This document discusses the relationship between enterprise architecture (EA) and project and portfolio management (PPM). It argues that EA and PPM have different but complementary perspectives in helping an organization translate strategy into realized value through portfolios and projects. The document provides examples of how EA and PPM can collaborate more effectively by having EA guide the enterprise towards its target state while PPM drives the enterprise strategically forward. It also provides a sample collaboration model where EA and the project manager work together on project architecture.
