Abstract
In software engineering practice, measurements may reduce development costs by improving processes and products at early stages. In model driven approaches, measurements can be conducted right from the start of a project. For UML models, a collection of metrics has been empirically validated, however, these need to be precisely defined in order to be useful. Definition of UML metrics in OCL offers a high degree of precision and portability, but due to shortcomings of this language this approach is not widespread. We propose the SQUAM framework, a tool–supported methodology to develop OCL specifications, which incorporates best practices in software development, such as libraries, testing and documentation. As a proof of concept we have developed 26 metrics for UML class diagrams in the academic context. This demonstrated the high effectiveness of our approach: quick learning, high satisfaction of developers, low imposed complexity and potential time reduction through reuse.
