Co-Discovery Testing

Co-discovery testing is a UX method involving pairs of participants testing a product together, enabling the discovery of new ways of use and usability issues by leveraging their natural interactions.


Codiscovery Testing is a usability testing method where two participants explore and interact with a product together. By observing how they collaborate, communicate, and problem-solve, researchers gain insights into usability, learnability, and collaboration within the system. Codiscovery Testing can reveal how users naturally explain features to each other, uncovering potential areas of confusion. It's valuable in designing collaborative tools or complex systems where user interactions are multifaceted.

Suitable for

  • Physical and digital artifacts,
  • Testing products for younger generations,
  • Later iterations of testing.


Test Plan

Test Script

A written guideline that includes the step-by-step tasks to be performed by the participants during the co-discovery testing session. The script helps ensure consistency across participants.

Participant Consent Forms

Signed forms that inform participants about the purpose of the study, confidentiality of their information, and their rights during the co-discovery testing session.

Data Collection Tools

Various tools used during the co-discovery testing process to capture user interactions, thoughts, and feedback, including video and audio recording devices, notepads, and questionnaires.

Data Analysis Framework

A planned approach for analyzing the collected data using qualitative and quantitative methods such as affinity diagramming, content analysis, or behavioral coding.

Findings and Recommendations Report

A comprehensive report detailing the major findings, patterns, and insights drawn from the analysis of the data collected during the co-discovery testing sessions. The report also includes actionable recommendations to address the identified UX issues and opportunities for improvement.

Test Results Presentation

A distilled visual presentation of the key findings and recommendations from the co-discovery testing report, tailored for sharing with stakeholders and project team members.

Screener Survey

A set of pre-screening questions used to identify and recruit suitable participants for the co-discovery testing sessions, ensuring that they match the target user demographic and profiles.

Participant Scheduling and Logistics Management

A process or system for scheduling and coordinating participant sessions, including details such as location, timing, incentives for participation, and communication with participants.

Participant Debrief and Thank You Cards

A brief one-page document or card expressing gratitude to the participants for their time and valuable feedback during the co-discovery testing session, often incorporating an overview of study results or next steps based on the findings.



Define Objectives

Start by identifying the primary goals of your Co-Discovery Testing, including specific functionalities or aspects of the product that you want to assess. Be sure to clearly communicate these objectives to your team.


Select Participants

Choose a diverse group of participants who fit the target user demographics for your product. Aim for 4–6 pairs (8–12 people total), including a mix of novices and experts, or users with different background experiences.


Create Test Scenarios

Develop a set of realistic scenarios or tasks that individuals will need to accomplish using your product. These scenarios should cover key functionalities and user needs, aligning with your objectives. Be descriptive and detailed, providing context for the testers.


Introduce the Discovery Process

Explain to the participants how the Co-Discovery Testing process will work, detailing their roles, the dynamic of working in pairs, and the expected sharing of ideas and insights. Encourage them to ask questions and clarify any doubts.


Pair Participants

Pair participants together, considering the balance of knowledge and skills among them. Encourage productive conversation and collaboration during the testing process, ensuring that they are comfortable openly exchanging opinions and suggestions.


Conduct the Testing Sessions

Have participants work through your test scenarios as a pair, completing tasks while concurrently discussing their impressions, difficulties, and ideas for improvement. Encourage them to share their thoughts and feedback out loud throughout the session.


Observe and Record

During the testing sessions, have a moderator observe each pair of participants, noting their interactions with the product and with each other. Capture both verbal and non-verbal feedback, as well as any struggles, successes, or insights that emerge.


Conduct Debriefing

After the testing sessions, gather the participants to discuss their experiences and share any notable findings. This group discussion allows for additional insights and potential improvements to be identified and shared among the group.


Analyze Results

Review the data collected during the sessions, including observations, participant discussions, and debriefing notes. Analyze the findings to identify patterns, themes, and areas for improvement in the user experience.


Report Findings and Recommendations

Create a comprehensive report that outlines the key findings from the Co-Discovery Testing sessions, as well as actionable recommendations for improving the overall user experience. Share the report with your team and stakeholders for implementation of improvements and future testing.
