01
Purpose of the site
Marketing Mix in Action publishes educational content, methods, example data and decision-support tools about designing, measuring and optimising the marketing mix. These resources are informational: they do not replace an assessment of the legal, financial, commercial or operational constraints that apply to a particular user.
02
Use of tools
Results depend on the data entered, the formulas described and the assumptions selected. Before acting, check the unit, time horizon, comparator, data quality and uncertainty range. No automated result is a guarantee of future performance. Google Analytics audience measurement is optional and requires your permission; its data are kept for fourteen months, without extension when you return, and are then deleted. The privacy policy describes this processing.
03
Content and downloads
Educational datasets and numerical cases may be synthetic. Their nature, dictionary and permitted uses are stated in the relevant resource. Intellectual-property rights and reproduction conditions are specified in the legal notice.
04
Availability and updates
The site may be corrected, expanded or temporarily unavailable. Methods and maintained objects indicate their verification date when it matters for interpretation. Substantive corrections retain a trace of the change and its possible effect on earlier decisions.
05
Applicable law
