A Systematic Mapping Study on Process Improvement in Software Requirements Engineering

Software analysis is the process carried out to obtain requirements that reflects the needs of a client's stakeholders and that allows the construction of a software product that meets their expectations. However, it is also known as a process where many defects are injected. In this context, although process improvement has contributed to the software industry, in the case of software requirements it needs to be studied to determine the improvements obtained and established models. In the literature reviewed, a similar mapping study with 4 research question was identified and used as a reference. The objective of this work is to structure the available literature on process improvement in the software requirements engineering (SRE) domain to identify the improvement phases, paradigms, principles, and established models. For this purpose, a systematic mapping study (SMS) was carried out in the most recognized digital databases. The mapping carried out recovered a total of 1,495 studies, and after the process, 86 primary studies were obtained. In this SMS had established and answered 13 research questions. The different models that are applied throughout the software requirements engineering process were identified, and accepted studies were classified and findings on SRE process improvement were collected. The most used models are CMMI, Requirements Engineering Good Practice Guide (REGPG), and ISO/IEC 15504. Also, 62% of accepted studies are of the proposal and evaluation type; that is, they propose a framework and study the implementation of a proposal in one or more case studies respectively. On the other hand, it was found that most of the studies focused on the process improvement analysis phase. Likewise, in contrast with a previous study, proposal and validation type of studies increased in 9 papers each one from 2014 to date. This shows the interest of the scientific community in this domain.
