Poor dependency management can lead to dependency hell, caused by confusion and conflict between dependencies, circular dependencies, and versioning issues that can adversely affect your software, your applications, and your software development pipeline. Without good dependency management, the performance and quality of your software and applications could degrade, and your development pipeline could be impeded. Furthermore, neglecting to manage and update your dependencies could compromise application security by exposing dependencies to vulnerabilities emerging from the use of outdated versions, and the ingestion of malicious packages that can exploit these vulnerabilities. Finally, poor dependency management could prove costly if your software fails, your security is breached, and if your dependency use becomes no longer compliant.
