8.2.2 Requirements and Dependability Obstacles That Must Be Overcome

Abstract

This article presents a study on the identification of the main obstacles that must be overcome in the requirements engineering phase of critical computer systems in order to ensure that these activities will help improve the system's dependability. The idea is to present how technology, process and people can interact with software and system engineering as well as the whole organization in order to fulfill the system´s mission with safety and success. Besides that, the intention is to contribute with the discussion about requirements practices in critical computer systems, particularly in the space domain, as well as helping us understand important system and software requirements engineering problems. This approach comes from the experience acquired during the development of the on-board software for the Brazilian Satellite Launch Vehicle and the study of emerging technologies in software engineering.
