Due to potential threats on the internet, most advice given is to install updates as quickly as possible. While the advice is generally good for App Updates, it is not so good for OS Updates and Upgrades.
When OS Updates and Upgrades are available, they should be tested first, on one user, a spare computer or device before being installed on all currently used computers and devices. All the functions you and your users perform need to be confirmed, require updated Apps from the developers or need reconfiguration.
The guidelines here do take time, updates will take less time than upgrades, but it is time better spent than dealing with users complaining that they cannot work as their Apps don't work and having to revert back via backups.
If spare systems are an issue, consider having Virtual Machine software available, so no extra hardware is required. In further posts, suggestions will be given for a Virtual Machine setup.
For OS Updates & Upgrades, certainty of installing is better than a quick install.
