In complex projects with multiple deliverables, locations, and stakeholders, best practice is to combine individual risk identification (e.g., interviews, surveys) with group-based methods (e.g., focus groups, workshops) to ensure comprehensive risk coverage and diverse input. According to the PMBOK® Guide:

“Both individual and group risk identification techniques are valuable. Combining interviews (individual) with facilitated workshops or focus groups (group) can help identify risks at all levels and build a comprehensive risk register for the overall project.”

— PMBOK® Guide, 6th Edition, Section 11.2.2.2 (Data Gathering: Interviews, Facilitation)

ISO 31000 also recommends a mix of approaches to ensure risks are not overlooked due to limited perspectives.
