Abbreviated as ECS, Enterprise Collaboration Systems is a type of information system (IS). ECS is a combination of groupware, tools, Internet, extranets and other networks needed to support enterprise-wide communications, such as the sharing of documents and knowledge to specific teams and individuals within the enterprise. Some examples of enterprise communication tools include e-mail, videoconferencing, collaborative document sharing, project management tools and others. The objective of an ECS is to provide each user with the tools for managing communications, documents and other information that individuals need to manage their own tasks efficiently in their departments.
