STP · Customer-centric Market Strategies

The core idea

Customers are heterogeneous, so averages mislead. STP is the disciplined response: segment the market into groups with common needs, target the segments where size, fit, and competitive room create the most profit, then position by defining a value proposition that lives clearly in the mind of those customers relative to alternatives. It answers the two strategy questions — where will we play, and how will we win — and sets the brief that the 4Ps must execute. — after Smith and Kotler

Put simply · Choosing which race to enter, not just training harder.

Imagine you are a runner. You could train for sprints, marathons, or hurdles. The market is everyone who runs. Segmentation says: these groups have different needs. Targeting says: which race are you actually going to enter, given your build and the competition? Positioning says: once you've chosen the race, what do you want people to say about you when you line up?

Mobil did this at petrol stations: five segments of drivers, each with different needs. They targeted Road Warriors and True Blues — not Price Shoppers — and built convenience stores designed for the people who stayed longest. They said no to 20% of their volume to win a different 32%.

The mistake most companies make is trying to run all three races. Averages mislead. The person who is 40 years old on average is two people who are 25 and 55, with completely different needs.

The hero diagram

Segment, Target, Position

A three-stage cascade. Each stage narrows the market and sharpens the choice; the output of one is the input to the next.

1

Segment

Discover and profile groups of customers with common needs. Use bases (the why — needs, motivations, behaviour) and descriptors (the who — demographics, geography) so segments are differentiable, measurable, accessible, actionable, and substantial.
2

Target

Evaluate each segment on the 3Cs — customer value (size, growth, reachability), company fit (objectives, capabilities, resources), and competitive intensity (underserved needs, rivals' strengths). Targeting is the discipline of saying no to the segments you will not serve.
3

Position

Define a value proposition that places the offer in the customer's mind versus alternatives — for whom, what benefit, and how it differs. The positioning statement becomes the brief that drives Product, Price, Place, and Promotion.

STP Cascade · after Smith (1956) & Kotler

Segment — discover groups with common needs · Target — choose where to play · Position — define how to win in the mind

The cascade is sequential: weak segmentation produces weak targeting, which produces a positioning statement with no real audience.

Criteria for Good Segmentation (DAMAS) · Kotler

Differentiable · Actionable · Measurable · Accessible · Substantial

A segment that fails any one of these five tests will either not be reachable or not be worth reaching.

Targeting 3Cs · marketing-strategy tradition

Customer opportunity — size, growth, reachability · Company fit — objectives, capabilities, resources · Competitive intensity — underserved needs, rivals' strengths

Targeting is the discipline of saying no — the segments you decline define the strategy as much as the ones you choose.

Positioning Statement · Kotler · Lafley & Martin

For (target customer) · who (need) · the (product) is a (category) · that (core benefit) · unlike (alternatives), our product (point of difference)

A positioning statement is only useful if it would embarrass a competitor — vague statements are not positions.

How to apply

Build an STP for one offering you own.

List the bases first, not the descriptors. Start with the "why" — needs, motivations, behaviour. Demographics follow; they are how you find segments, not what defines them.
Apply DAMAS to each candidate segment. Is it differentiable, actionable, measurable, accessible, and substantial? Cut any that fail two or more tests.
Score remaining segments on the 3Cs. Customer opportunity, company fit, competitive intensity. Target the one with the best combined score — not just the biggest.
Build a perceptual map of the target segment. Plot competitors on the two axes that matter most to that segment. Find the unoccupied position with genuine demand.
Write one positioning statement. For [target], who [need], [product] is [category] that [benefit]. Unlike [alternative], it [difference]. Test: would a competitor be embarrassed by this claim?

Key reading · Lafley & Martin · Playing to Win · 2013

Strategy as an integrated cascade of choices.

Lafley and Martin frame strategy as five nested choices — winning aspiration, where to play, how to win, capabilities, management systems — and show that STP is the marketing expression of the "where to play / how to win" pair. The Chase Sapphire Reserve case in the course is a worked example: segment (affluent millennials who travel), target (HENRYs over price-shoppers), position (premium travel rewards with aspirational identity).

Strategy without a clear target is a wish. STP converts it into a choice.
