Sure, I'll do my best. My team is designing a new product for our company. We know what we want the end result to be, but we have several iterations to make on our current product to get there, and each iteration can branch through several paths to satisfy our requirements. So there's a hardware tree which lists the options we have to upgrade the hardware, a software tree that shows the scope of options we have to improve the software, etc. The idea is to show the different tasks that need to be done; and which can be done concurrently and which need to be done sequentially to get to our goal. I showed my team the Factorio tech tree to give them an idea, but I didn't realize people used them professionally.
