Before blogs and wikis become popular among business buyers in the corporate world they will need to be positioned better as solutions. Many of the published case studies talk about how they can be used to improve group collaboration, and this is true, but it is too general.
For example, collaboration between marketing and sales could become a Sales Effectiveness solution. This is an important distinction because a busy sales organization can't be expected to buy a set of technologies like wikis and blogs and then immediately make optimal use of them. They will usually benefit from case studies and best practices and an implementation that is designed to support their specific use of the technology.
Another good example of a blog and wiki based solution is eLearning. eLearning is fairly broad area in itself but it does provide certain guidelines for how the technology should be used. For example, if a company wants to augment a formal training program with complimentary blog and wiki functionality the technology could be implemented in a way that it supports and enhances this initiative.
Corporations are still in the early stages of adopting this new technology but the early adopters have seen good results. In order for a broader group of corporate users to benefit from this technology we will need to take the next step in moving from implementing technology to implementing solutions.
