2 IS33 ISD - theories, methods & techniques2 Week 4 (1) 2008 The Socio-Technical Philosophy Introduced in 1940s by the Tavistock Institute (London), Acknowledged 2 things: The significance of the social system (i.e. people) The difference between the social system and the technical system Key principles for design Joint optimisation of technical & social system Semi-autonomous work groups Participation Quality of work life

4 IS33 ISD - theories, methods & techniques4 Week 4 (1) S-T principles for good design – by Tavistock Institute of Human Relations 1. Compatibility 2. Minimal critical specification 3. The sociotechnical criterion 4. Multi-function 5. Boundary location 6. Information flow 7. Support congruence 8. Design and human values 9. Incompletion Source: Mumford, E (1987)

5 IS33 ISD - theories, methods & techniques5 Week 4 (1) 2008 Critiques of S-T

6 IS33 ISD - theories, methods & techniques6 Week 4 (1) 2008 ETHICS One of best known methodologies in S-T = Effective Technical and Human Implementation of Computer-based Systems Enid Mumford has put her book on Designing Human Systems – the ETHICS Approach (1983) online at

7 IS33 ISD - theories, methods & techniques7 Week 4 (1) 2008 Main strands in ETHICS Job satisfaction – good fit between employees needs and what the job offers (in terms of knowledge, psychological, efficiency, task-structure, ethical) Development of IS is a change process and will involve a process of negotiation between the affected and interested parties. Hence participation is vital, users can make decisions on how the use of technology might improve their job satisfaction – use of steering committee and design group(s) Source: Avison and Fitzgerald
