the processor coupled with the user interface and the memory including the database, wherein the processor configured to:
determine a minimum set of process engine components needed to perform the process application, wherein the determining further includes:
analyzing a process flow associated with the selected trigger and one or more activities to identify process engine components associated with the selected trigger and one or more activities respectively;
determining that, based on the analysis, at least one process engine component of the identified process engine components is not invoked by the process application at runtime, wherein the at least one process engine component is associated with at least one activity of the selected one or more activities, wherein an input of the at least one activity is not output of any of the selected trigger or one or more activities preceding to the at least one activity;
removing the at least one process engine component from the identified process engine components to form the minimum set of process engine components; and
compile the process application into an executable code that includes the determined minimum set of process engine components.
