It brings to mind what I do when I am having problems with my focus. I keep something like a "ship's log" of my time. I just note the time of day when I start doing something and then the time when my concentration breaks. Next to it I write what I was doing. Now I have a record of what I did, something like
1543-1555 fooled around on Hacker News
1555-1602 bathroom
1602-1619 worked on presentation
1620-1643 worked on presentation
and so on. So I can look back and see that my focus wasn't very good- I 'came out of it' after just a few minutes. And in the same way that forcing myself to log what I eat helps my diet, after a few things like that above I find the discipline to keep persevering when my attention starts to wane.I think when we wear many hats we're susceptible to unproductive states of mind, and this little hack helps me a lot.
But I don't think it would be a good idea for public display. Depending on the boss, maybe it would be ok if s/he looked at it, but I dunno. I've never had a boss I didn't completely trust, but I think I'm pretty lucky that way.
Maybe snippets would work if they were just between a manager and his or her reports.
