Microsoft BI implementation

My current assignment is implementing Microsoft BI solutions to the customer using SSAS cubes, SharePoint, Power view and Pivot tables and charts. I am very excited about this project because this project is considered as very critical for IT team to provide self service BI to the business users. Currently they are using Business Objects for their enterprise reporting and QlickView for the dashboard. Microsoft BI is going to replace these two biggies.
