We hired a new project manager and he decided that we should document our whole platform which was very lacking.

But now, for every minor feature/rework, he expects that it should also be documented. Currently, it feels we have too much documentation that is not easily searchable... Half our time is maintaining Jira and the other 40% is maintaining the code and 10% is developing new features....

Is there a thing as too much documentation?

Client: "When can you deliver this feature, so we can move on?"

Me: "Well, by the end of the week could be feasible."

Client: "Perfect!"

Me at the end of the week: "It is finished."

Client: "Thanks!"
Client proceeds to not use the feature for over 3 months.

Three key traits of software developers are laziness, impatience and arrogance.
