An illustrative checklist for a fictional range. A real programme defines the tolerance, the sampling method, the inspection window and the remedy if a batch fails.

The four things a programme needs in writing.

The tolerance, the sampling method, the window in which inspection happens, and what happens if the batch fails. Without all four, a failed delivery becomes an argument rather than a process.

Why the hardest feature is called out separately.

Because it is where the process will drift first, and recording it at first article turns a future argument into a baseline. A report that measures everything equally has not decided what matters.
