This Is Service Design Doing: Applying Service Design Thinking in the Real World: Summary & Key Insights

Service design starts with a mindset. Before we dive into methods, we need to understand what it means to approach challenges as designers of experiences rather than products. In our practice, we describe service design as the human-centered, iterative process of creating systems that serve people effectively and delightfully.

The Double Diamond model is a cornerstone of this process. It reminds us that good design oscillates between divergent and convergent thinking — between exploring widely and narrowing down with intent. The first diamond, 'Discover,' opens the field: we question assumptions, seek patterns, and immerse ourselves in users’ worlds. The second diamond, 'Define,' helps us consolidate those insights into clear problem statements. Then comes 'Develop,' where we generate ideas and prototype solutions, followed by 'Deliver,' where we test, refine, and implement outcomes in real contexts.

But applying the Double Diamond requires more than following phases mechanically. It demands flexibility and contextual awareness. In our workshops, we often emphasize that the model is not a rigid template but a language for collaboration. Each organization, each team, will adapt the rhythm and scale of the diamonds based on their resources and culture.

When teams begin thinking in this way, the design process becomes less about individual creativity and more about collective discovery. We encourage participants to visualize every step — from research to prototyping — so that decisions are shared, not hidden in reports. In the real world, visibility is power: when stakeholders see the journey, they understand why choices are made and become allies in the implementation of design-led change.

Service design operates through a set of core principles that form our professional compass. Co-creation is the first and most fundamental. Every service is co-produced — not only between provider and consumer but among teams, departments, and even technologies. In our experience, the best ideas emerge when people who never talk to each other start designing together. Co-creation workshops create spaces where differences in perspective transform into insights.

Sequencing means understanding service as a journey through time. Services unfold in steps, moments, and transitions. By mapping sequences, we discover where user experience breaks down or where emotions peak. Designing these sequences lets us guide people smoothly across touchpoints, reducing friction and enhancing satisfaction.

Evidencing is about making the intangible visible. Many service interactions happen invisibly — a database updates, a system approves a request, or an employee takes internal action. Evidencing turns these invisible actions into cues that reassure the user something is happening. A simple confirmation message or a thoughtfully designed receipt can change the entire perception of a service’s reliability.

Holistic thinking ties all these together. It challenges teams to see beyond single touchpoints. A service is never isolated — it’s embedded in contexts, infrastructures, and relationships. Holistic design asks, how do policies, physical spaces, technologies, and human behaviors align to support the intended experience? Without this systemic view, improvements at one moment can cause problems at another.

Through co-creation, sequencing, evidencing, and holistic thinking, we design not just for usability but for empathy. We make services that feel intentional, trustworthy, and easy to navigate — services that respect people’s time and emotions.
