Study Notes

Sales and Operations Planning: An Overview

Sales and Operations Planning (S&OP) is a collaborative process that aims to balance demand and supply by aligning operational plans with high-level business and strategic plans.
S&OP is performed periodically, either monthly or weekly, and can be implemented at different levels, such as market, regional, or global.
S&OP can lead to various benefits, including improved forecast accuracy, lower inventories, reduced operating costs, increased customer service, increased revenues, increased profits, and increased Return on Capital Employed (ROCE).
The S&OP process involves various steps, from demand planning and supply planning to executive meetings and decision-making.
S&OP occurs at multiple levels within the company, including the executive in charge of the business unit, decision president, business unit general manager, or CEO of a smaller company.
The process is typically conducted monthly, with exceptions made for major adjustments to the plan.
Key functions involved in S&OP include marketing, sales, supply planning, production, financial planning, inventory management, distribution, and purchasing.
S&OP requires a staged approach, starting with executive buy-in and establishing high-level process ownership.
Key challenges in building an S&OP plan include gaining support from the executive team, clarifying the supply chain strategy, and implementing the right technology to support the process.
Demand planning is a crucial component of S&OP and involves building a robust demand plan through adjustments to the baseline S&OP and consensus forecasting.
Time series analysis is commonly used in demand planning to project trends, account for seasonality, and estimate forecast ranges.
Forecast error metrics, such as Mean Absolute Percentage Error (MAPE) and Average Absolute Error (MAD), are used to measure forecast accuracy and bias. Human adjustments to the baseline forecast should be evaluated to determine if they add value.
