What changes when people do this work.

These are not reviews of a training day. They are descriptions of a shift in how people think.

“What this training did for me was help me acknowledge that — as training agencies, instructors, and people who care about the people they work with — we owe it to each other to take a step back from our own biases and preconceived perceptions. We owe it to each other to identify the limits of our understanding, respond rather than react, and consider that perhaps we can make a difference for another person simply by being open and showing empathy. This training gave me hope that we can change the culture.”

“The fact that a seasoned, full-time occupational dive safety team — responsible for a programme involving incredibly challenging, complex and diverse operations — gleaned as many insights as we did says a lot. This programme should be incorporated into all levels of training, from the most junior through to senior leadership.”
Mauritius Valente Bell

“The course allowed our Public Safety Dive team to come together as a true team. We learned we can grow and accomplish far more when we listen to each other's ideas and have input from all members of the team. We learned to shift our focus from 'why they did that wrong' to 'why it made sense for them to do it that way.' We are a better team today than we were before the course — and all without hitting the water.”

“I went for it head on believing I know what to expect and that l am prepared for it. I couldn't be more wrong about it. If you go Yoga it will let you learn about muscles joints and other parts of your body you are not aware of using or being present. This training does it to me on mental, self conscious and team awareness level. There are things in life you can not go back from, that are forever perspective changing. That one of those. Thank you all for the input. Thank you Gareth Lock for running that and all that you have taught me.”

“As a member of a senior leadership team, I found the course an eye-opening and invaluable insight into how communication, teamwork and solid leadership skills can mitigate risks and ensure a safe and effective working environment.”

“The best presentation I have been to on safety. Engaging, enlightening, and challenging. Really brought the topic to life.”

“Before this programme I thought I understood why diving incidents happened. Afterwards I realised I had been looking at the wrong thing entirely. The shift in how I now brief, debrief, and respond when something goes differently to the plan is not subtle — it is fundamental.”

“We have had safety consultants before. Gareth is not a safety consultant. He changed how our entire leadership team thinks about what an incident actually tells us. Our near-miss reporting increased by over forty per cent in the six months after the programme.”

What others have said about the work that is done by Gareth Lock, and the Human in the System team.

“This course is absolutely amazing. It has completely flipped my perception of performing in a team. I wish I'd had this course while I was playing college sports. This course attacked how I communicate, lead and — most importantly — participate within a team dynamic. I recommend this course for anyone who may need a boost in leadership, communication or teamwork.”

“This course helped build the foundational knowledge of human factors needed to better manage our operation — one that predominantly relies on humans to do their jobs safely. Through the lessons of this course, I am better equipped to understand, support, and lead our team towards a goal of having a just culture and a deeply rooted psychological safety.”

“Guidance on how to form an effective team, particularly in short periods with unknown people and personalities. Others should do it as it breaks down — into understandable chunks — how to get people working together safely and effectively. These are skills that are not taught at any level within television production.”

““It's one of the most engaging sessions I have had during the PTQA course. What stands out is how much of it extends beyond work. The way of thinking around behaviour, context and decision-making just makes sense the more I reflect on it. Your personal experiences made the lecture very credible and enjoyable. It's a great example of the level I would like to work towards in the future.” ”

“Without any exaggeration, this is truly life-saving stuff. The course filled in a lot of the knowledge gaps for me — many of which I didn't know I didn't know. As a wonderful bonus, these concepts are not just helpful in their original domain. I was one of many students saying how excited they were to bring these ideas into their wider lives as well.”

“In the matter of two days our class went from being five strangers to a cohesive unit, based on our training. This course is invaluable for anyone who ever works as part of any team, regardless of their background.”

“The wildland fire service operates in an environment that requires leaders and their teams to be competent in every capability covered in this course. The operating environment inhibits learning. When it goes well, we can claim the success is because of our abilities, and when it goes badly, we are able to blame factors beyond our control. What we need to do is acknowledge we have fewer experienced leaders and team members, and lean in. Every capability this course enhances is essential to success.”

“Provided valuable insight into the individual and group qualities that contribute towards dysfunctional and high-performing teams. Also gave a structured approach which can be adapted to a wide range of situations to improve individual and team satisfaction, learning, decision-making, safety and efficiency.”

“Taking this course has been a transformative experience, providing me with valuable insights into my own behaviours, thought processes, and actions. By reflecting on myself from a higher level, I gained new perspectives that helped me identify recurring patterns in my interactions. This self-awareness has not only deepened my understanding of how I approach challenges, but has also made me more conscious of how I interact with others, both in my passion for diving and my career in IT.”
