The Cause Of The Chernobyl Disaster

In 1986, the Chernobyl power plant suffered a major disaster that directly killed 31 people and is estimated to have indirectly killed over 4000. Whilst the plant itself possessed an inherently unsafe design, the culture in Russia at the time did not encourage the raising of concerns or speaking up about mistakes. A fear of authority and the need to please political masters resulted in a fear-driven culture. During a simulated power shutdown, operators who were not fully equipped to deal with the situation made a series of protocol mistakes which resulted in a steam explosion, followed by a nuclear explosion. The cause of the disaster was in large part because operators did not speak up about their concerns.

The Definition of Psychological Safety

Thirteen years later, Dr Amy Edmondson was studying clinical teams and the number of mistakes that different teams made. During her research she was surprised to find that the teams with a higher number of good outcomes actually made more mistakes than teams with fewer good outcomes. It was a surprising result, but after further investigation, Dr Edmondson discovered that in fact those teams with better outcomes were admitting more mistakes, whilst the teams with fewer good outcomes were more likely to hide theirs. As a result, Dr Edmondson formulated the concept of psychological safety, namely: the belief that one will not be punished or humiliated for speaking up with ideas, questions, concerns, or mistakes. She believed that psychological safety was a key factor in team performance. Dr. Edmondson continues to lead the field in expounding the importance of psychological safety in all fields of work and life, and literally wrote the book on psychological safety.

Psychological Safety Underpins Team Performance

Think about the best team you’ve been a member of. It could be a sports team, a business team, or some other group of people with a shared goal. Being a member of that team probably felt good, it may have even been energising and inspiring. Whilst the members of that team may well have been experts in their field, it’s likely that being a member of that team felt good because that team felt safe to be themselves. They, and you, likely felt free to admit mistakes, ask for help, and even challenge ideas from other team members without fear of humiliation or embarrassment.

Now think about one of the worst teams you’ve been a member of. Perhaps you felt that you had to put on a metaphorical “mask”, and be a different version of yourself in order to fit in. You may not have been able to admit mistakes, or ask for help, in case members of the team saw it as a weakness and used it against you. Chances are, you didn’t feel very “safe” in this team.

Think of these two teams when thinking about levels of psychological safety. Psychological safety isn’t a binary “on or off” factor, it’s a sliding scale. Teams (and members of those teams) possess it to varying degrees. The best team you’ve been on probably possessed a lot, whilst the worst probably did not possess much at all. This pack will support you to increase the psychological safety experienced by your team right now.

The Difference Between Leadership and Management

management and leadership

It’s important to recognise the difference between these two practices. The indubitable Grace Hopper once stated that “You manage things, you lead people.” What she meant is that management consists of all the processes, tools, and controls that need to exist in order for people to work effectively, whilst leadership is far larger in scope and consists of, for example, setting direction, making strategic decisions, supporting and motivating people, and elevating people in order to reach their highest potential.

In practice, this means that neither management nor leadership can be neglected.

In order for people to perform well and possess psychological safety, they need to operate in environments where safety, costs, tools and processes are managed effectively. A team cannot deliver if they do not know how, or indeed what to deliver. Management is therefore part of leadership, and contributes to the “structure and clarity” that Google’s Project Aristotle defined as the third most important factor in high performing teams. Incidentally, guess what the most important factor they identified was? Yes, exactly. Psychological safety.

Google’s Project Aristotle was a turning point for psychological safety. It was enough proof for what we all intrinsically know – that feeling safe to be yourself as part of a team, where you’re able to contribute your ideas, admit mistakes, challenge others respectably, and try without fear of failure, is one of the most powerful aspects of human performance.

The Four Stages of Psychological Safety

Timothy R Clarke in his book “The Four Stages Of Psychological Safety” described four stages of psychological safety that teams can move through, progressing from stage 1 to stage 4. These are:

(1) Inclusion Safety – members feel safe to belong to the team

(2) Learner Safety – members are able to learn through asking questions

(3) Contributor Safety – members feel safe to contribute their own ideas

(4) Challenger Safety – members can question others’ ideas or suggest significant changes

Another useful model for team development is Tuckman’s Model of Team Development, where teams “Form”, “Storm”, “Norm”, and finally, “Perform”. It is only in psychologically safe teams that true performance will be reached, since this stage requires the ability for team members to admit and learn from mistakes, and to contribute and challenge ideas. Reaching this stage, as a leader of a team, is your goal.

Measuring Psychological Safety

It’s really important, and fortunately, really easy to measure psychological safety. You can do this in your team or across an entire organisation, the Psychological Safety Action Pack is a toolkit that contains thorough and detailed resources on measurement, specific actions to take according to the scores you record, and exercises, tools, and workshops to run with your teams to continuously build psychological safety and performance in your workplace.

The Three Fundamentals of Psychological Safety

There are three core leadership behaviours which support psychological safety in teams. These may seem simple, but in practice they extend to every single leadership behaviour and every single aspect of communication. Those three core behaviours (thanks to Amy Edmondson for codifying these) are: 

  • Frame work as a learning problem, not an execution problem Everything is an experiment. The outcome of work should not exclusively be the output; it must also be learning how to do it better next time.
  • Acknowledge your own fallibility. By admitting when you make a mistake or don’t know the answer, you allow (indeed, encourage) others to do the same.
  • Model curiosity and asking questions. Stay curious, ask other people what they think, and ask them to contribute. By asking questions and asking for help, you’re creating a space and a need for people to speak up, which is essential for psychological safety and for high performing teams.

Dr Amy Edmondson elucidates these core principles in The Fearless Organization.

building and maintaining psychological safety for your team

Whether you work for a private company, non-profit organisation, a government agency or a sports team, building psychological safety and working through the psychological safety action pack will return real results:

The Benefits of Psychological Safety:

  1. Increased likelihood of successful innovation, resulting in quicker time-to-market.
  2. An increased ability to learn from mistakes, resulting in fewer problems or outages, higher quality, and improved governance and controls.
  3. Increased reporting of concerns and security issues, resulting in decreased risk of security, health and safety or non-compliance incidents.
  4. Increased employee engagement, resulting in lower churn rates and decreased costs related to recruitment and absenteeism.
  5. Improved reputation resulting in an increased ability to recruit the best people.
  6. Increased profitability as a result of all of the above.

Fundamentally, building psychological safety is not only the right thing to do for members of your teams, but it’s the right thing to do for your business or your organisation.
