A method characterized by association of object elements to operational modes is adapted for use during installation or runtime of a software package. In an example embodiment, the software package includes objects and object behaviors, wherein a particular object has at least two different object behaviors associated with the particular object, and wherein different object behaviors are each associated with a different operational mode. The example method includes accepting a signal from a user input device to specify an operational mode in a target system for the software package and determining an object behavior that is associated with the specified operational mode. In one implementation, the determined behavior is installed in the target system while at least one other object behavior that is not associated with the specified operational mode is not installed in the target system. In another implementation, the software package is run via the target system, where the software package implements the determined behavior and does not implement at lease one other object behavior that is not associated with the specified operational mode.
