ABSTRACT
Doctrine: a set of guiding principles, carried into effective structures and roles, is a powerful tool for shaping what we aim to do, influencing how we perceive our tasks and guiding us as we fill our toolkits. Doctrine is not dogma, it is guidance and not rules, and one who designs or one who implements doctrine is not a doctrinaire. Doctrine is at best permissive, not restrictive: it should tell us not what we may not do, rather doctrine should guide us as to how we might do what we want or need to do. Doctrine is where principles and practice meet, and it is also where academics and practitioners meet – or they should.
