I was reviewing an enterprise wiki implementation recently. This is a group that had impact across the organization on multiple divisions. The wiki was great. The customizations were great. But the people aspect had the 1.0 hangover. Only members of this group had access to the wiki while the implications of the knowledge that gets created was enterprise wide . This seems to be a common problem in many organizations experimenting with Enterprise 2.0. Its not about deploying tools; its about breaking silos and allowing a “true” read-write web to emerge. Groups that are primarily considered to be knowledge consumers need to be included in the new web of participation for true value to emerge. Enterprise 2.0 ecosystems , though bottom-up could still create silos of knowledge unless we proactively evangelize the fact that knowledge consumers are also knowledge producers. In a typical software company this could mean that a Wiki that the Quality group sets up needs to be open to the delivery teams for true knowldge churn to happen. Otherwise we have a new silo,accerlated by Enterprise 2.0 tools.
