After an initial exploration of the systems life-cycle, which identifies the key stages in any methodology, the paper proceeds to examine the nature and role of information systems methodologies. An object-oriented methodology is introduced as a preliminary to the consideration of methodologies for multimedia graphical user interfaces. Comparisons between the stages in some of these methodologies yield an identification of key features for methodologies in the development of public access systems. The concept of the informed health-care 'consumer' rests on the availability of comprehensible information. While various bodies have made information available, its quality is mixed.
Information is sometimes untrustworthy, incomprehensible, or simply forgotten by patients.
An understandable record of advice is more likely to bring about compliance with treatment and lessen the need to revisit the surgery. Presentation, reading ease and understanding were considered. The goal of making health-care information comprehensible was achieved. Guidelines for revising such material are described and illustrated. The informed consumer goal may be achievable if writers of health-care information attend to communication as much as to the adequacy of their medical advice.
