Screening processes are systematic methods used to evaluate individuals or items to determine their suitability for a specific purpose. These processes can be applied in various fields, such as healthcare, employment, and security. For example, in healthcare, screening may involve tests to identify diseases early, while in employment, it can include background checks to assess a candidate's qualifications. In security, screening processes often involve checking bags or using metal detectors to ensure safety in public spaces. The goal of these processes is to filter out those who do not meet certain criteria, thereby enhancing overall efficiency and safety in decision-making.
