Multimethodology: Towards a Framework for Mixing Methodologies

In recent years the predilection for Systems/OR practice to be underpinned by a single methodology has been called into question, and reports on multimethodology projects are now filtering through into the literature, This paper takes a closer look at multimethodology, It outlines a number of different possibilities for combining methodologies, and considers why such a development might be desirable for more effective practice, in particular by focusing upon how it can deal more effectively with the richness of the real world and better assist through the various intervention stages, The paper outlines some of the philosophical, cultural and cognitive feasibility issues that multimethodology raises, It then describes a framework that can attend to the relative strengths of different methodologies and provide a basis for constructing multimethodology designs. Finally it presents a systematic way of decomposing methodologies to identify detachable elements, and the paper concludes by outlining aspects of an agenda for further research that emerges out of the discussion,
