In the early days of its adoption, the Agile methodology seemed to be diametrically opposed to the process-driven project management office (PMO), which most often corresponded to a Waterfall-style planning and delivery methodology. Agile was a more nimble approach to project management while Waterfall stipulated a rigid, document-driven structure. The same is true today, but in the past few years, a growing partnership between Agile practitioners and the PMO has emerged. The two are no longer mutually exclusive. In fact, the discipline of project management has evolved to actively include both methodologies in the enterprise.
