Only if you know what your retirement plan is all about, you can say that it is exactly the right plan for you. You also know precisely when you need to adjust it. Everyone needs one if they want to have a nice future. One should know how it works and what benefits you will get in the end. You should ask yourself these questions because they are too important not to be answered. Most of the employers these days offer some sort of retirement plan for their staff, this also means that someone is or some people are responsible for the management of these plans. There are a lot of rules that need to be followed and someone needs to keep the oversight.
Process definitions are high level descriptions instead of rigid workflows : Processes can only be defined up to a certain level of detail, and it is difficult to provide low level work instructions or to automate decisions. Because they cannot be formalised in detail, process simulation is rarely possible. Decisions are highly subjective and too complex to be expressed in a formal language, as they are taken based on intuition and not on rigid business rules.
