I keep a listing of where I am with what on my phone (it's an old phone with little brain) so I have to be quite concise a typical entry looks something like this:
(A:2:R) Red car green car. Azure
it works something like this:
(role: position: action) Descriptor. Contact or contacts
Role (what am I to this production?)
(yes this can have more than one letter in it.)
Position (at what point in the process is this production currntly at?)
B: Between episodes
Action (What do I need to do or be doing to progress this thing?)
R: Record lines, music, write, source foley
S: Stalled Production, nothing I can do and it's been hanging in the air for more than 4 months.
W: Web update, this production is in good enough shape to be added to one of my websites as part of my CV or to Isotope audio as new content.
D: Dead Production, nothing I can do due to exterior forces it's dead.
N: Nothing, just hanging around waiting for someone to do their thing. (but not yet stalled).
Descriptor, is the production name and episode and Contacts relate to the other people or person involved if there are any.
So far it's a bit clunky but it's working quite well.
