P16214: Bicycle Power Meter

Customer Handoff & Final Project Documentation

Table of Contents

Continuing on from last phase our MSD team was able to get our device working for our customer, the RIT Cycling Team. Our team displayed our device at ImagineRIT and the exhibit was a success. Our customer was very pleased to see our working device and also to see how accurate the bicycle power meter was for displaying power output of the rider as well as the rider's calories.

Team Vision for Final Demo and Handoff

Our team vision for this phase was to finalize any and all documentation to be able to hand this information over to our customer. Some of the examples of the handoff documentation to our customer are a users manual and finalizing all test data for the customer to see the tests that were completed for the device and how accurate the system is to other power meters that are manufactured.

Test Results Summary

After completing our bicycle power meter our team had decided to test the accuracy of our system with respect to a manufactured bicycle power meter. The manufactured bicycle power meter provides the user's output power data within 1% accuracy of their actual power output. Our team tested our power meter against the manufactured power meter over a time of five minutes and recorded the output power and the overall calories burned every 20 seconds over the five minute period. After conducting the test our team saw the following results:

The image above shows that as the rider pedaled for five minutes and changed their power output the MSD team bicycle power meter was very accurate with respect to the manufactured power meter. The bicycle power meter was most accurate when the rider produced a steady constant power output. The Full System Test Results Spreadsheet also shows that the total calorie count was accurate to 1 calorie after five minutes. These results were within the accuracy range that our customer wanted to see and our team was very happy with these results.

Risk and Problem Tracking

After the ImagineRIT exhibit our MSD team decided to revisit the risk assessment document. The following image shows the updated risk assessment:

Updated Risk Assessment

Updated Risk Assessment

A link to the original and live document can be found in the MSD II Documents folder. After ImagineRIT the likelihood of most of the risk items were changed to a 1 because it was proven that our power meter worked correctly and met all of the requirements.

No new problems had arose since the last phase of this project and all of the problems had been solved in the previous phase. For this reason the problem tracking document has not changed and is the same as during the previous phase.

Final Project Documentation

As our team completed our project and had produced a fully functional bicycle power meter, we had created documentation to support our testing and design decisions. The following are links to the documents that our team created to support our findings and our total project journey:

Functional Demo Materials

As a final review of how our team did to meet our customer requirements we created a document to show how our device performed for each customer requirement. The Performance vs. Customer Requirements Document shows how our bicycle power meter performed against each of our customer requirements.
