Team Vision for Build & Test Prep Phase

What did your team plan to do during this phase?

Our team planned to get organized as we move into building and testing of our modular shoe. By ordering miscellaneous parts, talking over teardown from MSD I, and setting up our workbench we are preparing so that we will be ready for the next phase.

What did your team actually accomplish during this phase?

We were able to order a sewing machine for sewing the upper of the shoe material when the industrial design space may not be available. The team met with the customer and set up a standard meeting time for the remainder of the semester (Thursdays around 10AM). We also ordered instamorph for morphing the mechanism to the shoe and knives to cut the materials more effectively. We redesigned the mechanism with a dovetail in mind and are working to print it at the end of this phase. We also developed more structured test plans, identified new risks, and were granted a new bench space. Additionally, we talked over a new logo design and will look to present it for Tiger Tank and Imagine RIT.

Test Plan Summary

Test plans have been developed using engineering requirements, along with the given customer requirements when necessary, we developed test plans to quantitatively analyze user comfort, sole switch time, cost per one pair of shoes, outsole cure time, topsole fabrication time, and water resistance. Topsole fabrication time and outsole cure time will be simple estimations based on initial prototyping time. Cost per one pair of shoes will be based on the cost of materials used in one total pair. User Comfort will be analyzed using human volunteers rating on a visual analog scale. Sole switch time and ease of use will also be tested with these volunteers. These tests will give us vital estimations of production time and strength of our product.

Risk and Problem Tracking

At the start of the new semester, the team was bombarded with new risks that we had not previously considered. Below, you will be able to find the newly added risks to the Risk Matrix. The live, full spreadsheet can be viewed here.

Specifically, the risks that were added are related to specific events that occured within the phase period. “Team Member Illness” was highlighted due to both the nature of the Spring Semester wiping out students from classrooms and a member of the team contracting strep throat. It came to light that we had not included it in our first list of risks. Obviously, the route around this risk happening is making sure to take your vitamins, drink your water, and avoid any possible contact with those who are already sick.

“Track & Field Meets” became important this semester due to a member of the team being an active member on the RIT Track & Field team as a thrower. While we are quite proud of him for maintaining this very important balance, we had to add this as a risk since he will be travelling on occasion and this could potentially get in the way of both individual and team work.

An obvious one, “Inclement Weather” pertains to the lovely Rochester weather and it’s every whim. While President Munson has started to get a handle on the weather machine, inclement weather can occur. This includes poor road conditions, the University being closed, being plowed in your driveway, etc. If this should happen during a meeting time, the team members have agreed to do some remote work via use of laptops and text message collaboration.

We added “Item Misplacement” due a series of events that resulted in team members not being able to transport themselves to and from important locations relating to the project. This also pertains to project materials as the items we are using have been purchased used our team’s money that has been allotted through the team’s budget and may not be able to be replaced due to budget constraints.

Updated Risks

Updated Risks

Regarding the risks that have manifested themselves as genuine problems, the Skreppa team has been working diligently to keep track of any problems that arise from here on out. As of mid-January, the problem tracking document looks like the image you see below. The live spreadsheet, that will be updated throughout MSD II, can be found here.
