For big business the social networks provide a great resource of information that has not been available before. I heard Coca-Cola regularly mine the twitter fire hose to check what consumers are saying about their products. From this data set they are able to get a heads-up on performance that beats any internally generated data.
BI is required to transform this unstructured data into structured information that can be analysed.
BI is an opportunity if done in the right way. I've never known anything as hard as creating a multi-dimensional model but once it's there it's a gold-mine and can lead to competitive advantages if action is connected to the outcomes.
Does it change the role of the management accountant. In my case, it has been transformational. The Accounts are now 1 of many tools available. BI gives us the information/insight to support the business in a way that is more carrot than stick. BI is an enabler for business partnering.
We escaped from Excel Hell with BI. Although, with the data in the warehouse, I have seen no better client tool than Excel. With SharePoint 2010 we took the Excel reports online -only to be asked by some of the users "How can I get the report into PowerPoint/Excel”
The benefit of BI is that with the data warehouse in the back end you can have many different client tools at the front end according to what your users require.
