Dear Max,

>project? (Size, >dedicated, etc.?), per your letter ref a?
Typically you need 200M or so for the SDS data base on a project that might last several years of heavy communication. Of course the actual disk will be several GB because it has all of the other stuff for the opeatring system and other programs. My SDS record has 10 years of data. Each year the record gets a little bigger than the year before because I get more attuned to capturing nuance. My system has 500M for the SDS record and it is a little over half full, but of course that is influenced partly by the large size File Allocaiton Unit of 8K. A record will average about 6K, even though the record you received was closer to 20. I estimate that a team of 4 - 10 people working together on a project and all using SDS could be adequately supported by a 2 - 3 GB drive. In any event with the cost of hardware these days, capacity is really not an issue. The critical point is the design of the software so that creating and using this record is fast enough to keep up with the pace of daily business, so people can use the record instead of their recall.

>What software data storage do you use?, per your letter ref a.

The data is stored under a record created by my SDS program. I actually store formal correspondence and documents separately from the SDS (schedule and

diary) records. The latter are a continuous stream of "knowledge" that discusses (analyses) the objects, many of which are "documents" such as a letter, a budget, a CPM schedule, a plan sheet., etc. This is discussed a bit in the "Typical Day" scenario I sent the other day. I use the diary to "think" by writing about the correlation between documents and planning that does not show up in formal documents, e.g., things left out for strategic reasons. The result is that everything is managed by the SDS program to support the Communication Metrics process.

I look forward to your comments.
