Towards Strategy Patterns for Evaluating Usability

In this paper, we propose a holistic quality evaluation approach for usability and user experience (UX), which relies on quality views and strategy patterns. A quality view relates accordingly an entity super-category, e.g., product, system, system in use, with a quality focus such as internal quality (IQ), external quality (EQ), and quality in use (QinU). Usability and UX are higher-level characteristics that should be linked to quality views appropriately. Also quality views support ‘influences’ and ‘depends on’ relationships. With a concrete evaluation or improvement project goal, our approach selects and instantiates a suitable strategy from a set of strategy patterns.
