Groupware is evolutionary and difficult to develop and maintain. Thus, its code becomes unstructured and difficult to evolve. In this thesis, a groupware development approach based on components organized according to the 3C collaboration model is proposed. In this model, collaboration is analyzed based on communication, coordination and cooperation. Collaboration necessities of the group, analyzed based on the 3C model, are mapped to software components, also organized according to the model, in order to compose the system. The proposed approach is applied as a case study to the development of the new version of the AulaNet environment. The environment´s code currently suffers the mentioned problems. In order to instantiate the communication services of the environment, for the case study, 3C based component kits were developed. The components allow the composition, re-composition and customization of the services in order to reflect collaboration dynamics changes.
