The competitive pressures of the telecoms sector are leading to a major push towards the automation and integration of many operational support processes. This creates pressures to develop more flexible and thus durable operational support systems within reduced system development time-scales. To respond effectively to these pressures, developers need to maximise software reuse and make effective use of modern software engineering tools and techniques. This paper presents an approach to modelling reusable components for telecoms management using the Unified Modelling Language. This approach aims to facilitate the selection of components and their rapid augmentation to meet management system requirements. The approach uses the concept of component façades, which are generated using CASE tools and published on the Web.
