What is the primary difference between minor and major Engineering Change Proposals (ECPs)?

The primary distinction between minor and major Engineering Change Proposals (ECPs) lies in the level of risk associated with the changes being proposed. Minor ECPs are generally characterized by low-risk modifications that do not significantly impact the overall design or functionality of a project. These changes tend to be straightforward, often involving adjustments that have been thoroughly vetted and are less likely to create unforeseen complications or costs.

In contrast, major ECPs typically entail substantial changes that could significantly alter the project’s scope, design, or functionality, often involving higher risks that necessitate a more rigorous review process. This difference in risk level is crucial for managing the implications of the proposed changes effectively. Understanding this distinction helps ensure that ECPs are categorized appropriately, allowing for the correct processes and reviews to be applied based on the magnitude and potential impact of the changes.

This understanding also highlights why other choices do not align with the core concept of the differences between minor and major ECPs. For example, the idea that minor ECPs could be more expensive or that stakeholder input is not needed for minor changes does not reflect the nature of minor versus major proposals accurately. Additionally, the order of review for major ECPs is not a defined rule, as the review
