Using Coaching as a Leadership Development Tool: How Managers Develop Better Leaders Through Effective Coaching

Leadership development has moved decisively away from the annual workshop and the one-off training seminar. I have watched this shift happen from the inside, first as an HR practitioner building manager curricula and later as an executive coach. The data backs up what the field already knows anecdotally. The 70-20-10 framework popularized by the Center for Creative Leadership has held up for decades because it is true. Roughly 70% of how leaders actually develop comes from on-the-job experience, another 20% comes from relationships and feedback, and only about 10% comes from formal training. Coaching lives squarely in that 70-20 zone, which is exactly why it has become the highest-leverage development tool available to a manager.

Google’s own internal research is worth citing here because it is one of the few large-scale, data-driven studies on what makes managers effective. Project Oxygen, the multi-year analysis Google ran on its own management population, found that being a good coach was the single most important behavior separating high-performing managers from the rest. It ranked above technical expertise, above strategic vision, and above almost everything else measured. That finding reshaped how Google trains managers, and it has shaped how I advise clients too.

Traditional classroom-style leadership training also has a well-documented retention problem. Learning and development research going back to Hermann Ebbinghaus’s forgetting curve, reinforced by more recent corporate L&D studies, consistently shows that most classroom content is forgotten within weeks unless it is reinforced through repeated, applied practice. A two-day offsite does not build a habit. A five-minute coaching conversation after a missed deadline, repeated weekly for a year, does.

Coaching changes what a manager fundamentally is. Instead of a senior problem-solver who hands down answers, the manager becomes a developer of people. They build judgment, ownership, and confidence in others rather than simply directing their next move. When it works, feedback lands as constructive and forward-looking rather than as personal criticism, because the entire point of the exercise is capability, not compliance.

What Does Coaching Mean in Leadership Development?

It is worth separating organizational coaching from the executive coaching most people picture. That picture is usually a paid outside consultant working one-on-one with a C-suite client over months. That is a real and valuable practice. The International Coaching Federation’s 2023 Global Coaching Study estimated tens of thousands of active professional coaches worldwide. However, that is not what we are talking about here.

Inside a company, coaching is something a manager does as part of the job, not a scheduled deliverable from an outside expert. It is an intentional, recurring practice woven into daily and weekly interactions. Its aim is building a direct report’s skills, confidence, judgment, and self-awareness over time.

The distinction that matters most is this. Coaching is not delegation, and it is not issuing instructions. A manager who tells someone exactly what to do is directing. A manager who asks the right question at the right moment is coaching.

Here is what that looks like in practice. Say a team member hits a blocked project milestone. Maybe a vendor has not delivered, or a cross-functional dependency has stalled. The instinct for most managers, especially technically strong ones, is to jump in and fix it. A coaching manager resists that pull. Instead, they ask what the employee has already tried, what options remain on the table, and what they would recommend if the decision were entirely theirs. The manager may still weigh in because coaching is not about withholding expertise. But the employee leaves the conversation owning the solution, not just executing someone else’s.

Why Organizations Use Coaching to Develop Better Leaders

Companies do not invest in coaching because it is trendy. They invest in it because it solves structural problems that formal training never touches.

Developing Managers Into People Leaders

The Peter Principle problem is real and well documented. Organizations routinely promote their best individual contributors into management, assuming technical mastery translates into people leadership. It rarely does automatically. A star engineer or top sales rep promoted to team lead often struggles with the exact skills coaching builds. These include delivering hard feedback, motivating a team with mixed skill levels, navigating a tough performance conversation, or developing a struggling junior employee. Structured coaching, whether from that manager’s own boss or through a formal coaching program, closes this gap far faster than a leadership seminar does. It happens in the exact moment the skill is actually needed.

Building a Leadership Pipeline From Within

Internal mobility is one of the clearest levers a company has against the cost and risk of external executive hiring. External hires have a well-known higher failure rate and take longer to reach full productivity than internal promotions. This pattern has been documented repeatedly in workforce research over the past two decades. Coaching surfaces potential early. A manager who regularly coaches their team knows, long before a formal talent review, who is ready for a stretch assignment and who needs another six months of runway. That intelligence is what turns a generic succession plan into a real, defensible pipeline.

Creating a Culture of Continuous Improvement

Gallup’s long-running State of the Global Workplace research has repeatedly found that manager quality is the single largest driver of team engagement. Gallup’s figure puts the manager’s influence on engagement variance at roughly 70%. A coaching culture is what converts that influence into something positive. Regular, low-stakes conversations about performance make feedback normal rather than an annual ambush. Employees stop waiting to be told what is wrong and start actively asking for input. That is the single clearest sign a coaching culture has taken root.

How Managers Actually Use Coaching as a Leadership Development Tool

Good coaching is not improvisational. It follows a repeatable structure, even when the conversation itself feels natural and unscripted.

Start With Development-Focused Conversations

Coaching starts with genuinely understanding what an employee wants out of their career, what is currently getting in their way, and where their real strengths and gaps sit. It is not the sanitized version that shows up in a performance review. It is the honest version that only surfaces in a trusting one-on-one.

The best managers open these conversations with questions that invite reflection rather than defense. What skill do you most want to sharpen this quarter? What is the biggest thing slowing you down right now? What have you already tried, and what did you learn from it?

Use Questions Instead of Immediate Solutions

This is the hardest behavioral shift for experienced managers, especially those promoted for their own problem-solving speed. A directive manager says Here is what you should do. A coaching manager asks What are you seeing, and which option do you think gets us there fastest.

Marshall Goldsmith, one of the most cited executive coaches in the field, built an entire body of work around a related idea he calls adding too much value. This is the habit successful people have of jumping in with their own answer before someone else finishes forming theirs. Coaching requires managers to consciously resist that impulse, even when they are certain they already know the right call.

Provide Feedback That Encourages Growth

Feedback should be delivered positively and constructively, not because harsh feedback is unkind, but because it is ineffective. Neuroscience-informed leadership research, including work popularized by Daniel Goleman on emotional intelligence in leadership, consistently shows that feedback perceived as a personal attack triggers a defensive, threat-based response. This response shuts down learning rather than enabling it.

The most reliable structure I have seen hold up across industries follows a clear sequence. Name what is genuinely working first. Be specific about what needs to change and why it matters. Work through possible solutions together rather than prescribing one. Close by agreeing on a concrete next step both people will actually follow up on.

Coaching Techniques Every Manager Should Master

A handful of core techniques separate managers who coach well from those who just talk about coaching.

Active Listening: This means listening to understand, not listening to respond. There is no interrupting and no mentally drafting your reply while the other person is still talking. The goal is to catch what is underneath the words, such as the frustration someone will not say out loud, the resource gap they have not flagged, or the confidence issue masquerading as a scheduling complaint.
Powerful Questioning: Open-ended questions build a muscle that closed yes or no questions never will. Strong prompts include what did you learn from how that played out, what would you do differently next time, and what support would actually make the difference here.
Goal Setting and Accountability: Coaching conversations that never connect back to a concrete goal tend to evaporate. Pair every developmental conversation with a specific milestone, a realistic timeline, and a scheduled check-in. Otherwise, even a great conversation becomes a one-time event instead of a growth trajectory.

Coaching Models Leaders Can Apply in Workplace Conversations

Managers new to coaching benefit from a repeatable framework rather than winging it every time.

GROW Coaching Model

Developed in the UK in the 1980s by Sir John Whitmore along with colleagues including Graham Alexander and Alan Fine, GROW remains the most widely taught coaching model in corporate leadership programs worldwide. It structures a conversation around four distinct stages:

Goal: What does the person want to achieve?
Reality: What is actually happening right now?
Options: What alternatives exist?
Way Forward: What specific action comes next?

Its staying power comes from its simplicity. Any manager can run a GROW conversation in fifteen minutes without formal coaching certification.

Situational Coaching Approach

Not every employee needs the same coaching style, and treating them identically is one of the more common mistakes new managers make. This idea traces back to the situational leadership model developed by Paul Hersey and Ken Blanchard in the late 1960s. A new hire typically needs more direction and hands-on guidance. An experienced specialist does better with autonomy and a sounding board. A high performer being groomed for a bigger role thrives when challenged with ambiguity rather than handed a checklist.

Coaching vs Mentoring vs Managing: Understanding the Difference

These three roles get blurred constantly, and the confusion creates real friction on teams.

Managing: Managing is about the work in front of you right now. It covers task execution, near-term results, resource allocation, and direct oversight of output.
Mentoring: Mentoring draws on someone’s own career path and hard-won experience to help another person navigate theirs. Think career advice from someone who has already walked the road, rather than a structured developmental process tied to current performance.
Coaching: Coaching is neither of those. It is the practice of helping someone find their own answer and build durable capability, even when the coach already knows what they would do in that situation.

The best leaders I have worked with move fluidly between all three roles depending on what the moment calls for, sometimes even in the same conversation.

Why Some Coaching Conversations Fail to Create Real Development

Coaching done badly is often worse than not coaching at all because it teaches employees that the process is theater.

A manager who turns every coaching conversation into a monologue has just repackaged directing with a different label.
Saving all feedback for the annual review means small issues calcify into big ones before anyone addresses them.
Asking a question and then visibly not listening to the answer, such as checking a phone or moving straight to your own point, tells an employee the question was never sincere.
Applying the exact same coaching style to a brand-new hire and a fifteen-year veteran ignores situational reality.
Agreeing on next steps in a coaching conversation and then never following up is the fastest way to convince a team that development is just corporate jargon.

How Organizations Can Build a Strong Coaching Culture

None of this scales without deliberate support from the top. Companies serious about a coaching culture typically train managers in a shared framework like GROW rather than leaving coaching style to chance. They build coaching expectations directly into how managers themselves are evaluated. They encourage feedback to flow in more than one direction, noting that Deloitte’s Global Human Capital Trends research has repeatedly flagged continuous, multi-directional feedback as a top workforce priority. They also use regular pulse surveys rather than annual engagement surveys alone to catch problems while they are still small.

Managers also need protected time. Coaching gets crowded out by operational fires unless leadership explicitly makes room for it. This is often the single biggest reason coaching initiatives stall after a promising launch.

How to Know Whether Coaching Is Improving Leadership Capability

The clearest signal is not a training completion rate. It is what shows up in the business. Track engagement survey trends over time rather than a single snapshot. Watch whether performance conversations start surfacing real issues instead of surface-level status updates. Look at internal promotion rates versus external hires for leadership roles, and pay attention to upward feedback on managers specifically, not just team output.

Rising confidence and initiative among employees, such as people making calls they would previously have escalated, is one of the most reliable early indicators that coaching is actually working. This often shows up well before it registers in a formal metric.

When Using Coaching as a Leadership Development Tool, How Should Feedback Be Delivered?

Feedback should be delivered positively and constructively, full stop. This is not a soft-skills nicety. It is the mechanism that determines whether feedback actually changes behavior.

Coaching exists to build capability and confidence, not to enforce compliance through fear. Harsh, purely critical feedback triggers defensiveness almost immediately. A defensive brain is not in a state to learn or adapt because it is in a state to protect itself. Constructive feedback, by contrast, makes the needed change clear without torching the person’s motivation to make it.

Take a project manager who misses a critical client deadline. A coaching-style conversation starts by acknowledging the team pushed hard under real constraints. It then works through where the process actually broke down, exploring whether it was a scoping issue, a dependency nobody flagged early enough, or an unrealistic timeline. It finishes by building a revised approach together for the next deliverable. That is a fundamentally different conversation than telling someone this cannot happen again, and it is the one that actually prevents a repeat.

Why Coaching Has Become an Essential Leadership Skill

No leader, no matter how talented, scales their impact through their own individual output alone. The leaders who build lasting organizations are the ones who develop other people capable of solving problems and delivering results without them in the room.

That is the entire case for coaching. It is not a soft addition to real management. It is what turns a manager into a leader whose impact outlasts their own individual contribution.

Frequently Asked Questions

What is coaching as a leadership development tool?

It is a developmental approach where managers guide employees through reflection and targeted questioning to build skills, decision-making ability, and self-awareness, instead of simply issuing instructions.

How does coaching help develop better leaders?

It builds self-reliance, sharpens problem-solving, strengthens emotional intelligence, and prepares high-potential employees to take on broader responsibility. This matches the behavior Google’s Project Oxygen research identified as the top differentiator of its best managers.

Should coaching feedback be positive or negative?

Feedback should always be delivered positively and constructively. Purely critical feedback triggers defensiveness and shuts down the learning it is meant to enable.

What coaching skills should managers develop?

Active listening, powerful open-ended questioning, structured goal setting, and specific, behavior-based feedback.

What is the difference between coaching and mentoring in leadership?

Coaching helps people find their own solutions and build lasting capability. Mentoring draws on a mentor’s own career experience to offer direct advice and perspective.

How can organizations create a coaching culture?

By training managers in a shared framework like GROW, building coaching into how managers themselves are evaluated, encouraging continuous multi-directional feedback, and protecting the time managers need to actually do it.
