Lessons Learned

Peer Evals

Member Team Feedback Given How I Have Improved
Stephen J. Giordano
  • Balance workload between project management and electrical subsystem.
  • Planned ahead, which helped during the redesign of the system. Was able to take some responsibilities from Kyle, preventing errors from rushed assembly and testing.
Nathan P. Ehnot
  • Make sure you aren't taking on too much of the work. Delegate tasks to your teammates or ask for help when needed so you don't get to stressed.
  • Delegated TVA tuning to Connor and display finishing to Shayne in order to free up time to finish Eng. Req. testing and drawing updates.
Shayne F. Hollands
  • Set aside more time for MSD
  • Set up problem tracking, poster, report
Connor Jensen
  • More communication, especially with non-MECEs
  • Went to EE lab to give everyone a heads-up on the daily plan rather than straight to shop
Kyle M. Kelly
  • Present material in a more clear and concise manner.
  • Took time before reviews to really think about what material I was going to cover, and what level of detail to cover it in. This resulted in less rambling on and time spent wasted thinking about what the next address point was.
Malik Wallace
  • Communicate progress with the GUI, whether good or bad to keep everyone in the loop.
  • Tried to demo the GUI and show off progress when the group is around. Kept Stephen in the loop in regards to hurdles in the GUI.
