Improving the Reliability of Function Point Measurement An Empirical Study October 1991 Classic Reprint

This book delves into the concept of function points (FPs), a user-centric, non-code-based metric for quantifying the size and complexity of information systems. It explores the challenges of FP measurement reliability, identifying the primary sources of variation in counting practices. The author examines the evolution of FPs, highlighting their growing acceptance and adoption in the industry. By analyzing detailed case studies, the book quantifies the impact of different counting interpretations on the overall FP count, shedding light on the potential pitfalls and areas for improvement. The research presented in this book provides valuable insights for organizations seeking to enhance the reliability of their FP-based measurements. It emphasizes the need for clear and consistent counting standards, open communication, and ongoing research to address emerging issues. Ultimately, this book underscores the significance of accurate and reliable FP measurement in enabling effective planning, control, and evaluation of software development projects, contributing to improved productivity and quality in the field of information systems.
