This article consists of a review of the literature on the main PPM models, in addition to a critical analysis to build a theoretical framework. Four case studies are presented of companies from different sectors, which aim to identify the main PPM practices adopted, their implementation stage and the relations between those practices and the benefits obtained. The main research results show that PPM is still rarely present in organizations. The lack of PPM may be one of the factors hampering the correct implementation of strategic actions defined by the executive team. The deployment of strategic actions in projects and the structureless delegation of responsibility for implementation to mid- level managers creates unnecessary conflicts, with a consequential loss of an organization’s energy.
