This book presents high-quality original contributions on new software engineering models
approaches methods and tools and their evaluation in the context of defence and security
applications. In addition important business and economic aspects are discussed with a
particular focus on cost benefit analysis new business models organizational evolution and
business intelligence systems. The contents are based on presentations delivered at SEDA 2016
the 5th International Conference in Software Engineering for Defence Applications which was
held in Rome Italy in May 2016. This conference series represents a targeted response to the
growing need for research that reports and debates the practical implications of software
engineering within the defence environment and also for software performance evaluation in real
settings through controlled experiments as well as case and field studies. The book will appeal
to all with an interest in modeling managing and implementing defence-related software
development products and processes in a structured and supportable way.
