Systems and methods for defining a form navigational structure associated with at least one node in a process flow may comprise selecting a node form for the at least one node in the process flow, the node form identifying a plurality of displayable forms. Furthermore, the systems and methods may include defining a plurality of node steps for the node, each node step corresponding to a displayable screen associated with a subset of the plurality of displayable forms. Moreover, the systems and methods may include establishing a hierarchical tree structure associating the plurality of node steps, branches in the hierarchical tree structure having associated validation rules.
