Backward vs. Forward Scheduling: Contrasts, Advantages, Disadvantages

Effortlessly organize your delivery drivers and schedules with eLogii's optimization software.

In essence, backward scheduling involves planning from a desired completion date.

It helps determine the duration of each production stage and calculate the earliest start date for production.

On the other hand, forward scheduling begins from the start date or the receipt of the production order.

In this project scheduling method, you begin planning and start production right after setting the start date.

However, these are just basic descriptions.

This article will explore these two scheduling systems in more detail. We'll discuss the factors to consider when deciding which scheduling system is best for your business.

Key takeaways:

• Forward scheduling begins production immediately upon receiving the order. Backward scheduling, on the other hand, plans production to meet a desired delivery date.
• Forward scheduling minimizes manufacturing downtime but may result in resource bottlenecks. That is due to a tightly packed schedule.
• Backward scheduling offers greater flexibility in the manufacturing schedule. Yet, it requires precise adherence to project timelines.
• Manufacturers should consider customer expectations and storage capabilities when choosing between these scheduling strategies.

Understanding Backward Scheduling

Backward scheduling is also known as reverse scheduling or just-in-time (JIT) manufacturing. It involves setting a project's final deadline first and then planning backward from that date.

Once you have the project due date (typically set by your customer), you calculate the duration of each project phase, starting from the end date and working backward.

Once you've determined the duration of each phase, you can identify the project start date to ensure it's completed by the due date.

For example, imagine a manufacturing company receiving an order with a delivery deadline of six days. Knowing that delivery will take one day and manufacturing will need three days, you can calculate the start date accordingly.

This indicates that the project's lead time is four days, requiring work to begin on day two and not earlier.

Managing this system involves handling many components. That's why many suggest using software such as material requirements planning (MRP). Or, enterprise resource planning (ERP) for more efficient planning.

This software aids manufacturing companies in effectively planning their projects. The algorithm utilizes factors like required resources and resource availability to schedule projects and ensure they meet critical deadlines seamlessly.

Advantages and disadvantages of backward scheduling

Both benefits and drawbacks exist with backward scheduling.

Let's begin by examining the primary advantages of backward scheduling.

• Reduced costs. With items made to order, there is minimal waste. There's also no need for storage or carrying costs as items ship immediately.
• Enhanced flexibility. This strategy allows for easier adjustments to accommodate high-priority orders or shorter delivery times in manufacturing.
• Decreased risk. Planning materials and resources in advance reduces the risk of encountering shortages.

Now, let's consider the primary disadvantages of this system:

• Limited schedule flexibility. There's minimal room for adjustments if issues occur during any project phase.
• Challenges with unexpected orders. Fulfilling a sudden increase in orders can be challenging with this scheduling method.

Understanding Forward Scheduling

Forward scheduling includes determining the needed time to complete an order starting from its receipt.

In this approach, manufacturing begins immediately upon receiving the order, regardless of the delivery date.

For instance, suppose you receive an order for an item with a ten-day delivery deadline, and it takes five days to produce the item.

In forward scheduling, production starts immediately. It ensures the item is ready five days before the shipping deadline.

It seems ideal, doesn't it?

However, there's more to consider...

This can raise storage issues, including the expenses associated with storing items that are ready too early. These costs, along with the extra workload, can accumulate rapidly. We will delve deeper into this topic later on.

Advantages and disadvantages of forward scheduling

There are advantages and disadvantages to this production process.

First, let's explore the advantages of forward scheduling.

• Optimizing workforce utilization. With forward scheduling, your team immediately works on customer orders upon receipt. That enables efficient workflow organization for higher output and quicker order fulfillment.
• Reducing downtime. By addressing each order promptly, resources can be easily adjusted to meet demand. It minimizes downtime and enhances productivity.
• Early completion. Starting manufacturing promptly upon order receipt increases the likelihood of finishing orders ahead of schedule. That ends up reducing the risk of deadline interference.

Now, let's consider the drawbacks of forward scheduling:

• Extended lead times. Operating at the largest capacity leaves little room to ramp up workflow in response to increased orders. That can result in longer customer wait times.
• Resource depletion. Immediate use of materials upon order receipt can lead to material shortages and production delays.
• Higher risk of bottlenecks. Constant order fulfillment may result in bottlenecks when new orders or last-minute changes need waiting for materials and resources to become available.

With eLogii route optimization software, you can cut delivery scheduling worries.

Our software enables you to plan deliveries in advance, enhancing efficiency in meeting forward-scheduling delivery dates.

Differences Between Backward and Forward Scheduling

Here's a summary of the distinctions between each scheduling approach.

• Methodology. Forward scheduling initiates manufacturing immediately upon receiving the order, while backward scheduling plans from the desired delivery date to minimize idle time.
• Due dates. Backward scheduling is effective for customers needing specific delivery dates, as it counts backward from the due date. Forward scheduling may not always ensure precise delivery timing. eLogii can assist in this area by enabling you to optimize delivery routes and ensure on-time delivery to meet deadlines.
• Inventory costs. Backward scheduling avoids inventory storage costs by shipping products immediately after completion. In contrast, forward scheduling often requires storage until delivery.

Given these differences and other considerations, which scheduling strategy aligns best with your business needs?

Which scheduling approach—backward or forward—is more suitable for your business?

Those seeking this answer often desire a clear-cut response like "One option is vastly superior."

Yet, such a definitive choice isn't workable here. Both scheduling strategies are effective, albeit in distinct ways.

The question isn't about which scheduling approach is universally best, but rather which one is best suited to your specific needs.

Typically, make-to-stock manufacturers use forward scheduling. This enables them to maintain regular stock levels to fulfill customer orders promptly.

Conversely, businesses that follow a make-to-order model often prefer backward scheduling. This is because it enables them to optimize production schedules for maximum efficiency.

However, this isn't a rigid rule.

Depending on your specific business requirements, you may have valid reasons to favor one scheduling method over the other.

Another approach is to combine both methods. That allows you to leverage each scheduling process based on specific needs.

For example, backward planning can be utilized for regular orders to maintain operational efficiency.

During slower periods and considering resource availability, forward scheduling can then be employed to replenish safety stock effectively.

If you have the flexibility to choose between backward or forward scheduling based on your business needs, what factors should you consider when making this decision? Let's explore.

Factors to Consider When Choosing Between Backward or Forward Scheduling

Here are several factors to consider when choosing between these two scheduling methods.

Customer expectations

Conversely, backward scheduling is the preferable choice when dealing with a tight manufacturing schedule and limited resources for storing products.

Your priorities

What is your top priority in manufacturing?

If you prefer fulfilling orders as they arrive and keeping some products in storage for efficient future order fulfillment, forward scheduling could be a suitable approach for you!

Are you inclined towards having a clear view of upcoming tasks in advance? In that case, backward scheduling might align better with your preferences.

Of course, remember that you can always combine these two strategies. It can help create a customized approach that suits your specific business requirements.
