Innersource, a practice where organizations apply open-source methodologies internally, enhances both user experiences and developer productivity by fostering high-quality, secure, and reusable code. By adopting innersource techniques such as creating software templates and facilitating cross-team collaboration, companies can achieve a consistent user experience and boost developer efficiency by up to 87%. A government agency, with the assistance of GitHub Professional Services, developed a portal to help developers discover and utilize reusable software, which significantly improved the quality and security of their code base. This approach, complemented by metrics for monitoring security and the use of GitHub Advanced Security features, led to a 50% reduction in vulnerabilities across their innersource repositories, thereby securing the products and services dependent on them. Organizations can accelerate development by identifying reusable software, making it discoverable, tracking relevant metrics, and taking action based on these insights.
