The S&OP process, like any business process of strategic or tactical level, requires having its performance measured so that, through the monitoring of these measurements, improvement actions for the factors affecting their performance can be created. The models for performance analysis in the literature failed to identify the most relevant causes of inefficiency to the process and do provide a way of measuring the process performance. Therefore, this paper presents a proposal for a quantitative model for the analysis and performance improvement of the S&OP process based on the diagnosis and reduction of its most important inefficiencies.
