We have a fantastic Multimedia career tech program in the district in which I teach! The kids are motivated, enthusiastic learners and I frequently see them out and about in our building filming. However, this puts a tremendous strain on our teacher to keep track of all of the students and the program's equipment. He must be sure that the many and varied pieces of video equipment are available when students ask to use it. He came to me last year to see if I would develop a reservation app so that all of his students could see when the equipment was being used and then allow them to reserve any piece of equipment when it was available. Instead of spending a month or longer developing that app; I created the Workflow below in about 30 minutes and had all of the students set up and using it within a couple of days. It was quick to make and deploy. I was able to efficiently solve my colleague's issue and now video equipment usage is one less thing he has to worry about. This Workflow could easily be modified for your classroom for any communal classroom supplies or space.
