Innovation, however, is a contested term (Johannessen, Olsen and Lumpkin 2001; Wolff 2008). ‘New process’ or ‘new product or service’ (Clegg, Kornberger and Pitsis 2008, 374); ‘an idea, practice, or object that is perceived as new’ (Rogers 2003, 12); ‘planned or deliberate changes’ (Hannan and Silver 2000, 10) all define innovative practice. With such a plethora of definitions, the term ‘innovation’ is a problematic starting point for analysis as there is no shared understanding of the boundary of the concept. p. 428
