Despite the continuously increasing importance of Agile and Lean in software development, the number of studies that investigate Requirements Engineering (RE) related aspects remains low. In this paper, we report the results from a literature review about Agile and Lean requirements engineering. By performing a systematic mapping literature review, we identified 22 metrics in 18 publications. We analyzed the identified papers based on research methodology, rigor and relevance and other external attributes. We also map the identified metrics on the abstracted model for Agile and Lean development. We conclude that requirements-associated metrics are underrepresented in the literature and most of the metrics focuses on the time aspect rather than the quality aspect. © 2017 Copyright is held by the owner/author(s).
