This conclusion presents some closing thoughts on the key concepts discussed in the preceding chapters of this book. The book explores different industry sectors where integrating information across organisational boundaries and software domains can help improve the management of human, economic and ecological resources. It highlights some contrasting aspects of integrated information systems and processes that need to be considered if we are to achieve this objective. The book describes a new quality assurance system which was designed in Denmark as a project delivery strategy to handle information integration across life-cycle phases and between service providers and public client organisations. It proposes more integrated systems that allow government and industry knowledge, information and data to be linked and used in connected way can help deliver a more sustainable and productive social housing sector. The book shows that the performance of the final product is often dependent on both end-user and staff behaviour and understanding of the system itself.
