- Avery- I like the typology (relevant;relevant but routine;
- relevant but uncontrollable). Try this on. I am working on
- information systems which require different "granualities"
- at different levels of use. The person at the top doesn't
- wan to be deluged, so he/she wants aggregation, but not loss
- of content. Those below want less aggregation, but not loss
- of the leaderships "vision" from the top. I'm looking at a
- model which puts everyone's information universe in a space
- that, in two dimensions, is a pyramid. The base of the
- shape is a time dimension (going right) and the hieght of
- the shape is a measure of granularity.
- People at the top have require less granularity, so the
- height of their pyramid is greater than those below.(Showing
- that their perception is more course - thier min scale is
- greater.
-
- The shape is trisected, so that the bottom part represents
- those "inputs" that represent things which can be considered
- stable during the relevant time span.(Relevant time span is,
- by the way, a function of the time in which the perceiver
- can respond to the input). The next portion up in the
- pyramid represents data that is predicably variable; by
- which I mean that it varies according to some pattern or
- routine KNOWN TO THE PERCEIVER. The top part of the pyramid
- represents information that the perceiver must treat as
- either random, or varying in an unknown fashion; and
- therefore is the part of the data spectrum faced by the
- perciever which must recieve the greatest "attention."
- Breakdowns in understanding of information among the layers
- of the organization are related to the distribution of data
- among the sections of the pyramids at each layer.
- (lowerlayer having shorter time lines, and lower "ceilings",
- because their perceptions are finer).
- I'm still working on getting this in PCT language.
