Which levers actually move the business.
Most marketing plans allocate effort across product, price, place, promotion, people, process and physical evidence without ever comparing them. Each area has a specialist who owns it, a budget line that survives on precedent, and a case for more.
The result is a plan where everything is important, which is the same as a plan where nothing has been chosen. The trade-offs that would make it a strategy are the ones nobody is asked to make.
The seven levers are read against each other rather than one at a time. Each gets the same four questions: does it pay, does it build recognition, does it open future options, can this organisation actually run it. Then each gets its own instruction for the planning period.
Reading them together is what surfaces the transfers. A promotion programme funded by a service reduction, a price position propped up by a process the business cannot sustain: these are invisible while each lever is reviewed by the person who owns it.
The marketing mix uses the same instruction set as media, operated against the seven levers rather than against channels. Increase. Hold. Reallocate. Pause. Exit. Trial. Test. One instruction per lever per planning period, each with a named owner inside the business, a timeline and the date it will be checked. The same word can be issued against two levers in opposite directions, which is usually the most informative part of the output.
You bring what you already have: the current plans for each of the seven levers, product, price, distribution, promotion, people, process and the physical evidence customers see, plus the numbers behind them. Before any scoring starts, one declaration gets made: who the audience is, what they do now, and what you want them to do. No defensible declaration, no reading.
Each lever gets read through four lenses: what it contributes in revenue, margin and cash; what it does for the brand in the customer's memory and on the shelf; what future options it opens; and whether the business can actually run it. The four readings are combined, weighted by how reliable each line of evidence has proven, into a single result with an honest statement of how sure it is.
What arrives is one instruction per lever for the planning period: Increase, Hold, Reallocate, Pause, Exit, Trial or Test. Each carries a confidence level, a named owner inside your business and the date it will be checked. The same word can land on two levers pointing in opposite directions, which is usually the most useful page in the pack.

The mix has grown from four Ps to seven without ever acquiring a rule for choosing between them, which is a remarkable outcome for a framework taught continuously since 1960. The marketing productivity literature that was meant to supply that rule produced return-on-investment measures that each lever's owner could calculate separately and none of them could compare. Volume IV reads the seven together and issues one instruction each, which is a modest ambition the field has managed to avoid for sixty years.
And commercially: it names which lever to stop funding.
Twelve months after a reading, the instruction is compared against what happened and the result is recorded, whether or not it is flattering.
A marketing mix reading settles the question most plans avoid: which of the seven levers, product through to the evidence customers see, deserves more next year, which deserves less, and which should stop. Each lever gets one instruction, a confidence level, a named owner and a check date. It starts simply: you describe the decision, Rob reads whether the method fits it. Send one sentence: what is the decision you are trying to make?
