Unlocking high performance in teams and individuals

The journey to unlocking that performance starts here...

Human in the System has extensive training and coaching experience across civil and military aviation, intensive care units in healthcare, offshore oil and gas sector, executive levels within the corporate sector and high risk expedition teams, all to develop their latent abilities to become highly reflective and high performing teams with excellent communication skills.

To achieve this, Human in the System uses a combination of tools.

Firstly, GemaSim which uses specific and validated behavioural marker schemes for non-techincal skills development and HR assessment schemes. Secondly, the Process Communication Model, as used by NASA for nearly 20 years as part of their astronaut selection process, and now succesfully used by GM Finance, the Royal Australian College of Surgeons, and Wolverhampton NHS trust to name but a few. Both tools are linked at the top of this page.

Following an identification process, we use a combination of tool application, training, coaching and mentoring interventions to get what you want and need to improve your company's performance. 

Improving individual's skills. Developing high performing teams.

A team is only as strong as its weakest member.

Decision Making

Ultimately we want to make great decisions (or in some cases, decisions which are just good enough!) But we are biased in so many ways into making poor decisions. Human in the System uses theory, research and practice into decision making and cognitive biases from wide range of domains to show how and why decisions are made and how to make more effective ones.

Situational Awareness

This isn't just an aviation or military construct, it is at the core of our decision making. What is happening now. What does it mean to now. What does it mean in one hour, one day, one week, one month from now. There is a need to create a future model and constantly check it, and readjust our models of the world. If we don't errors happen.
Effective situational awareness leads to better decision making.


How often do you hear "I told him, but they didn't understand" or "He just winds me up the wrong way, I never listen to him"? Communications isn't just transmitting, it is receiving on the same channel and sending a response back. The majority of poor decisions and poor performance results are down to poor or miscommunication.
Effective communications improves team cooperation, leadership, situational awareness and ultimately effective decisions.


Is your team performing how you want it to be? Is morale high? Are decisions effective? Are targets met? Are targets even set?! Do you have toxic team members?
Every team goes through a recognised cycle of development, some progress faster than others. Effective teamwork improves communication, which in turn improves personal and team situational awareness, leading to more effective decisions being made.

Leadership / Followership

Great leaders are not born, they are developed. We can image great leadership, but not so easy to define a path to get there! What do you believe is missing in your organisation? What challenges do you think you will face in getting there? However, leaders aren't the only members of teams. We often talk about effective leadership and great teamwork, but what about those in the team other than the leader? How do they develop as effective supporting members? Their skills in supporting, challenging and developing the leader are as important as the leader when it comes to business outcomes. Effective leadership & followership improves communications and situational awareness, and reduces the negative impacts of stress & fatigue.

Stress & Fatigue

We often hear about Stress as being a negative concept, but stress is something we all need to function efficiently and effectively. The difficulty is knowing the limits and where Eustress (good) turns to Distress (bad). If we can recognise the subtle signs of stress in ourselves and others, we can improve communications, improve decision making, and act as a more coherent and co-operative team. Fatigue can significantly impact on many cognitive and non-technical skills, leading to reduced performance, safety and ultimately business outcomes.

The interdependence of Non-Technical Skills...

Non-technical skills are at the core of improved performance in a number of high risk, dynamic environments. These include aviation, healthcare, nuclear power, oil and gas and high threat bomb disposal. Using experience from these domains can improve your business or operation.

Ultimately we want to undertake effective Decision Making, but these decisions are informed and influenced by Situational Awareness and the cognitive biases we are all susceptible to. These can be reduced if we have effective two-way Communication, which is achieved by understanding the barriers and enablers to effective communications. Effective Teamwork, Leadership & Followership all improve communications and situational awareness. However, all of these can be impacted (positive and negatively) by Stress and Fatigue.

Can you afford not to know more about how Non-Technical Skills can improve your team and its outputs?

What Clients Think About Us

“Truly two of the most productive days I have had in regards to personal and professional development. The best part about the training is Gareth provides students with the tools to take what has been discussed in the course and implement it in our own courses and dive teams. Implementing the debriefing structure we learned in our Human Factors course proved invaluable as everyone in the team felt comfortable providing both critical and positive feedback for everyone (including the instructors) in the team. The goal shifted from the typical “do the skills well to pass the course” to “do the skills well to better support the team”, and it was a lot of fun to watch.”

~ Jon Kieren, Training Director, TDI/SDI/ERDI

“Thank you very much for running the day in such a way as to give freedom of expression and allow personalities to come through so well in such a short time. Insightful seems to have been the operative word. I found the day very interesting. It was surprisingly hard work and emotionally tiring - which surprised me but probably shouldn't have.”

~ Jack Parry-Jones, Consultant, ABUHB ICU Team

“We all like to think we are team players who can stay calm under pressure, but GemaSim really does highlight some painful truths about how we really interact with others and perform under pressure. Personality traits are laid bare forcing you to assess your own strengths and weaknesses - it really is a humbling but very enlightening experience. ”

~ Jason Brown, Owner BARDOCreative

“Fantastic opportunity to reflect on ones own practices, team and leadership skills, it will enhance team dynamics and effectiveness”

~ David Hepburn, Consultant, ABUHB ICU Team

“How to teach an instructor to influence their students in a positive way is always difficult. An understanding of these human factors is a very powerful tool that will be useful to any instructor candidate. I will be incorporating some of the ideas in my instructor development work. Gareth's training has given me tools that I will use to help my students understand how to communicate, lead and follow. These tools are a more-concrete approach to the problem, rather than the pragmatic ad-hoc approach I currently use.”
