Should I shave it off or not? Should I keep the beard or loose it? Voting is now open on linkedin: (http://polls.linkedin.com/p/63040/xcgat). Extensive Data Analysis  reveals that younger people and females say SAVE IT.  However Older people and men say SHAVE IT. So the question now is which group to focus on? For now I have decided to keep it at least until thursday (Nationale BI Event in Leiden).

PLEASE NOTE: THIS IS WRITTEN WITH SANDER HOOGENDOORN - PRINCIPTAL TECHNOLOGY OFFICER AND AGILE EVANGELIST @ CAPGEMINI.

I was asked the question: “Is Agile the correct development method for Business Intelligence?”.  An interesting question. According to me any development method that takes BI characteristics in mind is better than a method that does not. Therefore I would say that Agile is better than most waterfall based methods.

So, what are some of the BI characteristics that we have to take in account while using any development method? First , BI projects almost always have some sort of business purpose. For example, sales insight or call center performance improvement. But the business case is not always clear upfront. So the BI contribution to the bottom line is often unknown as well. Another thing is that the business requirements are also often not very precise. At the start of any BI project getting the detailed and finalized requirements from future information product users is a challenge at best. Finally, the whole development process is pretty much linear. We get data from the source, we ETL it to our warehouse, fill the data model, ETL it to our data marts and build the reports. So before any user sees the final result 80% of the work is already done. The biggest challenge for BI development methods is to deal with the ‘advancing understanding’.

Agile can contribute to this as it works with: small iterations, used cases, fast and frequent releases, much interaction with the client, integration of testing in the development cycle and so on.

The key question that remains: “Are agile methods being adopted and used in the BI world?”. The answer to that is very simple: Agile is all in the mind. The question is not if Agile CAN be used, the question is if BI people WANT to use it. 

Last week at the Butler BI event in the Netherlands, Timo Elliot from SAP BOBJ, gave a presentation. The cool thing was that his presentation featured live tweets. He integrated Twitter in the Powerpoint presentation. This opens up all kind of possibilities: remarks, voting … Check out his website and download the tool. I love this kind of innovative features. http://www.sapweb20.com/blog/2009/10/web-20-presentation-tools-from-sap-integrate-twitter-into-powerpoint/comment-page-1/#comment-272
