Analyst(s): Kirk Knoernschild


In late 2010, Gartner conducted an in-depth field research project examining the software development processes organizations use to develop software systems. The research revealed that many organizations are interested in increasing their development agility, but waterfall methods still reign as the primary model for software development governance. Research Director Kirk Knoernschild explores the findings of the study in relation to the phases and gates many organizations employ to govern their software development initiatives.
