MSD II: Project close-out

Current State of the Project

Actual Performance vs. Requirements

The spreadsheet below shows the performance of our final project versus the initial design requirements. Unfortunately we did not get to test many of the things we originally wanted to.

How robust is your final design?

While our final design does have some flaws, it is quite a robust project and should be able to stand up to normal operating conditions. In some senses it is actually too robust as it weighs a lot more than we indented due to the thickness of a lot of the steel components.

Did you meet your project budget?

We did not meet the budget we were given, but we knew that would potentially be the case going in. We were only given the $500 starting from the Senior Design Program and $500 from an ASTM Grant. Our customer did not provide any more funds directly, however they did help a ton with acquiring components and machining of components.

Was customer satisfied?

Our customer was very satisfied with our work. I think we exceeded expectations in some ways and the things we missed the mark on are fairly easy fixes.

Comparison of current and original project plan/schedule

Our scope of our project changed a bit in MSD I but was fairly consistent with MSD II. We mainly limited some testing and removed a few small things (like filtration) from our system. Our schedule was constantly changing during MSD II. This was due to a variety of issues encountered with dealing with vendors, obtaining things from our customer, general inability to communicate with our customer at times, personal life setbacks to the group, and more. I think a big thing we learned as a group was to work in parallel instead of series. If we had an issue with getting a part from our customer we should have found an alternative and when looking to obtain a component, reach out to several vendors simultaneously instead of picking just one to start with.

Review Individual Team Member Status

For the most part all team members contributed to the project and got their responsibilities done. We did run into a few issues throughout the semester but nothing that we were physically unable to work through. Our MSD II plan may have been a bit too optimistic. Our time scale was very off as we planned to begin drawings and production week 1 while in reality this did not start until the half way point in the semester.

Risk Assessment and Problem Solving Status

Our most important risks were either mitigated/solved, we have a plan in place to have them fixed in a future design, or they ended up outside the scope of our final deliverable. There were some design issues that we did not anticipate but we already know how these could be fixed.

Looking Forward

Lessons learned

Most of the lessons learned from this project were covered above. While on the one hand it is good to have an optimistic schedule (as when you inevitably fall behind you are at least not in too bad of a shape), sometimes it is tough to always feel behind when you set an unrealistic schedule for yourself. As mentioned above, be self dependent and when you run into a road block think on your feet and find a way around it. Working in parallel and exploring as many options as possible at once is the most efficient way to arrive at an answer the quickest. Communication with your team is key as well as everyone taking on an equal amount of work. I think the biggest challenge we faced in MSD II was having some members putting in overtime while others were unable to work for various reasons.
