Combien de jours tenez-vous ?
30 fiches pour sécuriser la supply chain de votre PME
· 37 pages· In French· ISBN 978-1-0654997-3-2
On 22 October 2026, London asked every British household to be able to last three days without help. What about your company? How many days without its first supplier, its server or its biggest customer? Thirty sheets, one a day, to replace “I think” with a number of days: see, count, close the gaps, rehearse, last. Each sheet fits on one page, with a duration and an owner. None needs software (in French).
What you will find inside
- Thirty one-page sheets, one a day, each with a duration, an owner and four concrete actions.
- Four weeks to see, count, close the gaps and rehearse, then two sheets to make it last.
- Time to survive and time to recover, the MIT method, worked out without software.
- Verified, sourced cases: Genex UK, Octave, OVHcloud, KNP Logistics, Toyota.
- At the end: your three priority gaps and a continuity plan that fits on one page.
Who it is for
Owners and managers of small and mid-sized companies, with their leadership team, in any sector.
« Ce livre ne vous demande pas de prévoir le prochain choc. Personne ne le peut. Il vous demande de savoir combien de jours vous tiendrez, puis d’en gagner. »

Thirty minutes on the phone is often enough to know whether a diagnostic makes sense, and on which scope. No commitment.
