  • Dealing with unexpected changes in production planning

The production planner is responsible for creating a streamlined and efficient production schedule. One of the biggest challenges he faces daily are unexpected changes that can turn the entire schedule upside down. This article discusses the many types of changes that can occur and explains why it is so difficult to deal with them.

Last-minute changes

These are unexpected changes that occur last minute, often just before production is actually due. These last-minute changes can have a significant impact on planned production activities and are often a major source of stress and complexity for a planner. This could include a customer placing a rush order, a change in product specifications, or even a complete cancellation of an order. These changes can result in disruption to existing production schedules, and it requires quick action and flexibility to deal with them.

The biggest problem with last-minute changes is that they often lead to a race against the clock. The planner must immediately analyze the impact of the change and assess how it will affect the ongoing production schedule. Dealing with last-minute changes requires a degree of flexibility and the ability to prioritize. Sometimes other orders must be rescheduled or resources reallocated to meet the new requirements. This could result in a delay for other customers.

Despite the challenges posed by last-minute changes, it is important to remember that they are an unavoidable part of the production process. A planner must remain flexible, able to move quickly and come up with creative solutions to manage these changes effectively.

Supply chain changes

Another challenge is dealing with changes in the supply chain. These could be delays in the delivery of raw materials or materials, changes in suppliers or quality control problems. These changes can disrupt planned production and lead to workflow interruptions. A production planner must then find alternative sources, adjust the schedule and ensure that there are minimal disruptions to production operations.

Production constraints and technical problems

The occurrence of production constraints and technical problems is another source of challenges for a planner. These could be machine failures, maintenance work, quality problems or personnel shortages. Such changes can reduce planned production capacity and increase lead times. It is the production planner’s job to react quickly, find alternative solutions and adjust the schedule to minimize the impact on production.

New product introductions or changes in product design

Introducing new products or changes in product design often presents challenges for production planning. This may require new machinery or tools, additional training for staff or revising existing processes. Planning and integrating these changes into production operations requires accuracy and careful coordination to ensure that everything runs smoothly and quality is maintained.

Why it is so difficult

Dealing with these changes and adjusting production schedules is a complex and challenging task. It requires a combination of analytical skills, experience, communication and the ability to make quick decisions. Some of the reasons why this is so difficult are:

Time Sensitivity: Changes can occur at any time and require quick reaction times. Planning alternatives, reallocating resources and reconfiguring the flow of production often must be done within a very short time.

Impact on efficiency and costs: Changes may affect production efficiency and incur additional costs. A planner must make sure to strike the optimal balance between meeting the changes and minimizing the impact on cost and efficiency.

Coordination with stakeholders: Dealing with changes requires close cooperation and communication with various stakeholders, such as suppliers, production staff, management and customers. Aligning expectations and coordinating actions is critical to effectively managing change.

Risk management: Dealing with changes involves inherent risks. Identifying potential risks and taking measures to mitigate them is essential to protect production from unwanted disruptions.


A production planner is confronted daily with various types of changes that can disrupt the planned production schedule. Juggling these changes is challenging because of the complexity, time sensitivity and impact on efficiency and cost. It requires a combination of skills, experience and collaboration with stakeholders to effectively manage these changes and maintain a streamlined production schedule.
