The 4 Ps of marketing, worked through a launch case

The 4 Ps of marketing are product, price, place and promotion: the four decisions a company controls when it takes something to market. E. Jerome McCarthy set them out in 1960, building on Neil Borden's idea of a marketing mix. In a case interview, use them inside a launch, pricing or go-to-market structure, and test every P against customers, competitors and profit. Soreno, an AI voice interview practice app for consulting, investment banking and other finance candidates, runs a free pricing case with no sign-up, and full mock cases with an AI interviewer who hands you the data as you ask for it.

What are the 4 Ps of marketing?

The 4 Ps are the parts of the marketing mix a company can change: what it sells, what it charges, where buyers get it and how it tells them. Santa Clara University's Leavey School of Business puts it simply: the four have to line up, since a great product at the wrong price fails. Each card below is one P, with the questions a consultant asks under it.

Product

What is for sale, and the need it meets.

Need
What job does it do for the buyer, and how well?
Edge
Which features set it apart from what buyers use now?
Range
Sizes, versions, packaging, brand and service

Price

What the buyer pays, after discounts and terms.

Value
What is it worth to the buyer next to the alternative?
Rivals
What do competing offers charge?
Margin
What is left per unit after cost and the channel's cut?
Methods
Cost-based, value-based, competitive or dynamic

Place

Where and how buyers get it: the channels.

Where
Where do target buyers already shop?
Cost
What does each channel keep or charge per unit?
Reach
Stores, online, direct, partners, distributors

Promotion

How buyers hear about it and are moved to buy.

Message
What one reason to buy fits this segment?
Channels
Ads, sampling, sales force, social, PR
Payback
Does the budget earn back its cost?
Worked example: Copperleaf's protein bar (ours)6 steps

Copperleaf, an invented cereal maker sold in 8,000 grocery stores, wants to launch a high protein snack bar. The CEO asks: should we launch it, and how? This case and every number in it are invented by Soreno for practice.

  1. Clarify

    Launch, and win in year one

    Ask what success means. Here the CEO wants the bar to cover its $4 million first-year launch budget and to grow after. That makes profit in year one the test, and the 4 Ps the way to build the plan.

  2. Product

    Who it is for, and why it wins

    Case data: the bar targets people who already buy protein bars, and it has more protein than the two leading rivals with less sugar. Ask whether buyers would notice the difference and whether Copperleaf's cereal brand helps or hurts in a gym bag.

  3. Price

    $2.50 beats $2.00

    Rivals sell at $2.50. The store keeps 40%, so at $2.50 Copperleaf gets $1.50 a bar and keeps $0.60 after the $0.90 cost. At $2.00 it gets $1.20 and keeps only $0.30. To cover the budget, the low price needs 32 bars per store a week against 16 at the rival price, twice as many. Match the rivals and win on the product.

  4. Place

    Grocery first, online as a test

    Copperleaf is already in 8,000 grocery stores, so shelf space is the cheapest route. The team expects 18 bars per store a week, or 7.49 million bars a year, worth $4.49 million after cost. Online, direct to buyers, keeps more per bar ($1.00 after $0.60 of shipping) but case data puts it at 300,000 bars, worth $300,000.

  5. Promotion

    Target spend, break even at 6.67 million bars

    The $4 million budget is paid back at 6.67 million grocery bars, about 16 per store a week. The team's 18 clears that by only 2, so trial has to be strong. Spend it where target buyers are: sampling at gyms near stocking stores and shelf displays next to the rival bars, not national TV.

  6. Recommend

    Launch at $2.50, about $0.8 million in year one

    Launch in grocery at the rival price, with online as a small test. Grocery and online together earn $4.79 million after cost, about $0.8 million after the launch budget. Say the main risk plainly: the margin over the budget is thin, so track bars per store a week from month one and cut promotion in stores that stay under 16.

Where the 4 Ps fit in a case4 cases

The 4 Ps are rarely the whole structure. They fill in the part of the case about winning customers, next to the market, the competition and the economics.

  1. New product launch

    All four, then the payback

    Start with the market and the customer, then build the mix, then check that the launch earns back its cost. The worked case above is this kind.

    Practice: a premium pet food launch
  2. Pricing

    Price leads, the other Ps check it

    Set price from cost, competitors and value to the buyer, then ask whether the product, channel and message support that price. A premium price in a discount channel fails.

  3. Go-to-market

    Place and promotion lead

    The product exists. The question is which buyers, through which channels, with which message first, and what each channel costs per unit sold.

    Practice: a retailer selling online
  4. Sales or share falling

    Find the P that broke

    Compare each P with the competitor who is winning: a new rival product, a price gap, lost shelf space or a weaker message. Then size the gap in dollars.

    Practice: a shampoo brand losing share
4 Ps, 7 Ps and other versions3 versions

Several longer versions exist. In a case, the names matter less than covering what moves the client's result.

  1. 4 Ps

    Product, price, place, promotion

    McCarthy's 1960 set. In our view it is the version most interviewers expect, and it fits physical products sold through channels best.

  2. 7 Ps

    Adds people, process, physical evidence

    Bernard Booms and Mary Jo Bitner added three Ps in the early 1980s, for service businesses, according to Johnson & Wales University. Santa Clara's Leavey School of Business describes the 7 Ps as a response to service and digital businesses: people are the staff and culture, process is how the service is delivered, and physical evidence is the branding and setting.

  3. For B2B

    Solutions, access, value, education

    CUNY's marketing handbook cites a B2B rewording of the 4 Ps from a 2013 Harvard Business Review article, known as S.A.V.E. Useful when the client sells to businesses.

What do interviewers listen for when you use the 4 Ps?

Naming the four is easy. Interviewers listen for these four things.

  • The customer first

    Who buys, why, and what they use today, before any P. A mix with no target buyer has nothing to fit.

  • Numbers on the Ps

    Margin per unit after the channel's cut, volume per store, payback on the launch budget. The Ps become a plan once they carry a figure.

  • Ps that fit each other

    A premium price with a discount channel, or a mass message for a niche product, is the first thing a sharp interviewer will test.

  • A clear call

    Launch or not, which price, which channel first, and the one risk to watch, said in the first sentence of the recommendation.

7 case questions where the 4 Ps help

Under each question is what a strong answer does, and a link to practice it out loud. Sketch the mix first, then compare.

Launch a product

All four Ps, then the payback.

  1. A consumer goods company is deciding whether to launch a premium pet food line. How would you structure the decision?

    Sizes the premium segment first, then builds the mix around the buyer who would trade up, and checks the payback. Practice it, see a model answer

  2. A pharmaceutical company is about to launch a new drug. How would you set the price?

    Weighs value to patients and payers against the drugs in use today, not only the cost to make it. Practice it, see a model answer

  3. A software company is launching a new analytics add-on for its existing customers. How would you set the price?

    Starts from what the add-on saves or earns the customer, then checks it against the core product's price. Practice it, see a model answer

Go to market

Place and promotion lead.

  1. A furniture retailer with 60 stores wants to start selling online. How would you structure the decision?

    Compares the margin per order online, after delivery and returns, with the store, and asks which buyers would switch. Practice it, see a model answer

  2. An airline is deciding whether to raise its checked-bag fee. How would you think about it?

    Treats the fee as a price: how many travelers stop checking bags, switch airlines or pay, and what rivals charge. Practice it, see a model answer

Defend share

Find the P that broke.

  1. A leading shampoo brand has lost five points of market share in two years. What would you look at?

    Compares each P with the brand that gained: product, price gap, shelf space and message, by channel. Practice it, see a model answer

  2. Your client's main competitor has just cut prices by 20%. How should the client respond?

    Asks why the rival cut and which buyers would switch before matching, and looks at product and promotion answers too. Practice it, see a model answer

Common mistakes with the 4 Ps in a case

  • The 4 Ps as the whole structure

    A launch case also needs the market, the competition and the economics. The 4 Ps fill one branch of the tree.

  • Four lists, no decision

    Reading out ideas under each P without choosing. Each P should end in a choice the client can act on.

  • Price set from cost alone

    Cost sets the floor. Rivals and the value to the buyer set where the price can go, and the channel takes its cut before the client sees a dollar.

  • Forgetting the channel's cut

    In the worked case the store keeps 40% of the shelf price. Margin per unit is what the client keeps, not the shelf price.

  • Rivals standing still

    Assuming competitors won't react. A launch at a lower price invites a price cut back. Say what the two leading rivals would likely do and whether the plan still works.

Questions people ask

What are the 4 Ps of marketing?

Product, price, place and promotion. Product is what is for sale, price is what the buyer pays, place is where and how the buyer gets it, and promotion is how the buyer hears about it and is moved to buy.

Who created the 4 Ps?

E. Jerome McCarthy, in his 1960 book Basic Marketing: A Managerial Approach. He built on the marketing mix idea from Neil Borden.

Is the marketing mix the same as the 4 Ps?

Mostly. The marketing mix is the set of choices a company makes to sell an offering, and the 4 Ps are the most common way to group them.

What are the 7 Ps of marketing?

The 4 Ps plus people (staff and culture), process (how the service is delivered) and physical evidence (branding and setting). Santa Clara University's business school ties them to service and digital businesses.

Should I use the 4 Ps in a case interview?

Yes, as one branch, not the whole structure. A launch or go-to-market case also needs the market, competitors and the economics. Name the Ps that matter for this client and put a number on each.

Can I use the 4 Ps for a profitability case?

Not as the start. When profit fell, split it into revenue and costs first. If revenue is the problem, the 4 Ps help explain why buyers left or paid less.

How is the 4 Ps different from a market entry framework?

Market entry asks whether to go into a new market and how to enter. The 4 Ps decide how to win buyers once you are there, so they often sit inside the entry plan.
