Why Provisor

Decision support, not a black box.

Provisor shows a likely answer, its range, and where it came from — so a planner can stand behind every promise.

A person commits

Provisor proposes; your planner decides. Nothing is emitted to suppliers or customers until someone commits it. Preview, refine, commit.
