Why High Performing Teams Start at the Top: The Leadership Truth Nobody Wants to Say Out Loud
Rebecca Veksler is a keynote speaker, fractional COO and CMO, and founder of SoL Cups, one of the top four reusable cup brands in the world. Through her consultancy RLV Projects, she has spent years working inside some of Australia's major corporate groups and high growth businesses, advising on leadership, culture and operational strategy. She speaks on leadership and high performing teams through Saxton Speakers Bureau.
I have sat inside some of Australia's most interesting organisations and watched the same thing happen over and over again.
A leadership team that cannot understand why their culture is broken. A founder who is genuinely confused about why their best people keep leaving. A people and culture team that is implementing initiative after initiative and wondering why nothing is sticking.
And in almost every single case, the answer is the same.
The problem starts at the top.
Not always with bad intentions. Not always with obvious behaviour. Sometimes with a founder who is so focused on growth that they have stopped paying attention to the humans around them. Sometimes with a leadership team that has promoted the wrong people into management roles and cannot bring themselves to admit it. Sometimes with a CEO whose nervous system is so dysregulated under pressure that every meeting they walk into becomes a pressure cooker.
High performing teams do not happen by accident. They are built deliberately, from the top down, by leaders who understand that culture is not a HR initiative. It is a leadership responsibility.
The Truth About High Performing Teams That Most Leadership Content Gets Wrong
There is an enormous amount of content in the world about high performing teams. Frameworks, models, assessments, workshops. Most of it focuses on the team itself: how to improve communication, how to build psychological safety, how to run better meetings.
And all of that matters. But it misses the most important variable.
You cannot build a high performing team with a low performing leader at the top of it. You cannot culture engineer your way out of toxic leadership. And you cannot retain your best people in an environment where the person setting the tone does not model the behaviour they are asking for.
This is the conversation that most leadership consultants are too polite to have. I am not.
In my years of fractional COO and CMO work inside major corporates and high growth businesses, I have seen the hidden killers of high performing teams. And they are almost never what organisations think they are.
The Hidden Killer: Managers Who Should Not Be Managing People
If toxic leadership at the top is the most obvious problem, the hidden killer sitting just below it is this: managers who should never have been put in charge of people.
This is one of the most common and most costly mistakes organisations make. A high performing individual contributor gets promoted into a management role because they are excellent at their job. But being excellent at a job and being excellent at leading people who do that job are completely different skill sets.
The result is a manager who is technically competent but relationally disastrous. Who micromanages because they do not trust anyone to do it as well as they can. Who cannot give feedback without it becoming personal. Who creates an environment of anxiety and second guessing that slowly hollows out the team underneath them.
These managers are rarely identified early, because their individual output looks fine. The damage they are doing is invisible in the metrics until the resignations start.
I have seen teams of genuinely talented, motivated people completely dismantled by a single manager who should not have been in that role. The cost, in lost talent, lost institutional knowledge and lost momentum, is staggering. And it is almost entirely preventable.
Systems Thinking as a Leadership Skill
Here is something I have come to believe strongly through my operational work: most leadership problems are systems problems.
Not in the sense that the system is to blame and the people are off the hook. But in the sense that the way an organisation is structured, the incentives it creates, the communication pathways it does or does not have, the roles it does or does not define clearly, shapes the behaviour of the people within it in ways that most leaders do not fully understand.
The question I always bring to a leadership challenge is not what is wrong with this person, but what is the system producing this outcome, and what would need to change for a different outcome to be possible.
This is systems thinking, and it is one of the most underrated leadership skills in the modern organisation. Particularly in the age of AI, where change is moving fast and the second and third order consequences of decisions are increasingly difficult to predict, the ability to zoom out, see the whole picture and understand how each part of the system affects the others is the difference between a leader who is reactive and one who is genuinely strategic.
What I Have Seen Inside Australia's High Growth Businesses
Through my fractional work, I have had the unusual privilege of sitting inside many different organisations at once, seeing patterns across industries, sectors and stages of growth that most leaders only ever see from inside one organisation at a time.
And the patterns are remarkably consistent.
The organisations with the highest performing teams almost always have leaders who are self aware, who can regulate their own emotions under pressure, who communicate with genuine transparency and who hold themselves to the same standards they hold their teams to.
The organisations with the most dysfunction almost always have leaders who are not those things. Who create environments of fear or uncertainty. Who avoid difficult conversations. Who promote based on loyalty rather than capability. Who mistake activity for output and busyness for performance.
The good news is that leadership is a skill. It can be developed. The leaders I have seen make the biggest transformations are the ones who are willing to look at themselves first, before they look at their teams.
What High Performing Teams Actually Have in Common
After years of working inside organisations at every stage and scale, here is what I consistently see in teams that genuinely perform.
Clarity. High performing teams know what they are trying to do, why it matters, and what their individual role is in achieving it. Ambiguity is the enemy of performance. The leader's job is to create clarity, not add to the fog.
Psychological safety with high standards. The research on this is unambiguous. Teams that feel safe to speak up, to disagree, to share bad news without fear of punishment, consistently outperform teams that do not. But psychological safety without high standards produces comfort, not performance. The best teams have both.
A no blame culture that still holds people accountable. There is a difference between blaming people for mistakes and holding people accountable for their impact. The best leaders I have seen can make that distinction clearly and consistently. They tie feedback to behaviour and impact, not to identity or character.
Communication that flows across departments, not just up and down. The most damaging communication failures I see in organisations are not between leaders and their direct reports. They are between departments that have stopped talking to each other. High performing organisations invest as much in horizontal communication as they do in vertical.
Leaders who do the work on themselves. Consistently, the teams that perform best are led by people who are in some form of ongoing development, whether that is coaching, peer learning, therapy, or simply the practice of genuine self reflection. You cannot lead people well if you are not willing to look at yourself honestly.
Practical Starting Points for Building a High Performing Team
If you are a leader reading this and recognising some of these patterns in your own organisation, here is where to start.
Look at yourself first. Before you assess your team, assess your own leadership honestly. What are you modelling? What are you avoiding? Where are your blind spots? This is not comfortable work, but it is the most important work.
Audit your management layer. Who is managing people in your organisation, and are they actually equipped to do it well? Technical competence is not enough. Look at the environments each manager is creating and take the results seriously.
Get obsessive about clarity. For every team and every role, make sure there is absolute clarity about what success looks like, what the priorities are and how individual work connects to the broader mission.
Invest in cross departmental communication. Create regular touchpoints between departments. Make it someone's explicit job to ensure alignment across teams. Do not assume it will happen organically.
Make it safe to tell you things you do not want to hear. The most important information in any organisation is the information that is not making it to the top. Build the conditions where people feel genuinely safe to bring it.
Frequently Asked Questions About Leadership and High Performing Teams
What makes a high performing team? High performing teams share several consistent characteristics: clarity of purpose and role, psychological safety combined with high standards, strong cross departmental communication, a no blame culture that still holds people accountable, and leaders who model the behaviour they expect. High performance is not accidental. It is the result of deliberate leadership choices.
Why do high performing teams fail? Most high performing team failures trace back to leadership. Either toxic or disengaged leadership at the top, managers who are not equipped to lead people, a lack of clarity about priorities and roles, or a communication breakdown between departments. Technical or strategic problems are rarely the root cause.
What is the hidden killer of high performing teams? In my experience, the most consistent and underestimated killer of high performing teams is managers who should never have been put in charge of people. Technically excellent individuals promoted into management roles without the relational skills to lead effectively create environments of anxiety, micromanagement and disengagement that quietly hollow out a team over time.
What is systems thinking in leadership? Systems thinking in leadership is the ability to see an organisation as a whole, to understand how each part of the system affects the others, and to identify the structural and cultural conditions that are producing current outcomes. Rather than asking what is wrong with this person, a systems thinker asks what is the system producing this outcome and what needs to change.
How does toxic leadership affect team performance? Toxic leadership creates environments of fear, uncertainty and psychological unsafety that consistently suppress performance. People in toxic environments spend significant cognitive energy managing their own safety rather than doing their best work. They stop sharing bad news, stop taking risks and start looking for the exit. The damage is often invisible in the metrics until the resignations begin.
