Tracking recent milestones in the ideas that constitute organizational strategy helps to archive strategic thinking and gets us closer to strategic choice. It is also understood that strategic thinking and social reality interact mutually, and this interaction is central to the emergence of new ideas. These recent ideas of strategy which survive through use, can be viewed as milestones. Four broad milestones have been identified through papers and cases: emergent missions, emergent forms, emergent resources, and geographic locus.
