Abstract

Software reuse is regarded as a highly important factor in reducing development overheads for new software projects; however, much of the literature is concerned with cost and labor savings that reuse brings to industrial software development and little is known about the inherent risks associated with reuse, particularly in the case of mission and safety-critical software systems. We present the preliminary findings of a research project geared toward assessing the impact of risk in National Aeronautics and Space Administration (NASA) legacy software in flight control systems. We introduce the concept of context variables and the impact they have on reuse within these legacy systems as well as the genealogy classification models, which provide a simple, concise method of mapping reuse between families of software projects.
