Overview

The 4Ps Marketing Mix was introduced by E. Jerome McCarthy in Basic Marketing: A Managerial Approach (1960, Irwin), one of the most widely adopted marketing textbooks of the 20th century. McCarthy organized marketing decisions into four categories: Product (what you're offering), Price (what you charge), Place (how and where customers access it), and Promotion (how you communicate it). Philip Kotler later expanded and popularized the framework through Marketing Management (first edition 1967, Prentice Hall).

For service businesses, the 4Ps were found insufficient, leading to the 7Ps extension attributed to Bernard Booms and Mary Bitner in a 1981 paper on service marketing. The three additions:

Jobs-to-be-Done (JTBD) offers a fundamentally different and often more illuminating lens. The framework is most closely associated with Clayton Christensen, elaborated most fully in Competing Against Luck (2016, HarperCollins), co-authored with Taddy Hall, Karen Dillon, and David Duncan. The core idea: customers don't buy products — they "hire" them to make progress in a particular circumstance. Understanding the job (not the product category) reveals what customers actually value and where unexpected competitors could disrupt you.

The two frameworks work together: the Marketing Mix tells you what the firm is doing; Jobs-to-be-Done tests whether it matches what customers actually need.

When to Use It

When the client's question involves customer behavior, market position, go-to-market strategy, or why customers are or aren't buying. The Marketing Mix is fast and structured for an internal diagnostic: are we making the right offering, at the right price, available in the right place, communicated the right way? JTBD is most powerful when grounded in actual customer data — it's investigative by nature.

How It Works

4Ps / 7Ps Audit

For each element, assess: is this consistent with the brand promise? Does it create or destroy value? Is it differentiated from competitors, or parity at best?

Jobs-to-be-Done

  1. Identify the circumstance: what specific situation triggers the customer to seek a solution?
  2. Identify the functional job: what practical outcome does the customer need?
  3. Identify the emotional and social job: how do they want to feel? How do they want to be perceived by others?
  4. Evaluate how well current solutions do those jobs: where are customers underserved? Where are they hiring workarounds?
  5. Find the gaps: which jobs are consistently underdone? These are the opportunities — and the vulnerabilities, if a competitor identifies them first.

Running It in a Session

Use the Marketing Mix for a rapid audit of the client's current go-to-market: does the offering, price, channel, and communication form a coherent whole? Assign the Analyst to structure the audit; it can be done in 15–20 minutes with the information in the Client brief.

Then use JTBD to challenge the deeper assumption: "Are you optimizing the product you want to sell, or the job the customer is actually trying to hire for?" This reframe frequently opens up the conversation — clients who thought they had a pricing problem discover they have a job-definition problem. The Skeptic should push on what evidence the team has for the jobs they're hypothesizing.
