This festschrift volume, published in honor of Manfred Nagl on the occasion of his 65th birthday, contains 30 refereed contributions, edited by five of his academic descendants. The types of papers vary significantly, including classic research papers in the style of journal articles, surveys of focused research areas, essays reflecting on certain research topics, and papers summarizing long-term work conducted by Manfred Nagl. The volume is structured in five parts: graph transformations, software architectures and reengineering, process support, embedded systems engineering as well as engineering design applications.

Manfred Nagl has been a very active, productive researcher with great impact in a number of different areas, e.g., graph transformations and their applications to a wide range of disciplines, software engineering environments, engineering design processes, and software architectures.We—five of his numerous academic descendants — were influenced deeply by Manfred’s work. For this reason, we decided to prepare this volume, which was edited in his honor on the occasion of his 65th birthday. A “pre-release” (book of abstracts) was presented to Manfred at a celebration at RWTH Aachen University in June 2009. The complete volume followed when Manfred received an honorary doctorate from the University of Paderborn in November 2010.
