Title and introduction
Marketing mix: design, measure, optimise.
How can product, price, distribution, communication and budget be combined to meet a commercial objective while respecting resource, profitability and risk constraints?
Coordinated choices · Explicit assumptions · A revisable decision
Decision contract
Core question
— Does the mix operate as a coherent system that can be measured and revised?
Decision principle
— Each lever is assessed through its effects on demand, margin, the other choices and the capacity to execute.
Operational definition
The marketing mix is not a checklist of isolated levers. It is a set of interdependent choices about the offer, price, channels, communication and resources. A decision is defensible only when its expected effects, assumptions, constraints and next review point are explicit.
The levers belong together.
A price change can alter demand, margin, channel conflict and the proof required in communication.
The context is not an excuse.
Data availability, operating capacity, competition and contractual constraints define what can actually be tested and delivered.
The result remains revisable.
A chosen option needs a measurable signal, a review date and a condition for changing course.
Decision path
Understand · Diagnose · Design · Compare · Quantify · Measure · Optimise · Document · Review
Worked example
Free delivery is not only communication.
An online retailer considers free delivery above €60. The average basket is €54, the margin before delivery is 42% and the average logistics cost is €6.40. With the basket unchanged, contribution falls from €22.68 to €16.28. To preserve contribution, the basket must reach (€22.68 + €6.40) ÷ 42% = €69.24. The €60 threshold is therefore insufficient if the increase in basket value remains limited.
The decision affects price, channel, experience and margin at the same time. It must be tested as an economic rule, not presented as a simple advertising promise.
Decision checks and limits
- Identify the lever, its owner and its room for adjustment.
- State the offer, segment, channel, geography and period before analysing.
- Separate expected outcomes from the decisions intended to produce them.
- Quantify at least one economic or behavioural interaction.
The historical four families do not cover every capability needed by services, platforms or ecosystems. Classification does not establish causality; it organises choices before measurement. The same choice may belong to a different family depending on the unit studied: accountability matters more than the label.
