What Exactly Are a Product Manager’s Core Capabilities?

1. Taste > All Skills

The author emphasizes that "taste" is the foundation of every product skill. It develops through three progressive stages: first, having experienced good products and built a perceptual sense; second, participating in creating good products to understand collaboration; third, leading the development of good products and taking responsibility. Examples such as a well‑designed class, an efficient meeting mechanism, or a viral social‑media video illustrate that any experience can be treated as a product. Without taste, even strong data analysis yields merely correct but mediocre outcomes.

2. Penetrating Three Worlds

A product manager must master three layers of insight. Human nature : reading users’ unspoken anxieties (e.g., students dislike forms because they crave respect). Social operation : grasping the logic behind rules and institutions (e.g., why school management systems resist change due to entrenched resource‑allocation habits). Business model : understanding how value flows and how free tools can sustain a team. The author notes that a product manager’s role is essentially the same as a CEO’s—full responsibility for a product from feature iteration to ecosystem construction.

3. Imagination × Judgment × Interdisciplinary Thinking

The third key combines imagination, judgment, and cross‑disciplinary knowledge (such as aesthetics and psychology). Good products consist of two layers: the foundation layer , which meets needs and improves efficiency (e.g., streamlining a check‑in process); and the breakthrough layer , which shatters cognitive boundaries and ignites creativity (e.g., the iPhone redefining what a phone can be). Achieving this requires sociological insight into human blind spots, economic reasoning about resource trade‑offs, and artistic thinking to reconstruct experiences.

Ultimately, a product manager’s mission is not merely to deliver features but to expand the boundaries of the world. When one applies product thinking to a lesson, a relationship, or a conversation, they gain the power to reshape small universes.
