The purpose of this study was to identify through the Delphi Technique, important requirements of an information system development methodology. These requirements should satisfy the needs of actual organizations, regarding the strategic use of information technology. An initial listing of requirements was developed through a review of the related literature. The Delphi panel consisted of 31 brazilian specialists in information systems. Two rounds were employed to collect from this panel the most important requirements. The requirements were distributed in five basic areas: technical process, interaction between the end user and analysts, organizational structure, business strategies and quality of the information system. It is expected that methodologies will continue to be of great importance in the development of information systems and they will increase their focus on the social-technical approach.
