This publication, known as the “Oslo Manual – First Edition”, set out for the first time a consistent framework of concepts, definitions and methodology for the measurement of business innovation, providing guidelines by which comparable innovation indicators can be developed in OECD countries to inform analytical and policy questions. Based on the experience of innovation surveys conducted prior to its publication, the guidelines provided a framework for methodological convergence and international comparability, assisting new practitioners in this field. Whilst initially focused on technological innovation in manufacturing industries, later editions have expanded the scope and guidance of the Oslo Manual.
