La responsabilité unique n’est pas une clause — c’est de savoir si quelqu’un peut atteindre le site.
Un contrat peut nommer un responsable. Il ne peut pas mettre un technicien sur le terrain.
“Single point of accountability” is on every managed-service contract ever written. It is usually a clause. Clauses assign blame after the fact; they do not fix sites. Accountability that means anything is operational, not contractual. When a fault opens at 2 a.m. in a country you have never visited, the question is not who the contract says is responsible. It is whether one team can see the whole site, work out what is wrong, and get a certified engineer there, with the right kit, inside the window, without the job becoming a relay race between suppliers. Most “single accountability” fails at exactly that point. The contract names one party, but the work still runs through a chain of subcontractors, and the chain is where the hours disappear. Every hand-off is a place for the fix to stall and the blame to start. Real single accountability is the ability to carry a fault from alarm to a proven fix without a hand-off, and to show, afterwards, that someone was actually there. Not a clause. A capability.
