Process Control Example. An example about heating up of a room temperature which is a process that has the specific, desired outcome to reach and maintain a temperature (e.g. 20°C) defined by you or a person inside the room and should be kept constant over time. You can always change the setting from time to time depending on what your body ...

will be very di–cult to operate without the aid of process control. Nevertheless, it can be worthwhile to spend a few minutes thought on why process control is needed. In the following, a short and probably incomplete list of reasons for the need of process control is provided, but the list should illustrate the importance of process control ...

What is Process Control? " Process control is the act of controlling a final control element to change the manipulated variable to maintain the process variable at a desired Set Point. A corollary to the definition of process control is a controllable process must behave in a predictable manner.
While the application of principles in a flexible process is the key, the following sub-section describes a sequence of key steps in a participatory development process. These steps are not prescriptive, but they rather describe the usual stages that most communities go through during a versatile process of community development.
