For the task overview, we used a weekly planner. There was a place for tasks, which were numbered sequentially. If we had to transfer the tasks to later weeks, we just referenced it, we did not move it to the new week. The referencing system was week # and sequence #. E.g. 38/4. Once a task was done we striked it out. We also estimated how long time a task should take, and also jotted down how long it really took.
The weekly planner was the master for all appointments. Today, it is probably easier to use a calandering system on the computer, as you can subscribe to many calendars (work, private, activities as football, music bands,,,,,) and get the total overview over your use of time.
I seem to be missing a paper based system for planning a week. Maybe it is better to use the calendar on my computer, so others see that I am busy? Or should I use Evernote for archiving and referencing of old tasks? Need to test how it works out, I guess. Alternatively, use something like: Moleskin weekly pocket notebook.
