Marketing mix diagnostic

A diagnostic makes the assumptions behind a marketing mix inspectable before an organisation changes price, offer, channel, communication or budget. It is a structured exploratory assessment, not a performance forecast or causal proof.

What to assess

Review the links between offer and segment, value and price, price and channel, availability and demand, promise and delivery, budget and capacity, and measurement and decision. A strong average must not hide a blocking interaction.

How to use the result

For each interaction, document coherence, evidence quality and economic impact. Prioritise the issue whose uncertainty and consequence make the decision most fragile. Explore the coherence method to turn that priority into a testable question.

What the score cannot show

The score reflects declared assumptions. It does not establish observed performance, causality or a universal benchmark. Validate important ratings with commercial, operational and financial data.

Next decision

Choose a reversible investigation, name the missing data, set a threshold and fix a review date. The purpose is to improve the decision record, not to replace human judgement.
