0808 - Summary/Objective
080901 - Follow up ref SDS 25 0000, ref SDS 24 0000.
080903 - Began a spreadsheet to calculate the risk of error and consequent NPV
080904 - of avoided extra cost based on the number of communications that occur
080905 - on a project from one month to the next. This will answer Steve
080906 - Rule's question about calculating added value, ref SDS 15 line 85.
080908 - It will recognize value at risk, reviewed on 970703. ref SDS 21 9800
080910 - Want to reflect research performed the past few weeks, per the
080911 - references in Other Files listed herein. A key objective is to
080912 - demonstrate the entropy cited in the paper by Air Force Institute of
080913 - Technology at ref SDS 24 line 302, that supports an "entropic cost
080914 - model," per ref OF 3 line 142, and corresponding benefit of investing
080915 - time for Communication Metrics to build and maintain shared meaning,
080916 - align communications, and manage the record to facilitate preparation.
080918 - This model should provide a method by which the uncertainty of
080919 - information can be quantified in a structured manner. The method will
080920 - be useful for determining staffing to avoid being overwhelmed, and the
080921 - impact of adding Communication Metrics. It will provide an alternate
080922 - basis, or cross-check, to estimate the cost of "managing" from
080923 - traditional order of magnitude calculations prepared based on a
080924 - percentage of direct cost. The need arises because typically
080925 - "overhead" staff is set as a percentage of direct cost, per discussion
080926 - with Steve at Turner, ref SDS 13 line 126, and additional staff is not
080927 - provided until it is much too late to avoid the problem of noise, ref
080928 - SDS 24 line 280.
080930 - [See letter to Ray Levitt for research on communication errors,
080931 - ref SDS 27 line 91.]
080933 - The first approach will be to experiment to determine the rate of
080934 - growth in communications, based on initial parameters.
080936 - Tried estimating the number of communications based on the number of
080937 - events where information is transferred between people.

080949 - We need a column for exposure and then set error rates based on
080950 - the amount of preparation that can be done. Preparation will be
080951 - a function of time invested to manage the record.
080953 - Want to calculate the growth in staffing requirements as a
080954 - function of the number of subjects and participants involved.
