At one point or another, manufacturers will encounter bottlenecks within their production. When your production levels are consistently lower than what you have predicted, or you are unable to meet your shipment dates, you are most likely dealing with a bottleneck.
Bottlenecks are operations that are constraining the entire production system. They are often caused by the inefficient use of available resources, poor coordination, or misallocation of human resources.

It is possible to have multiple bottlenecks within an operation that are reducing the production output and enabling shipment delays. This is problematic for manufacturers as customer satisfaction is a high determinant of whether they will choose your company over another. When you cannot meet a promised shipment date, customer satisfaction decreases and could jeopardize your business’ reputation in the market.
These bottlenecks could also be affecting anything from throughput, wait time, waste reduction, or even the lack of proper raw materials needed at a particular point in time. Issues arising in any of these factors can lead to a decrease in production efficiency. This is why it is important to locate and attempt to eliminate potential bottlenecks within your operation.
In this blog, we will discuss the three steps that pertain to eliminate bottlenecks to allow your production facility to increase its productivity and meet its shipment dates.
3 Steps to Eliminate Bottlenecks Causing Production and Shipment Delays
The three steps in combating bottlenecks within production include the following:
1. Locating Bottlenecks
Almost every process has a bottleneck, no matter how small it may be. If your schedule is indicating a delayed planned end but your machine runtimes should allow you to deliver on time, you are likely dealing with one or multiple bottleneck operations.
Bottlenecks can usually be identified by operations that have the most accumulation of work in front of it. Downstream processes must then wait for resources coming from this bottlenecked operation even though they would be able to start it immediately.
A visual scheduling system is helpful for identifying bottlenecks as they can highlight or emphasize areas that have a lot of wait time.
Resource performance can also be analyzed to see whether your resource capacities are being used to their full potential.
2. Increase Capacity Efficiency
In the theory of constraints, the key to optimizing your production is to focus on eliminating bottlenecks. Once a bottleneck is identified, you should focus on increasing capacity at this step to increase the capacity of the entire process.
There are many ways in which capacity can be increased, and visual planning and scheduling software that have “what-if” scenario analysis capabilities can help identify which methods should be used.
To increase capacity, it is recommended to optimize the resources you already possess. This means utilizing scheduling rules to minimize the changeover and setup time as well as increasing the number of operators to the bottlenecked operations.
If this is still not enough to sufficiently increase the capacity of the operation, you may need to consider investing in another machine or in additional operators to meet your production quota.
3. Executing New Schedules
Once the bottleneck is corrected through the production planning scheduling software, you can then execute the new schedule and increase efficiency through consumer order fulfillment, increased delivery time, and most importantly, reduced wait times within the overall production process.
It is possible that your production process has more than one bottleneck. In that case, the additional bottleneck operations should be identified and capacity should be increased at those steps.
Eliminate Bottlenecks with Advanced Planning and Scheduling (APS) Software
While it can be challenging to identify bottlenecks within your production facility and optimize your production schedule, advanced planning and scheduling (APS) systems such as PlanetTogether APS can easily enable manufacturing facilities to do so. This software has a multitude of features that will help your company deal with its bottlenecks and ultimately meet its production goals.
Analysis features allow you to look at the production performance of all of your resources to identify any machines or workers that are performing under their expected target. What-if scenario analysis also lets you visually observe how changes to the production schedule will impact your predicted finish dates to see if you can fulfill all of your orders on time.
With PlanetTogether, the accuracy of our shipment dates improved by 8% and our production output levels increased by 16%.

In addition, Capacity Planning features will ensure that you know in advance what you are able to produce so that you don’t create an unrealistic production schedule. This will allow you to always meet your shipment dates and satisfy your customers.
Advanced Planning and Scheduling systems will allow manufacturers to increase their overall production levels, meet their deadlines, fulfill delivery and shipment times, and take their operation to the next level in terms of operational efficiency. These systems have become a must for manufacturers looking to eliminate their production bottlenecks and meet their shipment dates.
PlanetTogether's Advanced Planning and Scheduling Software
Advanced Planning and Scheduling software has become a must for modern-day manufacturing operations as customer demand for increased product assortment, fast delivery, and downward cost pressures become prevalent. These systems help planners save time while providing greater agility in updating ever-changing priorities, production schedules, and inventory plans. APS Systems can be quickly integrated with an ERP/MRP software to fill the gaps where these systems lack planning and scheduling flexibility, accuracy, and efficiency.
With PlanetTogether APS you can:
Using What-If Scenarios to Break Production Bottlenecks
See how manufacturing teams use what-if scheduling scenarios to eliminate production bottlenecks and improve on-time delivery. This video walks through how Advanced Planning and Scheduling (APS) software lets planners compare multiple production schedules, test capacity changes, adjust priorities, and immediately see the impact on shipment dates. Learn how scenario planning helps manufacturers increase throughput, reduce wait time at bottleneck resources, and create realistic, data-driven production plans that the shop floor can execute.
Break Your Bottlenecks Before They Break Your Promises
In this article, you’ve seen how bottlenecks quietly limit throughput, create queues of work-in-process, and lead to missed shipment dates—and how Advanced Planning and Scheduling (APS) with what-if scenarios can help you find and fix them.
Our eBook, “Producing for Profit,” shows what that looks like inside a real manufacturing business. You’ll follow a growing manufacturer that’s struggling with late orders, rising overtime, and constant firefighting around bottleneck resources—until they implement a connected planning and scheduling system that aligns capacity, inventory, and customer demand.
In this story-driven guide, you’ll see how they:
- Identify true bottlenecks that are capping throughput
- Use what-if scheduling scenarios to test capacity changes before spending on new equipment
- Improve on-time delivery while reducing expediting and last-minute overtime
- Turn ERP data into realistic, optimized production schedules planners can actually trust
If you’re serious about eliminating bottlenecks and protecting your promised shipment dates, this is the next step.
