Sales & Operations Planning (S&OP) is also referred to as Integrated Business Planning (IBP).
S&OP/IBP is the process that systematically integrates plans from different departments across an organization.
Sales, marketing, production, planning, procurement, logistics, HR and finance all play critical roles in an organization's success. Gaps in communication or coordination between these functions can hinder achieving business objectives.
S&OP creates aligned plans that improve cross-functional collaboration and enable the organization to respond to market dynamics faster and more effectively.
We start with a concise definition of S&OP and then go into further details.
S&OP is an integrated planning process, that balances forecasted demand and available supply, within medium-to-long term planning horizons, with a focus on competitiveness and profitability.
From that definition, the core characteristics of the S&OP process can be summarized as follows.
S&OP uses a rolling horizon of 12–18 months and is revisited on a monthly cadence.
Demand forecasts are prepared based on factors such as the economy, competition, seasonality, pricing and inflation.
Required inventory, production and procurement needs and bottlenecks are identified and alternative scenarios are analyzed to meet demand.
Stakeholders agree on a plan that balances demand and supply in line with corporate priorities.
Systematic preparations and planning activities are carried out, and decision-making meetings are held within the monthly cycle.
Enables continuous monitoring and improvement of corporate performance.
Creates the environment and capabilities for making strategic decisions or revising existing ones.
There are many factors that can disrupt the balance between demand and supply. Examples include:
S&OP helps organizations detect changes, trends, opportunities and threats, design plans to meet demand at minimum cost, and take actions by monitoring key performance indicators. In this way, S&OP boosts organizational competitiveness.
S&OP is about timely detection of market dynamics, establishing the supply capability to meet demand, and achieving these goals with maximum profitability.
S&OP is a tactical planning cycle repeated monthly. It is important to distinguish tactical S&OP planning from operational planning.
Operational planning typically covers a short horizon (weekly or daily), usually not exceeding the next 2–3 months.
Organizations must perform operational planning to keep the smooth flow of daily activities, fulfill orders, prepare semi- finished and finished goods, secure raw material supply, and so on. Operational planning typically includes order management, production planning, capacity planning, material requirements planning and detailed scheduling.
Many organizations refer to their operational planning activities as S&OP, but true S&OP extends beyond day-to-day operational planning.
Properly designed S&OP consists of tactical planning activities for a mid-to-long horizon, typically 12–18 months.
Therefore, the S&OP process should be structured to make decisions about planning issues that extend beyond operational planning.
Although practices vary from one organization to another, the following steps are generally followed:
Each step involves responsibilities for managers and staff from multiple departments and at different hierarchical levels.
The overall flow of the monthly S&OP cycle is summarized in the graphic.
The main activities in each step are summarized under the headings below. The decisions, main outputs, decision owners, and step-level indicators of each step are covered in the article Which Decision in Which Meeting in the S&OP Cycle?. It should be emphasized that each activity has substantial depth and may require significant effort.
In the first week of the monthly cycle, current sales, inventory, and capacity data is closed; product review ensures that project and portfolio plans are integrated into the corporate S&OP. Main activities:
Demand review integrates all market and demand forecasts into corporate S&OP. At this step, demand is addressed without taking the capacity constraint into account. Main activities:
Supply review integrates procurement, production, warehousing, and transportation plans into corporate S&OP. It determines which part of the demand plan can be met with current capacity, materials, and inventory targets. If there is a gap, options are prepared together with their costs; the decision is not made at this step. Main activities:
Financial review and reconciliation integrates product, demand, and supply plans with the financial plan and creates cross-functional agreement. Gaps within authority limits are closed at this step. Main activities:
The executive review evaluates the plans across functions, resolves gaps and misalignments (if any), and approves the final sales and operations plan. Main activities:
Considering the scope of the activities carried out and the impact of the decisions made,
S&OP is the modern way to manage a company in the most competitive manner.
The way S&OP should be implemented depends on a company's production strategy, product characteristics, production environment, supply chain relationships, customer demand patterns and all other factors that influence competitiveness in the market.
The stages, sequence, roles and responsibilities, analysis methods and supporting tools vary by company. How the process should be designed and operated for a specific organization must be addressed in the conceptual design phase.
