Mobile ActivationPlatform Redesign
The tool had 12 screens, no progress indicator, and timed out mid-transaction. Staff had memorized workarounds just to survive a live sale. I went to the stores, watched it happen, and fixed it.
The activation tool had 12 screens, no progress indicator, and timed out mid-transaction — managers had memorized workarounds just to survive a live sale. I mapped the full workflow, ran usability tests across 3 rounds, and redesigned it into a 4-step flow with inline validation and auto-save — cutting activation time from 12 to 4.5 minutes and dropping the error rate by 74%.
The Challenge
RT2 is a payment processing company that facilitates mobile activation and payment collection for store users based on their phone carriers. The existing workflow required users to navigate through multiple complex screens, creating friction in both the activation process and payment collection.
The challenge was to streamline the entire workflow, making it intuitive and simple to expedite the process without requiring numerous screens or clicks.
Complex Workflow
Too many screens and clicks slowing down the process
Mobile Activation Friction
Complicated activation flow causing user frustration
Payment Collection Issues
Inefficient carrier-based payment processing
Project Details
Discovery
Understanding the landscape through stakeholder interviews to identify key pain points in the mobile activation workflow.
Stakeholder Insights
I conducted 16 stakeholder interviews across store operations, customer support, sales, and IT teams to understand internal perspectives on activation workflow challenges.
Store Managers
"Staff spend too much time on each activation, causing long customer wait times"
Customer Support
"Most calls are about activation failures and payment processing errors"
Sales Team
"Complex workflow leads to abandoned activations and lost sales"
IT Operations
"System timeouts and carrier API failures cause 30% of support tickets"
Key Themes Identified
Workflow Complexity
Too many screens and steps to complete activation
Payment Friction
Carrier-based payment collection causing errors
System Reliability
Frequent timeouts and API failures
Training Gap
New staff struggle with complex interface

User Personas
Marcus Thompson
32 • Experienced Sales Rep
- Complete activations quickly
- Minimize customer wait time
- Hit daily sales targets
- Too many redundant screens
- System crashes during peak hours
- Can't see all carrier options at once
"I know the system inside out, but it still takes too long. My customers shouldn't have to wait."
Sarah Mitchell
24 • New Store Associate
- Learn the system quickly
- Avoid making errors
- Get help when stuck
- Confusing navigation
- No clear guidance on next steps
- Fear of making costly mistakes
"I'm always worried I'll mess something up. The training didn't prepare me for all the edge cases."
David Chen
45 • Store Manager
- Maximize store efficiency
- Reduce support escalations
- Train new staff effectively
- High error rates from new hires
- Time spent troubleshooting
- Inconsistent carrier processes
"I spend more time fixing activation issues than actually managing my store."
Marcus was mid-activation when the session timed out — customer watching, no way to recover, restart from scratch. Sarah had just called David over for the third time that shift because an error code told her nothing. Three people, three different problems — but they all traced back to the same four design failures.
Lock the flow
Marcus persona — free navigation let staff skip steps, causing the majority of errors. He'd memorized a workaround order that new hires didn't know.
Always show where you are
Sarah persona — no progress indicator meant she had no idea how many steps remained. When errors hit, she'd abandon and restart rather than continue.
Errors must explain themselves
David persona — new hires called him over for every error code. He kept a handwritten cheat sheet under the counter. That's a training failure caused by the UI.
One flow, not two systems
All three personas — payment and activation in separate systems meant tab-switching and manual copy-paste on every single transaction. Observed in 100% of shadowed sessions.
These 4 requirements became the non-negotiable constraints for every screen in the prototype. See how each one was implemented →
The Transformation
Before & After
The original flow had 12 separate screens — one field per page. We consolidated it into 4 grouped steps with inline validation. Here's what changed and why it mattered on the store floor.
Before — 12-Screen Flow
One field per screen, no grouping
What staff experienced
- Constant back-and-forth navigation with a customer watching
- No validation until final submit — errors sent you back to step 1
- No sense of progress; staff couldn't tell how far along they were
- Average completion time: 8–12 minutes per activation
- ~42% of submissions had at least one error requiring rework
After — 4-Step Grouped Flow
Related fields consolidated, inline validation
Device Information
IMEI, SIM, device type, carrier — all on one screen
Customer Details
Name, email, phone, address grouped together
Plan Selection
Visual plan cards with side-by-side comparison
Review & Activate
Full summary with one-tap confirmation
What changed for staff
- Related fields grouped — fewer page loads, less back-and-forth
- Inline validation catches errors as you type, not at the end
- Persistent step indicator shows exactly where you are
- Average completion time dropped to 2–3 minutes
- Error rate fell to ~8% — an 81% improvement
Why these decisions were made
Information Grouping
Card sorting sessions with branch managers revealed that staff mentally grouped device info and customer info as two separate tasks. The redesign mirrors that mental model.
Progressive Validation
Errors at final submission were the single biggest frustration. Inline validation was added so staff get feedback immediately — before the customer is still standing there waiting.
Visible Progress
Shadowing sessions showed staff losing track of where they were mid-activation. A persistent step indicator was added so the flow always felt predictable and in control.
Smart Defaults
Carrier context was already known at login. Pre-populating carrier-specific fields and filtering plan options reduced manual input and decision fatigue during busy floor hours.
From Research to
Design Decisions
Every screen decision traces back to a specific observation from the store floor. Here's how the research translated into the actual interface — from first sketches to the final prototype handed off to engineering.
Wireframe Progression
Three rounds of prototyping, each tested with real store staff. Each round addressed the specific failures of the round before it.
Collapsed 12 original screens into a 4-step linear model. Grouped device info (IMEI + SIM + carrier) onto a single screen instead of 3 separate ones.
Staff immediately understood the grouped layout — but carrier selection at the bottom caused confusion. Everyone expected it at the very top to set context for the whole flow.
4 Decisions That Defined the Design
Each one traces directly to a specific observation from the store floor — not a best practice, not a heuristic, but something I watched happen in front of a real customer.
The original system let staff navigate freely between steps — which meant they could (and did) skip steps, causing the majority of activation errors. New hires had no idea what order things needed to happen in.
A strictly locked linear flow: step 1 → 2 → 3 → 4. You cannot proceed until the current step is valid. The UI enforces correct order structurally — not through training.
Activation error rate dropped from 34% to under 8% in round 2 testing. The locked model had the lowest error rate across all 4 flow structures tested.
Before & After: Activation Start Screen
The screen staff see first — and the one that set the tone for every interaction that followed. Toggle between the original and redesigned version.
- Carrier selection buried at step 3 — staff had to guess plan options before knowing the carrier
- No progress indicator — staff had no idea how many steps remained
- Session timeout at 5 min with no warning — mid-activation restarts were common
- Generic error codes (4402, 5011) with no explanation or recovery path
- Payment in a completely separate system — required tab switching and manual copy-paste
