All individuals within business organizations operate as end users. In particular, being end users of the system, the hold with them business information and knowledge that the information system personnel require in order to cultivate and advance all of the elements of the design of the information system. Taking this into consideration, it is imperative for every individual within business organizations to have a basic understanding of the system's development process as their input is fundamental to the design of an efficacious information system (Rainer et al., 2013).

Open Source Software
