ECO gives the chance for a team to admit a mistake was made or a design can be approved and effectively, document and execute that change. The process is first identifying the mistake or improvement and then documenting it properly on a diagram or official drawing as well as updating a procedure to include the change. Then the change is sent out for review where management and everyone affected can review and give comments. The team then incorporates and discusses the comments and updates the diagram/drawing and procedure. The change is then sent out for signature to all parties involved, denoting they concur with the changes. The changes are then updated officially in the diagram/drawing and procedure. This process ensures that everyone is aware of the changes and finds anymore problems or improvements before the output is officially published.

Any necessary change to the design or documentation must go through COs. The purpose of ECOs and any change orders is to properly document the proposed changes for traceability purposes. These COs are then reviewed and sent to the various departments for approval. These changes may undergo amendments based on the input of other departments if necessary. Additionally, they must include the full scope of other documentation affected, as gingeranderson mentioned. Typically redlined documentation is also attached so changes are transparent and easily visible for approvers and auditors. Appropriate justification is required to put through these changes and verification of full documentation completion is then overseen by the company's documentation services department.

I agree with previous comments about what the overall Engineering Change order is the flow of it and how it is beneficial. Since these comments mostly covered the essentials, I would to alternatively add to the discussion the side effects that engineering change orders may add. The process is crucial they can cause a major delay to the project and very costly. I found this link very useful to the overall understanding and managing process of ECOs.

I definitely agree with the posts above about the whole process of Engineering Change Orders and how beneficial they can be to a specific design of a project. They are used to track any major changes to a design based on efficiently they can improve the design or if it's to simply fix a mistake. Another benefit I would like to add is because of its need to be tracked and documented it also serves as a reminder on what's best for a design in the future or what can or can't work when it comes to a design. It is basically a lesson learned on what makes the design efficient just in case there was to be a similar design for another project later on down the road. A lot of projects I've worked on at my job leverage very similar features when it comes to the design and we've saved a lot of time because of engineering change orders that have been documented in the past

Engineering change order (ECO) is an official change notice that one initiate upon seeing something wrong in the process or if there is a documentation discrepancies in the engineering drawing. After the initiator fills in the necessary action, it then is routed for an approval from the higher management. Basically, the higher management just makes sure that it is okay to perform the specific action. One of the benefits of having ECO is that it alerts the team in the company of an upcoming change in the project. Furthermore, this also ensures that the same mistake doesn’t happen by any other employee. Also, many times it is necessary to review the previous documented ECO to make sure the engineer incorporate the best possible process in manufacturing. All in all, ECO’s are very helpful in determining the accurate and efficient process for a new project.

Mistakes are always tolerable but it should be recovered before the device or product come into real world. I personally feel ECO can alert the team members to be cautious about each and every step ahead. Once there is a change in the project due to some mistakes or lacks then the management seems it to be a serious issue and it will be taken into consideration. This allows the team members to discuss about the project changes and helps in preparation of the further more changes in the validation and verification. I do not have any industrial experience but I have faced changes in the research work, which leads to lot of impact on the entire data analysis. For instance a filter change in the signal processing may cause a major change in the results. So a keen watch of the development and changes in the measure should be seen.

ECOs admit that no design is ever completely perfect, infallible. They are neither a positive or negative event, ECOs are an eventuality. The cause could be: a design error evident only during the testing phases of the product; change in customer needs, market demands, and/or governmental regulations or policies; manufacturer problems such as not enough material and/or material specification changes according to changes in the design. All previous post did a good job of outlining the ECO process as well as the information they contain. Overall, ECOs produce instruction because they identify the change, characterize the change, list those affected by the change, reason the change, and determine when the change should be implemented. Instructions are important because they establish control and direction over any obstacles the team might face during project/product development.

Engineering change orders are a critical aspect of design and process improvements. The description of the ECO has been echoed by many of the previous posts. ECOs are often critical controlled documents that enable changes to designs or processes to be appropriately documented. In my personal experience, ECOs are often initiated as the result of non-conformence events (NCEs) and corrective actions and preventative actions (CAPAs). While not all NCEs and CAPAs require an ECO, many of them do in order to officially document critical changes. Many NCEs often lead to CAPAs, and all CAPA documents in my company usually designate a space for an ECO reference so that continuity can be maintained and documented.

Once the problem is identified by someone and it requires a change.The scope of the issue and its possible impact are estimated before generating an engineering change request (ECR) to examine the feasibility of the change that might include identification of parts, components,resources, estimation of the costs and change in documentation to implement the change.Once an ECR is reviewed by the stakeholders and is modified.An engineering change order (ECO) is generated, listing all the items, documentation, CAD files, standard operating procedures (SOPs) to bring about the change. Once it is accepted by the stakeholders, notification is sent to the team for the change in the process. There are several benefits of implementing ECO process such as consistent identification of the bottlenecks to improve the process, facilitates better collaboration with the stakeholders, improves the supply chain process, supports better communication among the team.

Designing change request is an official change see that one start after observing something incorrectly all the while or if there is a documentation inconsistencies in the building drawing. After the initiator fills in the important activity, it then is steered for an endorsement from the higher administration. Fundamentally, the higher administration just ensures that it is alright to play out the particular activity. One of the advantages of having ECO is that it cautions the group in the organization of an up and coming change in the venture. Besides, this likewise guarantees a similar mix-up doesn't occur by whatever other worker. Likewise, ordinarily it is important to audit the past reported ECO to ensure the designer join the most ideal process in assembling. With everything taken into account, ECO's are exceptionally useful in deciding the exact and productive process for another venture.

An engineering change order (ECO) is a documentation packet that outlines the proposed change, lists the product parts that would be affected. ECOs are used to make modifications to components, assemblies, associated documentation and other types of product information. A good ECO contains the full description, analysis, cost and impact of a change. Having an organized method of handling product changes reduces potential design, manufacturing and inventory errors, minimizes development delays and makes it easy to get input from different departments, key suppliers, and contract manufacturers.
Keeping a record of product changes will also help you debug any problems that occur after your product launches. The task of identifying and fixing the root cause of any problem is easier when you have a complete product change history document.

The stages of the Engineering Change Order are 1) Issue Identification and Scoping, 2) An engineer change request is created, 3) the engineer change request is reviewed, 4) The engineer change order is created and reviewed, 5) the change order circulates to each department, 6)if approved the change is implemented. The benefits of the ECO is that it provides a way to keep product development changes on track as well as keeping it as accurate as possible. If necessary, an engineer can go back and view the change history as well.

An engineering change order is an important part of a project and it begins when someone on the project team identifies an issue or problem that may require a change to be made. After an issue has been identified and before an ECO a document called the engineering change request is completed to initiate the change process by identifying the problem or potential improvement. The ECR is reviewed and modified and if it is approved than an ECO can be created. The ECO is then circulated to all key stakeholders and team members and then a decision is made to make the change. If the ECO is approved than the change is made.

Engineering change orders allow engineers and others to make changes to documents, parts, etc. Typically one or more potential changes are discussed in a meeting or in a brief conversation. Then the person who becomes responsible for making the changes needs to discuss the changes with the applicable departments to speed up the Change Request process. After that, a change notice is created with the applicable documents and approvers attached to the CN. The CN is then routed to the approvers and document services to ensure that all departments agree and that the changes comply. A final review of the changes is done then the change is implemented into the document. Lastly, all those within the scope of the procedure changes are to train to the new changes made.
