Book Series Increasing Productivity of Software Development: In software development, productivity is a measure of how much functionality can be developed in a given time and in compliance with specified quality criteria. If an increase in productivity succeeds, this increases the scope of the developed functionality and reduces the required time. Both features are desirable because software is the stuff innovations are made of. IT has changed almost all areas of life thanks to fundamental innovations. Our future will be dominated by virtualization and smart helpers, that is, devices equipped with intelligence. This makes software development a key competence. Today, for companies that develop software, productivity as well as time and quality, are critical success factors. By introducing standards and automation, productivity in software development has been demonstrably increased by a factor of 20. The reutilization of functional and technical components has already enabled measurements of a factor of 100. Such performance differences are only reproducible by measurements and the consistent use of measurement results within a management model designed for continuous optimization. Part 1: Productivity and Performance Measurement ¿ Measurability and Methods This book describes practical experiences with various measurements in software development: advantages and disadvantages of proven and new methods, their automation, the influence of complexity and the steps towards the implementation of regular measurements.
