I sort of had a similar experience in Capstone as my group had to keep a detailed log of everything that was working out for us and more important what was not working. Our advisor let us find out for ourselves instead of telling us when she knew something would fail and so we went through many design changes throughout the project. In the end we needed to prepare Work Instructions which would closely detail every step of our manufacturing process of our product. This procedure needed to include define temperature and time ranges for certain processes and also materials to be used for different components. Since we would cease working on the project at the end of the semester our advisor wanted this procedure so that she could continue working on the project and incorporate it into her research. She could use it as a guide of what not to do when recreating our product at a different scale. If we did not keep a detailed record of our failed attempts then she could end up wasting even more time and money on designs that would inevitably fail.
