naygoo,
I have tried several methods for keeping tasks straight. Here is my not-so-brief history of task tracking:
I am fortunate in that I once was able to take the Franklin Planner class. I used a planner for several years sucessfully, but I found that manually recopying my task list everyday was cumbersome and not value added. I also didn't like carrying around the large binder. However, I very much liked their method of prioritizing tasks using symbols and numbers and I have used this in one form or another ever since.
I then tried to electronically keep a task list which eliminated the recoppying step, however when I was away from my desk I only had a hardcopy of the list, which required me to manually write down task, which I then had to copy into my electronic list when I returned to my desk.
I then began using a Palm Pilot which my company generously purchased for me. This allowed me to write down tasks electronically when I was away from my desk and then automatically "sync" the list when I returned to my desk. However, it had it's own problems, like running out of charge, and not being very durable as I occasionaly bounced it off concrete floors etc. Also, when I had a very long list I would have to "scroll" through several pages on the screen to see it all, which was inconvenient, and didn't provide me an easy way to view the overall size of the list to see how behind I might be. I also didn't like carrying it around.
I've also tried the posted note route, and I still use posted notes when I need to quickly write something down. However, I believe this looks unprofessional, and it's easy to lose them, so I tape the posted notes in my notebook (see below) if it's something I don't want to lose.
Currently I use a bound notebook, which seems to be very in-vogue at the moment with Engineers and Technical Managers. I write down basically everyting in this notebook other than formal calculations and data which I keep separate. I do write down the date each day so I know when I initially wrote down the task, note, etc.. I use a symbol to indicate a "Task", a symbol to indicated when I've started that Task, a symbol to indicated when I've completed the Task, and a symbol to indicate when I delete a Task that I am no longer required to complete. I also have a symbol for when I move a task before it is complete. This is usefull when I have a task that has been on my list for a long time (several pages ago). I can then "move" the task to the current page whithout losing the date when it was originally entered. I also mark the page in my notebook that has the oldest un-finished task so I don't waste time flipping backward through pages where everything is already completed. It is not a perfect system, in that no automatic "reminders" pop up, and if I lose my notebook (knock on wood) I'm quite lost. However, I think my current system has several advantages:
1) It looks professional and keeps me on task without being cumbersome.
2) My desk at least has the appearance that I'm organized, even if my notebook has a bazillion unfinished tasks that I'm late on.
3) Each morning I can quickly flip backward to see all of my unfinished tasks and how old they are by how many pages back they are and by the date they were entered. I normally do this as my computer boots up, or if I'm in a boring meeting, etc.
4) No battery, no docking station, no fragile electronics, and a low cost of equipment.
5) It is very free-form, e.g. I can still incorporate electronic lists and schedules if I desire by printing them out and taping them into my notebook.
