Commitment
An assignment is not a confirmation
In most programmes a slide says: Thomas Müller – Stream Lead Manufacturing. That does not prove Thomas Müller knows about it – and certainly not that he has accepted the responsibility.
In the model these are three separate things, and each of them is on the record.
What someone intended
Thomas Müller
Stream Lead Manufacturing
A · accountable
valid from 01.09.2026
assigned by · assigned on
What the person said themselves
e-mail sent
opened and answered
confirmed · time recorded
or declined – and then it becomes visible
What someone has to prove later
valid from and until
who assigned it
who changed it
when it was confirmed
what replaced it
When a person is replaced
This is where the difference shows most clearly. On a slide a name is overwritten – and afterwards nobody knows who was responsible in May.
The record then holds a sentence an auditor can read: “Nora Lindqvist (Stream Lead) was replaced by Farid Haddad (Stream Lead) – Traniva.” With the time, and with the name of whoever made the change.
