This work presents an application of adaptive technology to the decision making process applied in the business management and Decision Support Systems. To accomplish this goal, a development environment based on adaptive decision tables is proposed. This way, a user who is not familiar to the computing concepts, but that does know the decision making process and the use of decision tables, can understand, change and even develop applications in this environment. The main results obtained from this study were the implementation of adaptive devices, specifically the adaptive decision tables, in functional languages, and the definition of an input language to the development environment proposed, that can be classified as a domain specific language.
