Subject:	OHS Use Case Align with DKR Purpose
	Towards an Atomic Data Structure

Dear Eric

You indicate in your letter today that "Use Case" analysis will explain how technology for the OHS/DKR will improve daily work, from examples in my letter to you on April 23, 2000, and thereby improve earnings by saving time and money.

So far, examples of Use Case have seemed remote and esoteric. As well, others today have provided excellent explanations of Atomic Data Structures, but the connection with performance of daily work remains to be established, which is the ultimate purpose of the exercise. Doug calls it handling daily working information.

To help focus on the issue of augment, here is an example of a simple matter getting DSL service up and running, that uses the record to help people align their work with requirements and commitments. Can you indicate how this "use case" differs from what is expected to be accomplished with the improvements the team proposes for the OHS/DKR?

Another way to frame the issue is that the quality of reasoning can be improved by integrating time and information as a predicate to solving difficult world problems. It seems likely that before we get to the hard problems, we have to first be able to improve how smaller problems can be solved with greater dispatch, under Aristotle's rule about the magnifying effect of time on small deviations in the beginning.

I realize you are busy, so maybe others on the team can help with this issue.

Sincerely,

THE WELCH COMPANY
