This paper presents the basic principles of the Systems Engineering Effectiveness Research Institute’s (SEERI) Software Engineering Effectiveness Model (SEEM), which enhances many current development processes. SEEM enables integration of all aspects of development into a single streamlined workflow. SEEM also includes a system-wide iterative model that ensures meaningful oversight of artifact evolution across the product lifecycle, thus guaranteeing the relevance and currency of workflow artifacts. SEEM handles the unique challenges of embedded systems, such as immature tools, high-availability, and hardware dependencies. In addition, SEEM strives to minimize process overhead and incorporate as much of an enterprise’s current processes as practical.
