The importance of software sizing

ISBSG data is an indispensable asset for organizations that employ Functional Size Measurement (FSM) to assess software development efforts. It provides a rich source of real-world project data, facilitating accurate benchmarking and helping organizations gauge the effectiveness of their FSM practices.

By leveraging ISBSG data, companies can refine their FSM methodologies, make data-driven decisions, and streamline software development processes. This enables them to enhance productivity, reduce risks, and optimize resource allocation, ultimately leading to higher-quality software solutions that meet user needs while controlling costs.

ISBSG data is the cornerstone for achieving excellence in FSM and driving competitiveness in today’s dynamic business environment. ISBSG has published many free resources on this topic, please check them here: https://www.isbsg.org/category/sizing/
