Since its inception in the early 1980s, the field of strategic management has expanded greatly as researchers, managers and consultants have worked to develop and apply a knowledge base to inform the decisions of strategic leaders. The Strategic Management Society now includes more than 3000 members and the flagship journal, Strategic Management Journal, receives over 1000 submissions a year from authors all over the world. This developing and expanding knowledge base reflects the complicated and complex business world today that scholars and managers seek to understand and lead. Our field now embraces a broader plurality of research questions, units of analyses and modeling tools. These developments beg the question of whether the foundational questions that drove our field at its inception are still at the center of it, or whether there are new unifying themes that may drive future knowledge creation.
