How User Research Fuels Effective Design: Key Insights and Practices

Having worked as a user researcher in both traditional and internet companies, the author shares how user research connects with design.

What user researchers do daily

Generally they either learn about others' lives or write reports. In both traditional and internet industries, researchers act as a medium, gathering and filtering information, helping product managers or designers understand behavior and needs, avoiding bias.

How does it relate to design?

Design discovers problems, analyzes questions, and solves problems. User research supports this process.

1. Understand design basics

Without knowledge of design or product, researching users is passive because users' lives are multifaceted and change over time. Researchers must focus on specific people and behaviors within limited time, aiming to solve problems, so they first need to understand what product managers and designers need to solve.

2. Uncover design requirements

Research is not limited to “new product, new feature, go test users” or “what are users concerned about, go research”. When a need arises, the user who raises it is the requester. Researchers communicate thoroughly with stakeholders and may use basic research methods to achieve equal understanding. For example, usability testing is common, but without equal insight into interaction updates, researchers may miss new habits and focus only on task flow.

3. Actively participate in design

Methods such as IDEO Method Cards (51 innovation cards) serve two main purposes: 1. Understand users' choices and 2. Understand the reasons behind those choices (quantitative and qualitative). Knowing choices helps quickly judge design proposals; knowing reasons helps solve problems more appropriately.

Research also balances constraints. In a fridge project, designers proposed a transparent fridge because research showed users spent time searching inside, but researchers opposed it for mass users due to clutter and energy waste, while suggesting it for high‑end users who store premium items and appreciate visibility.

User research as part of design

Research results should be understandable to everyone, e.g., insights about post‑95 culture, QQ usage patterns, and visual style preferences among female users.

Italian designer Massimo Vignelli said, “I don’t trust market research. In the US, market research aims to know what users want, not what they truly need. People hardly know what they need.” This highlights that user research must go beyond conventional methods to uncover real needs.

In summary, user research exists throughout all design stages and actively participates in shaping design solutions.
