The 3 Cs Framework: Company, Customer, Competitor
The 3 Cs framework breaks any business problem into Company, Customer, and Competitor. Here's how to use it in case interviews without missing a beat.
When a case prompt is broad and you have ten seconds to find structure, the 3 Cs framework is the fastest way to look organized and stay organized. It breaks almost any business problem into three lenses: Company, Customer, and Competitor.
This guide explains why three lenses beat a hundred random thoughts, how each C earns its place, and how to apply the framework in a case so you sound deliberate instead of frantic. By the end you will reach for the 3 Cs the moment a prompt feels too big to grab.
A business decision that ignores any one of the three Cs is a decision made half blind.
Why Three Lenses Beat a Hundred Thoughts
Imagine you are a doctor and a patient walks in feeling unwell. You do not run every test in the building at random. You check three things in order: the patient's own body and history, what the patient actually feels and needs, and what is going around the community right now. Skip any one and you misdiagnose.
The 3 Cs are those three checks for a business. Company is the patient's own body: your strengths, costs, capabilities, and financial health. Customer is what the patient feels and needs: who buys, why, and what they are willing to pay. Competitor is what is going around: who else is in the market and how they are moving.
Marketing professor Kenichi Ohmae built this triangle to force a complete diagnosis fast. Three lenses are enough to be thorough and few enough to remember under pressure. That balance is the whole point.
What Each C Actually Asks
Each lens has a sharp question you must answer, not a vague topic you list.
Company asks: what can we actually do? This is the internal scan: cost structure, brand, distribution, cash, and the capabilities you can lean on or that hold you back. A great product idea dies if the company cannot make or sell it profitably.
Customer asks: who needs this, and how badly? Segment the market, find what each segment values, and learn what they will pay. A business that cannot name its customer's real need is selling to no one in particular.
Competitor asks: who else is fighting for the same wallet? Map direct rivals and substitutes, then judge their strengths and likely reactions. The best move on paper fails if a competitor can copy it overnight or punish you for it.
Peloton in 2022 is a clinic in all three Cs going wrong at once. The company had ballooning costs and bloated inventory. The customer demand that the pandemic inflated had quietly evaporated. Competitors and cheaper substitutes crowded in while Peloton kept pricing like a luxury monopoly.

How to Use the 3 Cs in a Case
The 3 Cs work best for open prompts: market entry, new product launch, declining sales, or "should we do this?"
State the three lenses up front, then go deep on the one that matters most rather than spreading thin across all three. If a company is losing customers, lead with Customer. If a rival just slashed prices, lead with Competitor. Naming all three shows structure, choosing where to dig shows judgment.
Connect the lenses into a story, do not silo them. The insight usually lives between two Cs: "our customers value convenience, our competitor just made delivery free, and our company has no logistics network to match." That sentence diagnoses the whole problem in one breath, which is exactly what a partner wants to hear.

How to Practice the 3 Cs Before Your Interviews
Diagnose a real company. Pick a brand in the news and write three short answers: what can the Company do, what does the Customer need, what are Competitors doing. Then name the single tension that explains its current struggle. The tension is where the recommendation lives.
Lead with the right C. Take five different case prompts and decide which C you would open with for each. Practice justifying the choice in one sentence. This trains the judgment that separates a checklist from an analysis.
Connect two Cs out loud. For any business, force yourself to write one sentence that links exactly two of the three lenses into a single insight. The cross-lens insight is the part interviewers actually score.
The best way to practice the 3 Cs is under realistic pressure, with a case that fights back.
