Traceability of audits
Touchscreens and monitoring computers can come with audit software logs at the same time, ensuring that when and where operations were performed can be accessed.
Create an Audit Trail or Operation Trail during operation, a document that can be used to track a complete record of which user ran what control function of the machine when.
Important processing phases must also be traceable to specific responsible parties, such as the use of electronic signatures, where operators sign with their ID number and password before saving a result.
Record the scope:
