers, new products, and new geographies or channels. For each path, I would evaluate market size, growth, profitability, and the client’s ability to compete. My initial hypothesis would be to prioritize the options that build on existing capabilities before moving to riskier adjacency plays."
What to Remember
- Growth cases require clear commercial logic, not generic brainstorming.
- Separate share gain, market growth, and expansion into new spaces.
- Evaluate both attractiveness and client fit.
- Prioritize the growth paths that are valuable and feasible.
