The reclamation and redevelopment of software “brownfield sites” requires a multi-layered understanding of the domain in which the enterprise system lives. A further dimension is added to the interconnectivity of the domain knowledge when the evolution of the system requires the migration of existing services to a web-based system and the creation of new value-added services. Where the enterprise systems are both internal to the organisations and “joined up” into wider inter-organisational networks, there are further challenges to developers. The Institutionally Secure Integrated Data Environment project is addressing the problems and issues surrounding the development and delivery of web based services for “joined up” systems within Higher Education Institutions. In this paper we define the meta-process that has emerged as a way to support incremental implementation of value-added services together with the relationships that exist amongst the generated work products in context with the meta-process.
