11 . The method of claim 5 , wherein the individual determinations the respective assignments for the plurality of actions further comprises:

determining an assignment of third one of the plurality of actions to a different computing resource; and

causing execution of the respective action code for the third action according to the assignment to the different computing resource.

12 . The method of claim 5 , wherein the individual determinations the respective assignments for the plurality of actions is based on a computing resource capability determined to be provided by the same computing resource.

13 . The method of claim 5 , further comprising displaying, via an interface of the workflow management system, the respective assignments of the plurality of actions to a computing resource, including the assignment of the at least two actions to the same computing resource.
