In the field of emergency response and crisis management, staff work is a tried and tested, but as yet little studied, method of dealing effectively with complex situations. The author considers the entirety of the processes involved in different types of staff groups & ranging from technical and specific performance capacity using the necessary tools and forms of behaviour, to ways of verifying the results achieved. The tools that are needed for successful staff work and that have been developed by the author specifically for staff work are of central importance. Practical applications of the tools presented are illustrated in tutorial videos produced especially for this book.
