The Manager Who Was Great Last Year and Is Struggling This Year
The performance data has been declining for two quarters. The team that was delivering reliably under this manager’s leadership last year is now missing deadlines, raising more escalations, and producing more internal friction than the organisational structure accounts for. On paper, nothing significant has changed. Same manager. Same team. Roughly similar resource allocation.
What changed is the context.
The company is bigger. The problems are harder. The decisions the manager is being asked to make are more complex, involving more stakeholders, more ambiguity, and higher stakes than the environment they were trained in. And the manager, who is a genuinely good person with genuine capability, has not yet developed the specific skills that this new context requires.
This is one of the most common and most consistently misdiagnosed performance problems in Nigerian organisations. The manager who is struggling is frequently treated as though something has gone wrong with them: a change in attitude, a lapse in motivation, a personal problem affecting their work. The real explanation is simpler and more structural. The context has changed faster than the capability development that would allow this person to succeed in it.
What Changes When the Context Changes
Management capability is not a fixed property. It is contextually embedded. The same person who is excellent at managing a team of six in a high-growth, resource-rich environment may be genuinely struggling with a team of fourteen in a cost-constraint environment that requires a fundamentally different leadership approach.
A manager in a small, fast-moving team needs to be a strong individual contributor who can also direct work, maintain team cohesion, and communicate upward effectively. The premium is on technical judgment and personal credibility. Team management in this context is largely relationship-based.
A manager in a growing team during a period of constraint needs to be a systems thinker who can delegate without losing quality, develop capability in team members rather than compensating for it personally, manage performance explicitly rather than through cultural osmosis, and maintain team cohesion under conditions of workload pressure and resource scarcity. These are different skills. The manager who has never needed to develop them has not developed them.
Research from Gallup consistently shows that managers account for 70% of the variance in team engagement. This means the performance problem you are seeing in the team is, in most cases, a management problem before it is a team problem. Understanding which dimension of management capability has failed to keep pace with the context is the diagnosis that determines the intervention.
The Three Capability Gaps That Surface in Changed Contexts
1. From doing to enabling. The manager who was promoted because they were the best individual contributor often continues to operate as an individual contributor: doing the complex work themselves rather than building the capability of their team to do it. This is the most common capability gap in Nigerian tech and fintech companies, where technical excellence is the primary promotion criterion and management development is rarely a structured part of the post-promotion journey.
The symptom is a manager whose team appears to be performing but whose team members are not growing and whose output collapses when the manager is unavailable. As the team grows, the mathematics of one person doing becomes the mathematics of a bottleneck.
2. From managing individuals to managing a team. Managing three people and managing twelve are categorically different leadership challenges. At three, the manager can hold all the relationships, all the context, and all the performance awareness personally. At twelve, they need structured systems: regular one-on-ones with consistent agendas, team communication mechanisms that do not depend on the manager being in every conversation, explicit performance tracking that does not rely on the manager’s memory.
The manager who has not made this transition is usually the one whose direct reports have inconsistent experiences of being managed: some feel well-supported, some feel ignored, and the allocation is related to proximity and relationship rather than role importance.
3. From managing in abundance to managing in constraint. The manager who learned to lead during a growth period, when resources were relatively available and timelines were negotiable, often has no calibrated toolkit for leading during a period of cost pressure, slower growth, and team members absorbing more work than their role specification anticipated.
In this context, morale maintenance requires active and explicit effort rather than relying on ambient momentum. Prioritisation decisions need to be made and communicated, because the team cannot do everything and the manager who does not make trade-offs explicit leaves the team to discover them through failure.
The Diagnostic Conversation That Comes Before Any Intervention
The mistake most Nigerian organisations make when a previously strong manager starts struggling is to treat the performance gap as a motivation or attitude problem rather than a capability problem. This leads to conversations that focus on effort and commitment rather than the specific skills the manager needs to develop.
The more useful conversation starts with curiosity rather than assessment. What has changed in the manager’s responsibilities, team size, or environmental context over the past year? Where specifically is the gap appearing? What support has the manager received since their context changed?
For many Nigerian managers, the honest answer to the last question is: none. They were promoted, congratulated, and left to figure out the new role with the same toolkit that worked in the previous one.
Research consistently shows that 83% of managers have no formal training in people management. In Nigerian companies, where management development is rarely a structured programme and is more commonly assumed to happen through observation and experience, this percentage is likely higher. The manager who is struggling is usually a manager who has never been taught the specific skills their current role requires. The performance gap that appears six or twelve months after a promotion is not evidence that the promotion was wrong. It is evidence that the development investment was missing.
What the Intervention Looks Like
A manager who is underperforming because the context has changed requires a different intervention from a manager who is underperforming because they lack fundamental capability. The former needs specific skill development in the areas where the capability gap is greatest. The latter needs a more fundamental reassessment of role fit.
For the context-driven capability gap, the intervention is specific and time-bounded: identify the two or three specific management behaviours that would most improve team performance, design a structured development plan around those behaviours, and create accountability through regular check-ins with a more senior leader or an external coach.
The Nigerian organisation that makes this investment, rather than tolerating the performance gap in silence or moving to a performance management process designed for a different problem, retains a manager who has already proven their capability in a different context, develops the institutional capability that benefits the entire organisation, and sends a signal to the broader team that the company’s response to struggle is development rather than replacement.
The Structural Investment That Prevents the Problem
The most efficient version of this work happens before the performance gap appears. Companies that invest in structured management development, teaching newly promoted managers explicitly what changes at each stage of scale, what new skills are required, and how to develop them, produce managers who navigate context changes more smoothly than those who are left to discover the new requirements through experience.
This investment does not require a sophisticated learning and development programme. It requires the decision that management capability is a strategic priority rather than an assumed consequence of promotion.
