The present situation in ECBS as a whole and especially the process of software production are still characterized by heuristic and individual solutions with high costs for development and little robustness of the products. Software development and production is more understood as an art and not as a precise engineering process. As a consequence such processes often do not end with the required systems and do not produce reusable components. On the whole one observes that an accepted foundation and understanding of ECBS as a general engineering process for computer based systems (CBS) in which software production is embedded is not yet available. The IEEE TC on ECBS has been working for several years on solutions to overcome these deficits. The main goal of the work of the IEEE TC on ECBS is directed to the development and the foundation of precise frameworks which guide all engineering steps and the associated products to be produced for the life cycle of CBS.
