Validity is defined as the strength of any proposition or a conclusion given after conducting research. Validity also means the best of the available approximation that approaches the truth or false results of a proposition. Reliability can be defined as the consistency of a given measurement. It can be a result of a degree that any measuring instrument used in the same manner as before each time the process happens and under the same reliable conditions and with the same subjects gives the same result.

The important concepts in any research conducted are the solutions that one gets in order that certain problems can get reliable and lasting solutions. Moreover, these concepts should be reliable, i.e., they should give a result that is closer to the relationship of the needs of the organization. Also, the concept affected should be valuable such that the solutions will help build a lasting solution to the organizational needs.

Validity can be categorized into different types, for example, construct validity is aimed at determining the relationship of the concepts that an organization is operating on, to the actual relationship that is being studied in the organization. The other type is external validity; this kind aims at generalizing the results of the study to the other surrounding settings similar to the studied.

Reliability can also be categorized into different types for instance: the inter-rated reliability is aimed at accessing the degree of different types of raters who give different estimates from the same phenomena. The other kind is the parallel form of reliability; it is normally used when accessing the consistency from the results of two tests that have been conducted in the same manner from the same field.
