How to make Rational Unified Process fusion salad

The explanation for what is the Rational Unified Process from Wikipedia free encyclopedia is pretty decent. Wikipedia is this weird project that you can contribute to which I found when trying to learn what some of these achronyms (RUP) mean and their applied uses. Some I knew already like FTE and FPE. Some I have made up myself to move a conversation along(heh he). It is so comical how all this 'applied process theory' though are so much more like a philosophy. Where true gaps exists, and it's no wonder anything ever gets done in this world and no amount of theory is ever going to be replaced by AI. I have been finding that people are mostly affraid to set deadlines/timelines which is ironic as a self proclaimed PM/Producer(talent manager), it's extremely annoying, when you're trying to figure out the next job phase and noboby can commit, they give partial answers, lack of follow thru and or by the time they do, you've moved on to the next pitch, changed focus and even funnier than that, is that is the exact description of a Project Manager's job responsibility, is to manage accountability, expectations, and to manage these exact company issues. There are different grades/types of pms but that is a whole other story.
Simply: I look at process models as a group making a salad. (Yes it's close to lunch time) Everybody is in charge of one part of what makes the end product a salad. Everbody has particular things they like in their salad, or something they are in charge of of for said sald. Yes, the analogies are easy to see, and what makes an awesome salad is when everybody in the team has idea of what the other persons is good at or responsible for and one of those duties is knowing when the salad is ready to eat.
