A Systems Thinking Approach to Domain- Driven Design

This paper builds on our earlier work in the construction of a systemic framework for developing
information systems. In this paper we apply the framework to the development of a Peer-Tutoring
System (PTS) for Introductory Programming courses in our Universities. The framework supports the
full development life cycle from business process modelling to software implementation. We use Soft
Systems Methodology (SSM) as a guiding methodology within which we have embedded a sequence of
design tasks based on the Unified Modelling Language (UML) and Domain-Driven design techniques the
Naked Objects Pattern is used as DDD approach. This leads to the implementation of a prototype
software application using the Naked Objects framework. We have involved developers and
management in reviewing the software system and the approach taken to develop it. The results suggest
that the framework can lead to improved business process modelling and software implementation.
