The key to making people embrace PMOs is to make them love their PMO, according to this post's author, Steve Romero. And how do you make someone love the PMO? By creating a PMO that makes someone successful. This relationship, the ability of a PMO to make a person more successful (and more often) is perhaps the most tangible way to promote the PMO's use within an organization. Since PMOs can demonstrate their value (with the proper metrics recorded), it's possible to gain the support of the team, executive management, and the business as a whole.
