GTD - Getting Things Done.
I rely on Omnifocus by the Omnigroup to manage pretty much everything I do. From the weekly shop to financial tracking. Within a work context however it has become almost indispensable. Large portions of my job require repeating processes over and over using multiple programs, processes and often computers. Omnifocus keeps me on track.
Turnovers
I keep a set of actions in an on-hold project called Utility. This has a fairly averasge set of actions that I perform over and over regardless of what project I might be on. 
Turnover Utility Actions
As basic as this action set is without it I’d frequently forget to do the Fx conform of Reel 4.
Some of the actions are not relevant to every project. For example, on most projects the codec that is requested from a picture department is what we actually receive. So the picture convert part is irrelevant.
For the record when doing picture conversions the only tool I now trust is MPEG Streamclip it is fast, can deal with batches and reliably outputs the correct codec at the correct frame-rate. QuickTime player on the other hand refuses to output a 23.976fps picture from H264.
Contexts
Still get really get a handle on these but kind of make it work. The best thing about Omnifocus for iphone (you knew it would have one) is within the contexts you can perform Business Searches. So for example my shopping list has a context of Groceries; within that context it searches for supermarkets. If I ave some time I can check to see what actions are available and as part of it I get a map of the area with all the supermarkets highlighted, pretty neat. I think so anyway.
All of the mix stages we use also have contetxs so if I need to move files or setup a mix session then I assign that to the action and it searches for Goldcrest/Pepper and tells me what needs to be done.
It’s my memory Cap’n she can nay take it
Progress bars tend to be a constant part of my day. I set this encoding, that downloading, another thing uploading to a playback system or the server, titan conforming or fixing. Without my beloved omnifocus I’d quickly lose track of where I was at. Did I put the final PB session for Reel 5 onto the FX machine? Quick check, Yes I did. Phew.
So there it is, my ode to omnifocus. It’s more than I ever need it to be but for what I need it to do it excels. Omnigroup also make some other wonderful programs such as Omniplan (Project Management), Omniweb (where my love for the company started but I’ve had to leave behind :( ) and many others that I can’t really place in my workflows. Thank you Omni!
