I think shortening the time frame will ultimately increase the project risk which is not a good idea. Risk management is an integral part of the medical device product development life cycle. It helps medical device developer ensuring that the product is reliable works as expected and causes no harm to the end users. If the end product that is the medical device is not meeting the expectation of the standards then there no use of decreasing the animal testing it will cause product recall ultimately. The efficiency and the output of the product will not be known. I think adding more time for testing and experiment will achieve the expectation of the product performance. The time should not be too long for the animal testing as it will be waste of the resources.
