Data's role is to reveal reality and identify problems or opportunities (the "what" and "where"). It cannot prescribe the solution. The creative, inventive process of design is still required to determine "how" to solve the problem effectively.
Self-aware managers recognize that their strengths and weaknesses are two sides of the same coin. For example, being deeply thoughtful (a strength) often means not being quick on your feet in meetings (a weakness). Acknowledging this link is key to personal growth.
In an era of accelerating change, a manager's role is to be like a willow tree. They must provide a sturdy, stable vision for the team while remaining highly flexible in how they adapt to storms and changing conditions. This combination builds team resilience.
Sundial founder Julie Zhu intentionally avoids hiring product managers. This constraint forces engineers to take full ownership of the product definition and user value, preventing them from delegating critical product thinking and developing a stronger sense of customer empathy.
Firing someone feels adversarial until you reframe it as a win-win. The employee wants to be successful and valued; if your team isn't the right place for that, helping them move on is a service to their career, not a disservice. This mindset changes the entire dynamic.
The skills of setting clear goals, understanding resource (model) strengths, and defining processes are the same for managing people and AI agents. Being a great manager makes you a great AI user, as both require clarifying outcomes and marshalling resources to achieve them.
Instead of trying to find the perfect words, preface difficult feedback by stating your own nervousness. Saying, "I'm nervous to share this because I value our relationship," humanizes the interaction, disarms defensiveness, and makes the other person more receptive to the message.
Julie Zhu observes that many of the fastest-growing companies grow so quickly they don't have time to build robust data logging and observability. They succeed on "good instincts and good vibes," only investing heavily in data infrastructure after growth eventually stalls.
Managers cannot just be soldiers executing orders. If you don't truly believe in a strategy, you cannot effectively inspire your team. You must engage leadership to find an angle you can genuinely support or decompose the idea into testable hypotheses you can commit to.
