User experience of agile project: I have never known a project to develop at such a rate."

To some, the appearance of the Rational Unified Process (the RUP) in this list of Agile processes will seem odd, if not incorrect.

At its core, however, the RUP is Agile, and the spirit of the RUP is very much Agile. Regardless of any particular configuration, it is intended that it should be iterative and low ceremony. The most common fault when implementing the RUP, though, is failing to accept the required mind-set change to embrace the iterative approach, instead mapping the phases to create what is essentially a more traditional, waterfall approach.
IndigoBlue has a long held view that incremental delivery, and the supporting incremental strategy, is core to the success of Agile management. This tenet is the basis for our governance framework and our approach to managing Agile at scale. Last week I was presented with an illustration of this in the shape of one of our customers that has recently piloted the use of Agile in their office in the States.
