Summary
First Leadership Role: Promoting your best engineer without guidance creates struggling leaders and frustrated teams. Technical excellence does not equal leadership skill. The unguided transition is costly: poor leadership drives up turnover, with replacements costing up to 200 percent of salary. Stop creating “accidental managers”. Secure the transition with a mentor from day one to teach the missing tools and build a capable leader without burning out a top expert.
You promote your strongest technical expert. And you lose both: the expert, and the leader he was never allowed to become.
This post is written for supervisors and HR leaders who decide on promotions and should know the arithmetic behind them. For the department head who makes his best engineer a team lead and wonders why the team suddenly stalls. For the HR manager who senses that a promotion without guidance is more expensive than any training. And for anyone who suspects that the first leadership role is not a step up but a change of profession.
Why technical excellence is not leadership
An outstanding engineer masters his craft because he has learned and practiced it over years. Leadership is a different craft, with its own tools, its own mistakes, and its own learning curve. Whoever promotes the best expert and assumes technical excellence will transfer to leadership on its own confuses two entirely different professions. This confusion is the most expensive and most common promotion decision I know, and it is avoidable.
What I learned about the rise in India
Why I still take courses at almost 50
My name is Andy Balbus. I am almost 50 and have been in leadership for over 20 years, and still I take at least one course on LinkedIn Learning or comparable platforms today. One would think I had seen and learned everything in that time, yet the opposite is true. From exactly these courses I still pull new ideas, new perspectives, and sometimes genuine new knowledge. If a person with this experience keeps learning constantly, how is a freshly promoted expert supposed to lead with no guidance at all?
Who becomes a team lead in India
During my time in India I strongly observed a pattern that I have confirmed through contacts at other firms. Very often the person promoted to team lead is the one with ten or more years of experience and proven technical expertise. The most experienced specialist is made a manager because he is the best at the craft, not because he ever learned leadership. This is not an Indian phenomenon alone, but there it stood out with particular clarity.
Why the title matters for the family
In India many people want this step deliberately, and the reasons reach far beyond the professional.
A higher title is something you show your family, it counts for admission to schools and kindergartens, and it opens doors that would otherwise stay closed to a family. Whoever needs the rise for his children and his standing will accept it, whether or not he is prepared for the new role. To ignore this human reality would be the wrong path; to understand it is the first step toward a better solution.
From expert to people leader without tools
What happens next is almost preordained. An experienced engineer with deep technical knowledge becomes what India so aptly calls a “people leader”, and in this role he lacks everything, because he never learned anything for it. This very often leads to enormous friction in the team, to attrition, and to performance problems. The person has not changed, only his task has, and for this new task nobody gave him the tools.
What a guide from day one changes
This is where my thought begins. What if these people, who need the jump for their families, had a mentor and coach at their side from the first day, company-funded and for a full year? I know from experience what that does. This guide costs money at first, and not little, yet he teaches the new leader the methods that lead to low attrition, high team performance, and real stability. In the end the company saves a multiple of the initial investment, because a single specialist who quits over poor leadership costs 150 to 200 percent of an annual salary to replace.
The first leadership role is not a medal for good work but a new profession. Whoever promotes the best expert and leaves him alone loses, in the end, two people in one.

What the numbers say about the unguided promotion
82 percent with no leadership training at all
The expert paradox is no exception, it is the norm. The Chartered Management Institute found that 82 percent of all new managers take on their first leadership role without any formal leadership training. These so-called accidental managers, the ones who stumbled into leadership, are promoted for their technical performance and then left alone with responsibility for people. They are expected to lead without ever having learned how, and the result is usually carried by the team beneath them, not by the organization that promoted them unprepared.
The promoted expert and the missing delegation skill
How large the gap really is shows up in the 2025 Global Leadership Forecast by the consultancy DDI, based on over 10,000 leaders across 50 countries.
Only 19 percent of rising leaders, it found, have the delegation skill needed to truly operate as a manager rather than as a highly paid individual expert. At the same time, 71 percent of leaders report significantly higher stress since taking on their current role. The promoted expert therefore keeps doing what he can, namely the technical task, because he lacks the tools for everything else, and suffers most in the process himself.
Why the unguided rise becomes a boomerang
The damage does not stay with the team lead, it spreads across the whole team. Gartner’s analysts show that the direct reports of a struggling new leader perform 15 percent worse on average and are 20 percent likelier to leave or to disengage. And exactly here the business case closes: a single specialist who quits over poor leadership costs 150 to 200 percent of an annual salary to replace. Against that sum a one-year company-funded mentor is not an expense but an insurance, whose return ICF and PwC analyses put at seven times the investment on average.
Three Honest Questions Before You Read On
Who did you last promote because he was the best at the craft, and what did you give him for the leadership?
Do you know what a single specialist costs you when he quits under an overwhelmed new leader?
And from when do you guide a new team lead, from the first day or only from the first visible problem?
If you hesitate on one of these questions, the next section is for you.
Guiding the transition: the BYG path in three steps
1. Understand the promotion as a change of profession
Step one is a question of stance. Treat the promotion not as a reward for good technical work but as entry into a new profession with its own learning curve. Make clear to the new leader and to yourself that technical excellence and leadership skill are two different things. How deep this change runs is shown in the post on the path from expert to leader, and why control does particular harm in this phase is described in the post on micromanagement, which is the most common trap for exactly the promoted expert.
2. Guidance from day one, not from the first problem
Step two decides between success and failure. Do not deploy the guidance when the first problem becomes visible, but from the first day of the new role. A mentor and coach teaches exactly the tools that never came up in the degree and the technical career: open-ended questions, active listening, and the uncompromising delegation that research shows almost all new leaders lack. Part of this is creating a climate where the team objects openly, as the post on psychological safety describes. The structured frame for this is provided by engineering leadership coaching and, for the technically shaped leader, by team lead mentoring.
3. Run the business case and secure the investment
Step three convinces the people who release the budget. Set the cost of the mentor against the sum a single departing specialist devours, and the arithmetic tips at once. Clear, measurable development goals from the SMART method and the GROW method make progress visible, and the priorities of the new leader you sort with the Eisenhower prioritization. How such investments pay off in real starting situations is shown in the case studies.

Voices from the Field
Why these two voices on a page about the first leadership role? Dhaval Patel, as a software engineer at Brose India, was one of the people I guided in their development, and his words show what matters in the transition: the right questions and genuine engagement in the guidance. Atharva Sasane, in turn, describes from the view of a young talent how good guidance not only transfers knowledge but lastingly shapes the way one thinks and works, exactly what a first leadership role needs.
Andy is a great coach. He shares his valuable experiences to give examples to explain topics in detail, and asks the right questions to explore deeper in the topic. Overall a good learning experience, and I hope to have a long collaboration with Andy.

FAQ: Straight Answers to Skeptical Questions
Q1: Why does my best engineer of all people struggle as a leader?
Because technical excellence and leadership skill are two different professions. Your best engineer grew strong by solving problems himself, yet as a leader he has to enable others to solve problems, and that is the opposite. Without guidance he falls back on what he can, namely the technical task, and neglects the leadership for which he lacks the tools. The transition is therefore not a talent problem but a preparation problem.
Q2: What exactly is meant by a guided first leadership role?
A guided first leadership role means the new leader has a mentor and coach at their side from the first day, ideally for about a year. This guide teaches the leadership tools, gives backing in difficult situations, and prevents harmful patterns from setting in. More terms around leadership and development are explained in the glossary.
Q3: Is a company-funded mentor for a year not too expensive?
This question turns the arithmetic around. The mentor costs money, that is true, yet the alternative costs more: a single specialist who quits over an overwhelmed leader devours 150 to 200 percent of an annual salary to replace. Add that struggling new leaders lower their team’s performance by 15 percent according to Gartner, and the investment in a guide is the cheaper option, not the more expensive one.
Q4: Why is a two-day leadership seminar not enough?
Because leadership is not a knowledge problem but a behavior problem. A seminar transfers information, yet the new leader stands alone again the following Monday facing the same situations. Behavior changes through guidance over time, through reflection on real cases, and through feedback in the moment, not through two days of theory. That is exactly the difference a mentor makes against a course.
Q5: Does the expert paradox apply only to India?
No, it is universal, in India it just stands out with particular clarity. Everywhere the best at the craft gets promoted, and everywhere he lacks the leadership craft without guidance. In India the family and social pressure is added, the need for the title for schools, kindergartens, and open doors, which accelerates the rise further. The pattern itself I know from every country I have worked in.
Q6: Should I then rather not promote the best expert?
Not necessarily, but you should treat the promotion as what it is: the start of a new profession. Some experts want to lead and flourish with guidance, others unfold their greatest value in a technical career without people responsibility. What matters is offering both paths and never pushing anyone into leadership unasked and unguided just because he is the best at the craft.
Q7: How do I recognize that a new team lead is starting to struggle?
By rising attrition, falling team performance, and the team lead fleeing back into the technical task. When someone who is supposed to lead suddenly programs or designs again while the team waits without direction, that is a clear signal. Frequent conflicts and a team lead who wants to control everything are also early warning signs, as the post on micromanagement describes. Rules worked out together give the new team lead early footing, as the post on team charter rules shows.
Q8: Who should provide the guidance, an internal or an external mentor?
Both have their place, yet an external mentor brings two advantages. He has no agenda of his own inside the company, and he can openly address what would be delicate internally. He also brings the experience of many similar transitions, instead of knowing only the one company culture. For the technically shaped leader, team lead mentoring is tailored to exactly this.
Q9: How long until the investment pays off?
Often faster than one thinks, because the most expensive damage arises early. Attrition and team climate are decided in the very first months, and a guide prevents exactly the mistakes in this phase that can hardly be corrected later. The real return shows over the year, when the struggling expert becomes a leader who holds and develops his team. ICF and PwC analyses put the return on coaching at seven times the investment on average.
Q10: How does such guidance help across cultures?
Across cultures guidance is especially valuable, because leadership is read differently in every culture. A mentor with intercultural experience helps the new leader find their own style without ignoring cultural expectations. How that works in practice is shown by intercultural mentoring, and how Andy guided the build-up of entire teams by executive sparring Slovakia.
Q11: How does BYG concretely help with the first leadership role?
The core is engineering leadership coaching, complemented by expert-to-leader mentoring for exactly this transition. For the acute relief of an overwhelmed team there is Accelerate Now, and how such engagements work in real starting situations is shown in the case studies.
The next step into guided leadership
If this post describes your next promotion, start where the transition is decided: with engineering leadership coaching, which guides the first leadership role, or with expert-to-leader mentoring. The mindset behind it is described in the BYG core principles, anyone looking for the full range of leadership development will find it in the coaching hub, and anyone who leads through expertise before the title arrives in leading without authority.
