Human-Centred Design for Social & Behavior Change

What human-centred design adds

Human-centred design starts with a simple belief: the people facing a problem understand it better than anyone. Instead of designing for audiences from a distance, HCD designs with them.

For SBCC programs, that changes the result. Ideas are shaped by real routines, constraints and preferences. Weak ideas are dropped early, before they are expensive. And communities feel ownership of the solutions, which helps them last.

HCD is now common in donor and UN programming, and many terms of reference ask for it by name, especially for adolescent, youth and digital programs.

Our human-centred design process

We use a practical, four-phase process that fits inside our wider SBCC methodology:

• Inspiration

  Field immersion, interviews and observation to understand people's lives, needs and barriers.

• Synthesis

  Turning what we heard into insights, design principles and clear opportunity areas.

• Ideation and co-creation

  Workshops where audiences, providers and your team generate and shape ideas together.

• Prototyping and testing

  Quick, low-cost versions of the best ideas, tested and improved in several rounds.

We combine this with behavioral science. Each idea is checked against the barriers found in research and against proven principles such as making the behavior easy, attractive, social and timely.

Co-creation done respectfully

Co-creation is powerful, but only if participation is real. We take care to:

• Include the right voices. Audience members, influencers, frontline workers and, where relevant, people who are often left out.
• Make it safe. Separate sessions where power differences or sensitive topics could stop people speaking freely.
• Use accessible tools. Pictures, role play, story boards and simple models rather than jargon or long documents.
• Pay attention to ethics. Informed consent, fair compensation for time and clear feedback on what happens next.
• Close the loop. Return to participants to show how their ideas shaped the final design.

Prototyping on a budget

Prototypes don't need to be polished. A paper mock-up of an app, a role-played clinic visit, a hand-drawn poster or a simple WhatsApp flow can tell you a lot.

The goal is to learn fast: Do people understand it? Would they use it? What gets in the way? Each round of testing sharpens the idea and builds the case for investment.

When a prototype works, we help you plan a pilot with clear measures, so you know whether the solution changes behavior at scale. See our approach to monitoring and evaluation.

Where we apply HCD

• Youth and adolescent health services and platforms
• Digital tools for frontline workers and clients
• Service experiences at clinics, agro-dealers and banking agents
• Community engagement models and group programs
• Products such as savings tools, hygiene products and nutrition supplements

Guides such as the free HCD resources from IDEO.org's Design Kit are widely used in development. We bring that approach together with SBCC rigor and local knowledge of the contexts we work in.

When to use human-centred design

Human-centred design is most useful when a problem is complex, existing solutions are not working, or the people affected have very different needs from the people designing the program. It suits new services, digital tools, community activities and products. It is less useful when the solution is already well known and simply needs to be delivered at scale.

We combine human-centred design with behavioral science and SBCC theory, so that creative ideas are grounded in evidence about why people act as they do. This blend helps programs produce solutions that are both appealing and effective.

How long it takes

A focused design sprint can produce tested prototypes in four to eight weeks. Larger projects with several rounds of prototyping and piloting may take three to six months. We agree the scope and timeline with each client based on the decisions they need to make.

Who takes part

Design sessions bring together the people affected by a problem, frontline staff who deliver services, and program decision makers. Including all three makes ideas more realistic and builds ownership, so solutions are more likely to be adopted. We plan sessions around participants' time and language, and we compensate community members fairly for their time and expertise.

Common pitfalls and how we avoid them

Design workshops can look productive while producing ideas that never reach users. The most common pitfalls are skipping time in the field, inviting only staff to co-create, testing polished prototypes too late, and ignoring cost and delivery constraints. In our human-centred design work we spend time with users before any workshop, keep early prototypes rough and cheap, and invite program managers to every testing round so that feasibility is checked alongside appeal.

We also document what we learn at each round, so decisions can be traced back to evidence. This record is useful for donors, for program teams who take over the solution, and for future human-centred design projects that build on the work.
