Configuration and Customization are terms that many use interchangeably and easily without thoroughly understanding the difference between these highly divergent concepts. The act of configuration is modifying the attributes of a product or service for particular use. In economic terms, there is some utility or function which the product or service inherently provides, which is preferred; however, the product, device or service needs to be modified in some way to fit the particular use for the organization or individual.
A simple example of configuration involves a software application such as Microsoft Word. Suppose that there are two individuals who are using Microsoft Word for different purposes. As a result of these different purposes or use cases, one individual requires that the font size of what he or she is typing be Times New Roman 20 pt, while the other individual requires the font size of their document to be Times New Roman 16 pt. Within Microsoft Word, each individual can readily change the font size of the document with great ease between 20 pt and 16 pt font sizes through the simple click of button. This action, by two distinct users can be performed with relative ease and minimal effort. This activity does not require a high degree of technical knowledge of the inner workings of the Microsoft Word application, nor does it require hours of training. The aforementioned trivial example indicates configuration.
