A collaborative development environment (CDE) is a type of software platform that supports distributed software development by providing a shared online workspace. It enables project stakeholders to collaborate in real time or asynchronously, facilitating communication, documentation, and the coordinated production of deliverables. CDEs are designed to overcome the challenges of working across different time zones and geographical regions by integrating tools such as version control systems, issue tracking, discussion forums, wikis, and code review mechanisms. The term was coined in 2002 by Grady Booch and Alan W. Brown.
