Manufacturing Change Order (MCO)

A Manufacturing Change Order (MCO) is a change order used to make a manufacturing change to a product. An MCO is not generally used to implement a design change to the product. Manufacturing change orders do not require a design change and are often accompanied by an ECO (Engineering Change Order).

A Manufacturing Change Order (MCO), similar to an engineering change order (ECO), is a crucial document in the field of engineering change management and product development, particularly in the context of manufacturing processes and product design. An MCO, like the ECO process, serves as the formalized process for initiating, evaluating, and implementing changes to a product's design, manufacturing process, or related documentation. This systematic approach ensures that modifications and revisions to products and processes are carried out efficiently, with consideration for the impact on stakeholders and the product lifecycle.

The MCO approval process begins with an Engineering Change Request (ECR) or Engineering Change Notice (ECN), initiated by stakeholders such as the engineering team, procurement, or quality control. This request outlines the proposed change to a new product or existing product, providing a detailed description of the change, its rationale, and the type of change it represents (e.g., design changes, revisions, or product changes).

Like the engineering change order process, the MCO workflow involves these key steps:

  1. Proposal: The proposed change is documented, detailing the scope, feasibility, and potential impact on existing products, the manufacturing process, and the supply chain.
  2. Review and Approval: The change request undergoes a rigorous review by a Change Control Board (CCB) or a designated team of stakeholders. This review ensures that the change aligns with regulatory requirements, quality standards, and the overall product development goals. Once approved, the change moves forward.
  3. Documentation: All relevant documentation, including the Bill of Materials (BOM), routing, and any other affected documents, are updated to reflect the approved changes. This step ensures traceability and compliance with quality control measures.
  4. Implementation: The approved changes are then implemented in the manufacturing process. This may involve updating operating procedures, procurement processes, or production processes. Automation can play a role in streamlining these changes and reducing bottlenecks.
  5. Quality Control: Rigorous quality control measures are put in place to verify that the implemented changes meet the desired objectives and do not introduce unintended consequences.
  6. Real-Time Monitoring: Many organizations use real-time tracking and monitoring systems to ensure that the changes are executed correctly and to identify and address any issues promptly.
  7. Feasibility and Regulatory Considerations: Especially in industries like medical devices, where regulatory compliance is critical, the feasibility of proposed changes and their impact on regulatory requirements are carefully assessed.
  8. Product Lifecycle Management (PLM): PLM tools and software may be used to manage and track changes throughout the product's lifecycle, providing visibility and traceability.

MCOs can encompass a wide range of changes, from minor revisions to substantial redesigns. The goal is to ensure that changes are made systematically, with minimal disruption to the production process, and that they enhance the product's quality, performance, or cost-effectiveness.

By utilizing MCOs and the associated change management process, organizations can effectively manage product changes and improvements while minimizing risks and maintaining the integrity of their manufacturing processes. This formalized approach not only enhances the quality of products but also ensures compliance with regulatory requirements, traceability of changes, and stakeholder satisfaction. It plays a pivotal role in maintaining the agility and competitiveness of businesses in the dynamic landscape of product development and manufacturing.
