Short answer

For any digital product aimed at a specific user group, especially those with unique needs, a co-design methodology is crucial for ensuring the product's success and relevance.

Field: User-Centred Design
Source: Journal of Medical Internet Research (2026)
Method: Participatory design and usability testing
Sample: 23 participants (1 coinvestigator + 6 lived experience members in advisory group, 10 in participatory design panel, 12 in validation group)
Evidence: Strong effect

Involving end-users throughout the development process of digital health platforms ensures the final product effectively meets their needs and integrates into their lives. This user-centred design research insight is drawn from a 2026 study published in Journal of Medical Internet Research. Using Participatory design and usability testing with 23 participants (1 coinvestigator + 6 lived experience members in advisory group, 10 in participatory design panel, 12 in validation group), researchers explored how this design variable affects real-world outcomes. The key design takeaway: For any digital product aimed at a specific user group, especially those with unique needs, a co-design methodology is crucial for ensuring the product's success and relevance.

Application

Design takeaway

For any digital product aimed at a specific user group, especially those with unique needs, a co-design methodology is crucial for ensuring the product's success and relevance.

How to apply

When developing any new digital tool or service, establish a diverse user advisory board and conduct iterative co-design workshops and usability tests with representative users.

Project actions

01Involve your target users in brainstorming and prototyping sessions.
02Use feedback from user testing to make changes and test again.

Method & Evidence

AimTo develop and validate an online peer support platform for individuals with long-term physical health conditions through a co-production process.

MethodParticipatory design and usability testing

ProcedureA four-stage co-production process (co-assess, co-design, co-validate, co-deliver) was employed, involving a research advisory group (including individuals with lived experience), a participatory design panel, and a separate group for usability testing. Methods included online focus groups, co-design workshops with software developers, think-aloud exercises, and semistructured interviews.

Sample23 participants (1 coinvestigator + 6 lived experience members in advisory group, 10 in participatory design panel, 12 in validation group)

ContextDigital health platforms for individuals with long-term physical health conditions.

Variables

IVInvolvement of end-users in co-design and co-validation processes.

DVUsability and perceived relevance of the online platform.

CVType of health condition, digital literacy of participants, software development expertise.

Strengths & Limitations

Strengths

+Inclusion of individuals with lived experience in multiple stages.
+Iterative development process informed by user feedback.

Limitations

It can be challenging to recruit a diverse and representative group of users, and managing group dynamics in co-design sessions requires skill.

Reliability & validity

Reliability was likely enhanced through multiple testing rounds and diverse feedback. Validity was strengthened by using multiple methods (think-aloud, interviews) and involving users with direct experience.

Think critically

How might the challenges of co-design (e.g., managing diverse opinions, ensuring equitable participation) be mitigated in a design project?

Design Principles

"User needs and experiences should be central to the iterative design and development process."

This approach moves beyond traditional user testing by embedding users as active collaborators from conception to validation. It leads to solutions that are not only functional but also desirable and practical for the intended audience, increasing the likelihood of adoption and positive impact.

What This Means for Your Design

When you design something for people, it's best to ask them to help you design it from the start, not just test it at the end. This makes sure it's actually useful and easy to use for them.

Paragraph starter

The development of user-centered digital solutions, particularly in healthcare, benefits significantly from co-production methodologies. As demonstrated by Jones et al. (2026), involving end-users throughout the design and validation phases ensures that the final product is not only functional but also highly usable and relevant to the target audience's lived experiences and needs.
