The goal of this workshop is to bring together researchers and practitioners from the HCI and SE fields to determine the state-of-the-art in the interplay between usability evaluation and software development and to generate ideas for new and improved relations between these activities. The aim is to base the determination of the current state on empirical studies. Presentations of new ideas on how to improve the interplay between HCI & SE to the design of usable software systems should also be based on empirical studies. Within this focus, topics of discussion include, but are not limited to:

• Which artifacts of software development are useful as the basis for usability evaluations?
   
• How do the specific artifacts obtained during software development influence the techniques that are relevant for the usability evaluation?
   
• In which forms are the results of usability evaluations supplied back into software development (including the UI design)?
   
• What are the characteristics of usability evaluation results that are needed in software development?
   
• Do existing usability evaluation methods deliver the results that are needed in user interface design?
   
• How can usability evaluation be integrated more directly in user interface design?
   
• How can usability evaluation methods be applied in emerging techniques for user interface design?
   
• How can usability evaluation methods be integrated to novel approaches for software development (e.g., model-driven development, agile development).
