How Operational Entropy is Undermining Any Airline (and How to Fix It)

The Consequences of Operational Entropy in Airlines and How to Fly Towards Excellence

Why do once-efficient operations start slipping into inefficiency? Why does a well-oiled airline suddenly struggle with delays, rising costs, and operational bottlenecks?

Ever wondered why things seem to get messier as time goes on? It’s not just your living room after a few days of intense productivity—it’s a universal truth! This is entropy in action, the tendency of systems to move from order to disorder over time. In the world of aviation, this concept is just as real.

At The Lean Airline, we know that understanding and managing operational entropy is the key to achieving Operational Excellence. Imagine an airline operating at its peak, with smooth operations, on-time flights, and satisfied customers. Now, picture that same airline, over time, facing inefficiencies, rising costs, and frustrated employees. What happened?

In this post, we’ll explore how entropy affects business and operational performance, why it’s critical to address it, and how methodologies like Lean, Kaizen, and Six Sigma can help transform chaos into opportunity. Let’s go!

What is Operational Entropy?

The term "entropy" comes from thermodynamics, where it refers to the degree of disorder or randomness in a system. In simple terms, entropy is the tendency for everything to move from order to disorder over time. This principle can be applied not only in physical systems but also in business and operational environments.

For example, think of an aircraft cabin at the beginning of a flight. Everything is neatly arranged—passengers are seated, their seat belts are fastened, carry-on baggage is properly stowed, and the galley is stocked with food and beverages. This is a state of low entropy. As the flight progresses, however, the cabin tends to get messier. Passengers may leave wrappers on their tray tables, and food packaging or litter may be scattered around. The tidy environment now reflects a higher level of entropy. Restoring the cabin to its original state after the flight requires external effort—such as the work done by ground handling staff to clean and organize the cabin before the next flight.

This example of an aircraft cabin illustrates how entropy works in real-life scenarios. Over time, systems and processes naturally move towards disorder unless external energy or effort is applied to maintain or restore order.

Business Entropy and Its Impact

As companies grow and evolve, their structures, processes, and strategies may misalign with their value propositions. Just like the cabin, business systems can accumulate waste, inefficiencies, and disorder that drive high levels of entropy.

If an organization does not take active steps to manage and reduce this disorder, it can lead to significant negative consequences. These might include:

  • Increased costs: Resource waste, longer lead times, increased labor requirements, and unnecessary inventories can all result from high business entropy.

  • Decreased customer satisfaction: Delays, errors, and inconsistent delivery of products or services undermine the customer experience.

  • Reduced employee morale: Employees struggle to accomplish tasks efficiently in a disordered environment, which leads to frustration and disengagement.

  • Missed opportunities for improvement: High entropy can make it difficult for an organization to recognize and act on opportunities for cost savings or process optimization.

  • Poor decision-making: When the system is chaotic, it’s harder to make informed and timely decisions that drive the business forward.

These factors contribute to a downward spiral of inefficiency and poor performance, and in extreme cases, they can lead to the failure of the business.

From Chaos to Operational Excellence

The natural tendency of any organization is to experience entropy over time. To counter this, businesses must apply energy—just as ground handling staff apply energy to clean the aircraft cabin. This effort, when applied correctly, is what we refer to as Operational Excellence.

Operational Excellence involves designing and maintaining workflows that are not only efficient but also adaptable to both internal and external changes. It requires a culture of continuous learning and improvement, where employees at all levels are encouraged to identify and solve problems. This approach empowers employees to actively contribute to innovations that improve processes and outcomes.

However, when entropy levels are high, it becomes difficult for employees to exert additional effort to restore order. At this point, the organization needs an external force to evaluate the system objectively, identify the causes of disorder, and help implement solutions.

Overcoming High Operational Entropy

High levels of operational entropy can significantly impede progress. However, by adopting proven methodologies and strategies, organizations can overcome the disorder. Some of the most effective methodologies include:

  • Lean: Focuses on eliminating waste and improving process efficiency.

  • Kaizen: A philosophy of continuous improvement that encourages small, incremental changes.

  • Six Sigma: A data-driven approach that aims to eliminate defects and variations in processes.

  • Agile (including Scrum and Kanban): A flexible and iterative approach to project management and process improvement.

  • Theory of Constraints (TOC): Focuses on identifying and addressing the limiting factors in a system to improve overall performance.

While they share some tools and practices, others are unique to each methodology and/or tailored to their specific objectives. When choosing an approach, organizations should assess their individual circumstances, goals, and existing culture. It is often beneficial to take a tailored approach, selecting elements from different methodologies to create a customized framework that best suits the needs.

Conclusion: The Path to Sustainable Success

Operational Excellence is not a one-time achievement but a continuous journey. By understanding the principles of entropy and actively working to reduce disorder, organizations can unlock significant improvements in performance (safety, financial, and more), customer satisfaction, and employee engagement.
