SHEL Model

The SHEL Model is a framework used to analyze and improve safety in complex systems like aviation or healthcare. It identifies five key components: Software (procedures and manuals), Hardware (tools and equipment), Environment (physical and operational setting), Liveware (people involved), and Liveware-Liveware (interactions between people). The model emphasizes that safety depends on how well these elements fit and work together. By examining these components and their relationships, organizations can identify potential weaknesses and enhance overall safety performance.
