User-centered design and evaluation process of an existing data integration and visualization platform in accordance with the ISO 9241–210 standard. The iterative design and evaluation cycle is broken down into phases with the related ISO 9241–210 standard’s phases in parenthesis. The cycle was carried out once with each phase described for the design/evaluation of data integration and visualization software for intensive care monitoring and decision-making. Phase 1 was an initial phase where the user-centered design process was identified and work included gathering existing studies in the form of a systematic review. Phase 2 included both unit-level observations and clinician-level interviews to gather information about intensive care work using continuous data. Phase 3 was a heuristic assessment of the software to determine usability issues that violate accepted interface design principles and to suggest design solutions. Phase 4 was a usability test method where issues were identified by actual users performing true-to-work tasks and recommendations for design solutions were provided. Results from this last phase are presented here
