Step 1: S&OP Portfolio Planning - What do you plan to sell
Step 2: S&OP Demand Planning - How much do plan to sell ?
Step 3: S&OP Supply Planning - How will you supply the planned sale ?
Step 4: S&OP Optimisation - Balancing Sales and Supply
Step 5: S&OP Executive approval
Step 1: S&OP Portfolio Planning - What do you plan to sell
The S&OP process needs to be based on an accurate reflection of the company’s product portfolio. Each month, as the first step in the S&OP process, the portfolio should be reviewed with the aim of flagging new product introduction, identifying delist requirements, adding new SKUs and updating ABC classifications. The reviewed and validated portfolio can then be used as the foundation for the next step, Demand Planning.
Step 2: S&OP Demand Planning - How much do plan to sell ?
In this step the unconstrained demand forecast is developed and agreed. This is where the long-term sales forecast is updated, including baseline growth or contraction, new product impacts, market promotions and extrinsic trends. For a truly effective S&OP process this demand plan should focus on a mid-to-long term horizon, usually at least a rolling 18 months at an aggregate level i.e. product families.
The longer the planning horizon, the better it is for the supply chain. New assets such as warehouses and production facilities can have a long commissioning lead time: A S&OP process looking at just 6 months is of little use if it takes 12 months to commission new assets.
Step 3: S&OP Supply Planning - How will you supply the planned sale ?
Using the information from Step 2 the operations team now review how they will meet the required demand plan and what level of resource will be required. These resources may include people, handling equipment, material, production equipment, warehouse capacity and transport capacity. If there is significant growth in the Demand Plan from Step 2, then the Supply Planning Step can require a significant level of operational modelling.
Of course, it’s relatively easy to be reactive with resources in supply chain. Temporary labour, vehicle spot-hire and 3rd party storage can all be deployed quickly as a contingency measure, but at an additional, and usually unbudgeted, cost. Instead, given the opportunity to plan for events through an S&OP process, the supply chain and operations teams are able to ensure that fluctuations in demand are more efficiently planned for.

Step 4: S&OP Optimisation - Balancing Sales and Supply
In Step 4 the key stakeholders involved in the first three steps meet to discuss the outputs of their respective steps and agree the ‘non-negotiable’ elements alongside the trade-offs. For example, the demand plan may reflect a sales forecast that will exceed production capacity for a short period of time. In the Supply Plan this sales requirement may have been met by using overtime, or external production capacity at additional cost. However, it may be agreed during this optimisation step that the forecast can be met by pre-building inventory in a quieter period and hence the requirement can be met at a more favourable supply cost.
Step 5: S&OP Executive approval
Step 5 is the opportunity for the company’s executive team to review the plans from the preceding steps and provide decisions where required. This may encompass reviewing the Demand Plan to ensure it fits with the business strategy and authorising requirements within the Supply Plan that may incur additional costs i.e. new equipment, premises, inventory, outsourcing capacity etc.
Any changes or decision made at the Executive approval stage are then fed back to all stakeholders and incorporated within the planning of the next S&OP cycle.
