examples where deadline is meaningful but not essential
Maybe if I give some examples, someone could help straighten out my thinking.
Project: HOMEREPAIRS ARE MADE: "I have a complete list of repairs jobs I can do with a helper". There is no deadline at the time it was entered but since it was triggered by need for various repairs, the list gets started.
notes:Some jobs I can list just by going from room to room in the house or walking around the outside of the house, others will only become evident until I start making the list and analyzing the problems, describing the intended outcome, and listing the materials and tools needed. Some of these will become projects in which a successful outcome is just a definition.
n/a

home inside-sit in each room for about 10 minutes and make list.
@home outside-walk around house listing problems.
issue:Helper is usually available on Mondays with 5 days notice but occasionally gives warning of major unavailability (like 2 weeks).
Some of the outside projects are weather dependent. Some projects will need assistance from a third person who is availalbe only at certain times. How do I incorporate the time aspects into the project description and work flow?
At work:
Project:ABC EVALUATION: meets client's needs, and is delivered on time. The data on ABC is collected, analyzed and put in report.
Note: The final analysis will depend on the purpose of the report and that will not be specificied until the data is examined in a preliminary way (is the data any good?). Then the report may or may not need to be written, the style and format, anmd due date of the report will depend on the quality of the data and choice the client makes.
Status:data is collected, preliminary analysis made, options presented.
@waiting for:client to call with preferred option.
Issue:the call comes and it has a time frame attached to it but it is negotiable. I need to check my availability to see if I can commit to deliver it by the dates offered. Either date I chose, I must make the graphs and charts two days before. I have several other of these in process any of which can have its time line changed at a moments' notice but I do not have to commit to a deadline unless I think I can meet it. Once I commit to it, I am stuck and have to deliver.
Any thoughts on how to make these kinds of things work?
