I have a lot of these, I do some work, send off files &/or emails to colleagues for them to do their part. if I want to hit the ground running when the colleagues finally make decisions I could act on (could be 2 minutes or 4 months later) then I need detailed notes to remind me where I got to, what I planned to do next, where the files are, what data problems I must not forget, etc.
The way I keep track at moment is keep an "in progress" file in my outlook calendar, copied to 9am Monday, updated most weeks, which has text notes like "Beans project progress: see if Tom wants to be coauthor, if Keri will do the stats her way or my choice, look at emails I sent on 2 Dec 22, files in dir = \bleep\bleep place" to try to remember what was decided or what wasn't decided yet, and how I thought I would proceed, and where the most recent key files are.
If this problem sounds remotely familiar, how do you keep notes on "sprase-activity" projects like this, where you end up doing a few hours at random long-apart times on the projects? How do you keep track of all the details? Sometimes I struggle to recall where files are or which version is most recent, etc. I know my system isn't perfect.
ps: I am junior person, no one to delegate to
