System Theoretic Process Analysis (STPA) STANDARD for All Industries
J3307
This document provides a standard definition of the System Theoretic Process Analysis (STPA) methodology for critical applications in all industries. This standard defines the terminology, the steps in the methodology, the flow of activities, and the expected deliverables necessary to demonstrate the expected STPA methodology has been followed. This standard may be used when addressing compliance with contractual or regulatory requirements regarding risk assessments, safety assessments, development assurance, system security engineering, or other similar requirements as appropriate. In addition, this standard may be used to demonstrate that an effective STPA evaluation has been conducted when compliance is not of paramount concern.
Rationale: This standard defines the steps, tasks, and flow necessary to execute a System Theoretic Process Analysis (STPA) system safety evaluation process and outlines the expected deliverables. This document references content from SAE J3187 (2023-01) Recommended Practice and the STPA Handbook (MIT 2018). This document utilizes state of the art STPA methodologies developed and successfully used by expert STPA Practitioners over the past 10 years.
