The PCM of a vehicle is the brains behind the power. It is an electric circuit board that operates everything from the car radio and air conditioning to the transmission and fuel delivery.
The procedures included in definitions should be repeatable by anyone or at least by peers. An example of operational definition of the term weight of an object, operationalized to a degree, would be the following: weight is the numbers that appear when that object is placed on a weighing scale.
Operational Definitions: Operational definitions define an object, event, variable, concept, or construct in terms of the specific processes, tests, and measurements used to determine its presence or quantity. Operational definitions transform theoretical definitions into observable events. This is because an operational definition states which characteristics will be measured in the assignment of a value to the concept or construct under study. Operational definitions form the basis for the research questions, hypotheses, and the theories associated with the research.
