The intention with the current book has been to study the regulation, translation, and transformation of quality assurance from a number of perspectives and by different approaches. By doing so we have underlined the multifaceted nature of quality assurance and the many interests associated with the concept. Three common elements have, nevertheless, emerged from the different perspectives and approaches utilised to study and analyse quality assurance in higher education: This final chapter intends to further develop these common elements, by calling the reader’s attention to some of the most interesting ideas expressed by the authors during the 2005 Douro Seminar and that underlie all chapters in this volume. It is also our intention to go through unresolved issues and challenging questions that constitute interesting issues surrounding quality and quality assurance in higher education. We will start by reviewing the contributions to the book.
