Object Process Methodology (OPM) is a way of analyzing and organizing things. It looks at both objects and processes, which are elements that can help us better understand the way a system works.
Objects are the "things" in a system. For example, a fridge is an object. Processes are the actions that happen. For example, the process of putting food in the fridge is a process.
Object Process Methodology helps us organize objects and processes so that we can better understand how a system works. It also helps us figure out what happens when things go wrong. OPM is helpful in many areas, like engineering, business, and computer science.
