Part 1 of 9

What is a new product launch case?

A new product launch case asks whether a company should introduce a new product, and if so, how to price, sell, and market it. The product is new, but the market may not be. A company adding a flavor to a category it already sells in is a launch case, not an entry case.

These cases combine several skills. You will size demand, check the competition, and work out whether the product makes money, often by calculating a breakeven point. Pricing questions come up often, so the pricing lesson pairs well with this one.

The skill being tested

Interviewers want to see that you can separate a good product from a good business. Plenty of great products lose money. The question is whether this one will sell enough, at a high enough margin, without stealing sales from the company's other products.

How to spot a new product launch case

These prompts name a product the company is considering. Listen for phrases like these:

  • Our client is considering launching a new product line
  • Should we introduce a lower-priced version?
  • We've developed a new drug. How should we launch it?
  • Should we add a premium tier?
  • R&D has a prototype ready
  • Is this product worth bringing to market?

If the company would be selling in a market it has never served, it is closer to a market entry case. Not sure which type a prompt is? The first lesson covers how to identify the case type.

The new product launch framework

Four questions. The first three decide whether to launch. The fourth decides how.

End with a decision

  • Launch
  • Don't launch
  • Test first
A test launch in one region or channel is often the smartest answer when the numbers are close.

Will customers buy it?

Who is the product for, what problem does it solve, and how many of those customers exist? Then ask how it compares with what they use today. A product that is only slightly better than the alternatives rarely gets people to switch.

Will it make money?

Estimate the price, the cost per unit, and the fixed costs to launch it, like marketing, tooling, and retailer fees. Then work out the breakeven volume and ask whether the company can realistically sell that much.

The two numbers to always check

Breakeven volume is fixed costs divided by profit per unit. It tells you how many units the product has to sell before it makes a dollar. Cannibalization is the share of new sales that would have gone to the company's existing products anyway. Those sales are not new revenue, and they can turn a profitable launch into a loss.

Put breakeven in everyday terms

"4 million units a year" is hard to judge. "8 units per store per week" is easy to compare with what similar products sell. Break big numbers down until you can sanity check them.

Want to see how this structure compares to the others? The frameworks guide covers them side by side.

How to solve it, step by step

  1. Clarify the objective

    Ask why the company wants to launch this product and what success looks like: revenue, profit, market share, or defending against a competitor.

  2. Understand the customer

    Identify who would buy it, what need it meets, and how big that group is.

  3. Check the product and competition

    Compare the product with the alternatives customers use today, and ask how competitors would respond.

  4. Test the economics

    Estimate price, costs, breakeven volume, and cannibalization of existing products.

  5. Decide and plan the launch

    Recommend launch, no launch, or a test, and lay out the channels, marketing, and timing.

Worked example: FreshNest breakfast bowls

Try each question on your own before you reveal the answer. Say it out loud if you can, the way you would in an interview.

Case prompt

Your client is FreshNest, a US maker of premium frozen meals sold in grocery stores. It already sells frozen breakfast sandwiches and is considering launching a line of frozen breakfast bowls. Should FreshNest launch them?

Question 1

How would you structure this problem?

Take a minute to sketch your structure first.

Question 2

Using Exhibit 1, how many bowls does FreshNest need to sell to break even? What does that mean per store, per week?

Exhibit 1: Breakfast bowl economics

ItemValue
Price to retailers$4.00 per bowl
Cost to make and ship$2.50 per bowl
Fixed launch costs (marketing, retailer fees)$6M per year
Stores carrying the line10,000
Expected sales6 million bowls per year
Existing FreshNest meals, sales per storeAbout 20 per week

Case data is illustrative.

Breakeven = fixed costs / profit per unit.

Question 3

Consumer research shows that 30% of bowl buyers would otherwise have bought a FreshNest breakfast sandwich, which earns $1.00 per unit. How much profit does the line actually add in year one?

Lost sandwich profit counts against the bowls.

Question 4

The CEO walks into the room. What is your recommendation?

Lead with the decision. Aim for about 60 seconds.

Common mistakes

  • Falling in love with the product

    A clever product is not the same as a profitable one.

    Instead: test whether enough customers will pay enough to cover the costs.

  • Ignoring cannibalization

    New sales that come from your own products are not new revenue.

    Instead: ask what share of buyers would otherwise buy something you already sell.

  • Skipping breakeven

    Without a breakeven number, you cannot tell if the sales forecast is good enough.

    Instead: calculate breakeven and put it in everyday terms, like units per store per week.

  • Forgetting how it reaches customers

    A good product with no shelf space or marketing plan will not sell.

    Instead: cover channels, marketing, and timing in your answer.

  • Treating it as all or nothing

    Many launches are too close to call on paper.

    Instead: consider a test launch to prove the numbers before a full rollout.

Part 7 of 9

Variations you'll see

The same four questions apply to every version below. What changes is which one carries the most weight.

Line extension
A new flavor, size, or version of an existing product, like the FreshNest example. Cannibalization matters most.
New category
A product in a category the company has never sold. Capabilities and brand stretch matter most, much like a market entry case.
Premium or budget version
A higher or lower tier of an existing product. Watch for customers trading down.
Pharmaceutical launch
A new drug. Patient population, pricing, and insurance coverage usually decide it.
Digital product or subscription
Software or a subscription service. Focus on customer acquisition cost and how long customers stay.

Frequently asked questions

What is the new product launch framework in a case interview?

It covers four areas: customers (need, market size, willingness to pay), the product and competition, the economics (price, costs, breakeven, cannibalization), and go-to-market (channels, marketing, timing).

How do you structure a new product launch case?

Clarify the objective, understand the target customer, compare the product with the alternatives, test the economics including breakeven and cannibalization, then recommend launch, no launch, or a test with a plan for how to go to market.

What is cannibalization?

Cannibalization is when a new product takes sales from a company's existing products. Those sales are not new revenue, so the lost profit on the old product should be subtracted from the new product's profit.

How do you calculate breakeven volume?

Divide fixed costs by the profit per unit, which is price minus variable cost. If a product has $6M in fixed costs and earns $1.50 per unit, it breaks even at 4 million units.

How is a new product launch case different from a market entry case?

In a launch case, the product is new but the company may already know the market and customers. In a market entry case, the company is moving into a market it does not serve today, often with products it already sells.
