AT Osborne has been drawing up statements of requirements for a range of organisations for more than fifty years. Development is evolution, and statements of requirements have to evolve as well. Over the last few years, the circumstances surrounding the design and construction process have become increasingly complex. More stakeholders, different contract types and new responsibilities call for a different type of document to be drawn up than the one that was used in traditional processes. This is why we have overhauled our statement of requirements model from the ground up. We call the new iteration the ‘360 degree SOR’.
