ECOs are used to make modifications to components, assemblies, associated documentation and other types of product information.The main reason for ECO (for example) ,product improvements, or companies might want to research other methods better suited to their own operations. For example, if the product or process changes can impact many areas within your company, including:Customer service, tooling, standards, suppliers, Master production schedule,device problems, or product cost.
I don’t have experience with completing any ECO, but I think we should avoid unnecessary changes for the product to save time and money. However, if a change in a product pays back in a year, for sure I go for it!.It’s all about quality and profit.
