Market entry is one of the two or three case types you are most likely to actually get, and it is really three questions stacked on top of each other: is this market worth being in, could this client win in it, and does the money work. This deck takes you from what the prompt is asking through the tools you need to answer it, market attractiveness, TAM, SAM and SOM, the entry modes from building to franchising, and how incumbents fight back when you show up. It leans on the sizing, profitability and strategy work you have already done, so you can spend your effort on the entry decision itself. By the end you should be able to take a cold prompt and land a real go or no-go.

What is a market-entry case, and what does your answer actually have to end in?
A market-entry case asks whether a client should go into a new market, and it ends in yes or no.
A market-entry case hands you a client and a market they are not in yet, a new country, a new customer segment, a new product category, and asks whether they should go in. It is one of the most common case types in consulting interviews because it forces you to do several things at once: size a market, judge the competition, and check whether the client could actually pull it off. What it is not is an essay. The interviewer wants to hear enter or don’t enter, plus the two or three reasons that drove it, said out loud in under a minute.
Card 2 of 16
Your interviewer opens with: Halden Dairy, a regional milk producer, is thinking about entering the plant-based drinks category. How would you structure this?
Three tests in order: is the market attractive, can we win in it, and is the prize worth it to us.
Lay out three buckets, in that order. First, is the market attractive: how big is it, how fast is it growing, and how profitable are the companies already in it. Second, can Halden win: does it have the brand, the plants, the shelf space and the cost position to take share from people who got there first. Third, is it worth it: what does entry cost, what does it return, and is that better than anything else Halden could do with the same money. Say all three out loud before you dig into any one of them.
Card 3 of 16
What makes a market attractive to enter, beyond simply being big?
Attractiveness is size, growth, profitability, and how concentrated the competition already is.
Size tells you the ceiling, but a large market that is barely growing and already carved up between three players earning thin margins is a bad place to arrive. Growth matters because in a fast-growing market you can win volume without taking it off anyone, which incumbents fight far less hard. Profitability, meaning the margin the existing players actually earn, tells you whether the economics survive the trip. Concentration, meaning how much share sits with the top few, tells you how much of the market is genuinely available. A market can pass on size and fail on the other three.
Card 4 of 16
An interviewer stops you and asks for the size of the prize for Verrow Fitness in TAM, SAM and SOM terms. What are those three, in plain language?
TAM is everyone, SAM is everyone you could serve, SOM is the slice you could realistically win.
TAM, the total addressable market, is every dollar spent on the thing anywhere, with no constraints at all. SAM, the serviceable addressable market, narrows that to the part Verrow could actually reach given its product, its channels and the places it operates. SOM, the serviceable obtainable market, narrows again to what it could plausibly capture within a few years against competitors already sitting there. If the category is $4 billion, Verrow only sells in regions worth $900 million, and 8 percent share there is credible, the number that belongs in your recommendation is about $70 million, not $4 billion.
Card 5 of 16
Your engagement manager agrees the market looks great, then asks the harder question: does the client have a right to win here? What does that mean, and how do you test it?
A right to win is a specific reason this client beats incumbents, not just a wish to be in the market.
A right to win is a concrete answer to why this client, rather than anyone else with money, takes share in a market where competitors are already established and already know the customers. You test it by listing what the market actually rewards, low cost, a trusted brand, distribution reach, technical skill, then checking honestly which of those the client already owns and which it would have to buy or build from scratch. Enthusiasm is not a capability. If every advantage on the list has to be acquired, the client is just another new entrant, and interviewers listen closely for whether you will say that.
Card 6 of 16
Calder Foods has decided the market is worth entering. What are its options for how to actually get in, and what is the trade-off between them?
Build, acquire, joint venture, license or franchise, trading speed and cost against control.
Building organically means starting from nothing, the slowest and most capital-hungry route up front, but you keep all the economics and all the control. Acquiring buys a business that already works, so you arrive with customers and staff on day one, at a price. A joint venture pairs you with a local partner who brings market knowledge or distribution and takes a share of both the profits and the decisions. Licensing and franchising let someone else run the operation using your brand or technology for a fee, the fastest and cheapest way in and the one where you control quality least.
Card 7 of 16
Northbay Logistics could build a warehouse network in the new region or buy a mid-size local operator. Why is buying faster, and why does it almost always cost more?
Buying skips the ramp-up years, and the seller charges you for the profits you skipped.
Building means years of losing money while you sign customers, hire people and grind toward the scale where the unit economics finally work. Buying hands you all of that on closing day, which is precisely the point. The price reflects it, because you are paying the seller today for the future profits of a business that already runs, plus a premium to persuade them to give up control, so the cheaper-looking build wins on price and loses on time. Which one is right depends on how fast the window is closing, and a good answer says so rather than picking a side on instinct.
Card 8 of 16
You already know barriers to entry as the thing that protects incumbents. On a live case you are the one standing outside. What do those barriers actually cost you?
From the outside, barriers are the bill you pay before your first profitable unit.
Capital requirements mean a plant, a fleet or a licence you have to fund before a single sale. Scale economies mean the incumbents’ cost per unit is already lower than yours will be for years, so you either lose money or price above them. Switching costs, whether contracts, habits or integration work, mean even a genuinely better product moves slowly. Regulation and locked-up distribution can simply shut the door. Adding all of that up gives you the real cost of entry, and that number, rather than the market size, is what usually kills a case.
Card 9 of 16
You have built a model showing Ferrow Retail at 6 percent share in three years. Your partner asks what the incumbents are doing while that happens. Why does that question matter so much?
Incumbents fight back, so a plan that assumes they stand still is not a plan.
Share does not sit unclaimed, it gets taken from someone, and that someone can cut price, tie customers into longer contracts, flood the channel with promotions, or simply copy whatever you launched with. The usual pattern is that the strongest incumbent defends hardest in the segment where it earns the most. So build the response into the case: assume price falls a few points, ask whether your economics still hold at that price, and check who can afford a long fight. A recommendation that survives the counterattack is the only one worth giving.
Card 10 of 16
Halden Dairy wants to enter a country where it has never operated. Beyond the numbers, what non-financial barriers should you raise, and how do you keep that from sounding like hand-waving?
Rules and local habits change your cost, product and timeline, so price them rather than just naming them.
Regulation shows up as licences, ownership limits that force you into a local partner, labelling and safety standards, tariffs and data rules, each of which is a delay and a cost you can put a number on. Culture shows up as different tastes, different buying occasions, different retail channels, and a workforce that expects to be managed differently. The way to stay credible is to convert all of it into figures, so a licence that takes nine months means revenue starts in year two, and reformulating for local taste adds four points to cost. Vague respect-the-culture comments land badly, quantified ones land well.
Card 11 of 16
Your client is already in its market and simply wants to grow. What is the full menu of growth levers, and how do you make sure you have not missed one?
Grow by winning more customers, more per customer, more often, new products, or new markets.
Revenue is customers times what each one spends times how often they buy, so the first three levers fall straight out of that arithmetic: win more customers, get more out of each purchase through price or basket size, or get people buying more often. Beyond the existing business there are two more, selling new products to the customers you already have, and selling what you already make in new markets, which is exactly where market entry sits. Running the whole list out loud before you pick one is how you show an interviewer you are being exhaustive rather than lucky.
Card 12 of 16
A chief executive tells you she wants to double revenue in four years and asks whether to grow it herself or go and buy it. How do you frame organic versus inorganic growth?
Organic growth is cheaper but capped by your own capability, acquisition is the reverse.
Organic growth means growing out of your own operations, more stores, more products, more customers, funded by your own cash and limited by how fast your own capability can expand. Inorganic growth means acquiring it, which delivers revenue immediately but costs a premium and leaves you with an integration job, which is where most of the promised value quietly disappears. The honest framing is that organic growth is limited by what you can build, while acquisition is limited by what happens to be for sale and what you can afford. Four years is short enough that most doubling plans need both, and saying so beats picking one.
Card 13 of 16
The client is nervous about committing $200 million to a full launch, so you suggest piloting first. What should that pilot actually be designed to test?
A pilot exists to test the assumption that would break the case, not to prove the plan works.
A pilot is only worth running if it can change the decision, so pick the one or two assumptions the whole business case rests on and design around those. Usually that means customer take-up at the price you assumed and the true cost to serve once you are actually operating, not brand awareness. Set the number that means go and the number that means stop before you start, or the results become something everyone reads their own way. And run it somewhere representative, because a pilot in your friendliest city tells you almost nothing about the rest of the market.
Card 14 of 16
The client is going to spend real money on the back of your work. What does a defensible market-entry business case actually contain?
Revenue at a realistic share, cost to serve it, the one-off cost of entering, and when it pays back.
Start with revenue built from the bottom up, your realistic share of the serviceable market at a price you can defend, not a share pulled out of the air. Take off the cost to serve that revenue, then the fixed cost of running in the market, then the one-off cost of getting in at all, the plant, the licences, the hiring, the losses of the early years. What falls out is a cash path over five years, and the number people argue about is the payback period, the year cumulative cash finally turns positive. Then flex the two assumptions you trust least and show whether the answer still holds.
Card 15 of 16
Halfway through the case the numbers stop supporting entry, and your interviewer is clearly enjoying the market. How do you say don’t enter without sounding like you gave up?
Say no by naming the number that fails and the condition that would change your mind.
Recommend against entry exactly the way you would recommend for it, answer first, reasons behind it. Point at the specific thing that fails, that payback runs past eight years, that the client has no route onto the shelf, that the incumbent can undercut you at will, rather than saying the market looks hard. Then give the client somewhere to go: what would have to be true for the answer to flip, and what a better use of the same money looks like. Interviewers set this trap deliberately, because a candidate who cannot say no cannot be trusted when they say yes.
Card 16 of 16
Last question. Verrow Fitness can enter a $900 million market where the top two hold 70 percent, needs $120 million up front, and models 5 percent share by year four. Go or no go?
Commit to an answer, support it with the economics, and name the one risk that would break it.
Do the arithmetic out loud: 5 percent of $900 million is $45 million of revenue, and at a plausible 15 percent margin that is under $7 million of profit a year against $120 million spent, so payback runs past a decade. On those numbers the answer is no, because a 5 percent share in a market where two players hold 70 percent is both small and expensive to defend. Then name the risk in your own answer, that share and margin are assumptions rather than facts, and say what would flip it, entry by acquisition or a niche the incumbents ignore.
