Collaborative Networked Organizations represent one of the most relevant organizational paradigms in industry and services. A large number of developments in recent years have turned Collaborative Networks into a pervasive phenomenon in all socio-economic sectors.The main aim of this book is to provide a comprehensive set of reference materials derived from the results of the ECOLEAD project in one organized volume. The ECOLEAD project, a large 4-year European initiative, involved 28 organizations (from academia, research and industry), from 14 countries (in Europe and Latin America).Three main types of results from ECOLEAD are presented: (i) Conceptual frameworks and models, (ii) Methods and processes, and (iii) Software tools and systems. Furthermore, the experience and lessons learned with a number of large pilot implementations in real-world running networks of enterprises are also included as an indication of the assessment/validation of the project results.Methods and Tools for Collaborative Networked Organizations provides valuable elements for researchers and practitioners involved in the design, implementation, and management of collaborative forms in industry and services.
