Track: Supply Chain Management

Abstract

Optimize inventory level, reduce the discrepancies in supply and demand and increase customer satisfaction are the most decisive key factors that impact significantly the overall performance and effectiveness of the firm. In this context, the concept of sales and operations planning (S&OP) was developed with the aim of supporting companies to improve their process, ensure operational flexibility and gain competitive advantage. This paper is intended to present a literature review of sales and operations planning covering the various maturity models developed in this field .A case study was included for the evaluation of S&OP process maturity in automotive manufacturing company using two selected models proposed by Grimson & Pyke (2007) and Wagner et al. (2014). The implementation of S&OP process in the studied company shows significant improvement in supply chain performance, resulted in a 17% improvement in forecast accuracy, 37.5% reduction in leftover stock and 17% improvement in delivery performance. In the last section, some gaps were identified and proposal for improvement was presented in order to advance the company maturity stage. The results of this study can be considered as a way to understand the different aspects of S&OP maturity models and provide guidance for researchers and practitioners in identifying gaps and opportunities for future research.
