SQL Server 2012 Data Warehousing Overall Flow
Not 100% what you are getting at, whether you're talking about the order of developing a data warehouse or how the data flows into the warehouse and on to other things.

There is a camp that models all the data into the data warehouse (using dimensional modeling techniques, and only generally informed by the users roles and domain expertise) and then the end users build their analytics on it.

There is another camp that gathers end-user requirements and then builds the warehouse to meet that, identifying the data in the source system.

I tend to be more in the first camp, because users only know what they want once they play with the data and see what's available.
