The strategy concept has changed dramatically: from a long range planning to strategic planning then to strategic responsiveness. This response implies moving from a concept of change to a concept of continuous evolution. In this context, the competitive intelligence system aims to improve decision-making in all aspects in business life, particularly offensive and innovative decisions. In this paper, we present XPLOR, our competitive intelligence system based on a multidimensional analysis model. The objective of this system is to analyze the information environment in all dimensions of a decision problem, with the exploitation of information by analyzing the evolution of their interactions.
