Secondary research, also called desk research, involves gathering and synthesising information that already exists: academic papers, industry reports, competitor analyses, market data, and previous internal research. It is almost always the right starting point for any new project because it prevents teams from rediscovering what is already known and helps frame the primary research that follows. A strong secondary research phase can save weeks of fieldwork by sharpening the team's focus on genuine unknowns.
What It Is
Secondary research encompasses any data or findings that were collected for a purpose other than your current project. Sources range from peer-reviewed academic literature and government statistics to trade publications, news articles, online reviews, forum discussions, and existing internal reports. The researcher's job is to locate relevant sources, evaluate their credibility, synthesise their findings, and distil the implications for the current design challenge. The output is typically a research brief or literature review that grounds the team in the current state of knowledge.
How to Run It
Start with a clear research question or set of unknowns. Search academic databases such as Google Scholar, industry publications, and trusted news sources. Use a structured note-taking approach to capture source, key finding, and relevance for each piece you review. Look for convergence across multiple sources: a finding that appears in three independent studies is more reliable than one that appears in only one. Organise your findings into themes and write a synthesis that highlights implications for your design challenge, not just a summary of what you found.
When to Use It
Secondary research should happen before any primary research, at the very start of a project. It is also valuable between research phases, when new questions arise and the team wants to check whether answers already exist before running new studies. For design teams working in regulated industries such as healthcare, finance, or education, secondary research is essential for understanding compliance constraints and established best practices.
Tips for Success
Evaluate every source critically: check the date, the methodology, the sample size, and the potential bias of the publisher. Avoid citing opinion pieces as if they were data. Grey literature, such as industry association reports, can be valuable but varies widely in rigour. Keep a running bibliography from the start of a project so citations are easy to retrieve later. Share findings with the whole team in a visual format like a one-page summary or themed affinity diagram rather than a dense report.
