Human factors (HF) integration is essential at all stages of a project lifecycle and experience has shown it is ineffective to address human factors issues as an afterthought. HF integration involves applying a systematic and scientific approach to the identification, tracking, and resolution of issues related to human-system interactions. Effective HF Integration ensures the balanced development of both the technological and human aspects of a system and delivers the desired safety and operational capability.

The purpose of this guideline is to assist organisations to improve the implementation and effectiveness of HF Integration into projects by providing guidance on scaling and managing HF activities across a project lifecycle.
