Nowadays, with the advent of many software, I don't really know anymore to be honest.
Just go to any blog and check out their productivity section.
By productivity list, I was just loosely referring to all the outlines, wikis, notepads, to-do lists, grocery lists, mindmaps, grids, clippers, etc.
The list was mostly there to omit things like RescueTime, Pomodoro lists, Timeboxing and as you highlighted, some corporate metrics like quantity produced per annum.
Personally though, it is getting hard. I merely want to focus on the personal productivity side of it but that word "personal productivity" reads too long and most reasons why corporate productivity is separate from personal productivity is not really because of the self factor but that there are often methods tailored for groups that an individual couldn't execute on their own.
