Which field? In the absence of any constraint, the choice of workflow management system is down to individual preferences. Note that the goal of CWL is to be a standard workflow language not a workflow management system. That is, it is concerned purely by how to precisely describe a workflow, not by how it should be implemented which is the task of a workflow management system. The diversity of workflow management systems starts to be recognized as an obstacle to re-use and reproducibility of scientific workflows. Having different systems implementing a standard language would help get around this issue. Several workflow management systems used in bioinformatics have or are implementing support for CWL.
