The most important contribution of management in the 20th century was to increase manual worker productivity fifty-fold.  The most important contribution of management in the 21st century will be to increase  knowledge worker  productivity – hopefully by the same percentage. […]  The methods, however, are totally different from those that increased the productivity of manual workers. Peter F. Drucker, 1958

Challenge: Ease of Use (  costs!) ,[object Object]
Challenge: Scalability (quantity+time) ,[object Object],Which system would you prefer for full-text search, aggregate queries, re-use (e.g. copy&paste) ?
Challenge: Loss of Knowledge ,[object Object],[object Object],[object Object],[object Object],[object Object]
PKM OKM Degree of structuredness/ explictness/formality undetailled,  rough, brief, req. previous knowledge detailed, exact, comprehensible, shared language Recipient Me (now) Others, which I know well General public Others, no familiar with the topic Original idea: M. Boettger, 2005,  PKM and ``cues to knowledge'' Me (later) Me (2 years later) Others, familiar with the topic
Costs ,[object Object],Degree of strucuredness + formality internalisation ,[object Object],[object Object],total    there might be  a sweet spot for the total costs externalisation ,[object Object]
We need a way to quantify costs ,[object Object],[object Object],[object Object],[object Object],[object Object],Aggregate queries and semantic queries (reasoning) can retrieve more knowledge than put in!
Cost Model ,[object Object],[object Object],[object Object],[object Object]
Value Of Knowledge (Benefit) ,[object Object],[object Object],[object Object],[object Object],[object Object]
Cost Model: Externalisation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
