Medical device manufacturers make changes to the existing products most of the time but changing in the project will have some effects. The things that should be looked for while evaluating a change request is that is there a change necessary for the overall success of the project. The change required could be small or big if the change is big then it will affect the whole project output. Will the change add or alter the product requirements. Will the change delay the project end date so enacting this change will now make more sense than delaying it will the delay end up costing the project more money in the end. Will the change in the project would produce better device resulting in better performance and end user is satisfied using this device.
