Co-discovery Sessions
A practical research method for understanding collaboration, shared reasoning, and how people make sense of things together.
How to use co-discovery sessions to observe collaborative behaviour, richer verbalisation, and how shared understanding develops in real time.

Co-discovery sessions are useful when the interaction between people tells you as much as the task itself.
When to use it
Use this method when collaboration or shared understanding is part of the experience.
It is most useful when:
It is less useful when:
Co-discovery sessions are often used alongside usability testing and interviews to provide both behaviour and reasoning.
Key takeaway
Use co-discovery when collaboration itself is part of the behaviour you want to understand.
How to run it
Set up properly
Be clear on the tasks, whether participants should already know each other, and how collaboration fits the real glossaryContextContext is the set of surrounding conditions that shape how someone behaves and decides, including their goal, their environment, their time pressure, and what happened immediately before. The same action can mean different things in different contexts.Open glossary term. Pairing people who would never work together produces an artificial dynamic.
Choose tasks with enough substance to discuss. Trivial tasks produce narration rather than reasoning.
Run the method
Co-glossaryDiscoveryDiscovery is the phase of understanding problems, users, and opportunities before building solutions.Open glossary term puts two people through a task together. Because they explain themselves to each other rather than to you, you hear reasoning that a think-aloud protocol never surfaces.
- Introduce the task and make clear they should talk to each other, not to you.
- Encourage genuine conversation, including disagreement about what to do next.
- Let them work through the task together, and tolerate longer silences than feels comfortable.
- Observe how they explain, question and decide. The explanations one gives the other are the glossaryMental ModelA mental model is the way users understand how a system works based on their past experiences and expectations. It shapes how they predict interactions and outcomes.Open glossary term, stated aloud without prompting.
- Intervene only to keep things moving. Every intervention converts the glossarySessionA session is a single period of user interaction with a product, from entry to exit within a defined timeframe.Open glossary term into a moderated test.

Capture and make sense of it
The value comes from naturally verbalised reasoning. After the glossarySessionA session is a single period of user interaction with a product, from entry to exit within a defined timeframe.Open glossary term, document:

It helps you see how understanding is formed, not just what people do.

FAQ
Common questions
A few practical answers to the questions that usually come up around this method.
What are co-discovery sessions in UX?
Co-discovery sessions are a research method where two participants complete tasks together while discussing their actions and decisions.
When should you use co-discovery sessions?
Use them when collaboration is natural or when you want more verbal insight than individual sessions provide.
What is the difference between co-discovery and usability testing?
Co-discovery involves two participants working together, while usability testing typically involves one participant working alone.
Should participants know each other?
It depends. Familiar participants may collaborate more naturally, but unfamiliar pairs can reveal different behaviours.
Are co-discovery sessions better than individual sessions?
They provide different insights. Co-discovery reveals interaction and discussion, while individual sessions show independent behaviour.
Quick take
If you want to see how people figure things out together, not alone, run co-discovery sessions.
