Even though \devops is a recent research topic, several studies have performed Systematic Literature Review (SLR) to provide an overview, roadmap and challenges found in \devops. They were pioneers to map the main concepts, the challenges, the research opportunities and the gaps found about this subject.
Several studies thus far have performed Systematic Literature Review (SLR), and they can be characterized by their research questions, the methodology adopted, the literature sources, and, finally, by their findings.
Table \ref{tab:research-questions} depicts the research question of previous SLR works, and Tables \ref{tab:research-methodology} and \ref{tab:reseach-sources} summarizes, respectively,
the methodology and the literature source used in these works.

It is relevant to mention that all previous SLRs had their literature review done before 2015. It means they examined mainly the pioneer researches on \devops (before the increase number of works on \devops started in 2016). As they all mentioned in their SLRs, the quality of the studies in these earlier early papers is quite low \citep{Erich2017SLR}, with confusing/contradictory technical terms \todo{colocar referencias}.
As evidenced in Table \ref{tab:research-questions}, Systematic Literature Review (SLR) on \devops thus far has mostly looked at the significance of the term \devops,
due to the lack of consensus in defining it, even though none of them have proposed a definition that was absorbed by the \devops community.
The second most recurrent topic addressed by previous SLR is the challenge of effectively adopting \devops in organizations \cite{gill2017SLR} \cite{Paasivaara2015LSR} \cite{travassos2016SLR}, the motivation
to adopt \devops and the benefits expected when deploying \devops in their organization. It highlights that the focus of most studies is to understand and to guide researchers
throught the problem of deploying \devops in organizations perspective. From this perspective, these recurrent research questions have converge to some interesting findings.
As evidenced in Table \ref{tab:research-questions}, previous SLR on \devops thus far have mostly looked on basics when looking at their research questions: significance of the term \devops , the motivations and the challenges to \devops adoption. This topics were chosen due to the novelty of the research topic, and fact that there was a consensus that the term \devops was ill-defined, which affects the perception of \devops benefits, the expectations and challenges when deploying \devops \cite{Erich2017SLR}.
When it comes to the first research question, none of SLRs have proposed a definition of the term \devops that was absorbed by the community.
First, the studied literature did not find a final definition of \devops, but they have defined it in multiple ways:

Systematic Literature Review to cover both academic and practitioners perspectives.
