I would be really interested in the details of these kind of tools that are improving processes and productivity.

Are they reasonably documented/audited/put into any sort of version control like a lot of internal tooling? Or are they the kind of the thing that gets whacked together on the fly in a "move spreadsheet data from A to B", "I want a list of people's schedules with custom highlighting" kind of things.

Not doubting your productivity increase, I'm just curious how people quantify that when they say it.
