Systems, methods, and other embodiments associated with business process diagram (BPD) component analysis are described. One example method includes accessing a BPD having a BPD component for which a mapping to a business process execution language (BPEL) component is to be automatically produced by a computer. The example method may also include detecting a join gateway in the BPD. The example method may also include manipulating the mapping to identify that resolution of the join gateway is to be determined by gateway resolution upon determining that the join gateway is not going to receive a loop back edge.
