Many companies are using model-based techniques to offer a competitive advantage in an increasingly globalised systems development industry. Central to model-based development is the concept of models as the basis from which systems are generated, tested, and maintained. The availability of high-quality tools and the ability to adopt and adapt them to the company practice are important qualities. Model interchange between tools becomes a major issue. Without it, there is significantly reduced flexibility and a danger of tool lock-in. We explore the use of a standardised interchange format (XMI) for increasing flexibility in a company environment. We report on a case study in which a systems development company has explored the possibility of complementing its current proprietary tools with open-source products for supporting its model-based development activities. We found that problems still exist with interchange and that the technology needs to mature before industrial-strength model interchange becomes a reality.
