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.

Presented with the "LinkedIn for AI" problem, the designer's first step isn't visual design. It's product strategy: clarifying the core objective (e.g., matchmaking, certification), identifying the target user groups (job seekers, employers), and defining what "a good match" even means in this new context.

Relying solely on data leads to ineffective marketing. Lasting impact comes from integrating three pillars: behavioral science (the 'why'), creativity (the 'how' to cut through noise), and data (the 'who' to target). Neglecting any one pillar cripples the entire strategy.

Many teams wrongly focus on the latest models and frameworks. True improvement comes from classic product development: talking to users, preparing better data, optimizing workflows, and writing better prompts.

Structured analysis works when you can theorize potential causes and test them. However, for problems where the causes are "unknown unknowns," design thinking is superior. It starts with user empathy and observation to build a theory from the ground up, rather than imposing one prematurely.

Users aren't product designers; they can only identify problems and create workarounds with the tools they have. Their feature requests represent these workarounds, not the optimal solution. A researcher's job is to uncover the deeper, underlying problem.

The effectiveness of an AI system isn't solely dependent on the model's sophistication. It's a collaboration between high-quality training data, the model itself, and the contextual understanding of how to apply both to solve a real-world problem. Neglecting data or context leads to poor outcomes.

Inspired by architect Christopher Alexander, a designer's role shifts from building the final "house" to creating the "pattern language." This means designing a system of reusable patterns and principles that empowers users to construct their own solutions tailored to their unique needs.

When handed a specific solution to build, don't just execute. Reverse-engineer the intended customer behavior and outcome. This creates an opportunity to define better success metrics, pressure-test the underlying problem, and potentially propose more effective solutions in the future.

Truly innovative ideas begin with a tangible, personal problem, not a new technology. By focusing on solving a real-world annoyance (like not hearing a doorbell), you anchor your invention in genuine user need. Technology should be a tool to solve the problem, not the starting point.

AI coding tools generate functional but often generic designs. The key to creating a beautiful, personalized application is for the human to act as a creative director. This involves rejecting default outputs, finding specific aesthetic inspirations, and guiding the AI to implement a curated human vision.
