When you’re reviewing your leadership team’s performance, what metrics are on the table? Revenue. Margin. Pipeline. Retention. Possibly NPS or engagement scores. All important. All necessary.
But here’s what’s almost certainly not on that list: whether the people driving those desired KPIs results are actually going to be able to sustain doing so. Whether the way your organisation is designed is quietly depleting the very people you’re relying on.
And if that’s not on your radar, you have a performance risk sitting right in the middle of your business that you’re not measuring, managing, or mitigating. What could possibly go wrong?!
Why Your Best People Are Running on Empty
Here’s the thing. Burnout isn’t just about working long hours. It’s not solved by a yoga class or a fruit bowl in the kitchen — as well-intentioned as those things might be. Burnout is the result of people chronically overspending their cognitive energy. And the modern workplace is absolutely designed to accelerate that process.
Think about what your people are navigating right now:
- Global teams that require people to operate across multiple time zones, extending their working day in ways that erode recovery time.
- An “always on” culture where instant responses have been mistakenly conflated with high performance. Continuous partial attention — that state of being half-present across multiple things simultaneously — is one of the fastest ways to drain cognitive capacity and increase error rate. The neuroscience is clear on this, even if the culture hasn’t caught up.
- A calendar full of back-to-back video meetings, many of which could have been an email — or didn’t need to happen at all. People sit on calls they’re not genuinely present for, half-listening while simultaneously trying to get actual work done. This isn’t multitasking. It’s a guaranteed way to do two things badly while feeling exhausted by both.
- Restructures, mergers, and acquisitions that create layers of change fatigue on top of an already stretched workforce.
- The pressure to integrate AI thoughtfully — not just technically, but in a way that actually supports people rather than adding another cognitive load for them to manage.
- Multi-generational teams where people are naturally wired differently, communicate differently, and often don’t have a shared framework for navigating those differences.
- Increasingly polarised belief systems, amplified by social media, making everyday workplace communication more fraught than it needs to be.
- Life. People are bringing the weight of an uncertain world into the workplace, and that has a very real cost to their available energy.
- Organisational ambiguity — unclear decision-making processes, undefined communication norms, no shared framework for how people give feedback or disagree. These gaps burn through cognitive energy at a rate most leaders significantly underestimate.
This isn’t a list of excuses. It’s a list of real energy drains that are silently costing your organisation performance, quality, and talent retention. And most organisations are managing none of them systemically.
When I Led a Team, I Took the Flu Personally
When I was leading a distribution team in financial services, I used to take it as a personal failing if someone on my team came down with the flu.
That might sound dramatic, but the neuroscience backs it up. Catching the flu is very often a sign that someone’s stress response has been overactive for a sustained period — suppressing their immune system and leaving them vulnerable. If I was leading my team effectively, they should have been operating in the optimal stress zone for performance: enough pressure to drive results, not so much that their biology was working against them.
At Next Evolution Performance, we’ve been saying for years that managing energy for sustainability should be included in the KPIs for both leaders and individuals. Not as a wellness initiative. As a performance metric.
Because here’s the bottom line: no organisation achieves high performance results when the people producing said results are exhausted. If you have a team of burnt-out people, that’s a leadership problem. And in some cases, it’s also a structural problem with the organisation itself.
What Human Sustainability Actually Looks Like in Practice
So what does it mean to genuinely treat human sustainability as a performance metric? It means making systemic changes to how people work — not adding wellness programs on top of an already broken system.
Here’s what that looks like in practice:
Teach people how to structure their days using neuroscience. Most people plan their day as though they have a consistent level of energy from start to finish. They don’t. We have approximately four hours of peak cognitive energy per day. Everything else requires more time, more effort, and produces more errors. When people understand this and design their days accordingly, they do in four hours what previously took six — and they’re not depleted at the end of it.
Educate people on the neuroscience of stress and its direct impact on performance. Understanding the relationship between stress, the nervous system, and cognitive capacity isn’t a “nice to have.” It’s foundational to performing well consistently — and when people understand what’s actually happening in their brain under pressure, they make smarter decisions about how they manage themselves.
Eliminate at least 50% of internal meetings. Then make the remaining ones far more productive. Internal meetings are one of the most significant and underestimated energy drains in modern organisations. The volume and quality of meetings in most companies would not survive serious scrutiny.
Build a culture with explicit norms. How do people give and receive feedback? How do they disagree productively? Who makes which decisions, and how? Ambiguity in these areas is a constant, invisible drain on cognitive energy. When the culture is explicit, people spend less energy navigating uncertainty and more energy on the work that actually matters.
Invest in psychological capital. Hope, optimism, self-efficacy, and resilience aren’t soft skills — they are measurable, buildable capabilities that have a direct impact on performance and burnout. Research shows that teams with higher psychological capital can be up to 50% less burnt out than those without it. That is not a marginal improvement. That is a significant competitive advantage.
What This Looks Like When It Works
One of our clients — a financial services firm with a high-performing but consistently overstretched leadership team — came to us not because they were in crisis, but because their senior leaders kept burning out just as they were hitting their stride. They’d develop strong talent, the person would deliver for 18 months, and then they’d either leave or significantly underperform. The organisation had good intentions and wellbeing initiatives. But the system itself — the meeting culture, the “always on” expectations, the lack of clear decision-making processes — was working directly against those intentions.
When we worked with them to make systemic changes — restructuring how the leadership team worked, building explicit cultural norms, and upskilling leaders to manage their own energy and their teams’ — the shift showed up in retention, decision-making quality, and the team’s ability to sustain performance through a significant period of organisational change.
That’s what treating human sustainability as a performance metric looks like in practice.
Why This Can’t Wait
The pressures on your people are not going away — AI disruption, global complexity, change fatigue, and generational friction are all intensifying. The organisations that will outperform over the next decade won’t just have the best strategy. They’ll be the ones that figured out how to get the best out of their people consistently, without burning through them. The window to get ahead of this — rather than simply reacting to attrition and sick leave — is now. And it’s not as complicated to fix as it sounds, particularly with the flexibility that today’s ways of working afford.
The Metric Your Business Is Missing
I’ll leave you with a question. If you had to honestly assess your organisation right now — not how people say they feel in an annual engagement survey, but how the system is actually designed — would you say it is set up to protect sustainable performance over the long term?
Or is it set up to extract maximum output until people have nothing left to give?
Most organisations, even the well-intentioned ones, are closer to the second than the first. Not because their leaders don’t care. But because no one has built human sustainability into the performance system itself.
So what does it actually look like to include this in a performance management system? Let me make it practical.
At the individual level, once you have coached people in how to optimise their energy — which is the prerequisite — you can legitimately include sustainability in how performance is assessed. Are they structuring their days to protect peak cognitive hours? Taking genuine recovery between high-demand periods? Managing their stress response, or running hot and calling it dedication? These aren’t soft questions. They are directly correlated with the quality and consistency of output.
At the leader level, the metrics need to reflect whether the leader is actively protecting their team’s capacity — not just driving output. Some indicators worth building into leadership performance reviews: What is the sick leave and absenteeism rate in their team? What does attrition look like, and more importantly, are people leaving burnt out? How does the team score on psychological capital measures — hope, optimism, self-efficacy, resilience — which are quantifiable and directly predictive of burnout risk? Is the leader modelling sustainable working habits themselves, or are they the reason their team feels they need to be available at all hours?
At the organisational level, the data already exists in most businesses — it’s just not being interpreted through an energy lens. Sick leave, presenteeism, engagement trends, productivity, and error rates all tell a story about whether the organisation’s design is sustaining or depleting its people. The difference is measuring these as performance indicators — not just HR metrics — and holding leaders accountable for the results.
The critical point here is sequencing. You cannot hold people accountable for a metric they haven’t been given the tools to influence. This only works if you invest in genuinely upskilling your leaders and teams in how to work sustainably first. Once you’ve done that, measuring it is both fair and powerful.
And it doesn’t have to be complicated to start. One of the simplest and most effective measures is also the most overlooked: regularly asking people to rate their energy on a scale of 1–10. At Next Evolution Performance, we use 8 out of 10 as the benchmark. If someone is consistently rating at 8 or above, they have the cognitive capacity to perform at their best. If they’re consistently sitting at 5 or 6, they are technically showing up but operating well below their potential — and the quality of their thinking, decision-making, and output will reflect that, whether or not it’s visible yet.
Leaders can track this for their teams in weekly check-ins. Individuals can track it for themselves as part of their own performance habits. Over time, patterns emerge that are genuinely useful: which periods of the year are most depleting, which team structures or projects are consistently draining energy, and whether the interventions you’re making are actually moving the needle. It’s a leading indicator — it shows you where performance is heading before the results data catches up.
That’s the work we do at Next Evolution Performance. And it’s not a fruit bowl in the kitchen.
