Rethinking Talent: Star Performers, Power Laws and the Future of Performance Management

Why do some individuals and firms consistently outperform others? And what if the way most organisations measure performance is fundamentally flawed?

In this session of the Dean’s Distinguished Speaker Series, Professor Herman Aguinis, Avram Tucker Distinguished Scholar and Professor of Management at the George Washington University School of Business, challenged one of management’s most enduring assumptions: that performance follows a bell curve. Drawing on more than a decade of large-scale research across nearly one million individuals, from athletes and artists to CEOs and academics, he argued instead for a power-law distribution, in which a small minority of “star performers” contribute a disproportionate share of value.

The lecture was opened by Associate Professor Marilyn Ang Uy, Head of the Division of Strategy, International Business and Entrepreneurship, who framed talent decisions as strategic rather than administrative in today’s environment of tighter labour markets, rising expectations of fairness, and the growing use of AI in work systems. The session was moderated by NBS alumna Ms Jovin Ong, Executive Director of Human Resources in the real estate sector, who brought a practitioner’s perspective to the discussion.

The following is an edited transcript of the Q&A segment:

Ms Ong: How do you define a star performer today, beyond just output? What attributes matter?

Prof Aguinis: A simple way to describe a star is that they are better than the others, but that is a relative definition. It is not about an absolute threshold. Star performers are defined by the difference between their contribution and that of their peers.

Importantly, stars are not merely high individual producers. They help their teams and organisations succeed. Think about Jack Welch. Not only did he create extraordinary shareholder value at GE, he also produced more Fortune 500 CEOs than any other CEO. That is star performance: creating value not just for oneself but elevating everyone around you.

Ms Ong: Are star performers always stars?

Prof Aguinis: No. Stars are defined by what they do, not who they are. That distinction is critical.

When organisations define stars based on identity such as gender, background or personality type, bias creeps in. When we define stars by output and contribution, we can reduce those biases.

The challenge is measurement. Many organisations do not measure performance well. If you cannot define performance clearly and align it with strategy, you cannot reliably identify stars. Often, what appears to be a performance problem is in fact a leadership or strategy clarity problem.

Ms Ong: If only a small minority are stars, how do we motivate average performers without demoralising them?

Prof Aguinis: There is nothing wrong with being an average performer. By definition, not everyone can or wants to be a star. Some people prefer to work 40 to 45 hours a week; others choose 70. That is an individual choice.

What matters is equal opportunity, not equal output. Provide everyone with access to development, training and performance-based rewards. Not everyone will pursue them, and that is perfectly acceptable.

Even the greatest goal scorers depend on passes from teammates. Stars need strong and steady contributors around them.

Ms Ong: Performance management is often seen as broken. Where does the breakdown occur?

Prof Aguinis: In many firms, performance management becomes a compliance exercise that managers rush through at year-end.

That is not performance management; it is an administrative burden.

Performance management should be a strategic tool. It should help managers identify who needs support, who may be at risk of leaving, and where to allocate resources. If done properly, it can shape organisational culture because you reward what you truly value.

The breakdown often begins when HR systems are disconnected from strategy and from the realities of line managers. If performance metrics are not aligned with where the organisation is heading, the entire system falters.

Ms Ong: How do we avoid creating a purely transactional, high-pressure culture while still differentiating performance?

Prof Aguinis: Performance systems must be consistent with organisational culture.

An investment bank and a not-for-profit organisation cannot use the same model. You must decide whether to emphasise individual or team results, outputs or behaviours, competition or collaboration.

This alignment requires deep contextual understanding, which AI alone cannot determine. That is where leadership and HR expertise remain indispensable.

Audience Member: Is there an optimal ratio of stars to average employees?

Prof Aguinis: We do not yet have a universal ratio, and it likely varies by industry and resource availability.

Stars are expensive. They create enormous value but require investment. Too many stars without sufficient resources can create tension. True stars, however, are defined by how they elevate the enterprise, not by ego.

Ms Ong: How do you handle managers who suppress stars because they feel threatened?

Prof Aguinis: That is a leadership system failure.

Mediocre managers often feel threatened by high performers. If you allow them to remain and be promoted, they will drive stars away.

One solution is structural accountability. At Dell, for example, no manager is promoted unless their direct reports rate them highly. This reduces the incentive to manage upwards while neglecting teams.

If you want stars to shine, you must prevent poor leadership from obstructing them.

Ms Ong: How do you identify future stars, especially late bloomers who have not yet produced standout results?

Prof Aguinis: Research shows that performance is driven by two primary factors: ability and motivation.

For junior employees, ability may not yet be fully visible. So we look for indicators of potential such as cognitive abilities, learning orientation and especially motivation. Do they actively seek growth? Do they invest in developing themselves?

Motivation often signals future star potential.

Ms Ong: What is one thing organisations should stop doing if they truly care about performance?

Prof Aguinis: Stop promoting mediocre managers.

Poor leadership causes enormous damage. It drives stars away, weakens culture and erodes long-term competitiveness.

If you want sustainable performance, address leadership quality first.

Ms Ong: How often should ‘stay interviews’ be conducted?

Prof Aguinis: Managing performance is not an annual event. It is daily work.

A stay interview does not need to be formal. It can be as simple as noticing exceptional performance in real time, describing it specifically and recognising it immediately.

Effective managers manage every day, not once a year.

In closing, Professor Aguinis emphasised that talent must be viewed as an integrated system, from recruitment and selection to development, performance management and compensation. When one component fails, the entire system weakens.

Echoing the evening’s central theme, Dean Jun Yang noted parallels with research in finance on “super managers” and scalable talent. As organisations become more knowledge-intensive and technological advances reduce constraints, marginal differences in talent can generate outsized impact.

The message was clear. If organisations continue to design systems around the bell curve, they risk constraining their very best performers. If they remove ceilings, invest strategically in people and align performance with purpose, star performers can become a powerful engine of sustained competitive advantage.
