  Reproducibility has been consistently identified as an important component of
scientific research. Although there is a general consensus on the importance of
reproducibility along with the other commonly used 'R' terminology (i.e.,
Replicability, Repeatability etc.), there is some disagreement on the usage of
these terms, including conflicting definitions used by different parts of the
research community. In this encyclopedia article, we explore the different
definitions used in scientific literature (specifically pertaining to
computational research), whether there is a need for a single standardized
definition and provide an alternative based on non-functional requirements. We
also describe the role of reproducibility (and other R's) in scientific
workflows.
