The NEA (Nuclear Energy Agency) initiated a joint project named `Good practices for investigators on identifying HOF issues from event analysis processes' in 2022. The overall goal of this project is to compile a catalogue of good practices that are useful for identifying HOF issues during the event investigation process. To this end, project members from 17 countries will collaborate to deliver a series of cooperative activities over four years. The objective in the first year of the project (2022) was for project members to identify a list of detailed questions that captured practices related to the identification and analysis of HOFs in event investigation processes. These questions were distributed in an electronic survey to capture the current state-of-practice in different countries. The purpose of this paper is to outline how the list of detailed questions were determined.
