Organisations as information systems
Organisational semiotics considers an organisation as an information system in which information is created, processed and used. The organisation as an integral system includes not only technical functions, but also human functions for information-processing and utilisation. As the semiotic framework shows, the issues at the social level are concerned with beliefs, expectations, commitments, contracts, law and culture, as well as business functions. If a technical information system is to serve the organisation well, it is crucial to understand the organisational functions at the social level. Information systems analysis and design must start with understanding and modelling the organisation. Many information systems methods provide techniques to deal with business analysis and modelling. These methods and techniques may be characterised by their different perspectives in modelling:
• the data-oriented perspective; • the process-oriented perspective; • the behaviour-oriented perspective.
