Not sure how far you got with your assignment or how real it needed to be as a model, but …
You have lots of options ranging from simplistic/manual solutions to fully automated IoT / sensor driven
Linking MS Excel to IFTT is a non-trivial exercise in my mind :-)
You could for example model all of the events in a web based application -
The boat owner could “check-in” and “check-out” the boat from the dock / yard through one view,
The engineer could clock in and out of the job (multiple times) in another view and the same for the quality review.
I would recommend using a database (mongodb for personal choice) to store events and the time at which they happen - then you can use a relatively simple web basedfront end to store and retrieve event data - you could extend this as far as you like with sensors and other cool IoT integrations including IFTTT
Happy to share some ideas with you if this is still a project your working on
