UX Approach
The project employed a two-phase design approach, creating dedicated mobile and tablet applications for both patients and clinicians. This ensured a tailored experience for each user group, addressing their specific needs and functionalities..
Through the Double Diamond design process, we embarked on a journey to deeply understand user needs. This led to a systematic exploration of core issues and exploration of potential solutions, which were rigorously tested through usability sessions. This iterative process allowed us to adapt and continuously improve throughout the project. As a result, the user experience that delivers satisfaction. The new design is not only simpler and more secure, but it also aligns seamlessly with user expectations.

Research
To identify the most promising digital solutions, the project was kicked off with a structured 3 months sprint for both the Patient and clinician’s app
This phase combined :
Product walkthroughs & knowledge transfer
Stakeholder & Business understanding
Secondary research
User interviews & analysis
Feasibility assessments
Feature priortisation
The sprint culminated with a rigorously discussed features and possibilities with stakeholder from key departments to mitigate risks.

Primary Research
Analyzed current App
Patient’s App
Clinician’s App
Comprehensive user experience (UX) audit of the existing application was conducted, which helped in user interview preparations and analysis of user feedback.
This process helped us identify areas where users encountered difficulties or frustrations, such as: Confusing navigation, desired features or irrelevant information.
SWOT analysis
PATIENT’s App
Used SWOT analysis in the early stage to asses client's current position and identify new areas of improvement.
This framework helped in making : Understanding bigger picture, Strategic decision-making
OLD research conducted by client
Clinician’s App
Analyzed old research conducted by client internally. This helped in widening our perspective as well as validating some of our research findings.
Competitor’s analysis
PATIENT’s App
Clinician’s App
Competitor analysis helped unveils existing prosthetic solutions, user experience trends, and helped differentiate design proposal.
Identifying Gaps, Benchmarking, Competitor’s weakness.
Literature review
PATIENT’s App
Clinician’s App
Conducted a literature review to gain insights from existing research on mobile app accessibility for amputees.
Few take away :Clear and concise language, Color contrast, Large, high-contrast text, Large touch targets, Offer multiple ways to access information etc
Secondary Research
User Interviews
A cornerstone of the UX research process, aim of the research was to have deep understanding of our target users to be able to make informed design decisions.

Key Identified Features
Phase 1
Patient’s App
Stats Visualisation
Enhancing feature most loved by Patient; various stats and reports.
Quick Access to settings
Settings are changed quite a few times in a day, which needs to be smooth experience.
Engaging Training
Training was found out to be one of the most crucial yet ignored aspect in the app.
Design for Older Adults
Majority of the users are Older adults, the app design needs to be inclusive.
Phase2
Clinician’s App
Scannable Content
Aim is to focus and send more time with the patient more than the application.
Patient Related Data
Patient’s information such as Warranty, Service etc, should be easily accessible.
Default Settings Identifier
Clinician’s found it difficult to keep track of modified and default device settings.
Prominent Visuals
As settings are most crucial aspect of the app, the visuals needs to be loud and clear.
Feature definition & Priortisation
Votes were taken from all the key stakeholders on the consolidated proposed features. Client’s Stakeholders included were :
- Design manager
- Visual designer
- Development team
- Product owners
- Marketing team
- Internal clinician’s
- Industrial product designer
- Company’s CEO
This collaborative exercise helped prioritize features and helped us strike balance between user experience, development effort, Product capabilities and business goals.
Phase 1

Phase2

Persona
It was found that there are total 4 key stakeholder; Patient, Clinician, Physiotherapist, RND team (Not considering in these phase)
Understanding Problem: Personas
1. David : 20 something man with knee amputation
“I used to feel proud and confident, but now I feel self-conscious when I walk because I think everyone is staring at me due to my awkward gait. One of the most challenging aspects of being an amputee is the feeling of vulnerability. ”
2. Sarah : Dedicated Hiker with foot amputation
“ I love to move freely between trails and terrains. Everyone refuels in a flash, but switching gears with my prosthetic takes a while, especially with my heavy rucksack. I Just wanna get moving quickly again. “
Information architecture
Process
Interim review and validation from internal clinician’s and subject matter experts
Design Approach
Home page behaves like a hub to access all the important information.
Introduced Fixed top and bottom navigation for quick access.
Crucial to do content grouping based on user needs and logical reasoning.
Introducing shortcuts to have smooth workflow experience
and more.

Mobile
As a consultant, I served as a dual-role UX researcher and designer. I also actively contributed to the visual design approach and design system’s consistency across applications.
Tablet
Managed and collaborated with diverse stakeholders and cross-functional teams, emphasizing the importance of integrating various perspectives for a holistic solution within the project constraints.
Usability Testing
I single handedly spear headed the entire testing, task design, documentation and driving insight for both the application.
Total 3 tests were performed, 2 for patient’s app and 1 for expert’s app.
Testing gave us a lot of clarity on various aspects such as :
- Perception of the application
- Navigation
- Grouping and nesting of sections
- Visual design
- Mental modal of data positioning
- and more..
Task Analysis
Users were given tasks to complete within the app. This revealed inefficiencies in existing features and identified areas where workflows can be streamlined.
A/B Testing
Tested variations of features and section nomenclature to see which version performs better with users. This helped make data-driven decisions early on during the design phase before rolling the screens out for development.
SUS Testing
The SUS questionnaire covers aspects like the ease of use, the complexity of the system, and the user's confidence in using it. Once all responses were collected, the individual scores were converted into a total SUS score, which ranges from 0 to 100. This score gave a general indication of the product's usability, with higher scores representing better usability.
