We run risk-based approach workshops with the people who have to live with the result. A generic assessment is written to cover everything and therefore says very little about the job in front of the team, so we work through your own work areas, hazards and controls until the assessment describes that job — and until the crew can say which risks are theirs to manage and which controls they are actually relying on.
The same format carries the learning after an incident. An investigation produces causes; a workshop is what gets them to the people who were not there, in the words they use on the job.
Best fit: teams working from inherited or generic assessments, HSE managers rolling out a new method, and lessons-learned sessions after an incident.
