You make a good point tn58. This will certainly affect the overall project and may require reallocation of time in the preliminary steps of the project schedule. Not only R&D, but other phases such as testing and verification will need to be altered. This could create a significant delay, but the reconsideration of what criteria the device has to meet may end up salvaging the situation without starting from scratch. This was the case with our first simulation, in which the verification testing was using an unnecessarily high temperature. And instead of getting new adhesive, labels etc. The tests were modified and allowed for the appropriate verification of the project.
