IS Development Methodologies
IS Development Methodologies contain models and reflect particular perspectives of ‘reality’ based on a set of philosophical paradigms. A methodology should tell you ‘what’ steps to take and ‘how’ to perform those steps but most importantly the reasons ‘why’ those steps should be taken, in that particular order.
