Producing useful and usable software often requires continuous and iterative evaluation. This paper introduces a novel usability evaluation method based on the Cognitive Dimensions of Notations framework. The target of our evaluation is Herbal a suite of tools designed to simplify agent development by providing a high-level language and maintenance-oriented development environment. The method introduced here uncovers dimensions of concern, which are used to measure the usability of Herbal and to identify areas for improvement in the design. In this article, we demonstrate how we used dimensions of concern to effectively evaluate and improve usability, and we discuss ways in which our method can be adapted, extended, and applied to improving the usability of other interactive systems.
