Information is not knowledge (and knowledge is not wisdom)
Some reflections by Nick Milton on why knowledge management within organisations is so poor. If I were him, I would have included the below illustration from gapingvoid as I think it illustrates his five points rather well.
Firstly much of the knowledge of the organisation is never codified as information.Source: Why you can’t solve knowledge problems with information tools alone | Knoco Stories[…]
Secondly, a common problem (a corollary of the first) is that project knowledge may never have been recorded in project documents.
[…]
Thirdly, and a corollary to the first two, the vast majority of project information is not knowledge anyway. If you are relying on project documents as a source of knowledge, you will be relying on a very diluted source - a lot of noise and not much signal.
[…]
Fourthly, if there is codified knowledge in the project documents, it tends to be scattered across many documents and many projects.
[…]
Finally, many of the knowledge problems are cultural. People are incentivised to rush on to the next job rather than to spend time reflecting on lessons, no matter how important.
