This book constitutes the proceedings of the 6th Enterprise Engineering Working Conference (EEWC), held in Funchal, Madeira Island, Portugal, on May 30 - June 3, 2016. EEWC aims at addressing the challenges that modern and complex enterprises are facing in a rapidly changing world. The participants of the working conference share a belief that dealing with these challenges requires rigorous and scientific solutions, focusing on the design and engineering of enterprises. The goal of EEWC is to stimulate interaction between the different stakeholders, scientists as well as practitioners, interested in making Enterprise Engineering a reality. 



The 12 full papers presented were carefully reviewed and selected out of 34 submissions. The topics of the presented papers allowed for active participation in interesting discussions and exchange of ideas and stimulated future cooperation among the participants. This made EEWC a real working conference contributing to the further development of Enterprise Engineering as a mature discipline. Topics covered include: Organization Implementation; Value and Co-Creation; Evolvability; Modelling, Patterns and Viability; and Foundations of Enterprise Engineering.
