What approach focuses on optimizing usability methods for cost effectiveness?

The approach that focuses on optimizing usability methods for cost effectiveness is discount usability. This method emphasizes using cheaper and faster techniques to evaluate and improve usability without compromising the quality of insights gained. Discount usability aims to make usability testing accessible to a wider range of projects by reducing the costs and resources typically associated with traditional usability evaluations.

By simplifying the process and relying on fewer resources, organizations can still achieve valuable feedback that informs design decisions. This approach is particularly beneficial for projects with limited budgets or timelines, allowing teams to make informed decisions about user experience while remaining cost-effective.

Other approaches, such as iterative design, focus more on the process of continual refinement and testing based on user feedback rather than explicitly emphasizing cost effectiveness. Benchmark usability involves measuring usability against predefined standards or metrics and may not prioritize cost-saving methods. A feasibility study is concerned with assessing the practicality of a project rather than the cost-effectiveness of usability methods.
