Everything comes to term, dies, mutates, evolves, transforms. A person, an idea, a business enterprise. We call this the Stages of an Enterprise Model. The stages themselves can be modeled. They are reasonably uniform with defining characteristics. Exactly when each stage triggers and what the consequence will be is not predictable - the complexity is too great. The environment alone, in which the stage is reached, can make what seems like an easy and straight forward transition into something completely unexpected and an enormous surprise.
