The importance of improving the quality of decisions in organizations has been a subject for several years in computer, management and decision sciences. Some results were reached, but still a lot of questions remain open. From the perspective of computer science, systems like DSS, GDSS and ODSS are examples of those results. This research proposes another approach, which is based on the concept of a post-decision phase and the technological support that could bring contributions for the decisionmaking process. Through this technological support we aim that part of the process that takes place during a post- decision implementation can contribute to improve the quality of decisions made within an organization. Some innovative aspects include the timing where it is supposed to be used, i.e., after a decision is made and also, it considers news perspectives as a combination of a flexible workflow system integrated to a knowledge repository.
