Engineering Change Orders (ECO) Basics for SMEs: Process, Best Practices, and Emerging AI Trends
Learn Engineering Change Order basics for SMEs: common challenges, key workflow steps, best practices, and how AI may improve efficiency.
Engineering Change Orders (ECOs) are used to record design changes, evaluate their impact and determine the necessary approvals. For small and medium-sized enterprises (SMEs), properly managing ECOs is crucial, as it helps ensure product updates proceed as planned and avoids costly mistakes. This article introduces the basic concepts of ECOs, common challenges with manual processes, best practices, and briefly explores how future AI tools may improve change management efficiency.
What Is an ECO?
An ECO is a formal record that details the proposed design change, the reason for the change, the affected components and the approvers required. A structured ECO process helps prevent unauthorized modifications, loss of information and schedule delays.
Challenges of Manual Management
Many companies still rely on emails and spreadsheets to control engineering changes. This often leads to:
- Scattered information: Files and comments are stored in different emails or folders, making them hard to track.
- Version confusion: Without consistent version control, the team may use outdated files.
- Inefficient collaboration: Fragmented communication channels slow down approvals and cross-department coordination.
To overcome these problems, SMEs need clearly defined processes and a unified platform.
Key Steps in the ECO Workflow
A complete ECO workflow usually includes the following six stages:
- Submit change request: Team members formally record the proposed change, explaining the reason, affected parts, cost considerations and schedule. This establishes accountability.
- Impact assessment: Relevant teams evaluate how the change will affect other components, manufacturing processes, costs and schedules, and identify potential dependencies.
- Stakeholder collaboration: Representatives from engineering, quality and manufacturing departments jointly review and refine the plan.
- Implementation: Approved changes are executed under strict version control and documentation standards.
- Approval process: Only authorized personnel can approve changes, ensuring appropriate oversight based on the complexity and cost of the change.
- Closure and verification: The team verifies that all changes have been implemented correctly, updates documentation and archives the record.
SMEs should map out current processes, identify bottlenecks and use workflow tools to optimize these stages.
Version Control and Audit Trails
Detailed version control is essential for compliance and accountability. Each change should record the timestamp, implementer and description. Complete audit trails not only meet regulatory requirements but also help solve problems, share knowledge and provide references for future design decisions.

Building an Approval Process
An effective approval process must ensure supervision while avoiding inefficiency. Recommended measures include:
- Clarify roles: Specify who can submit changes, who reviews them and who has final approval authority.
- Set approval levels: Determine approval tiers based on the cost and impact of the change.
- Use digital tools: Electronic signatures and automatic notifications keep the process flowing smoothly.
- Continually optimize: Remove unnecessary steps and periodically review whether the process is still appropriate.
Future Outlook: The Potential of AI in ECO Management
Many companies still depend on traditional methods, but artificial intelligence has the potential to improve ECO management efficiency in the future. Examples include:
- Automatically drafting change descriptions and summaries.
- Analyzing modifications’ impacts on related components, costs and schedules.
- Recommending appropriate approvers based on historical data.
These functions are not yet widespread, but they show the direction of technological development. When planning long-term improvements, businesses can pay attention to the progress of these technologies.
Action Recommendations
- Review existing processes: Use flowcharts or audits to identify current pain points in management.
- Develop unified templates: Ensure information is complete to avoid back-and-forth confirmations.
- Train team members: Ensure everyone understands their responsibilities and workflow steps.
- Focus on automation tools: Gradually introduce workflow management software to improve efficiency.
- Continually improve: Regularly review and optimize processes and keep up with new technology developments.
Frequently Asked Questions (FAQ)
Q: What is an Engineering Change Order (ECO) and why is it important?
A: An ECO is a formal process used to manage and document changes to a product design. It ensures that all stakeholders (engineering, manufacturing, procurement) review and approve the change before it is implemented. Using a formal ECO process prevents costly errors and ensures accurate revision history.
Q: What are the best practices for implementing an ECO process in an SME?
A: Best practices include: defining clear roles for submission, review, and approval; using a centralized system like CAD ROOMS to manage the workflow; ensuring all affected documents are linked; and maintaining a complete audit trail of the entire process. You can learn how to create and manage ECOs in CAD ROOMS.
Q: How does CAD ROOMS manage the ECO workflow?
A: CAD ROOMS provides a built-in, customizable ECO workflow. Engineers submit a change request, which automatically routes to the designated reviewers and approvers. The system tracks the status (Draft, Review, Approved, Rejected) and automatically releases the files to the next stage upon final approval.
Q: What is the difference between an ECO and an ECN (Engineering Change Notice)?
A: An ECN is a notice or document that describes the proposed change. An ECO is the formal process and document that authorizes the change. In CAD ROOMS, the ECO is the central workflow that manages the ECN and all associated files.
Q: How can I ensure all stakeholders review the ECO promptly?
A: CAD ROOMS automatically sends notifications and reminders to reviewers when an ECO is pending their approval. The centralized dashboard shows all open ECOs and their current status, helping to streamline the review process and prevent bottlenecks.
Q: Can I link specific CAD files to an ECO?
A: Yes. Every ECO in CAD ROOMS is directly linked to the affected CAD files and documents. When the ECO is approved, the system automatically creates a new revision of the linked files, ensuring accurate revision history and preventing manufacturing from using outdated designs.
Q: How does the ECO process relate to file release for manufacturing?
A: The final step of an approved ECO is often the formal release of files to manufacturing. CAD ROOMS automates this by creating a controlled, locked revision of the files that is marked as 'Released' and accessible only to the manufacturing team.
Q: What are the common pitfalls of a manual ECO process?
A: Manual ECO processes rely on email, paper forms, and shared drives, leading to: lost documentation, unapproved changes, manufacturing using the wrong revision, and long approval cycles. CAD ROOMS digitizes and automates the process, eliminating these risks.
Q: Can I customize the ECO workflow in CAD ROOMS?
A: Yes. CAD ROOMS allows administrators to customize the ECO workflow to match your company's specific approval structure (e.g., requiring sign-off from Engineering Manager, Quality Assurance, and Procurement).
Q: How does the ECO process help with compliance and quality control?
A: The ECO process provides a complete, traceable record of every design change, which is essential for ISO 9001 compliance and quality control. The audit trail ensures that every decision is documented and approved.
