"In fact, most organizations don't do this for such initiatives and, in some cases, a less detailed business case is more appropriate." For initiatives that do require a detailed financial case, Gartner has developed an eight-step process built on the Gartner Business Value Model (GBVM).
The GBVM identifies the most frequently used business performance indicators and links them directly to financial outcomes.
The challenge in this part of the process is to align the objectives typically associated with a collaboration and social software initiative - such as improving internal communications, enhancing teamwork and improving knowledge capture and reuse - with relevant business areas and business performance metrics from the GBVM. Existing metrics can be used if an organization already measures similar business metrics to those in the GBVM, or new ones can be introduced if none of the metrics in the value model are appropriate.
