Mentor, coach or supervise

Dear captains, if we observe carefully across organisations, a consistent pattern emerges.

One of the biggest drains on managerial time is not the workload itself, but how that time is allocated.

Many leaders spend a disproportionate amount of time dealing with low performers. This often comes from good intentions. They want to help. They want to nurture. They want to be seen as supportive leaders.

But we must ask: is this truly in line with the organisation’s success?

The truth is, most managers do not fail because they lack effort. They fail because they apply the wrong approach, at the wrong time, to the wrong person.

Leadership is not just about intention. It is about making the right judgment calls for the right individual at the right time.

Spending excessive time trying to change an uninterested low performer brings limited returns. Redirect that same time to someone ready to learn and grow, and the results can be exponential.

As captains, this is not something we can leave to chance. We must guide how leadership time and attention are used across our organisations.

We must ensure that our leaders mentor stallions to run faster, coach eagles to fly higher, and appropriately supervise those who are not yet ready.

We begin by seeing our people clearly. Sound judgment must be based on capacity, actual performance, and future potential.

Bell curve

In most organisations, performance follows a familiar pattern. While not exact, a basic bell curve helps us see our people more clearly.

At the top, about 10% consistently deliver and often exceed expectations. These are our A and B+ performers. They are rare, highly capable, and often drive disproportionate results.

At the bottom, another 10% struggle to meet minimum standards. These are our E performers. They face both capability and attitude challenges and often require close supervision.

The real challenge lies in the 80% in between. This group is too large and too varied to be treated as one. To lead effectively, we must break this middle into three segments.

First, about 15% sit close to the top. These are our B and C+ individuals. They are strong contributors, not far from moving up, and represent a critical pool of future talent.

Next, the largest group, about 50%, forms the steady core. These are our C performers. They ensure stability, continuity, and reliability. They perform as expected. While not all aspire to move up, they remain essential.

The role of leadership here is to sustain performance and, where possible, lift it incrementally. This is where leaders must learn to engage and negotiate effectively. After all, C performers are already giving us exactly what we asked for. They are performing as expected.

This is where strong negotiation skills become important.

The challenge is to negotiate for a little more – not dramatically more, just an additional 5% to 10%. If even a portion of this group moves towards C+, the impact is significant.

Because this is the largest segment of the workforce, small gains across a large group create meaningful organisational improvement.

Finally, about 15% sit just above the lower end. These are our C- and D performers. They are inconsistent. At times, they may perform well, but they lack discipline and consistency. Left unattended, they risk declining further.

When we see this clearly, several truths emerge.

A and B+ performers are difficult to find and even harder to retain. Yet they remain critical to performance and innovation.

The B and C+ group is often overlooked. In reality, this is our most important talent pipeline.

With the right development, they can grow into future high performers and are more likely to stay and grow with the organisation.

C performers are the backbone of execution. The C- and D group requires structure and discipline to stabilise performance. And our lowest performers require firm supervision.

Once we see our people through this lens, we must accept a simple truth: not everyone should be led the same way.

Three hats model

Before deciding when to mentor, coach, or supervise, we must be clear on what each role requires.

When we wear the hat of a mentor, our role is to guide and develop the individual beyond immediate tasks.

Mentoring is relationship-focused and long-term. It is about shaping the person, not just improving performance. It happens through periodic, meaningful engagement and often begins with the talent.

The mentor helps the individual see what they may not yet see.

When we wear the hat of a coach, our role shifts to improving performance. Coaching is task-focused and job-specific.

It requires the most time and attention from leaders. It involves regular interaction to build skills, close gaps, and move individuals to the next level.

When we wear the hat of a supervisor, our role is to ensure that work meets required standards. Supervision is directive and structured. It is immediate and frequent but should take the least amount of time. The focus is on discipline, clarity, and ensuring minimum standards are met quickly and consistently.

With this understanding, we can now be clear on when to apply each approach.

For our A and B+ performers, the primary role is to mentor.

These individuals do not need instruction; they need perspective, challenge, and growth beyond their current role.

At the bottom 10%, the role is to supervise. The focus is on discipline, structure, and minimum standards. Supervision should consist of frequent, short, structured check-ins, but it should not consume excessive time.

The objective is to bring them up to the required level as quickly as possible. The goal is to shape them up or shift them out. The real work of leadership lies in the 80% in between.

For the 15% just below the top, our B and C+ group, a hybrid approach is required.

Leaders must both coach and mentor. Coaching builds capability, while mentoring provides perspective. This is our most important pipeline into future high performers and talent.

At the centre, the 50% C performers, coaching is critical.

This is where leaders must invest most of their time, or delegate the responsibility to capable seniors. Improving this group, even marginally, creates significant organisational impact.

For the 15% just above the lower end, our C- and D group, another hybrid is required. Leaders must combine coaching and supervision. Coaching builds skill, while supervision ensures discipline and consistency.

This is where leadership becomes demanding. It is not about choosing one style, but about knowing when to shift and when to combine.

Dear captains, this is why it is critical that our leaders know when to mentor, when to coach, and when to supervise.

The ability to apply the right approach to the right person at the right time is what separates an average manager from an effective leader-manager.
