If you look at the history of Big Data requirements (volume, velocity and variety), and the NoSQL platforms supporting those requirements, you see a history of organizations and development teams breaking the mold of traditional information technology (IT) programs. Instead of following the traditional IT methodologies to solve the Big Data issues, these teams pushed the envelope and invented new technologies to solve those “volume, velocity and variety” problems. More often than not, these efforts were accomplished using collaborative, bottom-up methodologies, such as Open Source, rather than rigid, top-down approaches found in traditional product development methodologies. Specifically, if you look at the history of the Hadoop development at Yahoo, you see an approach that sought the input and wide spread resources of the Open Source movement rather than a more rigid proprietary approach.
