Comparison of Focus Group, QFD and Ontology on the bases of Implementation, Applications and benefits in Requirement Engineering

Requirements elicitation technique is the main and important part of any software project. There are hundreds of requirement elicitation techniques, and each technique has its unique characteristics and importance but the point is which to use and which do not use. There are some conditions and scenarios in which particular elicitation technique will be suitable. There are some technique which you not known. We are here to introduce some other elicitation technique. Combination of several technique can result in the clear and collect almost all requirement from the customer, user and stakeholder. The purpose of this paper is to know about these elicitation technique and might be these techniques are best for requirement gathering. In this paper we will discuss the 3 requirement elicitation techniques, their detail, advantages, disadvantages and comparison among the techniques. The three techniques are QFD, Focus Group and Ontology.
