One of the key questions of companies who are looking to implement Enterprise 2.0 Software is about the ROI and how to measure it. This question is as important as it is difficult to answer, as it raises the following issues:

• What to do if there are not enough ratios, experiences and case studies?
• How to measure the quality and the effect of communication, collaboration and knowledge management?
• What is the impact of Enterprise 2.0 Software on a specific corporate culture?

These questions are not easy to answer. Therefore, we have collected some interesting approaches in the following list.
This list is not exhaustive, but it shows the great variety of different approaches and opinions.
