A few years ago I was finding myself annoyed by the lack of documentation at work. At the time I just complained and carried on. This raised my stress level and did not help anything.
I then decided to be the change that I wanted, and started writing documentation for things that I needed. Once you have a start you can ask questions and will find that others will help expand.
This applies beyond documentation. If I find something wrong that is put down to “that violates our policy” then I ask to see the policy in writing. It’s very common for there to be talk of a policy that does not exist.
If something is wrong or annoying you try to see what can be changed, how can you help to make this happen. Sometimes this just a case of getting the right people to talk to each other.
