Human factors play a very essential role in software engineering. Human factors must be included in a decent safety management system and can be inspected in a comparable method to any additional risk control system. But, in the last decade, human factors have been disregarded in the fields of software engineering and in the later stages of development as well. Moreover, this area has been overlooked by the scholars and researchers as compared to the other fields of business in which their most concern is with the customers. Moving from the pre-planned to the agile process of development, there is going to be further involvement of human factors according to researchers. This research will find out why Human Factors is essential in Software Engineering. Also, it will determine and apply the data and information regarding the human behaviors, limitations, abilities and characteristics in designing the systems, tools, tasks and active human use.
