I am also working on a capstone project where seemingly minor details have manifested into critical issues that impede the progress of the overall project. This is certainly something that has to be accounted for. One of these issues is contacting suppliers. We received the wrong part for one of our pinch valves and could not finish our preliminary model in time. We learned that procurement is a critical bottle neck that must be accounted for. This gave us a better understanding of these minor details and we adjusted our schedule accordingly to account for other details that may account for more delays.
