Types of capacity requirements planning strategies

Capacity requirement planning strategies

What is capacity requirements planning strategy?

Capacity requirements planning strategy is the process used to find out and add the required capacity and the available resources to meet the customer demand.

Capacity requirement strategy helps manufactures to determine the number of raw materials, machines, and labor resources required for a time period to meet customer demand over products or services.

If there is a lack of capacity planning, it is difficult to meet customers’ demands, leading to losing the customer.

1. Lead strategy

This method is a belligerent approach. In this method, the manufacturer invests to increase his resource capacity before an increase in actual demand.

This strategy allows the manufacturer to get market share opposite to his competitors. The con of this method is that when the actual demand is lesser than the predetermined demand, there will be a chance of excess inventories.

2. Lag strategy

This strategy is directly opposite to lead strategy. In this type of approach, the manufacturer only adds the required capacity when the available capacity crosses its limits.

The manufacturer waits to enhance the capacity till the increase in actual demand. In this method, there is no risk of storing extra inventories.

3. Match strategy

It is the in-between strategy of lead and lag strategies. In this method, the manufacturer adjusts or boosts the capacity gradually according to the market condition.

4. Dynamic strategy

This is the safest type of approach. In this method, the manufacturer adds the capacity before it is required by analyzing the sales forecast and actual demand. Hence this strategy is accurate and less risky.
