Workflow Manager provides a means to create and execute processing workflows, graphically render log data, manage data, and more. WFM was designed to be flexible and extensible. The workflows, which provide for a high degree of automation and standardization, are usually designed, and maintained by subject matter experts (SME). Users can modify them to suit specific local needs and create their own. While most applications are developed by professional software developers, users can extend the system by adding their own programs. The latter is mainly done by scientists for new tools and algorithms and by SMEs for new analysis products.
