Competitive response framework: what to do when a rival moves
Updated 3 min readBy the MECE Editorial Team
Short answer
A competitive response case asks how a company should react when a rival moves: a new entrant, a price cut or a new product. First understand the threat: which customers are affected, how much revenue is at risk and why customers might switch. Then compare responses such as matching, differentiating, focusing on a niche or holding steady.
Key takeaways
- Size the threat before choosing a response.
- Matching a price cut can cost more than the sales it protects.
- Predict the rival's next move: what are its incentives and constraints?
- Doing nothing is a valid option if the threat is small or self-limiting.
What is the competitive response framework?
How should the client respond to the rival?
Understand the move
- What exactly changed
- Which customers it targets
- Why they might switch
Size the threat
- Revenue and profit at risk
- How fast it could happen
Options
- Match
- Differentiate
- Focus on a niche
- Partner or acquire
- Hold steady
Choose
- Economics of each option
- Rival's likely counter-move
- Our capabilities
Worked example: a discount grocer opens near 10 stores
A fictional regional grocer with 50 stores learns that a discount chain is opening near 10 of them. Each affected store sells $30M a year at a 25% contribution margin. All numbers are illustrative.
- Revenue exposed: 10 stores × $30M = $300M
- Do nothing: lose 12% of sales = $36M × 25% margin = $9.0M of contribution lost
- Match prices on key items: costs 2% of $300M = $6.0M, and cuts the loss to 5% = $15M × 25% = $3.75M → total $9.75M
- Differentiate (fresh food, service, pickup): costs $2.0M, and cuts the loss to 8% = $24M × 25% = $6.0M → total $8.0M
Matching prices is the worst option here: it protects sales but gives away more margin than it saves. Differentiating costs least overall. Before deciding, check two things: whether customers in these neighborhoods really choose on price, and whether the discounter would cut prices further if matched.
Which competitive responses are there, and when does each work?
| Response | Works when | Main risk |
|---|---|---|
| Match (price or feature) | Customers choose mainly on that attribute and we have a cost advantage | Margin loss for everyone; a price war |
| Differentiate | Some customers value what the rival cannot easily copy: service, quality, convenience | Investment that customers do not value enough |
| Focus on a niche | The rival targets one segment and others stay loyal to us | Giving up volume that funds fixed costs |
| Partner or acquire | A capability gap would take too long to build | Price paid and integration |
| Hold steady | The threat is small, slow or likely to fail on its own | Underestimating a rival until it is too late |
What questions should you ask in a competitive response case?
- What exactly did the competitor do, and when?
- Which of our customers, products and locations overlap with the move?
- Why would customers switch: price, convenience, quality, novelty?
- What are the competitor's economics? Can it sustain the move?
- What have we already seen: early churn, price requests from customers?
How do you predict the competitor's next move?
Put yourself in the rival's position. What is its goal (share, profit, a foothold)? What are its costs and constraints? How would it react to each of your options? A simple payoff table, your options against its likely responses, often shows that the aggressive move invites a price war nobody wins.
What are the most common competitive response mistakes?
- Reacting before sizing how much business is actually at risk.
- Assuming the rival will not respond to your response.
- Matching by reflex, which often transfers margin to customers.
- Ignoring segments: the threat usually hits some customers far harder than others.

Frequently asked questions
Should a company match a competitor's price cut?
Only if the volume it protects is worth more than the margin it gives up, and customers really choose on price. Differentiating or focusing on less price-sensitive segments is often cheaper.
What is game theory in a case interview?
Thinking through how a rival will react to each of your options, often with a simple payoff table, so your choice holds up after their counter-move.
