9 likes1,986 views
This document discusses various metrics that can be used to measure agile processes. It begins by defining what a metric is and explaining common process improvement cycles. It then outlines different categories of metrics including business, process, code, design, testing, and automation metrics. Examples are provided for each category. The document notes that choosing the right metric is important and should encourage desired behavior, be easy to measure, and provide periodic feedback. It emphasizes that both leading and lagging metrics should be considered to measure productivity, predictability, quality, and value.
