 We use the term central \emph{RSE unit} interchangeably with the term \emph{RSE hub} even though for large federated research organisations there might be a more complex arrangement such as a network of RSE hubs.

 Research software is getting increasingly complex.
 This is partly because the scientific problems being tackled using software are getting bigger.
-However, the software is also expected to be reliable, secure and easy to use.
+However, the software is also expected to rate high on a multitude of quality metrics such as correctness, reproducibility, maintainability, extensibility, usability, portability, interoperability, security, performance, and scalability~\autocite[Chapter 16]{Schulmeyer2008}.
 Handling this increased complexity whilst ensuring timely delivery requires dedicated RSEs in central RSE units.

 With the majority of researchers being self-taught programmers~\autocite{Carver2013}, there is a huge demand for expertise on how to develop better research software.
-Here, “better” can refer to a number of quality metrics such as correctness, reproducibility, maintainability, extensibility, usability, portability, interoperability, performance or scalability~\autocite[Chapter 16]{Schulmeyer2008}.
+Here, “better” can refer to a number of quality metrics as already mentioned in Section~\ref{sec:motivation}: correctness, reproducibility, maintainability, extensibility, usability, portability, interoperability, security, performance, or scalability~\autocite[Chapter 16]{Schulmeyer2008}.
 
 In order to raise the quality standards for research that is based on research software, it is of great importance for research institutions to provide access to such expertise with a low barrier to entry.
 The hub is a natural place to provide this central service.
