The Mobile App Usability Inspection (MAUi) Framework as a Guide for Minimal Viable Product (MVP) Testing in Lean Development Cycle

\The Mobile App Usability Inspection (MAUi) framework is an improvised user-interface auditing technique based on the classical work of Heuristic Evaluation, pioneered by Jakob Nielsen & Rolf Molich. While the method of HE has been extensively cross-examined and reported in wide arrays of usability testing activities, its potential as a highly reliable inspection procedure is yet to be systematically formalized for lean development cycle. This paper demonstrated the application of the MAUi framework to the evaluation of a high-fidelity prototype that explored touchscreen interactions between three-dimension virtual objects on a mobile device. The initial results suggested that MAUi is a much reliable usability inspection method as the findings, given by four different inspectors shared 85% of true ability from user testing event. In addition, the MAUi framework can be used as a checklist for fine-tuning the readiness of any minimal viable products on mobile device.
