If poor quality software produced quickly, may appear to be more productive than if produce reliable and easy to maintain software (measure only over software development phase). More does not always mean better. May ultimately involve increased system maintenance costs. Common measures: Lines of source code written per programmer month. Object instructions produced per programmer month. Pages of documentation written per programmer month. Test cases written and executed per programmer month. �
