Whether driven by customer feedback, quality concerns, regulatory updates, or opportunities for optimization, ECRs enable organizations to respond proactively to emerging challenges and market trends.

By initiating an Engineering change request (ECR), companies can ensure that proposed changes are thoroughly vetted, their impact is assessed, and all necessary stakeholders are involved in the decision-making process.

Furthermore, ECRs promote collaboration and communication among cross-functional teams, fostering a culture of innovation and problem-solving within the organization.

They help break down silos and encourage a holistic approach to product development and manufacturing, ultimately leading to better quality, increased efficiency, and enhanced customer satisfaction.

Types of Engineering Change Request

While the engineering change request (ECR) is the most common type of change request, several other variants address specific needs within the product development and manufacturing lifecycle.

Engineering Change Request (ECR) – Definition and examples

As previously discussed, an ECR is a formal proposal for modifying or enhancing an existing product design, component, or assembly.

Examples of situations that may trigger an Engineering change request (ECR) include:

• Addressing customer complaints or field failures
• Incorporating improvements based on user feedback
• Resolving non-conformities or quality issues
• Updating components to leverage new technologies or materials

Manufacturing Change Request (MCR) – Definition and use cases

A manufacturing change request (MCR) is focused on proposing changes to the manufacturing process or equipment used in production.

MCRs may be initiated to improve efficiency, reduce waste, enhance safety, or address production-related issues. Common use cases for MCRs include:

• Modifying assembly procedures or workstation layouts
• Introducing new production equipment or tooling
• Optimizing process parameters or quality control measures

Document Change Request (DCR) – When to use a DCR

A document change request (DCR) proposes revisions or updates to product documentation, specifications, or standard operating procedures (SOPs).

DCRs are typically initiated when errors, inconsistencies, or opportunities for clarification are identified in existing documentation.

They ensure that all relevant documentation remains accurate and up-to-date throughout the product lifecycle.

Corrective Action Request (CAR) – Addressing critical product issues

A corrective action request (CAR) is a specific type of change request that addresses critical product issues or non-conformities that require immediate attention.

CARs are typically raised in response to significant quality concerns, safety hazards, or regulatory violations.

They trigger a thorough investigation and implement corrective and preventive actions to resolve the issue and prevent its recurrence.

Key Components of an Engineering Change Request (ECR) Form

Regardless of the type of change request, a well-structured Engineering change request (ECR) form is essential for capturing all the necessary information and facilitating a smooth evaluation and implementation process.

An effective ECR form should include the following key components:

Problem description and reason for change

This section should provide a detailed description of the issue or opportunity that necessitates the change request.

It should clearly articulate the problem being addressed, the impact it has on the product or process, and the rationale for pursuing the proposed change.

Affected part numbers and descriptions

The ECR form should identify all the specific part numbers, components, or assemblies that will be impacted by the proposed change.

Accurate part descriptions and revision levels should be included to ensure that the correct items are targeted for modification.

Originator details and submission date

The name, department, and contact information of the individual or team initiating the Engineering change request (ECR) should be clearly stated, along with the date of submission. This information is critical for tracking the request’s origin and facilitating communication throughout the evaluation process.

Stakeholder information and feedback

The ECR form should include a section for capturing the names, roles, and feedback of all relevant stakeholders involved in the review and approval process.

This ensures that all affected parties have an opportunity to provide input and that their concerns or recommendations are documented.

Proposed solution and next steps

While not always required, it can be beneficial to include a proposed solution or course of action in the ECR form.

This section should also outline the next steps in the evaluation and implementation process, such as conducting feasibility studies, risk assessments, or obtaining necessary approvals.

Engineering Change Request (ECR) Process Flow

The ECR process flow outlines the sequential steps involved in initiating, evaluating, and implementing a change request.

While the specific details may vary across organizations, the general process typically follows this structure:

Initiating an Engineering Change Request (ECR)

The ECR process begins when an individual or team identifies a need for change and submits a formal Engineering Change Request (ECR) form.

This form should be completed with all the necessary information, including a detailed problem description, affected parts, and any proposed solutions or recommendations.

Review and evaluation by stakeholders

Once an ECR has been initiated, it is circulated among relevant stakeholders for review and evaluation.

This stage involves cross-functional collaboration, where subject matter experts from various departments (engineering, manufacturing, quality, procurement, etc.) assess the impact of the proposed change and provide their feedback or recommendations.

Engineering Change Order (ECO) creation

If the Engineering change request (ECR) is approved after the initial review and evaluation phase, an Engineering Change Order (ECO) is created.

The ECO is a formal document that outlines the specific details of the approved change, including the implementation plan, responsible parties, timelines, and any necessary supporting documentation or drawings.

Implementation of approved changes

With the ECO in place, the approved changes can be implemented according to the defined plan.

This may involve modifying product designs, updating manufacturing processes, procuring new materials or components, and conducting necessary testing and validation activities.

Documentation and communication

The final step in the ECR process is to thoroughly document the implemented changes and communicate them to all relevant parties.

This includes updating engineering drawings, bills of materials, work instructions, and any other affected documentation.

Effective communication ensures that all stakeholders are aware of the changes and can adjust their processes accordingly.
