The Gantt chart, shown above, represents the remaining five activities left in the project. I chose to exclude activities that are already past.
Final BOM
The bill of material is 99% complete. I have left this activity up on the schedule because there is a chance that I will have to purchase more parts, specifically a relay module. This will be verified during the Testing phase.
Electronic Assembly
The electronics will be assembled first without the mechanical components in order to test the functionality of the product. This includes the Arduino board, LEDs, Heart rate sensor, and relays. I have allocated 2 days to complete this activity.
Testing
The testing portion will consume the majority of my time. I’ve never used Arduino before, but I’m unreasonably confident that I can pick it up quickly (unknown known). One thing I will need to test for specifically is the switching speed of the relays. If the heart beat is high as 120 bpm, I’m not sure that the relays can switch fast enough (known unknown). I have allocated 7 days to complete this activity.
I’ve also read some reviews on Amazon, stating their Arduino didn’t work properly. I have to leave enough time to reorder some of the components (unknown unknown).
Mechanical Assembly
Once the electronics are verified to be working, I will assemble everything else, including the valve cam cover, the plexiglass back plate, and the mounting of the LEDs. I have allocated 3 days to complete this activity.
Presentation
I will have to remember to leave time to put together the documentation and the presentation. I have allocated 2 days to complete this activity.
Overall, my schedule is pretty tight. I will require 14 days to complete everything. If I need to multiply this estimate by 7, I will require just over 3 months to finish everything properly, which puts the completion date to around July if I work on this everyday. Hopefully, the Rule of 7 is something Dr. Hertzberg made up so we don’t procrastinate.

I really like you Gantt chart, it is really easy to follow and I can get an idea of where you are in your project as it progresses. I think you may have underestimated how time consuming the documentation phase will be, but other than that, it looks like you’ve got this project timeline really well planned out. Great job, can’t wait to see this come to fruition.
Hey Shohei,
That’s one cool Gantt chart! Looks like you found the same source as me for how to make a Gantt chart. Congrats on having your BOM 99% done, that’s a good place to be right after break. I like that you’ve left time for things you know you are unsure of. I would recommend doing the hardest thing first, because it might be less stressful that way. Also, I think that Dr. Hertzberg would loathe the assertion that she made up the X7 time constraint, since she promotes attribution so much!
