One of the most important elements in decision-making is the availability of information which is used in the management of organizations. In this paper, we present the method SIMBIOSIS (System of Indicators for Managing Business Intelligence Oriented Strategic Information System). This method considers the two basic levels of decision-making in organizations; these levels are named strategic and tactical. In addition, the method looks at the minimal business intelligence objective of providing the right information to the right person at the right time as a variable. The conjugation of these two points of view permits us to generate a set of indicators. Using these indicators, with a system of information status identification we have proposed, help in the tagging of each component. The information analyzed by these indicators and the status identifiers provide the organization with an extended view of an information system that can aptly be adapted into business intelligence solutions. This also allows a vision of not only the organization but also the extended organization (i.e. organization that includes its environment).
