She was the best relationship manager the branch had ever seen.
A consistent top performer, clients loved her, her numbers were untouchable. So when the branch manager role opened up at one of Nigeria’s leading commercial banks, the decision felt obvious. She had earned it.
Eighteen months later, the branch she had inherited was one of the lowest performing in the region.
Not because she lacked intelligence. Not because she lacked commitment. But because nobody had asked the more important question before handing her the role: had she ever actually been built to lead people?
This is one of the most common patterns in organisations across Nigeria and the broader African market. High performers are elevated into line management roles on the basis of individual excellence and then performance dips. This aligns with research, which indicates that approximately 60% of new managers fail within their first 24 months in the role, largely because they struggle to transition from “doing” the work to “leading” the people who do it.
The problem almost always comes back to the same thing. The understanding of what line managers are actually for, and what it truly takes to build them well.
The Environment That Has Made This Problem Harder to Ignore
Before examining what organisations are getting wrong, it is worth being precise about what has fundamentally changed. Line managers today are leading teams that may never share the same physical space, managing workforces that span dramatically different generational expectations about autonomy, purpose, and how leadership should feel.
They are operating inside organisations undergoing digital transformation, where systems, workflows, and ways of working are in constant flux. And increasingly, they are navigating environments where artificial intelligence is reshaping what coordination, analysis, and decision-making look like at the team level.
There is a structural change in what the line management role now requires. And most organisations have not updated how they build, assess, or develop their line managers to reflect it.
The Errors That Are Undermining Your Line Management Layer
These patterns appear consistently across industries.
Error 1: Treating Line Managers as an Administrative Function
The most foundational error is reducing the line management role to workflow management. What this misses is that modern organisations do not primarily struggle with order.
They struggle with alignment, speed, and adaptability.
When line management is built as an administrative function, managers become custodians of process rather than drivers of performance. Managers in many organisations spend up to 70% of their time on individual contributor work and administrative tasks, leaving very little room for team development or strategic alignment.
They ensure that systems run but they do not ensure that the organisation moves forward, or that the people within it do. The downstream consequences are predictable: productivity plateaus, engagement erodes, and operational performance becomes reactive rather than intentional.
Order is not the problem. Momentum is.
Error 2: Measuring Motion Instead of Progress
Consider what a typical week looks like for most line managers. A full calendar, back-to-back meetings, steady volume of communications, coordination, and status updates. It creates the convincing appearance of effective management.
Only 20% of middle managers globally strongly agree that their organisations are helping them succeed in the role. Yet these same managers are often rated as highly active.
Busy and effective are not the same. An organisation that cannot tell them apart will struggle to build capable line managers.
Error 3: Relying on Authority in a Workforce That Has Already Moved Past It
The relationship manager who got promoted tried to lead the way she had been led. A results-first culture built on pressure and proximity. Her team disengaged within months.
What worked on her did not work on everyone. Today’s workforce operates differently. Employees expect autonomy rather than constant direction, expertise is distributed rather than hierarchical, and influence is earned through credibility, not conferred through a new job title.
When organisations design line management roles around formal power, engagement suffers, collaboration becomes forced, and leadership quality varies wildly based on individual personality rather than system design.
Error 4: Digitising the Work Without Redesigning the Role
Organisations have transformed how work is done. They have not transformed how line management is defined. Automation, analytics, and AI have absorbed many of the traditional coordination and reporting functions that once justified the line manager’s existence.
The real value of line managers in a digital environment now lies in areas that technology cannot replicate: contextual judgment, cross-functional alignment, human engagement, and the kind of behavioural change that determines whether transformation actually lands or quietly stalls.
This shift is supported by research, which identifies “leadership and social influence” and “emotional intelligence” as two of the top skills rising in importance as automation takes over routine management tasks.
The tragedy?
Those ignored factors are the ones that determine whether someone thrives or fails as a leader.
The Shifts Organisations Must Make in How They Build Line Managers
From administration to momentum — designing the line management role around alignment, speed, and adaptability rather than process compliance, so that managers drive performance rather than simply maintain order.
From oversight to enablement — measuring line managers by the capability and commitment they build in their teams, not by how closely they monitor the work being done around them.
From authority to influence — developing line managers who earn credibility through coaching and consistency, rather than relying on the formal power a title confers.
From digitising work to redesigning the role — updating what line management means in an AI-enabled environment, so that managers are invested in the areas technology cannot replicate: judgment, alignment, and human development.
When Line Management Works, You Can See It
Effective line management looks like
- Clarity where there is complexity.
- Accountability that does not depend on pressure.
- Coaching that happens consistently, not only when something goes wrong.
- Decisions made at the right level, by the right people, without unnecessary escalation.
It looks like a team that does not fall apart when the manager steps away. That is the standard. And it is achievable
Final Thought: Line Managers Are Built, Not Simply Promoted
Something in this article likely resonated. Perhaps it was the relationship manager who was handed a role she had never been prepared for. Perhaps it was the errors, familiar, uncomfortable, closer to home than most organisations would care to admit.
Building effective line managers is a strategic commitment to the belief that performance, at scale, is always the result of people who were deliberately developed to bring out the best in others.
The organisations that understand this do not just have better managers.
They have everything better.
