This work attempts to give a new direction to the analysis and design of Business Information Systems by substituting traditional techniques with more participatory techniques based on cooperation. In order to attain this objective, a review of organisational structures is suggested, as well as the use of cooperative methodology for the development of Information Systems. Equally, we propose the design and implementation of a set of cooperative tools which are characterised by an interface that allows end-user participation in the new phases of system creation.
