Who lists what a change will touch?

In many companies change control turns into collecting signatures. But a signature is worth whatever sits under it: if nobody has written down which procedure, which training, which instrument and which customer requirement the change affects, the signature only shows that responsibility was distributed. The real work is the impact list, and producing it takes time — which is why it gets skipped. When a change comes back to bite, the question asked is exactly that: "did you consider this?" SenSight QMS keeps a planned change together with its assessment, approval and verification steps (ISO 9001 §6.3).
