Analyzing Elicitation Techniques: knowing the use and challenges to strength the requirements phase

Abstract Context: Requirements elicitation techniques are critical to helping requirements engineers gain a better understanding of the needs of users and stakeholders. Currently, there are many RE techniques, bringing possibilities, but, on the other hand, doubts to the technical team about which to use to correctly extract the system requirements. Question/Problem: This study presents a list of the most discussed techniques in the literature and compare them with the most used techniques in industry. Also lists and categorizes the main challenges of requirements elicitation in software development assisting requirements engineers for the possible problems they might encounter. Complementary, we suggest some RE techniques combinations to help the community to surpass those challenges. For this, we conducted a Systematic Literature Review (SLR) to identify requirements elicitation techniques and challenges discussed either in literature or in industry and confronted the findings. Results: Based on the 43 selected papers, the SLR identified that traditional techniques are the ones most remembered either in the literature discussions or in the industrial projects with some new techniques, such as, Persona and Design Thinking gaining ground. Also, by combining some techniques we were able to overcome most of the identiied challenges. Contribution: We concluded that Interview, Prototyping and User Stories are the most cited techniques and their combination with Design Thinking or Persona could help surpass the identified challenges. In future, we will build a guide to help the software community and improve the analysis testing real world scenario
