This manual is an essential tool for any company - regardless of its size - to efficiently implement a sales and operations planning (S&OP) process. This management system aims to align the sales, operations, and finance departments, ensuring consistency across all areas of the organization. The book proposes a data-driven methodology, moving away from intuition-based decision-making. It provides resources for developing reliable profitability forecasts, thereby supporting the creation of consistent strategic plans and strengthening the link between the company s production capabilities and various market scenarios. Through infographics, case studies, and a self-assessment questionnaire, this guide clearly outlines each necessary step to successfully implement the S&OP process. It also highlights the importance of each phase and introduces the specific benefits of adopting this approach. By following this roadmap, any SME can benefit from the same approach used by large corporations to optimize the relationship between production and distribution channels. The goal is clear: to improve business outcomes and achieve greater efficiency.
