Hello Ian, As always, thank you for the engaging and insightful webinar. I particularly like your approach of looking at a specific topic (in this case SSOW) and then expanding on the subject matter to include case studies and critical research. I was already a big fan of the 'Checklist Manifesto' but I had not come across Gary Klein before. I bought his book 'Seeing What Other's Don't' as a direct result of yesterday's webinar. Can I ask you a question please? In Gary Klein's 'Performance Improvements' model he describes the down arrow as 'errors' and the up arrows as 'insight'. Do you think there's a practical application for applying this to H&S behaviours to capture the 'insights' element? Or is it simply a case of providing a staff suggestions box to the construction site, where people can provide their insights? I think we have robust systems to capture errors, but I'm not so confident about the insight alement. Thank you once again for the webinar, whenever I see your invite, I always do my best to attend because I know it will be worthwhile. Kind regards, David
