Global Aerospace Engineering & Design

Manufacturing has a number of variables and moving parts. That requires a certain amount of agility for businesses, and the ability to turn on a dime to adapt components and processes. Whether you are preserving market share, addressing pain points in your supply chain, or otherwise trying to maintain a competitive edge, small changes can make an outsized difference. That’s why Precision Mold and Machining Services has developed a robust set of processes to handle engineering change orders (ECOs).



What is an Engineering Change Order?

Simply put, engineering change orders are a means of addressing changes to manufactured products and processes. It spells out the changes to the product, and the steps needed to affect that change.

When You May Require an Engineering Change Order

What are the circumstances that might require an ECO?

  • Supply chain issues, such as the closing of a supplier, or a shortage of a particular material or component
  • Cost constraints brought on by market forces, tariffs, and other considerations
  • A change in manufacturing processes
  • A desire for higher part tolerances
  • Design changes driven by market demand, regulatory shifts, or shifting use cases

Our ECO Process

ECOs pose challenges for engineering and manufacturing alike. Our experience has taught us that, as in so many other areas of our business, attention to detail makes all the difference. To that end, our processes are tailored to keeping a customer’s experience streamlined and free of confusion.

We begin by having a full understanding of your project from the outset. This allows us to spot potential choke points and make suggestions to address them. We also keep lines of communication open among stakeholders — engineering, manufacturing, and anyone else who needs to be involved — to prevent unnecessary friction. And we keep cycle times short to minimize downtime and maintain a steady flow of product. In practice:

  • Identify the issue, its impact, and potential solutions
  • Create an engineering change request that outlines the affected components, the proposed change, and downstream considerations like costs and documentation changes
  • Submit the change request for review by key stakeholders
  • Upon approval, convert the request to a working ECO
  • Implement the changes in question
