Knowledge Management and Time

TARDIS

Time, like the term knowledge, is an elusive concept. Like knowledge, a definition of time that is satisfactory to everyone has defied the greatest minds from Antiphon to Newton, and on to Einstein and Planck. Yet time is pervasive across cultures, and at least in the Western world, drives much of what we do. Time is also intrinsically linked to knowledge management, and provides some insights as to why knowledge management is so difficult.

Take for example the common platitude –“just in time knowledge management”. I take this to mean that the right information (I have chosen my words carefully) should be available to decision-makers at the right time and in the right place, and not before or after the time it is actually required! Now this begs all sorts of questions, like:

  • How do we determine what is the right information?
  • How do we know who should receive that information?
  • What is the right format for the information, so it can actually be used?
  • How do we know what the right time is?

I could go on but you should get the idea of just how difficult, if not impossible this is. This brings me to my second idea – knowledge management is about the effective use of data or information at some future point in time. Our knowledge management activities collect data, or information, or even anecdotes, from the past and try to make sense of them so we can do something in the future. We use these collections and apply previous experience, and perhaps some context, to predict an outcome. In other words we expect a better outcome as a result of our efforts.

Again this begs all sorts of questions, like:

Is the Pyramid to Wisdom Model Useful?

There is a good deal of criticism of the data, information, knowledge, wisdom model of knowledge, which is sometimes called the DIKW hierarchy but I prefer to call it the ‘pyramid to wisdom’. Most of the criticism says the model is too simple. I wonder, however, if the model has some use. As usual it is useful to return to source documents.

In knowledge management circles Russell Ackoff is usually credited as the originator of the hierarchy, and indeed published two seminal papers, the first in 1989. However Milan Zeleny published a paper two years before Ackoff, and Harlan Cleveland published a paper in 1982. Both of these authors mention the hierarchy and provide examples.

I personally find the explanations all authors provide to be quite useful. For example Zelany says - “While data and information are piecemeal, partial and atomized by their very nature, knowledge and wisdom are ‘holistic’ related to and expressed through systemic network patterns, integrative by definition”. He goes on to say – “To manage wisely implies knowing why to do something; to manage effectively implies knowing what to do; to manage efficiently implies knowing how to do it (and to ‘muddle through’ implies nothing and having ‘lots of data’ around)”. I would be surprised if these descriptions do not resonate with you.

The Knowledge Conduit

About three years ago I came up with the idea of the “Knowledge Conduit”. The idea is still a bit raw but I thought I would share it with you anyway. The Knowledge Conduit is illustrated below.

 

The Knowledge Conduit

First, you should observe that there are two distinct domains – the descriptive domain and the predictive domain – and that data and information belong to the descriptive domain. I like Davenport and Prusaks’ (1998, pp 2-3) definition of data as being "a set of discrete, objective facts existing in symbolic form that have not been interpreted". The symbolic form may be text, images, or pre-processed code. Data is usually organised into structured records, however it lacks context. The declaration ‘Iron melts at 1,538 degrees Celsius.’ is a data statement because it has no context.
