The best managers shape careers mainly by matching people to the roles where they fit best. That is the finding of new research reported in Harvard Business Review in October 2025. The study uses 20 years of data on 200,000 employees and 30,000 managers in nearly 100 countries.

The research identifies good managers as those who are promoted early. These managers raised employees' productivity and wages, and the benefits lasted even after the manager or the employee moved on.

This article explains the study, what matching means in practice, and how organisations and individuals can use the findings. A note on dates: this research is older than most of the 2026 material we cover, since it appeared in October 2025. The summary is based on a search extract, so it keeps to the facts the extract gave.

What the best managers research found

The study looks at a very large sample. It covers 20 years of data, 200,000 employees, 30,000 managers and nearly 100 countries. That scale makes it unusual. Most management research uses much smaller samples, from a single firm or country.

The main finding is that the best managers add value by matching people to the roles where they fit best. In other words, their main contribution is not motivation speeches or detailed supervision. It is putting the right person in the right job.

The study identifies good managers using a particular marker, namely those who were promoted early. It then compares the results of their teams with those of other managers. Employees working for the best managers, as identified by early promotion, showed higher productivity and higher wages.

It is worth noting that the extract does not give the full method. The use of early promotion as a marker of quality is a choice by the researchers, and it has limits. Early promotion may also reflect politics or luck. Still, the scale of the data and the consistent results make the finding worth attention.

Why matching people to roles matters so much

Matching sounds simple, but it is powerful. People differ in skills, interests and working styles. Jobs differ in what they demand. When a person is in a role that suits them, they tend to perform better and enjoy the work more.

Think of a team with an analytical thinker, a creative generalist and a natural organiser. A manager who puts the analyst on a data task, the generalist on a design problem and the organiser on project coordination will probably get better results than one who assigns tasks at random.

Matching also applies at the career level. One habit of the best managers is noticing when an employee would thrive in another team. A manager who notices this, and helps them move, is making a good match even if it costs the manager a team member. The research suggests that this kind of move creates lasting value.

The skill involved is judgement about people. It requires attention, curiosity and honesty about strengths and gaps. It also requires a willingness to look beyond your own team.

Organisations can support matching by making internal moves easy, sharing information about opportunities and rewarding managers who develop talent for the wider company.

What promoted early tells us about the best managers

The researchers use early promotion as a sign of a good manager. This choice is both useful and debatable.

It is useful because promotion is measurable across many firms and countries. It allows the study to include thousands of managers without having to judge each one personally. The idea is that people promoted early are likely to have strong skills, and that organisations see these skills.

It is debatable because promotion can reflect other things. Some people are promoted because of connections, visibility or being in the right place. Others who are excellent managers may be overlooked.

The extract does not say how the researchers handled these concerns. Readers should therefore treat the label best managers as shorthand for managers who were promoted early, and not as a perfect measure of quality.

Still, the link between early promotion and better results for employees is interesting. It suggests that organisations can sometimes spot talent, and that the people they promote early can make a difference to the careers of those they manage.

For anyone who wants to be promoted, the study hints that the skill of matching people to roles may be worth developing.

Higher productivity and wages for employees

The study finds that good managers raised employees' productivity and wages. These are two of the most concrete outcomes in the labour market.

Productivity gains show that people did more or better work. Wage gains show that the labour market rewarded them. Together they suggest that the manager's impact was real and valuable, not just a matter of mood.

How do the gains come about? Matching is the main route according to the study. When people are placed in roles that suit them, they learn faster, make fewer errors and contribute more. Over time, they build skills that command higher pay.

The finding fits with Gallup's work, which shows that managers account for 70% of the variance in team engagement. Engagement and productivity are linked, and a manager who engages people and places them well can lift both.

For employees, the message is encouraging. A good manager can change your career trajectory. If you have a manager who helps you find the right role, value that relationship. If you do not, look for mentors and sponsors who can fill the gap.

For employers, it is a case for investing in management quality, since the returns appear in both results and pay.

Why the benefits lasted after moves

Perhaps the most intriguing result is that the benefits lasted after the manager or the employee moved on. The effect was not limited to the time that the person worked for the manager.

That points to something durable. If a manager helps you find the right role and builds your skills, you carry those gains with you. Your better skills, track record and confidence remain even when your manager changes.

It also suggests that the manager's influence works partly through learning. People who work for strong managers may pick up habits and judgement that stay with them. They may also build networks and reputations that help later.

For organisations, durable benefits make the case for good management stronger. A manager is not just a supervisor of current results. A manager is a builder of future capability.

For individuals, it means that choosing your manager matters. When you consider a job, ask about the manager's track record in developing people. A good manager may be worth more to your career than a slightly higher salary.

Keep in mind that the extract does not give the size of the lasting effect. Read the original for the figures.

How organisations can use the best managers findings

Organisations can turn the findings into practice.

First, select managers carefully. Look beyond technical skill, and assess people skills, judgement and interest in developing others. Gallup's estimate that organisations pick the wrong manager 82% of the time shows how common mistakes are.

Second, reward matching. Make internal mobility easy, and recognise managers who help people move to roles where they shine. Avoid managers hoarding talent.

Third, share information. Make sure managers know about opportunities across the firm, and that employees can see them too.

Fourth, develop managers in assessing strengths and fit. Training in conversations about talent, feedback and career planning helps.

Fifth, measure outcomes. Track the careers of people who move, and look for patterns.

Select managers on people skills as well as technical skill.
Reward managers who develop and move talent.
Make internal vacancies visible.
Train managers in strengths and fit conversations.

These steps can help organisations learn from the best managers, and turn the study's insight into concrete benefits.

What employees can do to be well matched

Employees need not wait for a manager to find the right fit. You can help the matching process.

Know yourself. Notice which tasks give you energy, which you do well and which you avoid. Ask colleagues and managers for feedback on your strengths.
Share what you learn. Tell your manager what you enjoy and what you want to learn. Many managers do not know unless asked.
Look for stretch opportunities. Volunteer for projects that match your strengths, and use them to test your fit.
Explore internal moves. Talk to people in other teams, and learn about their work. If a role looks like a good fit, express interest.
Build a record. Keep notes of your results so that you can show your value.

If your manager is not helping, look for sponsors elsewhere. A senior person who knows your work can open doors.

The study suggests that being matched well can shape your whole career. It is worth taking an active part.

Everyday habits of managers who match people well

The research does not list habits, so what follows is a practical translation of its main idea, not a finding of the study. If the best managers add value by matching people to roles, what might they do day to day?

They ask questions. They want to know what each person enjoys, what they find hard and where they would like to grow. They ask often, since answers change.
They observe. They notice who lights up during certain tasks, who gets stuck and who helps others. They treat these observations as data about fit.
They experiment. They give people small, safe chances to try new tasks, and watch what happens. A short project can reveal more than a long interview.
They are open to moves. They talk about career paths, introduce people to other teams and support transfers, even when it costs them a strong performer.
They give honest feedback. They say what a person does well and where a different role might suit them better.
They keep learning. They read about talent, ask for feedback on their own management and compare notes with peers.

Any manager can adopt these habits. They take time but little money, and the study suggests that they can pay off in higher productivity and pay for the people you lead.

Why South African organisations can use the best managers lessons

The study spans nearly 100 countries, so its message is not limited to one market. South African organisations can learn from it in several ways.

In a country with high unemployment, every job matters, and good matching helps people keep and grow their jobs. A person in the wrong role may struggle and be dismissed, while the same person in the right role may thrive.

Public and private employers alike can build systems that make matching easier, such as internal job boards, rotations and mentoring. Learnerships and graduate programmes can include rotations through several areas, so that young workers and their managers can discover where they fit.

South African managers also lead diverse teams, with different languages, backgrounds and expectations. Good matching starts with listening, and that is especially important across cultural differences.

Finally, the finding that benefits last after a move is encouraging for a mobile workforce. Investing in people pays off even if they later leave. Organisations that develop talent, and are known for it, tend to attract strong applicants. The best managers build both the careers of their people and the reputation of their employers.

How to read the HBR study with care

This is a research summary, so a few cautions apply.

The extract is short. It does not give the effect sizes, the method for linking managers to outcomes or the countries with the strongest results.
The label good manager is based on early promotion, which may be an imperfect measure. If promotion practices differ across firms and countries, the label may mean different things.
Correlation is not always cause. Employees who work for early-promoted managers may differ in other ways, such as being placed in stronger teams. The authors likely tried to account for this, but readers should look at the method.
The study is older than most 2026 material. It appeared in October 2025, so it predates many of the changes of 2026, such as the rise in AI use at work.
The article is in Harvard Business Review, a respected publication, but still a summary. For full detail, look for the underlying paper.

Final thoughts

The best managers shape careers mainly by matching people to the roles where they fit best. Using 20 years of data on 200,000 employees and 30,000 managers in nearly 100 countries, the research finds that managers promoted early raised employees' productivity and wages, with benefits that lasted after a move.

For organisations, the lesson from the best managers is to select managers for people skills, to reward matching and to make internal moves easy. For employees, it is to know your strengths, share them and look for good managers and sponsors.

Remember that the study dates from October 2025 and that the summary rests on a search extract. Read the original for the full evidence.
