\section{The Paper}
-According to \cite{186171}, testing error conditions is critical for robust
-distributed systems.
+Besides other things, \cite{186171} analyzed 198 randomly selected failures in
+popular distributed systems, and classified the reasons for each failure. This
+is one of the most interesting findings:
+
+\blockquote[\cite{186171}] {
+ Almost all (92\%) of the catastrophi system failures are the result of
+ incorrect handling of non-fatal errors explicitly signaled in software.
+}
+
+\section{Structure overview}
+
+\subsection{Kind of study}
+The paper is strategic, applied:
+
+\begin{description}
+
+ \item[Strategic:] authors have developed an artifact \tt{Aspirator} which
+ helps software maintainers find certain classes of bugs. What is more,
+ they provided new knowledge, like in the quote above.
+
+ \item[Applied:] the artifact of the work, \tt{Aspirator}, can be applied by
+ other software developers looking for similar classes of bugs.
+
+\end{description}
+
+\subsection{Purpose of the research task}
+
+The research task is descriptive and correlative: given a well-understood
+situation of distributed systems fail catastrophically, researchers are finding
+common reasons for failures, and developing tools to mitigate them.
+
+Conclusions and suggestions are prescriptive: the researchers are warning
+engineers against common failures, and suggesting tools to mitigate them.
+
+\subsection{Applied Strategies}
+
+The task is mixed:
+\begin{description}
+ \item[Quantitative:] researchers are analyzing and classifying a large
+ number of bugs.
+ \item[Qualitative:] each bug requires careful analysis in order to classify
+ it and make interesting conclusions.
+\end{description}
+
+\subsection{Do findings reflect the purpose and results?}
+
+Research findings are derived directly from the purpose and research results.
+Namely, the researchers set out to find the most common reasons for
+catastrophic failures in distributed systems. They found them, classified them,
+and gave suggestions for future generations of distributed systems developers.
+
+\subsection{Scientific Method}
