In our factory we have a "Big Machine" which runs 24/7 and requires input and monitoring from different operators across various shifts. Every operator needs to be able to stop/start/control all processes (which may have been started by another operator) and this involves seeing status-bars etc. on the GUI provided by MegaCorp and installed on the Big Machine (i.e. not something I can readily architecturally change).
Currently this is managed by a having shared account on the Big Machine, which all operators know the username+password for. The password is long and secure, however since everyone always forgets it, it is written on a sticky note attached to the screen of the Big Machine, which is far from ideal. Operators do have their own accounts (used elsewhere in the factory) with passwords they do remember and are not shared.
This feels like a scenario played out in a lot of places (factories, hospitals, etc.), is there an Obvious Way to manage this so that all operators can work "like one user" but without actually having a shared account? Is there a better way to manage this without requiring MegaCorp to change their software to enable the same GUI to be accessed from multiple user accounts?
