A Methodology for Designing Information Systems based on Situational Theories of Agency. Information systems (IS) are part of work systems that are goal-directed. Existing methodologies for designing IS implicitly assume that goal-directed behaviour is enabled by deliberation upon abstract models (the 'thinker' metaphor). Recent work in robotics and artificial intelligence has tested an alternative theory of goal-directed behaviour that emphasises reactive responses to situations (the 'routine' ....A Methodology for Designing Information Systems based on Situational Theories of Agency. Information systems (IS) are part of work systems that are goal-directed. Existing methodologies for designing IS implicitly assume that goal-directed behaviour is enabled by deliberation upon abstract models (the 'thinker' metaphor). Recent work in robotics and artificial intelligence has tested an alternative theory of goal-directed behaviour that emphasises reactive responses to situations (the 'routine' metaphor). We will refine and test a new IS design methodology based on this situational theory and show that it can produce effective IS designs, applicable to time-constrained routine operational domains, which are radically different from those produced using existing methodologies.Read moreRead less
