Building a team is a complex system that changes with every interaction; it can't be solved with fixed instructions. Unlike a complicated but predictable task like building a Ferrari, leading a team requires constant experimentation, sensing, and responding to an ever-evolving dynamic.

Technically proficient professionals often falter when promoted to management because they try to apply logical, predictable models to human interactions. This approach fails because people are not systems that can be modeled, leading to frustration and ineffectiveness.

The instinct for a hands-on leader is to fix every problem themselves, which doesn't scale. Growing requires developing the intuition to distinguish between critical issues (glass balls) and less important ones (rubber balls) that can temporarily fail, freeing up time for higher-leverage tasks.

Effective engineering leadership is like farming: growth isn't achieved by demanding it from the plants. Leaders should obsess over inputs—clear goals, sound strategy, team structure, and operational rigor—to create the conditions for great engineering to happen naturally.

When an engineer proposes a flawed idea, directly saying "no" can cause resentment. A more effective leadership technique is to ask guiding questions about potential impacts. This allows the individual to discover the flaws themselves, fostering independent problem-solving and preserving their autonomy and confidence.

The most common mistake for new leaders is reverting to their individual contributor mindset, feeling the need to provide answers directly. True leadership success comes from shifting to a facilitator role, enabling the team to find solutions, which provides more long-term value and scales their impact.

The "treat others as you want to be treated" mantra fails in leadership because individuals have different motivations and work styles. Effective leaders adapt their approach, recognizing that their preferred hands-off style might not work for someone who needs more direct guidance.

A key lesson from Allspring CEO Kate Burke's experience is that leaders must be chameleons. Instead of expecting employees to mirror their style, leaders should adapt their management approach to unlock the unique potential of each individual, fostering a more diverse and effective team.

Instead of feeling frustrated by what team members lack, effective leaders focus on finding roles where their people's innate "encodings" can shine. This shifts the work from trying to change people to aligning their responsibilities with their natural capacities, leading to awe and gratitude rather than frustration.
