What is a Manufacturing Change Process?

Manufacturing Change Process Definition

Manufacturing change process is a subset of engineering change management. Engineering change management involves creating, reviewing, and gaining formal approval for engineering change requests (ECRs), engineering change orders (ECOs), and engineering change notifications (ECNs). It also encompasses the process to identify, review, and approve a manufacturer’s parts.

A manufacturing change order (MCO) is used to make a manufacturing change to a part or product. This typically does not involve a design change to a part or product. An example is a change to the approved manufacturer list (AML) or a change in the manufacturing processes used to produce a part. If a MCO does require a design change it is often accompanied by an ECO.

A manufacturing change request (MCR) is used to propose a manufacturing change that does not require a design change to an item or to product design.

How do you implement change in manufacturing?

A manufacturing change often begins when a shop floor worker, supervisor, or member of the engineering team notices a problem on the manufacturing line such as glue failure or a line backup and ends when key stakeholders agree on a solution. A good manufacturing change process feeds data back into the design process, allowing engineers to be informed about manufacturing line issues and apply that knowledge to current and future design iterations. Changes in manufacturing should be documented so that issues may be handled quickly. A manufacturing change request (MCR) or manufacturing change order (MCO) is typically used to document the change process.

What is the difference between ECR and ECO?

An engineering change request (ECR) can be created by anyone involved in product development or manufacturing process. ECRs provide a general description of issues to be addressed and require engineering management approval before a more detailed engineering change order (ECO) is created and then routed to all stakeholders beyond engineering team for approval. The stakeholders that review ECOs are generally referred to as change control boards (CCBs). Once all members of the CCB approves the ECO, it can be implemented and acted upon by purchasing and manufacturing teams.

What are the steps in manufacturing process?

The steps in the manufacturing process are

  1. Product concept
  2. Research
  3. Design
  4. Create the final design
  5. Testing
  6. Manufacturing and assembly
  7. Feedback and testing
  8. Official release
