"Erik Hollnagel has always been ahead of the curve, and here he is again. A book about safety without the s-word--only to replace it with another s-word! Synesis not only unifies everything relevant about organizational performance, it sums up Erik's decades of remarkable, substantive contributions to our field."- Prof. Sidney W. A. Dekker. Griffith University, Brisbane, Australia "Some people are lumpers, trying to build a world of high-level categories. Others are splitters, seeing fine-grained detail and multiple types wherever they look.

Few of us can be both, but as with everything he does, Erik Hollnagel shows he can. Synesis integrates huge amounts of detail about organisational life without losing the particulars. It's an idea destined to become widely used, like so many of his contributions." - Prof. Jeffrey Braithwaite, Macquarie University, Sydney, Australia "If we take seriously a 21st century truism that change never starts because it never stops, a book that makes change challenges more comprehensible and change processes more manageable cannot be timelier or more important. Synesis is an invaluable must read for those seeking to change organizational systems through a pragmatic blend of theory and practice." - Kathleen M. Sutcliffe Bloomberg Distinguished Professor Johns Hopkins University, Baltimore, Maryland, USA "This thought-provoking book challenges the long-held beliefs that problems in productivity, quality, safety and reliability of production systems can be solved in isolation, each with its own special measures.

It argues that problems in production systems are due to feeble human efforts to get the system working rather than to random cause and that a less fragmented mindset therefore is required. I recommend this book for all interested in the improvement of productivity, quality, reliability and safety in practice as well as in theory."- Bo Bergman, Professor Emeritus, Quality Sciences, Chalmers, Sweden.
