From plan to realisation (intention to action) Many plans are never implemented Everybody is “busy, …. ” “No time for innovation” Decreasing craftsmanship (more information, less knowledge) For innovations like this, the organisation of knowledge is the most essential challenge…
Explicit knowledge Methodology? Implicit knowledge (tacit)
Three propositions 1. The complexity of water projects increases 2. For coping with complexity tacit knowledge is crucial 3. Tacit knowledge decreases YES YES Problem +
Five Spheres “We have to avoid risks: kill the project” “For efficiency we need facts and figures” “We need data, to optimise the system” “They do not understand us” “We have to apply an interactive approach” “It is impossible to maintain decentralised facilities”
Tacit Knowledge You will find tacit knowledge in all five Spheres The Spheres are drifting apart… people are not talking each others’ language As a result, tacit knowledge is getting isolated in the Spheres (there is no flow anymore) Conceptual Models are not effective when there is no flow of tacit knowledge
Next step We think it would be interesting to do the same research in other countries (FP 7, Interreg? ) Also: work out strategies to increase the flow of tacit knowledge in complex urban water issues Testing concepts in the Netherlands already started: 21 st Century Guilds and Workshops (re-introducing Master – Journeyman – Apprentice relationships)
st 21 Century Guilds: Workshops Organised around concrete – practical – urban water issues All Spheres included Narrative approach Resulting in Speech Act (debate → intention → action) Logos, Pathos & Ethos
New Research… Teams of technical and social scientists Looking at differences between the countries involved Organising several Workshops including all Spheres Work on a common strategy to stimulate tacit knowledge flow Who is interested?
My personal ambition 13 ICUD: presenting the results of ten Workshops in the Netherlands; 13 ICUD: two 21 st Century Guilds: on sewer systems and on dykes; 14 ICUD: presenting the results of many Workshops in many countries; 14 ICUD: one international Guild on the urban water cycle (energy, nutrients, etc. )
Thanks for your attention …
