Quantifying Software: Global and Industry Perspectives

Software is a critical product, but it is also expensive and labor-intensive, and its quality is often poor. This reference provides quantified data from 26,000 projects between 1970 and 2017 to encourage the adoption of best-in-class software metrics and technology stacks. The data covers average software schedules, effort, costs, and quality for several industries and countries, and includes information on cost of quality, technical debt, and three years of software maintenance and enhancements.

Software stands as a pivotal product in human history, embraced by all industries and nations alike. However, its significance is accompanied by considerable expense and labor-intensive nature, making it one of the most costly and resource-intensive endeavors in our collective history. Regrettably, the quality of software has been a recurring source of concern, leading to significant disasters and the loss of substantial financial resources. Moreover, software faces relentless and escalating cyber-attacks, further underscoring its vulnerability and the urgent need for robust security measures.

One of the primary contributors to these software challenges lies in the chronic absence of reliable and quantified data. This reference aims to bridge this gap by presenting a comprehensive dataset derived from approximately 26,000 projects across diverse industries and countries, encompassing a range of methodologies and team experience levels. The data spans from 1970 to 2017, offering valuable insights into historical trends.

Given the current suboptimal average software productivity and quality outcomes, this book takes a focused approach, highlighting best-in-class results. It not only presents quantified data on quality and productivity from top-performing organizations but also delves into the technology stacks employed to achieve such exceptional outcomes. The overarching objective of this book is to foster the adoption of best-in-class software metrics and technology stacks. To achieve this, it offers current data on average software schedules, effort, costs, and quality across various industries and countries. Recognizing that productivity and quality can vary significantly based on technology and project size, the book provides quantitative results for applications ranging from 100 function points to 100,000 function points. By employing defect potential and DRE metrics, which are widely recognized as key indicators of software quality, the book aims to provide actionable insights into reducing bug-related costs, which remain the primary driver of software development expenses.

While the book discusses the concept of technical debt, it is important to note that this metric lacks standardized definitions and methodologies. Nonetheless, it serves as a valuable discussion point, shedding light on the potential long-term implications of neglecting software quality and maintenance.

In conclusion, software's historical significance, widespread usage, and immense impact on societies cannot be overstated. However, the challenges associated with software quality, cyber-security threats, and the need for reliable data underscore the critical importance of continuous improvement and proactive measures. By embracing best practices, investing in robust technology stacks, and prioritizing software quality, we can strive to create a more secure, efficient, and sustainable software ecosystem for the benefit of all.
