Excellant Usability Score
82.1 SUS (A) from 18 participants validates excellent usability and user delight.
Context
Immersed in Philips’ design culture, studied peers, synthesized insights into a clear problem statement.
What is CAD?
CAD is artery narrowing that reduces heart blood flow, causing angina and heart attacks.
Symptoms
Symptoms include angina, breathlessness, fatigue, palpitations, dizziness, nausea, and heart attack.
Risk factors
Risks include smoking, high BP, high LDL, diabetes, obesity, unhealthy diet, age, family history, & male sex.
Problem Statement
How might we create a comprehensive solution to reduce the risk factors linked to CAD among Indian adults, considering its potential for heart attacks and cardiac arrests?
Research
Defined research questions, reviewed literature, analyzed competitors, identified gaps, & crafted user interview questions.
Literature Review: Insights
Actionable insights from reviewing 141 literatures
CAD Risk Factors
A sedentary lifestyle, poor diet, metabolic conditions, and inequities elevate CAD risk in Indians 30+.
Stress Management
Managing chronic stress and mental health reduces behaviors and physiologic drivers linked to CAD.
Culture & Society
Promote healthy diets, address socioeconomic gaps, and lower cultural barriers to regular activity.
Tech Interventions
Digital self‑monitoring and nudges can support behavior change and targeted prevention at scale.
Environmental Factors
Pollution, limited green spaces, and urban design influence cardiovascular risk profiles.
Device Risk Classification
Competitor Research
Comprehensive competitor analysis and benchmarking
User Interviews
Systematic approach towards conducting 18 interviews
Gaps to questions
Literature and competitor reviews answered early questions and exposed gaps reframed as new questions.
Objectives
Those questions defined interview objectives, target participants, and a focused discussion guide.
Questionnaire
Objectives shaped clear, phased questions to ease participants and surface honest insights.
Analysis
Transcribed interviews in Excel, built an inductive codebook, distilled four themes, and produced user stories, stakeholder maps, and a persona revealing CAD prevention opportunities.
“As is” User Story
Lifecycle of a typical CAD patient (pre-diagnosis)
Phase 1/4: College Life (18-23Y)
Poor diet, long sitting, late nights, smoking or alcohol, and ignored self care dominate.
Phase 2/4: Starts professional life (24-27 Y)
Work disrupts meals, extends sitting, adds parties, increases alcohol or smoking, and neglects self care.
Phase 3/4: Marries and starts a family (28-32 Y)
Diet improves slightly, but sitting persists, stress rises, weight increases, BP and cholesterol emerge, self care slips.
Phase 4/4: CAD symptoms starts (35+ Y)
Better diet and walks start, less alcohol or smoking, chest pain leads to tests and treatment.
