Cynefin Model

The Cynefin framework has 4 domains:

• Simple, in which the relationship between cause and effect is obvious to all, the approach is to Sense - Categorise - Respond and we can apply best practice.
• Complicated, in which the relationship between cause and effect requires analysis or some other form of investigation and/or the application of expert knowledge, the approach is to Sense - Analyze - Respond and we can apply good practice.
• Complex, in which the relationship between cause and effect can only be perceived in retrospect, but not in advance, the approach is to Probe - Sense - Respond and we can sense emergentpractice.
• Chaotic, in which there is no relationship between cause and effect at systems level, the approach is to Act - Sense - Respond and we can discover novel practice.

WEB 2.0 Technologies

There is no clear-cut demarcation between Web 2.0 and Web 1.0 technologies, hardware and applications. The distinction is, to a large extent, subjective. Here are a few characteristics often noted as descriptive of Web 2.0:

• blogging
• Ajax and other new technologies
• google base and other free Web- Services
• RSS-generated syndication
• Social Bookmarking
• Mash-Ups
• wikis and other collaborative applications
• Dynamic as opposed to static site content
• interactive encyclopedias and dictionaries
• ease of data creation, modification or deletion by individual users
• advanced gaming.

Critics of Web 2.0 maintain that it makes it too easy for the average person to affect online content and that, as a result, the credibility, ethics and even legality of Web content could suffer. Defenders of Web 2.0 point out that these problems have existed ever since the infancy of the medium and that the alternative -- widespread censorship based on ill-defined elitism -- would be far worse. The final judgment concerning any Web content, say the defenders, should be made by end users alone. Web 2.0 reflects evolution in that direction.

Some industry pundits are already claiming that Web 2.0 is merely a transitional phase between the early days of the World Wide Web's existence and a more established phase they're calling Web 3.0.
