Notes on Design, Design Thinking, and Service Design

Design and Innovation: Key Concepts

  • Design innovation definition: focuses on addressing people's needs with what is technologically feasible and advising a viable business strategy to derive value from this market opportunity.
  • The 3-circle model (desirability, feasibility, viability): 33 circles with the center representing the area where all three overlap
    • Desirability: Do people want it?
    • Feasibility: Can it be made?
    • Viability: Can it be sold / sustain a business?
    • The core question: Do people want it, can it be made, and can it be sold?
  • Innovation philosophy (Buckminster Fuller): "you can never really change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete." In other words, change comes from creating new approaches rather than opposing the old ones.
  • Design as doing: "design is the ability of thinking by doing" — you must act to make things happen; thinking alone doesn’t produce outcomes.
  • Design-focused areas: various disciplines and transdisciplinary approaches; design for services as a field of focus.
  • Change levels in design:
    • Design for service today: moderate change
    • Design for social innovation: significant change (affecting people)
  • Transition design and systems change: larger, end-of-semester topics; focus on changing entire systems and long-term transitions.
  • Service design definition: creative application of design thinking methods to the development of services; existing services can be improved or entirely new services created, often involving digital technology.
  • Services and technology examples in daily life:
    • Restaurants as a service
    • DoorDash and other delivery platforms
    • Waste management as a service
    • Phone apps and digital services that alter traditional services
  • Services account for a large portion of the world’s GDP: services are prolific and central to modern economies.
  • Service design involves collaboration across disciplines and follows a flexible process rather than a single fixed procedure.

What is Service Design? (Core Definition and Scope)

  • Service design is the practice of making services better through research, developing ideas, and testing experiences.
  • It applies design thinking methods to service development, often with digital technology as a key enabler.
  • Readiness examples to anchor understanding:
    • DMV experience often being frustrating due to long waits
    • The idea that services exist across product-based and intangible domains (e.g., online videos, car mechanics, in-store shopping, education, health care, government services)
  • Services are pervasive and affect many areas of life; they can range from simple to highly complex.
  • A service can be a product-based service (e.g., a delivery app) or a purely intangible service (e.g., a healthcare service).
  • The goal of service design is to improve the overall experience for all involved, not just the end user but also providers and the broader society.

What Do Service Designers Do? (Process Overview)

  • Core approach: begin by talking to everyone involved with or affected by the service (collectively called stakeholders) to understand their ideas of an ideal experience.
  • Stakeholders include anyone affected by the service (e.g., DMV staff, government officials, customers, road users).
  • After gathering stakeholder input, compile the research to get a complete bird's-eye view of the current service and identify what is required to satisfy the needs and motivations of each group.
  • Define the design goal based on findings (example goal provided):
    • Goal: Empower efficient employees and informed customers, leading to a faster, simpler DMV experience and safer roads for everyone.
  • Ideation: generate a variety of ideas with stakeholders about how to improve the service.
  • Prototyping: test the most promising ideas using service prototypes (mockups) that allow people to experience interactions with new service aspects.
    • Examples of prototypes: different appointment options, express lines to reduce wait times, or small changes like providing free coffee, Wi‑Fi, and a comfortable lounge to test impact on the waiting experience.
  • Testing and iteration: repeat the prototyping and testing phases to better understand problems, refine ideas, and consolidate them into a complete service solution.
  • Implementation planning: at the end, share the redesigned service with stakeholders and provide a plan for implementing, sustaining, and evolving it.

Service Prototype Details and Real-World Examples

  • Prototypes enable experiential testing of new service elements before full rollout.
  • Real-world testing helps determine which changes most improve the user experience and operational efficiency.
  • Stakeholders’ feedback is essential to ensure the service meets diverse needs and constraints.
  • The goal of prototyping and testing is to arrive at a service that is desirable, enjoyable, effective, and efficient for providers, consumers, and society.

Expected Outcomes of Good Service Design

  • When done well, service design outcomes are:
    • Desirable for users
    • Enjoyable in experience
    • Effective in achieving outcomes
    • Efficient for providers, consumers, and society
  • The analogy used: service design can feel like a constructive group therapy session—collaborative, empathetic, and aimed at improving collective well-being.

Stakeholders and Their Roles

  • Stakeholders: anyone with a stake in the service; broad category including staff, customers, government entities, and people affected by the service.
  • Examples from the DMV context:
    • DMV employees
    • Government officials
    • Customers who use the service
    • Road users and others affected by the DMV process and related services
  • The stakeholder map informs who to interview, what needs matter, and how to measure success.

Connections to Foundational Principles and Real-World Relevance

  • Design thinking and service design connect to broader principles: user-centered focus, iterative testing, cross-disciplinary collaboration, and alignment of user needs with feasible technology and viable business models.
  • Practical relevance: service design is applied across numerous sectors (government, health care, education, retail, transportation, digital platforms) to improve experiences and outcomes.
  • Ethical and social implications: designing for people implies considering accessibility, equity, and safety; social innovation represents a deliberate shift toward changes with meaningful societal impact.
  • The shift from incremental improvements (moderate changes) to systemic transformations (transition design and systems change) reflects the scale at which design can influence society and infrastructure.

Quick Definitions (Recap)

  • Desirability: user wants and needs
  • Feasibility: can be built with current capabilities
  • Viability: sustainable business model
  • D ∩ F ∩ V: the central space where desirable, feasible, and viable intersect; the sweet spot for innovation
  • Service design: applying design thinking to services, often leveraging digital technology to improve experiences
  • Transition design: large-scale system changes over time
  • Systems change: transformation of the entire system, not just individual services

Note: Ethical and philosophical considerations are hinted at through the emphasis on people-centered design and social innovation, but explicit ethical discussions are not deeply elaborated in the provided material. The emphasis remains on designing for people and improving societal well-being through iterative, collaborative processes.
