In this week’s lecture we learned about different kinds of changes for a project. They were non-essential design change (NDC), design change number (DCN), and engineering change order (ECO). So my question is, if any of you have experienced firsthand one of these or another kind of design change. I, for the most part, have dealt with “Design Change Number” quite a few things. Usually because of a change to a component in the BoM that I updated or changed based on feedback from the customer or observations when using samples of the part, which as a result caused me to submit a change request to the team. So what about you?
