A Hybrid S/W Requirements Elicitation Approach to Improve Quality of Gathered Requirements

Abstract

The discipline of Requirement Engineering is associated with a great number of problems, starting from the elicitation phase to the implementation of these requirements in the software industry. Although many approaches have been proposed by the researchers, but very small number of approaches are used in software industries. It is known that requirements which are not well understood and unrestricted changes to the scope of requirements lead to numerous software projects failure. So, good requirements are very important for project success. Thesis helps in exploring effective approach for text chat application requirement gathering purpose. The aim of this thesis is to focus on approaches used in software industry for elicitation purpose of text chat application. For this we selected five different approaches of requirement gathering and fixed the number of requirements to eight. We gathered requirements randomly for different people, but we make sure that all of the respondents are familiar with the chat applications. One thing is understood that if the requirements of the system are not best understood then they will lead towards project failure. We gathered requirements by different approaches and checked the requirements with good quality attributes of requirements, the approach that produces high value, considered as the good approach for requirement gathering purpose for text chat applications. Lastly, we merged two approaches and make a single hybrid approach to check the results of requirement obtained with this hybrid approach. These findings need to be demonstrated in the context of this research. We concluded that good results can be achieved by merging the two approaches. In our scenario brainstorming along with interview produces the best results.
