Marketing Mix (4Ps and 7Ps)

The marketing mix is product, price, place, and promotion, extended with people, process, and physical evidence for services.

The questionFor the customers we chose, how should product, price, place, and promotion, and the three service extras, work as one offer?

4Ps. The services extension is the 7Ps. Borden's earlier list is often called the original marketing mix.

4Ps

Product What is offered
Price What it costs the customer
Place How it reaches them
Promotion How they hear about it

7Ps extras

People Who delivers the service
Process How the service is delivered
Physical evidence Tangible cues of quality

McCarthy's four levers, then the three Booms and Bitner added for services.

When to use it

STP has named a target and a position, and the team still has a product, a price list, a channel, and a campaign that were built for "the market" as a whole.
A service business is losing on delivery, wait times, or the look of the premises, and marketing keeps answering with more advertising.
Two of the levers have been changed, such as a new bundle and a new price, and channel or sales script still describe the old offer.
A launch plan lists features, media, and discounts in separate decks, and nobody can say how they fit one customer.

When to avoid it

The target is not chosen. Mixing product and price for everyone produces an average offer. Do segmentation, targeting, and positioning first.
The question is how much volume a price change will move. Elasticity sizes that. The mix only says that price is one lever among others.
You are diagnosing a sales conversation or a multi-buyer deal. Challenger or Miller Heiman is the tool, not a list of Ps.
The work is a brand-equity study. Equity is what the name adds. The mix is the set of decisions that built it.

Overview

The marketing mix is the set of controllable decisions that turn a chosen target and position into an offer. McCarthy’s 1960 version is product, price, place, and promotion. Booms and Bitner added people, process, and physical evidence in 1981 for services. The choice it supports is how those levers should be set together, and what should stop, so the customer meets one offer rather than four separate projects.

The four, or seven, only work as a set and only for a named target. Changing promotion while price and channel stay put is a campaign, not a mix. The extra three are not decoration. In a service, the person, the process, and the premises are often what the customer is actually buying.

The four Ps, and the three for services

Product

The offer itself, including features, quality, range, packaging, brand, and after-sales. For services it is the core performance the customer is buying. Changing product without changing how it is sold or priced leaves the rest of the mix describing something that no longer exists.

Price

List price, discounts, payment terms, and the perceived trade of money, time, and effort. It is the only P that produces revenue directly. A price that does not match the product and the channel trains customers to wait for a discount or to walk away.

Place

How the offer reaches the customer, including channels, coverage, inventory, and delivery. Online, direct sales, distributors, and retail are different places, and each one constrains price and product. A premium offer in a discount channel does not stay premium.

Promotion

How the customer hears about the offer, including advertising, sales force, public relations, and sales promotion. Promotion that claims a position the product and price do not support is spent twice, once on the media and once on refunds and lost trust.

People

Everyone the customer meets, and the hiring, training, and incentives that shape them. In a service, the person often is the product. A script and a campaign cannot offset an untrained or mis-incented front line.

Process

The steps the customer goes through to buy and receive the service, including wait, handoffs, and recovery when something fails. A smooth process is part of what is sold. A broken one is what customers tell others about.

Physical evidence

The tangible cues of a service, such as premises, uniforms, reports, apps, and packaging. They stand in for quality the customer cannot inspect in advance. Inconsistent cues make a consistent claim unbelievable.

What it is not

A checklist to complete once. The levers have to be set together for one target, and they drift as the offer and the channel change.
A creative brief. Promotion is one lever. Product, price, and place have to match it, or the brief describes an offer that does not exist.
A substitute for targeting. The mix is how you serve a chosen segment, not how you choose one.

The steps

Start from the target and the position

Name the segment and the place the offer is supposed to hold against named alternatives. A mix with no target is four independent projects.
Write the current mix as it actually is

For each P, record what customers actually get, pay, use, and hear, not what the brand book says. Include people, process, and evidence if the offer is a service. The gaps between the stated mix and the real one are the first findings.
Change the levers as a set

Pick the smallest set of changes that would make the offer match the position. If price moves, check channel and message. If the service process moves, check people and physical evidence. Write down what will stop, not only what will start.
Cost the mix and assign owners

Put a cost, an owner, and a date on each change. Promotion is easy to spend and easy to measure. Product, place, and process usually decide whether the spend can work.
Track by the target, not by the average

Watch conversion, margin, and retention for the chosen segment. A mix that lifts the target and leaves the rest flat is a success. An average that hides that is not.

In practice

A regional HVAC firm sells the same three packages, repair, annual tune-up, and full replacement, at one set of prices, through inbound calls and Google ads. Replacement close rate is 18 percent against national chains. Last year's media spend was $144,000. The team writes one mix for the households that have already had a repair in the last 24 months, about 6,200 addresses. Product is a same-week emergency repair plus a five-year parts plan on any replacement that follows, not a catalog of equipment SKUs. Price is a $89 diagnostic fee, credited against the job, instead of a free quote. Place is two exclusive plumber partnerships in the two ZIP codes that already produce 40 percent of replacements. Promotion stops category search ads and puts the same $12,000 a month into the partners and a mailer to those 6,200 homes.

After one heating season the replacement close rate in those two ZIP codes is 31 percent. Diagnostic-fee jobs carry 8 points more gross margin because fewer unpaid quotes are written off. Search-ad spend is zero. The mix did the work only because the target was narrow enough that product, price, place, and promotion could all change together. A firm-wide new slogan on the old free-quote process would have left the numbers where they were.

What you leave with

A one-page mix for each target, with the current state and the intended state for every P.
The changes that will stop, not only the ones that will start.
An owner and a cost for each change.
Segment-level measures for conversion, margin, and retention, with a review date.

Failure points

Promotion standing in for the mix

The campaign changes and the product, price, and channel do not. Customers arrive and find the old offer, so the spend buys disappointed traffic.

One P optimized against the others

Purchasing cuts product cost, sales adds discounting, and e-commerce opens a channel the brand cannot police. Each move is rational locally and the offer as a whole no longer matches the position.

A mix for everyone

The same product, price, and message are aimed at every segment. The mix then restates the undifferentiated offer STP was meant to replace.

Service extras ignored

A service firm treats the 4Ps as complete. Hiring, the customer journey, and the premises never enter the plan, which is where the customer actually judges the firm.

Set once at launch

Channels, costs, and competitors move, and last year's mix is still in the annual plan. The four lists stay tidy and the offer drifts.

The failures above are usually Commercial Acumen: the work was not tied to money, for the client and/or for you.

Origin

Neil Borden of Harvard popularized the phrase "marketing mix" in teaching from the late 1940s, taking James Culliton's image of the executive as a mixer of ingredients. Borden's 1964 Journal of Advertising Research article listed about a dozen elements, including product planning, pricing, branding, channels, personal selling, advertising, promotions, packaging, display, servicing, physical handling, and fact finding. E. Jerome McCarthy reduced that list to four controllable variables, product, price, place, and promotion, in Basic Marketing: A Managerial Approach, published by Richard D. Irwin in 1960. That four-part version is the one most practitioners use.

Bernard Booms and Mary Jo Bitner added people, process, and physical evidence in 1981, in a short chapter for service firms in an American Marketing Association collection. Services are produced and consumed together, vary with the person who delivers them, and leave little for the customer to inspect in advance, so the extra three are meant to manage that. Philip Kotler's textbooks spread both versions. None of the labels is trademarked.
