I’m a big fan of documentation. I think it’s my favorite boring thing to do after coding. It brings the business so much long-term value that every hour invested into documentation by anyone saves literally x100 productivity hours across the company.

When I started the department I work in had zero documentation. Not the first thing. Now we have many hundreds of pages of it, all used frequently.

It has saved countless thousands of hours. It’ll save countless thousands more. I personally have written much of those docs. All told, I probably spent a hundred or so hours on them. But it means many other people are 10-100x as productive as they otherwise would be, and don’t have to bother others to complete their work (which further reduces productivity greatly).

Everything your team does should be documented. I make it part of any new task I assign. Before a work ticket is closed, documentation must be created.
