ABSTRACT The world of manufacturing is dependent on and affected by engineering change so greatly that we must not only ensure its issuing but also be able to ensure the implementation. Any failure or discrepancy of the Engineering Change will be duplicated in manufacturing, and cost will be multiplied in business. In this essay, we will talk about how to control the engineering change implementation. To express how to ensure the implementation is correct and on time, we will talk about current ECN process. We will discuss the demands from engineering and manufacturing for implementation, and show...
and processes, human operations should also be under control, so in cooperation, different responsibilities are assigned according to the departments of these people. To prevent any errors of assignment to impact the engineering change, other roles are appointed to see to them.

"ECN's are issued, but not knowing the result in production." "ECO's are executed, but our concerns are not reflected." The gap between manufacturing and engineering is either a system issue or a process issue. But communication always counts. At least we can say the reengineering of system and process is to achieve a better communication.
