- Kimberly: The goal of personal bi & ds is to give everyone an as flexible as possible access to the data they need to be able to do their job, create a report and even make strategic decisions. Or in other words we have to be business driven instead of it-driven. The bussiness should be able to get the data they need instead of creating change request for eeeevvveeeryyyy report they need. Jan: When we become more business driven, this also means that the business won’t have to wait untill IT finds a minute of spare time to handle a minor request and thus indirectly... everything will be delivered so much faster. Who here is familiar with this situation at the moment or has been in the situation that business is waiting for a minor change, while IT has no time due to major incidents or projects? So you are familiar with this situation, then you can imagine that by creating a more personal environment that there will be less administration and to be honest, less irritation and by extension ‘less’ governance. Kimberly: We will have less standardized reports and more freedom to create something that suites our own personal needs.
