I think the real change in Health and Safety in recent years has been the focus on behavioural safety and I think this is what you mean. It's cultural change you need right?
One of the outcomes of behavioural safety initiatives in one place I worked in was to encourage all managers to talk to someone every day about safety. This could be positive or negative. We brought in a very similar system at the same time for food safety.
Have I brought in this system at my new employer? No. Not yet. We're a way off that for a start and secondly, the system which was insisted upon by my manager was unwieldy and it was just another tool to hit people with in an antagonistic work place. That all said, some people used it really well and by 8 different people having a conversation about food safety and quality with a person on the shop floor (of about 60) that meant within an average month, each person would have been spoken to more than once. Imagine the power of that? We passed BRC that year btw with only 2 minors...
So this is something I will be bringing in soon. I may face some rolling of eyes mind you.
For me, changing quality cultures is not about snappy catchphrases and I agree with all the PP, yes all of those things help but, in the end, you need a way to make quality / food safety part of the fabric of your site like H&S should be (and is in many workplaces nowadays). H&S is very rarely a one person job nowadays. Most managers accept it's part of their remit and this is one of the ways to drive that ownership with quality and food safety.
