Team Vision for Build & Test Prep Phase

During this phase of the project our team hoped to regroup from break and begin working to build the prototype of the system that we designed. We hoped to successfully acquire all of the raw materials for the main portion of the build, and establish a workspace for the team. A stretch goal for the team during this phase was to begin cutting our material according to the design specifications, and to submit our water jet files for manufacturing.

We were able to successfully accomplish these goals with the exception of the workspace as the MSD office is struggling to find a suitable location for the team to work. We have acquired a storage locker for raw materials but are currently hoping to find a location for the finished prototype in the next few weeks.

During this phase our team was also able to establish that we do not need a budget increase at this time, and have found suppliers for materials that will allow us to maintain the $500 budget given in the beginning of the project.

We were also able to successfully achieve our stretch goal to begin cutting raw materials, as parts began being cut to final lengths on 1/21.

Finally, during this phase our team members completed the human testing training required for our human test plans to be considered by the IRB, and established a rough schedule for the remainder of MSD 2.

Below is a summary of the accomplishments of the team during this design phase

Test Plan Summary

As previously established, the team developed test plans for various conditions we hoped to prove in our design. As we move through the build phase we hope to test the conditions as outlined in these plans. This will occur in phases as the various subsystems of our model are built.

Human testing will occur only under the condition that the human test plan is approved by the IRB. All test certifications were submitted on 1/21 by Christina Ekers, and the team is currently awaiting approval for these plans.

Upon approval and satisfaction of all other test conditions, the prototype will be tested by team members to finalize the designs suitability for use.

The team will carry out the majority of tests in the workspace that will be provided by the MSD office with the exception of the weighted lift test. This test will be completed in a secondary location TBD.

Risk and Problem Tracking

Upon completion of MSD 1 the team was able to come up with 75 total risks throughout the duration of the semester. Of these 75 risks, 10 risks were realized, and problem tracking process was established. As of current, problems the team is concerned with include:

The remaining problems have successfully be closed out, but that does not mean that they will never show up again.

A sample of the problem tracking document can be seen below, and the full document can be seen by clicking here.

Moving into MSD 2, the team has established 61 carry-over risks, and 21 new risks we will need to manage. The carry-over risks could potentially happen during this semester.

Plans for next phase

The team has established that by the next design review we would like to have 90% of the build materials cut and fabricated. We are hoping that the majority of the system base will be built, and that the water jet parts we have designed will be cut.

Early in this next phase we hope to establish a manufacturing schedule with Gary, and begin the Water Jet process so that we may have a system base assembled by the end of week 6.

Below is a schedule of events the team hopes to accomplish by the end of the next phase.
