  1. Engineering Change Request (ECR)
  2. Engineering Change Order (ECO)
  3. Engineering Change Notice (ECN)
  4. Manufacturing Change Order (MCO)
  5. Stop Order (SO)

What are the basic steps of change management?

Change management involves the following steps:

  1. Identify the process/product design element that needs to be changed
  2. Initiate an engineering change request (ECR) that outlines the reasons, impact, and details for proposed change.
  3. Approve the proposed change with key engineering stakeholders.
  4. Initiate an engineering change order (ECO) and get approval from all product team stakeholders.
  5. Implement changes during the manufacturing process or beyond (field service, if necessary).
