The strengths of product line engineering have been described before. But how can an organization make the move from developing one-of products to product line engineering without major interruptions in the day-today work? This paper describes how to perform the transition to product line engineering and lists the various strategies for such a transition.(More)
Software product lines promise benefits like development and maintenance effort reduction, time to market decrease, and quality improvement, all resulting from planned and systematic reuse of common core assets. However, very little quantitative data has been measured so far to prove these promises. This paper formulates and discusses 7 hypotheses on how(More)
The NASA Goddard Space Flight Center is developing a guidance , navigation, and control flight software product line that includes both processes and their accompanying products. The processes include a domain and application engineering process that have been influenced by Synthesis[1] and FAST[2]. The products include graphical and textual analysis/design(More)
The goal of this study was to create a heat map indicating the probabilistic location of major ganglia of the cervical sympathetic trunk (CST). Detailed dissections of human cadaveric specimens, followed by spatial registration and analysis of the cervical sympathetic ganglia in the neck and upper thorax regions (C1-T1) were performed in 104 neck specimens(More)
OCTOBER 1993 iii FOREWORD The Software Engineering Laboratory (SEL) is an organization sponsored by the National Aeronautics and Space Administration/Goddard Space Flight Center (NASA/GSFC) and created to investigate the effectiveness of software engineering technologies when applied to the development of applications software. The SEL was created in 1976(More)
