What is a know-when tool

This tool represents the historical memory around certain entities, in terms of past events. Events and facts are recorded each time they occur and they can be retrieved via category, search function, or chronological log. This specific type of tool is also called white book. This name comes from the past (prior to the digital era) when a white book was always available next to each machine in production. There, relevant information was logged at each occasion to transfer this historical knowledge to colleagues covering other shifts.

How to use the white book

Relevant events are recorded and categorized in white books when they occur. Those facts can be easily retrieved via categories or search functions.
