Decision-makers often ask for “data”, but what they really want is information which will help them understand a problem or a condition around the decisions they need to make. Yet they often do not know what data is available, what it is called, and how they might want that data or derived information expressed.
Decision-makers don’t want to worry about granularity of data, or how it is integrated, or how it is aggregated and transformed into information. They also are not interested in the various “qualifications” of information expression (all the stuff which should be placed in footnotes), even though they should understand (as Deming put it) the “weaknesses of the data”.
We will explore the data-to-information life cycle, and all the potential points of failure or misinterpretation along that path. We will also look at the analysis and graphic formats and techniques through which such information is expressed for human eye-brain consumption.
The role of context (historical, lateral, etc.) is important in moving raw data towards useful information. We shall survey examples and case studies which illustrate how important context is in understanding the true consequence of a data point.
For example, one common characteristic of most measures of business, society, and economic activity is constant growth. But the rate of growth and a declining share of total activity may be masked by that raw growth. We will explore simple mathematical and graphic methods for putting raw metrics into more meaningful context.
