ABSTRACT
Enhancement is broadly defined, capable of operating at any scale. It can involve doing things better or doing things differently. A systematic approach to enhancement might be visualised as a succession of feedback, evaluation and action loops or ‘helixical’ processes. A sophisticated model might capture different scales of feedback, evaluation and action, across different settings or environments, into a multidimensional model. A constant challenge is to ensure that approaches to enhancing quality maintain a balance between the competing demands of stakeholder (self-)interests.
