This study presents an interactive R-Shiny application that applies Data Envelopment Analysis (DEA) to measure and compare business efficiency. The platform incorporates directional models, orientation parameters, and alternative slack-handling strategies, enabling users to upload or filter data, compute inefficiency scores, and obtain customized targets and efficient projections. Through intuitive visualizations and dynamic benchmarking, companies can evaluate performance relative to peers of similar size or sector. The tool combines methodological advances with practical usability, offering a decision-support system that enhances strategic planning, resource optimization, and resilience. Illustrative examples demonstrate its capacity to guide companies toward improved efficiency in uncertain environments.
