Sarah was the best systems engineer on her team. Her code was elegant, her designs were bulletproof, and she could debug problems that stumped everyone else. So when her manager left, promoting Sarah seemed like the obvious choice. Six months later, she was drowning, her team was frustrated, and two of her best people had started looking for other jobs.
This scenario plays out thousands of times every year in organizations across every industry. We take our highest performers—people who have demonstrated excellence in their craft—and promote them into roles that require an entirely different set of skills. Then we act surprised when things don’t go well.
The problem isn’t Sarah. The problem is a fundamental misunderstanding about what leadership actually requires.
Technical excellence and leadership excellence require different—and sometimes opposing—mindsets. The skills that made someone promotable are not the skills that will make them successful as a manager.
When you’ve spent years developing deep technical expertise, your identity becomes intertwined with that knowledge. You’re the person who knows the answer. Your value to the organization has always been measured by what you personally can produce.
Now imagine being told that your job is no longer to have the answers, but to help others find them. Your value isn’t what you produce, but what your team produces. Every instinct you’ve developed over years of technical work now actively works against you.
New technical managers typically operate under three assumptions that seem logical but are actually destructive:
- “I should have all the answers” – Your credibility as an engineer came from having the answers. But when you position yourself as the person with all the answers, you create a bottleneck.
2. “If I want it done right, I need to do it myself” – You can work 60 hours a week and produce 60 hours of output. Or you can spend 20 hours developing five team members who each become 20% more effective.
3. “My technical skills are what make me valuable” – Your value as a manager comes from making others successful. The best managers actively seek to hire people smarter than themselves.
Becoming an effective manager requires a fundamental shift in how you see yourself and your role. This isn’t just learning new skills—it’s changing your identity.
The solution isn’t to stop promoting technical experts into management. The solution is to prepare them for the transition with structured development, safe spaces to practice, and metrics that measure team success rather than individual contribution.
Sarah wasn’t a bad manager. She was an unprepared manager. With the right support, most struggling new managers can turn things around. The skills of leadership can be learned.
