Knowledge management through multi-perspective modelling: representing and distributing organizational memory

Full and accurate representation of an organization's knowledge assets, which together constitute “organizational memory”, requires multi-perspective modelling at a number of levels of detail. We propose that the perspectives which need to be represented can be characterized as who, what, how, when, where and why knowledge; these perspectives, and necessary levels of abstraction, are captured by the Zachman framework for Information Systems Architecture. We suggest modelling techniques that might be appropriate for different perspectives and levels of abstraction, and illustrate using examples from a medical domain. We also describe how an individual perspective can become the user interface of a knowledge distribution system, and illustrate this by describing the protocol assistant, a Web-based knowledge-based system capable of representing and reasoning with best practice guidelines (“protocols”) in the medical domain.
