Having worked in Business Intelligence now for over 12 years I have seen the landscape change a lot, and the technology has obviously improved.
However, the underlying needs of business users hasn’t really changed; they still want simple access to their own data.
There are all these conference of BI professionals attempting to impress each other on how evangelistic they are, and how they are embracing the cloud.
Its all just faff though, there are still far more BI projects out there that are as simple as writing a new report for a user, or adding a dimension to a cube which would save so much time.
Its the little things that make the difference in my experience.
