ABSTRACT
We conduct secondary studies in order to answer a variety of research questions, so it is not surprising that we need to adapt the way that such a study is organised according to the question being addressed. Some reviews seek to answer questions about software engineering practices (for example, “in what situations is pair programming likely to be a good strategy to adopt?”); others may examine research trends (such as “what have been the ‘hot topics’ in cloud technology research and how have they changed with time?”); while a ‘broad’ form of review might be used to help determine whether a more focused review of a topic is feasible-or whether it is first necessary to perform more primary studies on that topic.
