Research question
Seven effects caused by SRAs increased their belief values after the aggregation. These effects have greater confidence value that any effect before aggregation (i.e., greater confidence level than 40%), and have been reported by at least three out of the five studies

As a result of the aggregation process, several benefits of SRAs have considerably increased their belief value: interoperability of software systems, reduced developments costs, improved communication among stakeholders, reduced risk due to previous experiences, use of best practices, and reduced time-to-market. Regarding drawbacks, the studies agree that an SRAa SRA weakly negatively - negatively influence the required learning curve for developers before they could construct software systems.
The aggregation also identified three effects of SRAs that were contradictory in the literature: SRA complexity, flexibility of suppliers, and terminology conventions. We have analyzed the context of studies that reported these results, and elaborate hypothesis to explain these contradictions.
