Engineering change management refers to the change in the functionality of a product by means of careful request, evaluation, implementation and control when production of the product has already started. Depending on the product and the items the changes can be either total or partial. For instance there might be a change only in component, assembly or material.
Changes form part of most products nowadays especially the ones that consist of rapidly evolving technologies. They represent both an engine of innovation, opportunities of benefits, but can also generate cost and delays.
Usually the engineering change management process is made up of 6 processes.
Engineering change request
A formal request which is known as an engineering change request is made and will help define clearly the changes that are needed.
Alternative solutions to the requested change
Alternatives to the ECM are evaluated and the best one is normally taken.
Risk evaluation of the alternatives
Alternatives are normally evaluated in terms of risk and other benefits and also impact on the other departments.
Solution approval
Once a solution seems favorable it needs to be approved by the appropriate managerial department,
Implementation stage
Once approval has been granted the change request becomes a change order and needs to be propagated across the whole organization. Either the changes are done straight away or in some cases the change is made over small phases.
The review stage
The change process is carefully reviewed to ensure that everything went out as planned and that proper documentation is made.
These are the steps that made up a generic engineering change management process but this can vary depending on the type and size of the organization.
