What is Backward Scheduling?
Backward scheduling is a production scheduling technique that starts with the desired delivery date or project completion date and works backward to determine the start date and sequence of tasks required to meet the deadline. It considers the lead times, production durations, and resource availability to create a realistic schedule that ensures timely delivery to customers or project completion.
Example:
ABC Electronics is a company that manufactures smartphones. They receive an order from a major retailer to deliver 5000 units of their latest smartphone model by a specific delivery date, which is Day 15.
Step 1: Desired Delivery Date (Day 15) The production scheduler at ABC Electronics starts backward scheduling from the desired delivery date, which is Day 15.
Step 2: Packaging and Shipment (Day 13 – Day 14) The first step in backward scheduling is to identify the tasks closest to the delivery date. Packaging and shipment are the final steps in the production process, and they take two days to complete. Therefore, the packaging and shipment phase must end on Day 14 to meet the delivery deadline on Day 15.
Step 3: Quality Control and Finishing (Day 10 – Day 12) Before packaging the smartphones, they must go through a quality control process to ensure they meet the company’s standards. The finishing touches, such as software updates and final testing, are also done during this phase. The estimated duration for quality control and finishing is three days, which means it must end on Day 12 to allow sufficient time for packaging and shipment.
Step 4: Smartphone Assembly (Day 6 – Day 9) The assembly of the smartphones is the next step in the production process. It takes four days to complete the assembly of 5000 units. Therefore, the assembly phase must end on Day 9 to meet the delivery deadline.
Step 5: Material Procurement and Order Processing (Day 1 – Day 5) The first step in the backward scheduling process is to procure the necessary raw materials, such as phone components and accessories. Additionally, order processing, including order confirmation and documentation, takes place during this phase. The estimated duration for material procurement and order processing is five days, and it must start on Day 1 to meet the delivery deadline on Day 15.
Start Date: Day 1 As per the backward scheduling, the estimated start date for the production process to meet the delivery deadline on Day 15 is Day 1.
Advantages of Backward Scheduling:
- Meeting Delivery Deadlines: Backward scheduling ensures that tasks are scheduled in a sequence that allows timely delivery or project completion.
- Identifying Critical Path: Backward scheduling helps in identifying critical tasks that directly impact the delivery date, allowing businesses to prioritize them for efficient execution.

In this example, backward scheduling allows ABC Electronics to plan the production of smartphones efficiently. By starting from the desired delivery date and scheduling tasks backward based on estimated durations, they can ensure timely fulfillment of the order. Backward scheduling is particularly useful when specific delivery deadlines are essential, and it helps businesses manage their production process effectively to meet customer demands and expectations.
What is Forward Scheduling?
Forward scheduling is a production scheduling technique that starts from the current date and schedules production tasks forward in time based on their estimated durations and dependencies. It is particularly useful when there are no specific delivery deadlines or when the primary focus is on maintaining a continuous flow of production.
Example: XYZ Manufacturing is a company that produces custom-made furniture. They receive an order to create a set of custom dining tables and chairs for a client. The client has not specified a specific delivery deadline but expects the order to be completed as soon as possible.
Step 1: Current Date (Day 1) The production scheduler at XYZ Manufacturing begins forward scheduling from the current date, which is Day 1.
Step 2: Order Processing and Material Procurement (Day 1 – Day 3) The first step is to process the order and procure the required raw materials, such as wood, fabric, and hardware. The estimated duration for this phase is three days, including time for order confirmation and material acquisition.
Step 3: Furniture Assembly (Day 4 – Day 7) Once the materials are available, the furniture assembly process begins. It takes four days to complete the assembly of the dining tables and chairs.
Step 4: Quality Control and Finishing (Day 8 – Day 10) After the assembly, the furniture goes through a quality control process to ensure it meets the company’s standards and the client’s specifications. The finishing touches, such as sanding and painting, are also done during this phase, which takes three days.
Step 5: Packaging and Shipment (Day 11 – Day 12) The final step is to package the furniture securely and prepare it for shipment to the client’s location. This process takes two days.
End Date: Day 12 As per the forward scheduling, the estimated end date for completing the custom dining tables and chairs order is Day 12 from the current date (Day 1).
Advantages of Forward Scheduling:
- Continuous Production Flow: Forward scheduling ensures that tasks are scheduled in a sequential manner, maintaining a steady flow of production without gaps or delays.
- Real-Time Adaptation: Since the schedule starts from the current date, it allows for quick adjustments to accommodate changes in demand, supply, or any unexpected events.
