Project portfolio management (PPM) is a recognized best practice for increasing businesses' return on their IT spend. With their in-depth understanding of the firm's operating model and their ability to convert strategies into actionable steps, business architects hold a special key that can unlock the door to improved results from the IT project investment portfolio. Such insights are essential for organizations to mature their PPM processes. Although some firms have realized this, it's still rare to see the project management office (PMO) and business architects working closely together. EA leaders should view this nascent collaboration as an opportunity to elevate IT's ability to support the business.
