Change Management
Engineering Change Management in PLM
Control product changes from initial request through review, approval, implementation and release. Nora IPLM connects change requests, affected items, BOMs, documents, workflows, approvals and implementation tasks so engineering teams can evaluate impact and maintain full traceability across the product lifecycle.
What Is Engineering Change Management in PLM?
Engineering change management is the controlled process of evaluating, approving, implementing and tracking changes to products, parts, BOMs, documents, requirements and related lifecycle information.
In a PLM environment, every change can remain connected to the product data it affects. This allows teams to understand what is changing, why the change is needed, who approved it, which records are affected and whether implementation is complete before release.
Common Product Change Types
Why Engineering Change Management Matters
Product changes rarely affect only one record. A seemingly small design update can influence BOMs, documents, configurations, manufacturing instructions, project work and downstream teams.
A controlled engineering change process helps teams assess these relationships before implementation and ensures that approved updates move through a consistent, traceable path.
How Engineering Change Management Works
Identify the Change
Capture the reason for the change, supporting information and the product data involved.
Assess Impact
Review affected parts, BOMs, documents, requirements, configurations, baselines and downstream processes.
Define Ownership
Assign reviewers, approvers and implementation responsibilities.
Review and Approve
Route the change through the required technical and business approval workflow.
Plan Implementation
Define tasks, dependencies and the product information that must be updated.
Execute the Change
Update affected product records and complete assigned implementation tasks.
Verify Completion
Confirm that the approved change was implemented correctly across affected data.
Release and Preserve History
Move the updated product information forward while retaining the full decision and change history.
Connected Change Control
Manage engineering changes without losing lifecycle context.
Coordinate reviews, approvals, affected items, and product updates from one controlled PLM workspace.
Streamline Product Change Management Across the Entire Lifecycle
Connect change requests, affected items, approvals, and downstream updates so teams can move faster with fewer handoff gaps.

Engineering Change Request vs Engineering Change Order
Engineering Change Request
- Purpose
- Propose and evaluate a change
- Focus
- Need, feasibility and impact
- Typical Activities
- Problem definition, impact review, recommendation
- Outcome
- Approve, reject or revise the proposal
Engineering Change Order
- Purpose
- Authorize and implement an approved change
- Focus
- Execution, ownership and completion
- Typical Activities
- Tasks, approvals, product updates, verification
- Outcome
- Implement and close the approved change
The exact use of ECRs and ECOs varies by organization, but separating evaluation from execution can help teams create a clearer, more controlled engineering change process.
Common Engineering Change Management Use Cases
Design Changes
Control updates to drawings, CAD data, specifications and product designs.
BOM Changes
Manage part substitutions, additions, removals and quantity changes while preserving product structure history.
Quality-Driven Changes
Turn quality issues, failures or corrective actions into controlled engineering updates.
Supplier or Component Changes
Assess and implement product updates caused by supplier, material or component changes.
Cost Reduction Changes
Evaluate value-engineering changes while understanding technical and downstream impact.
Manufacturing Changes
Coordinate approved engineering updates with production-ready structures and manufacturing information.
Configuration Changes
Control updates that affect product variants, options or configuration rules.
Compliance or Requirement Changes
Trace regulatory or requirement updates to the product information that must change.
Change Impact Analysis Before Approval
A strong engineering change process should evaluate impact before a change moves downstream. Reviewers need visibility into the product records, dependencies and lifecycle processes that may be affected.
This helps teams make approval decisions using product context rather than reviewing the change request in isolation.
Example: Managing a Component Change from Request to Release
A supplier discontinues a component used in an active product. Engineering creates a change request and links it to the affected item and BOM. The team reviews alternative components, checks the related documents and configurations, and evaluates downstream manufacturing impact.
After the replacement is approved, an engineering change order is created. Tasks are assigned to update the BOM, drawings and related product records. Once implementation is verified, the updated product information is released and the complete change history remains traceable.
Product Control
How Engineering Change Management Improves Product Control
Controlled change management protects product integrity while helping teams move approved updates through the lifecycle efficiently. By keeping impact, ownership, approvals and implementation connected, teams can reduce rework and make change decisions with greater confidence.
Reduce change-related risk
Review affected product information before approved changes move downstream.
Keep teams aligned
Keep engineering and manufacturing teams aligned around controlled updates.
Maintain lifecycle control
Maintain approvals, change traceability and a complete history of product decisions.
Accelerate implementation and release
Move approved changes through repeatable workflows with clearer ownership.
Full Visibility
End-to-End Change Tracking for Full Visibility
Track each change request from identification through review, approval, implementation, and release. Teams can see what changed, why it changed, who approved it, and which product data was affected.
Task Ownership
Individual & Group Task Assignments
Assign change tasks to specific users or functional groups so every review, approval, and implementation step has clear ownership and accountability.

Frequently Asked Questions About Engineering Change Management
Engineering change management is the controlled process of evaluating, approving, implementing and tracking product changes across items, BOMs, documents, requirements and other lifecycle information.
An ECR is generally used to propose and evaluate a change, while an ECO is used to authorize and control implementation after the change is approved.
PLM keeps the change connected to the product data it affects, allowing teams to review impact, approvals, implementation and history in one lifecycle context.
Change impact analysis identifies the parts, BOMs, documents, requirements, configurations, baselines and downstream processes that may be affected by a proposed change.
Yes. Change records can be linked directly to affected items and BOM structures so teams can understand where the change applies and what must be updated.
Approval workflows route changes to the correct reviewers and decision-makers, record sign-offs and prevent uncontrolled implementation.
Baselines provide a reference state that teams can compare against later product states to understand what changed and assess impact.
Yes. Change implementation work can be assigned to responsible users or functional groups so ownership and completion remain visible.
It preserves the reason for the change, affected product data, review decisions, approvals, implementation work and final release history in one connected record.
Engineering, quality, manufacturing, product, operations and PLM teams benefit because product changes remain controlled and connected to the lifecycle information they affect.
