Systems analysis and design (SAND) has been the central field of research and education in the area of management information systems (MIS) or, as it is called more frequently in Europe, business informatics, almost from the time of its origins. SAND continuously attracts the attention of both academia and business. The rapid progress of information and communications technology naturally generates requirements for new generations of SAND methods, techniques and tools. Therefore, international thematic conferences and symposia have become widely accepted forums for the exchange of concepts, solutions and experiences in SAND. In particular, the Association for Information Systems (AIS) is undertaking an initiative toward SAND’s international development.

This book constitutes the proceedings of the 4th EuroSymposium on Systems Analysis and Design, SIGSAND/PLAIS 2011, held in Gda?sk, Poland, in September 2011. The objective of this symposium is to promote and develop high-quality research on all issues related to systems analysis and design (SAND). It provides a forum for SAND researchers and practitioners in Europe and beyond to interact, collaborate, and develop their field. The 9 papers were carefully reviewed and selected from 20 submissions. An additional revision took place after the conference to incorporate discussion results from the presentation. The contributions are organized into topical sections on business process modeling, integrated systems development, and software development.
