LECTURE 16

Overview

This lecture explains how design thinking and user experience (UX) practices apply to healthcare products and services. Topics covered include high-level design-thinking phases, concrete UX components and principles, accessibility and cross-platform concerns, research methods, empathy techniques (including empathy maps), a structured design framework (Double Diamond), and a UX case study (HealthPal).

Main ideas and concepts

Design thinking sequence

1. Empathize — understand users using personas and empathy maps
2. Define — clarify the problem space and target segments
3. Ideate — generate ideas and value propositions
4. Customer discovery — test value propositions with users
5. Prototype — design and build prototypes
6. Test — iterate based on user feedback

Product-design orientation types

• Universal design: One-size-fits-most products usable by a broad population (e.g., masks, shoes, common stents).
• Inclusive design: Designed for a primary group but usable by others (e.g., a glucometer made for older adults but also used by pregnant women and younger obese users).
• Equity-focused design: Intentionally addresses historically underrepresented or diverse user groups by adapting to different needs (example: adjustable viewing height so adults, teens, toddlers can all see).

Accessibility (design for people with disabilities)

Consider:

• Limited limb use — one-arm interactions and simplified physical controls.
• Limited vision — braille, audio cues, and assistive devices (e.g., a smart cane with proximity sensors).
• Limited hearing — strong visual cues and vibration feedback.
• Limited speech — sign language support or alternative input methods. Also allow options/settings to accommodate situational, temporary, or permanent impairments.

Cross-platform design considerations

• Device variety and screen sizes: phones, tablets, desktops, smartwatches.
• Functionality and payment options: cash, digital wallets (Paytm, Google Pay), credit cards.
• Interaction simplicity: minimize taps and reduce friction.
• Content layout and presentation: same content can be laid out many ways; prioritize clarity and visual hierarchy.

Key UX principles

• Consistency: predictable behavior and visuals across screens.
• Continuity: avoid jarring transitions (e.g., unexpected immediate payment prompts).
• Complementarity: companion services/apps should genuinely complement the product.
• Context: keep content, offers, and navigation relevant to user intent and product theme.

Designing for the “next billion” users

• Account for cost sensitivity, limited connectivity, diverse devices, and varied digital literacy.
• Build trust and simple, reliable experiences rather than treating new users as mere data producers.

UX research methodology

UX research fits three layers in the product cycle:

Foundation research (early / discovery / customer discovery)

Methods:

• Interviews, surveys, focus groups
• Competitive audits, field studies, diary studies Purpose: build raw understanding; surface pain points and opportunities

Design research (during ideation and prototyping)

Methods:

• A/B testing, hypothesis-driven tests, simulated tests, guerrilla studies
• Card sorting, usability evaluations, wireframe tests Purpose: iterate on designs; validate interaction patterns and content priorities

Post-launch research (after soft launch / scaling)

Methods:

• A/B testing, usability studies, surveys, log/analytics analysis Purpose: monitor real-world usage, detect issues, guide incremental improvements

Empathy and user understanding techniques

General guidance:

• Ask many questions; observe actual behavior.
• Seek genuine feedback (including negative).
• Be an active listener, keep an open mind, and stay current on UX research.

Empathy maps — four quadrants to profile a persona:

Says — direct quotes or stated needs (e.g., “I want convenience”) Thinks — internal thoughts or beliefs (e.g., “I don’t have time for long lines”) Feels — emotions (e.g., impatient, overwhelmed) Does — observable behaviors (e.g., drinks coffee daily, heavy smartphone use, walks to work)

Use affinity mapping to synthesize survey and interview data and derive personas and actionable insights.

Interviewing stakeholders

Conduct structured interviews with the right stakeholders to surface constraints and decision criteria:

• Technical buyers
• Clinicians and clinical staff
• Procurement staff Purpose: uncover practical constraints, grievances with existing solutions, and procurement/clinical decision drivers.

Design framework — Double Diamond example

Four phases:

1. Discover — surveys, user interviews, affinity maps, competition analysis, usability evaluation
2. Define — synthesize findings into problem statements, business requirements, user stories, personas, user journeys/flows
3. Develop — card sorting, content audit, sitemaps, sketches, mid- & high-fidelity wireframes, usability test plans and iterations
4. Deliver — style guides, high-fidelity prototypes, final design presentations, and handoff for launch

Case study: HealthPal (UX/UI mobile health & wellness booking assistant)

• Project goal: design a healthcare booking/consultation assistant for users who need expert medical advice but lack immediate personal referrals.
• Target demographic: roughly ages 18–40 (young adults and working-age adults).

Discovery steps used:

• Surveys and interviews targeting people who sought professional advice online (~20 responses in the cited example).
• Synthesized results with affinity mapping.
• Built personas and organized insights under participant goals, frustrations, common practices, competitors, and appointment/consultation workflows.

Key findings:

• Health & wellness was a top category when people sought professional advice.
• Satisfaction with past online professional advice varied — a notable fraction were dissatisfied, indicating opportunity.
• Personas and insights guided flows, content, and feature priorities.

Concrete examples and anecdotes used

Devices and products referenced:

• Stents (medical device example for universal design)
• Glucometer (inclusive design example; requires more technique)
• Digital thermometer (equity-focused example: two-button simplicity)
• Mask, face shield, shoes (universal-design examples)
• Smart cane from IIT Delhi (assistive tech for visually impaired; proximity sensor/beeps)
• Smartwatch syncing issues (cross-platform and cross-border complexity)

Services and other examples:

• Payment apps: Paytm, Google Pay (usability differences across age groups)
• Amazon (returns and customer behavior)
• Distribution issues: shipping delays for pharmaceuticals, cash vs digital payments, credit-card purchasing behavior

Lessons and practical takeaways for healthcare entrepreneurs

• Start with empathy and validated customer discovery before building features.
• Decide early whether your product should be universal, inclusive, or equity-focused.
• Build accessibility into products where feasible (account for situational and permanent disabilities).
• Make digital products cross-platform and minimize friction (screen sizes, local payment options, offline scenarios).
• Prioritize clarity via consistency, continuity, complementarity, and contextual relevance.
• Design for scale and diverse users (cost, connectivity, digital literacy), not just early adopters.
• Use layered UX research (foundation, design, post-launch) aligned to the development cycle.
• Translate qualitative insights into design decisions using empathy maps and personas.
• Engage the right stakeholders early to surface procurement and clinical constraints.
• Follow a structured, iterative design process (e.g., Double Diamond).
