Denham Grey reflects upon his company's use of wiki and KM:
Reflecting in the role of a Wiki in KM I see the major benefits as:* Easy way to get folks publishing on the web (3 minutes!) rather like blogs
* A great environment for collaborative writing
* Space for capturing and refining patterns - proven solutions to repetitive issues
* Wiki is good for dialog, annotation, annealing and refactoring - all important ways to engage with text
* Emerging tool for capturing corporate memory, e.g. we are using a Bliki combo Wiki / Blog to gather process stories, record subtle changes in equipment parameters, track the rationale for test batches and gather customer innovations at our helpdesk
Its important to note that the above activities build corporate memory not from side-activities, but simply doing your work within the right kind of shared space.
He also notes a business school using a wiki for surveys. I'd suggest the benefit of doing so compared to forms is it allows survey participants to provide greater qualitative insight and stories in the process.
