Current methodologies for evaluating badminton footwork predominantly rely on non-digital approaches, producing subjective assessments with constrained precision and accuracy. To address this limitation through a needs-driven approach, the authors developed a sensor-based instrument, incorporating advanced digital data collection techniques for precise and objective performance measurement. The reliability and practicality of this instrument require further testing for optimal utilization. The research aims to develop a reliable and practical assessment tool for evaluating badminton footwork capabilities. This study employs the Research and Development (R&D) methodology with an experimental approach. The development process follows the Borg and Gall model, which encompasses ten stages within product development. The sample population comprises badminton athletes from West Sumatra. The validity of the research instrument is established through construct validation conducted by qualified experts, including information technology specialists, test and measurement professionals, and badminton practitioners. Reliability is assessed through testing and retesting procedures to determine the consistency of the instrument. The results demonstrate high reliability, with reliability coefficients of 0.970 in small group testing and 0.961 in large group testing. These findings confirm that the digital badminton footwork measurement device developed is highly accurate and suitable for use in assessing badminton footwork skills.
