Comparing Conceptual Models and Data Flow Diagrams

J. Mingers

School of Industrial and Business Studies, University of Warwick, Coventry CV4 7AL.

Received 1 November 1987; In ‘Towards a tool kit for the systems analyst’, Benyon and Skidmore discuss various approaches to systems analysis and include a comparison of De Marco's data flow diagrams and Checkland's conceptual models. This note compares the two in greater detail and concludes that the underlying methodologies are much further apart than Benyon and Skidmore suggest.
