RIT will permanently shut down the RIT Wiki (Confluence wiki) on February 2, 2024. Review the Wiki Shut Down Overview for information on alternative tools, exporting content from the wiki, and other FAQs.
For phase 4, the team has re-evaluated the risk assessment chart and made some changes. The team has found new risks to add for this phase but the overall importance went down. The team added 2 new risks. Those risks are 20 & 21. There could be issues with trying to use citronella oil and as substitution water might be used. This in turn could not give us the most accurate data as water and citronella are very different and the flow of each fluid could be drastically different. To minimize this risk the team is going through proper guidelines to get permission to use citronella oil. Along with this, the team is trying to find any substitute substance that be could be used instead of citronella oil. The latest risk item that was added linked in Bluetooth mesh failing. This could happen by something happening to the MCU like not getting power or a part is damaged. This in turn could cause the communication between the mesh network to fail. To minimize this risk we have to make sure each link in the mesh has multiple connections so it can find its way back to the master.Risk Assessment
The team has also decided that some risks could get a lower likelihood or severity. Those risks are 4, 5, 6, 10, and 13. For risk 4 during the previous phases, we were worried about dev-kit costs and how that could be really expensive. As the team chose out some dev-boards to use we were able to find them at a cheap cost, reducing the likelihood and severity of spending a ridiculous amount on dev-kits. The next risk that the team thought could be reduced is the market for the product. After seeing the torches and focusing on keeping the aesthetics of the torches we felt confident in this product idea and thought that it would sell well. The next risk that the team thought could be reduced was about covid-19. As vaccines are rolling out and after working for a semester together mostly online the team decided that the severity could be bumped down as it didn't affect our productivity. This leads to our next risk which was the team not being able to meet in person. The main worry for this was about covid-19, but as more things are opening up and the team also meeting a few times in person we felt that it wouldn't be a big risk. The last risk that the team reviewed was the limited knowledge of app development and fluids. The team worked towards learning more about each topic and has a plan on getting the resources to learn about it and felt that it wouldn't cause as big of a problem as we initially thought it would.
A chart with the importance vs the number of risks is shown at the bottom. It shows how the importance and the number of risks changed over each phase.
