Software Development Productivity Measurement Using LOC and Function Points

Abstract

Software development productivity measurement is important for evaluating how efficiently software teams convert effort, time, and resources into working software deliverables. Lines of Code and Function Points are two common productivity measurement approaches, where LOC measures the volume of source code produced and Function Points measure delivered functionality from the user’s perspective. Traditional productivity assessment may depend only on project duration or team size, but these measures do not clearly show development efficiency, functional output, or effort variation across projects. This article focuses on software development productivity measurement using LOC and Function Points by examining code volume, functional size, development effort, productivity rate, language dependency, project complexity, and estimation accuracy. The study discusses how LOC can support code-based productivity analysis, while Function Points provide a more technology-independent view of software output. The article concludes that combining LOC and Function Point measures can improve productivity evaluation, support project estimation, compare team performance, and strengthen software project planning.
