Coconuts and seeded grapes
If you can't see the picture: stop reading, you are wasting your time.
I used to do "custom bi", creating my own import programs (in a multitude of languages with more technologies than I care to recall), using Excel and print outs for analysis.
I now do Microsoft BI.
Loose analysis of Gartners quadrant should place custom BI close to coconuts (bellow to the left of the visible range) and MS BI close to the seeded grapes (moving towards peaches).
