Retail DX
Empowering frontline store staff with data-informed insights.

🎯 Overview
Flow is a B2B SaaS data platform for retailers in Japan. It aggregates in-store data — from POS systems, cameras, and foot traffic sensors — and delivers it through dashboards and reports.
The goal: empower frontline staff with data-informed insights to improve store performance and knowledge sharing.
I work across web and mobile, collaborating with the founder, lead engineer, customer success, and offshore dev teams to improve usability, clarity, and product value.

🔍 Background & Challenge
Japan’s retail landscape faces complex pressures: an aging population, rising e-commerce competition, and labor shortages. Physical stores need to adapt their customer experience — but many struggle due to low data literacy and high staff turnover.
Flow’s own growth had stalled, hindered by:
- A vague value proposition
- Poor onboarding
- Confusing dashboards and visualizations
In-store staff often had low data literacy and lacked tools for cross-location knowledge sharing.
🎯 Project Goals
- Define a strategy based on the company vision, business goals, and user needs
- Empower frontline staff with clear, contextual insights
- Enable internal knowledge sharing between store locations
- Improve usability, clarity, and trust through better design language and IA
🧭 Process & Approach
We followed a Double Diamond approach, adapted to a fast-moving startup context:
1. Discover: UX Audit & Research


- Audited the current product’s structure, visualizations, and usability.
- Conducted 25+ interviews with store managers across 6 retail brands to understand tasks, pain points, and context
- Synthesized findings into themes: low data literacy, high turnover, poor knowledge sharing, and siloed communication
2. Define: Framing the Problem
- Mapped key flows (e.g., report review, store comparison)
- Identified friction points and areas for design leverage
- Aligned with leadership on UX priorities and success criteria
3. Develop: Design Exploration & Prototyping
- Reorganized dashboard structure around user goals
- Introduced modular layouts with clear visual hierarchy
- Designed new visualizations tailored to the audience’s data fluency
- Prototyped and tested new flows for onboarding and navigation
4. Deliver: Ongoing Implementation & Feedback Loops
- Worked with engineers to iterate weekly on implementation
- Built feedback loops with internal stakeholders
✨ Key Design Improvement
We redesigned key parts of the experience to make insights more accessible and actionable for retail staff.
- Re-prioritized content based on user behavior and feedback
- Added clear hierarchy and scannable layouts to reduce cognitive load
- Introduced new types of visualizations tailored to user tasks
- Structured headings and layout patterns to support findability
📈 Results (Ongoing)
The project is ongoing, with promising early feedback from internal stakeholders. We're continuing to refine flows and validate improvements with users in the field.
💬 Reflection
This has been a challenging but rewarding experience — driving product clarity from within a small team, in a market with low digital maturity. It’s sharpened my ability to design for low-literacy, high-turnover environments, and to advocate for user-centered design in ambiguous, high-stakes situations.
