I don't know the answer to this issue of depenancies. Let's say you have an action on your list (buy food) that you will do or are waiting for and some dependant actions in your support material (awaiting replies, make food if only 12 are dining, order from caterer if more than 12 are dining). The project has a deadline (July 4th) but there is a large window as to when you will hear from everyone but you need to have enough time set aside for shopping and food preparation if you are coooking it and, if you are ordering it, you need to let the caterer know by a certain date and you need to have reserved sufficient money for that. Do you just put these dates on the calendar as well as your project support materials?
Jamie,
Most projects are a lot like this; they are rife with contingency and uncertainty. They cannot be microplanned many days, weeks, or months in advance.
Remember, GTD is flexible, and what and how you will plan a particular project is determined in part by your experience and confidence doing similar projects.
For your example, let's assume that you do not do this kind of entertaining very frequently and you want to document your actions with care.
Let's further assume that the caterer requires 2-weeks notice for events of this size. Let's assume that it takes you less than 2 weeks to plan and purchase food yourself for an affair of 11 or fewer people.
So, the above assumptions tell you that June 20 is the drop-dead date for notifying the caterer of your plans. I'd put that on my project plan and on my calendar.
Now, you know your guests, I don't, but I'd want to give myself a few days before the drop-dead date to draw up the final list of attendees. So, I'd calendar June 16 to list all attendees who have not RSVP'd. This would also go on the project plan. On that day I would call (e-mail, carrier pigeon) all the people on that list to find out what their plans are. This action would also go on the project plan and calendar.
Your actions are contingent and not predetermined. But there are some key dates that would go on my calendar. As I get more information, I would update my project plan. I might want to talk to the caterer even before I know exactly how many guests I will have. I might use this information to help me plan my budgeting.
I might set this project up with a few subprojects: (a) guest list finalized; (b) financial resources accumulated; and (c) menu planned. Some obvious NAs would go in my trusted system. A lot of actions would go on the calendar. Almost everything would go on the project plan. As the event approaches, I would review the project plan daily.
There are so many points on the decision tree where there are a number of possibilities and those possibilities are not known very far in advance. It doesn't make sense to overplan the dependent actions in a project that has a high degree of contingency. But you do need to know your firm deadline dates so that you can get them in your calendar and into your project plan.
