Acceptance criteria and where each stands
Thornbury order-to-cash program Order entry redesign: changes requested Criterion 4 held
The acceptance record for the Order entry redesign milestone: five agreed criteria, the evidence submitted against each, and the one decision only Robert Lang can record. The milestone fee is not invoiced until his acceptance carries his name, a version and a date. Prepared by Tom Becker, PMO lead at Corbel Partners, for Robert Lang, chief operating officer at Thornbury Components, and Claire Dubois, engagement partner. Record as of Thursday, October 1, 2026.
Done means the evidence is attached and complete. It does not mean accepted: Robert Lang records acceptance himself, and nobody at Corbel records it for him. His acceptance of version v1.2 is not yet recorded.

The acceptance queue
Every Thornbury milestone waiting on a reviewer is Ready for acceptance, Changes requested or Disputed. Order entry redesign sits in Changes requested, owned by Tom Becker, priority Urgent, with the plant three test results as its blocking item. The live table below lists the milestones waiting on a reviewer or on evidence.
