Abstract

An assessment system utilizing usability engineering and six sigma. An assessment may involve task analysis incorporating process maps or the like. This analysis may be extended into a development of user interface (UI) maps. Information about customer needs may be obtained from a voice of the customer (VOC). This information may be used in a failure mode and effects analysis (FMEA) table. Usability engineering may be used to analyze usability data. Results may include usability problems and positive features enterable into the FMEA table. Usability profiles may be drawn from information and ratings in the FMEA table. A quality function deployment (QFD) may be used to prioritize usability findings with reference to the FMEA table. There may be a strengths, weaknesses, opportunities and threats (SWOT) analysis. Affinity diagrams, used to categorize information from usability profiles, the QFD, the SWOT and the FMEA table, may provide design direction for successor applications.
