A workflow development system is described that provides a developer with a search utility for finding steps for inclusion in a workflow. The system also automatically generates a meaningful name and/or graphical representation for a workflow. The system also provides a graphical user interface that represents output parameters of a first workflow step as user-interactive objects. These objects can be interacted with to cause the objects to be inserted into a data entry element that is used to specify a value for an input parameter of a second workflow step. When executable logic representing the first and second workflow steps is generated, the insertion of the objects into the data entry element has the effect of causing the value of the input parameter of the second workflow step to be defined to include the values of the output parameters that correspond to the inserted objects.
