Knowledge workers carry out these processes by taking into account multiple inputs (generally a wide set of unstructured data and information) to perform difficult tasks and make complex decisions among multiple possible ways of doing the work, each one implying different levels of risk and possible benefits. They are dependent on individuals and it is not possible to automate them. One example of a knowledge process is "Marketing a new product". The same steps are followed each time a new product is launched (benchmarking competitors, deciding pricing strategy, planning promotion, etc...), but it is the experience, knowledge and intuition of the people that drive the process to success.
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.
