In my senior design for my undergrad, I found it very useful to log every single detail in my work. This includes writing tasks to be done, what was done, when and how. I was recording all meetings, and taking different videos of the main parts of the experiment. Since I was the group leader, I had to report all the work done to our advisor. It saved me a lot of time at the end of each semester and made it easier for me to write the final report with all the useful details as was keeping track of all work done throughout the semester. This was not only beneficial for us a group, also for the professor, because at the end, he asked me to create a video that summarizes all the work done so far, so that he can show it to the following group and they will understand the goals done and the overall concept of the project better.
