Team Vision for System Level

During this phase the team planned on integrating the complete system on-site and verifying the operation of the whole system. The plan for testing was to test each subsystem against the engineering metrics that pertain to the subsystem. This method would thoroughly ensure each engineering metric was tested and that each subsystem was tested in full for each of the engineering metrics that pertain to the system. Although limitations restricted the amount of testing that was able to be completed, the team was able to meet and test on site for one week, during which the majority of the new system was installed and tested. The completed testing showed significant signs of ergonomic improvement in the system.

The team also planned on having an on-site presentation of the fully operating system. Although the team was unable to completely integrate and fully test on-site due to unexpected constraints on the customer side, the team continued to verify completeness and thoroughness of final deliverables. The team further developed the SolidWorks drawings for the adjustable WIP stand, the kink tooling, and the extended tooling connector for the operator tooling. In addition, the team worked to develop the technical paper and ImagineRIT poster.

Test Results Summary

The team completed off-site testing for the subsystems in which the team had access to. This included the WIP tile tests for display pattern, quantity of WIP, and angle of the stand. Additional review of the PDF stretch and exercise sheets was completed by SMEs to verify the effectiveness and benefit to the operators of performing the stretches.

When the team was able to test on site, more subsystems were available to test. The viewing system and operator tooling were tested by the team members as well as the operators. The armrest and switch for the actuator were not installed yet so they were unable to be tested.

Through the initial testing on-site the team was able to work with the operators and gather their feedback. Although much of the feedback was shared to the team verbally by the operators rather than through the initially planned follow-up operator survey, the team took note of this feedback and was able to conclude that there has been significant initial improvements in the ergonomic set up of the workstation. One operator had said “Usually after about two or three parts my shoulder starts to hurt and it gets tired, but I’ve done about a dozen parts and I’m feeling fine!” We recognize that this comment was made really early in the testing but it shows that the operator is open to the changes and is excited to work with the new set up. We hope her positive experience is shared with the other operators and the excitement for the new system grows as they each get a chance to use the new system.

Risk and Problem Tracking

As the project progresses the initial risks associated with design challenges and part delivery were eliminated. The remaining risks are related to final verification of the system as a whole. To compare, at the start of the phase there were 30 open risks and 16 closed risks, while at the end of the phase there were 15 open risks and 31 closed risks. The significant transition was due to the testing and the remaining risks are related to the operator safety over the lifetime of the system, which we are unable to measure during MSD II, and the final close out of the project.

Functional Demo Materials

The list of final deliverables to be provided to Micropen for the customer hand-off will be used as a checklist to verify that each of the agreed upon deliverables are provided to Micropen for the customer hand-off. The “Delivered” section will be completed after the customer hand-off review and prior to the final presentation.

Plans for next phase

Between the customer hand-off and the final presentation the team plans to finalize the Technical Paper for the course, actively participate in ImagineRIT, and follow-up with Micropen to ensure customer satisfaction of the deliverables provided.
