A methodology for business process improvement and IS development

This paper aims at discussing business process modelling and improvement as an essential work to create a successful and competitive enterprise. To achieve this goal, we use a methodology called TAD, which consists of six phases. The first three deal with business process identification, modelling and improvement. The methodology presents a new unique way for business process identification, modelling, and improvement. The last three phases continue with the implementation of the improved business process(es) by developing its information system. The business process “Surgery” is used as an example to show the implementation of the methodology.
