The sign-off

The record that operations agreed the promise is deliverable.

The part

What it is

A short, dated agreement that the promise can be kept at the stated cost. It takes an hour and it changes how the promise is treated for years.

Where sign-off cannot be obtained, that is the finding: the promise is wider than the organisation.

The smallest level

The attributes it carries
