As QuEST Forum's TL 9000 Requirements and Measurements Handbooks are deployed and used widely, questions arise from time to time, about the correct interpretation of some of the requirements, application of certain requirements, counting rules for measurements, and more.
QuEST Forum's subject-matter experts review these questions, analyze the situation, and if needed, publish an Information Alert to clarify the issue. These Information Alerts do not constitute new requirements, nor do they place any additional requirements on TL 9000 registrants. They serve solely to make the TL 9000 standard easier to understand and be applied more uniformly.
Obsolete alerts that don't apply to the latest release of TL 9000 or other factors can be accessed under Archived Alerts.
