Towards strategy patterns for evaluating usability

Abstract

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 higherlevel 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.
