When we are invited to speak to a client about the effectiveness and results of Scrum at the outset, we are regularly asked about other agile methods. We refer to a Gartner study which, in our experience, is still very relevant.
Analysts from the Best Quality Institute (BQI) have compared the most important methods of agile software development. In its 2009/2010 ‘Hype Cycle for Application Development’, Gartner categorised agile methods with the maturity level ‘Early Mainstream’. According to the analysts, it should take around five to ten years from this point until the ‘Plateau of Productivity’ is reached and agile methods are widely accepted. However, the market researchers are not always in agreement, because according to an analysis by Forrester, agile software development processes are already considered established.
