This would be an example of developing an "operational definition."
An operational definition, when connected to information collection, is an unmistakable, brief meaning of a measure. The requirement for operational definitions is principal when gathering a wide range of information. It is especially imperative when a choice is being made about in the case of something is right or mistaken, or when a visual check is being made where there is space for perplexity.
When gathering information, it is fundamental that everybody in the framework has a similar comprehension and gathers information similarly. Operational definitions ought to along these lines be made before the accumulation of information starts.
