Enterprise Architecture (EA) is a tool that captures what is essential to business, Information Technology and its evolution. It focuses on the relationship between business processes, information sharing and technology infrastructures within an organization. With this, the need to align and evaluate, through strategy and objectives, strategic planning of organizations in the EA with the implementation of project portfolio is a complex challenge. Thus, in this research, we survey and apply metrics, patterns, and principles of the EA, as well as heuristics. All of them enable the measurement of quality attributes in the EA to which it must respond to be accepted. This article proposes an approach that allow the evaluation of the alignment between the portfolio and the strategy in the context of EA, within an organization, through a library of heuristics, created in ArchiMate. The proposed solution will be demonstrated when applied to a government organization.
