The proactive identification and analysis of such SCTs has improved in recent years reflecting increased awareness and acceptance of the value of looking at such activities in detail, using the SCTA process. This growth is due to: significant uptake of the first edition of this guidance; the recognition that purely technical approaches to safety have their limitations, and through ongoing regulatory support.
