A verifiable public channel
A page can be revised when a source, assumption or limit becomes obsolete. A report can be prepared here and then sent to the publisher’s public form.
Marketing Strategy in Action

Expertise, sources and verifiable corrections
This information helps assess the author, the evidence method and how an error is handled.
Value analysis applied to market choices
Editorial work covers decision framing, market definition, segmentation, positioning, scenarios and multi-criteria arbitration. A method replaces neither the decision-maker’s data nor specialised legal, financial or sector expertise.
A hierarchy before interpretation
- Prefer the primary source and its most recent version.
- Retain the author, date, scope, unit and method.
- Seek contradictory evidence before generalising.
- Separate observed fact, estimate, assumption and recommendation.
Editorial correction history
- Quantified cases are identified as teaching simulations, their calculations are made reproducible and a public correction channel is added.
- Editorial direction and the limitation caused by the absence of a public correction channel were made explicit.
REPORT AN ERROR
Prepare a complete report

03 · Method
Five guideposts for reading the analyses
- 01Fact and interpretation
Check what is observed and what is inferred before using a conclusion.
- 02Obligation and guidance
A binding text, a guideline and a voluntary practice do not have the same force.
- 03Signal and trend
An isolated event becomes a trend only when several pieces of evidence converge.
- 04Conclusion and limit
A recommendation remains tied to the assumptions and conditions that could invalidate it.
- 05Traceable correction
A correction must identify the page, the passage concerned, the contradictory source and its date. The content and its limits are then reviewed together.
