Case Study · Pervacio · 2015 — 2018
A suite of device-diagnostic products spanning retail, carrier, and enterprise — from in-store retail tools to a nationwide carrier diagnostics program, a multimode production line, and an agent on-boarding tool. Four products, one design system.
Overview
Over four years at Pervacio I designed the UX and UI for a range of device-diagnostic tools, each built for a different context across the mobile lifecycle — retail stores, carrier-scale rollouts, high-throughput warehouse production lines, and support agents. They weren't one unified design system; each was its own product, shaped around the very different people and environments it had to work in.
In-store diagnostics, trade-in, device-switch, wipe, and app loader — a full retail toolset. 2016
A carrier-scale diagnostics program deployed to 2,000 locations with Razorfish. 2015
A high-throughput production line tool testing up to 56 devices at once. 2015 — 2018

Retail — 2016
A complete in-store toolset for retail associates — bringing diagnostics, trade-in, device switching, device wipe, and app loading into a single, consistent interface. I designed the end-to-end UX and UI for each tool in the suite.
Guided, step-by-step hardware testing associates can run in front of the customer.

Bulk-loading approved apps and content onto devices before handoff.



Carrier — 2015 · with Razorfish
A carrier-scale diagnostics program designed to cut returns of fully-functional devices. Partnering with Razorfish, we designed a diagnostics experience deployed across T-Mobile's retail footprint.
Diagnostics gives associates objective evidence of a device's health, so customers keep working devices and carriers avoid the cost of processing needless returns.
Increased complexity in smart phones has led to increased customer returns on the basis of remorse, and No Trouble Found (NTF) device exchanges, which cost carriers and OEMs hundreds of millions of dollars annually. Troubleshooting devices in a retail setting is not a favored approach by frontline sales as it is time-consuming and does not generate commission. As a result, frontline reps process warranty exchanges to keep customers happy when they complain about device performance issues. 80% of the cases in which a warranty exchange is processed by the frontline, there is nothing wrong with the device hardware or software. Instead, there is simply a perceived issue which can often be resolved by updating to the recent firmware, clearing out or reducing the number of applications running, removing some data content or ensuring full battery charge.
T-Mobile set a goal to reduce No Trouble Found device returns as an opportunity for process improvement and cost reduction.
The issue is that most electronics retailers or mobile carriers lack either a sophisticated diagnostics triage proposition to help consumers better interpret perceived device quality issues, or a scheme capable of providing point-of-sale, walk-out-working solutions. Crashing, frozen applications, poor battery life and DIY misconfiguration are among the top reasons for devices being returned prematurely, but these problems remain serviceable at each touch-point throughout the customer care lifecycle, be that at a physical store location, in a call center or self-served on-device. Unfortunately, most sales agents typically lack the technical knowledge or service skills needed to diagnose devices correctly. In the face of an ever-fragmenting product base, the retailer or device manufacturer is left in the position of having to accept returned devices prematurely, increasing the cost of inventory and eroding consumer confidence in the process.
The Diagnostic tool is a customer facing, frontline rep-assisted experience that allows both automated and manual tests to be run on a customer device to identify and resolve performance issues. It reads and displays the device IMEI, identifies whether the most current firmware is loaded, and can validate whether or not there is any trouble found with the device software.
After automated diagnostics are run, Retail Diagnostics provides a summary for the rep to review with the customer and offers the ability to run additional manual tests, like checking the LCD screen, front and back camera, etc. It also offers solutions to any identified issues, such as low storage space or performance issues due to applications. It is able to flash devices back to factory settings and update to current firmware versions. When diagnostics are complete and the rep has finished reviewing resolution options.


Launch Pad / Setup Instructions
Once the Diagnostics tool is launched, setup instruction pages will guide customers through the process of connecting the device to the software in the correct way.


Select Issue
Based on the symptoms observed on the device, choose the issue category and proceed with the process flow. After the selection, the Diagnostics tool will take the customer to the education page, which shows the tests that will be performed.

Auto Tests
Auto Tests runs software tests to ensure that the device is working appropriately. The system will automatically sense the action being asked of the phone and will display the result: Pass / Fail / Improvement Suggested. This enables users to quickly detect common issues and reduces the number of returns.




Manual Tests
The system guides the customer through a series of manual tests, based on the user interacting with the device: taking pictures, adjusting levels and searching for visual cues of failures, as well as selecting Pass when the device performs without error.




Resolutions
The application will start to display the resolution messages as per the issues detected within the device. The customer can change the settings and uninstall malware apps to improve the device performance.

Summary
The summary page educates customers on how their device works and how to adjust their settings and applications, and on how their choices affect overall device health and performance.
From the two market pilots, utilization rates were in the mid 60% range, which resulted in deflecting about two million No Trouble Found devices from being returned. This equates to rough savings of over $200M. As a result, the decision was made to roll Retail Diagnostics to all retail locations and deployment to 2,000 locations began.
Enterprise — 2015 — 2018
A high-throughput production tool for warehouses and processing centers — testing up to 56 devices at once across a single lane. The challenge was scaling a clear, at-a-glance interface to dozens of simultaneous tests.
Simplify the process of completing device tests through intuitive testing workflows.


Device physical damage check can be performed easily, with advanced, illustrated images.


The tool detects devices automatically so operators can print a label for each device simply by connecting it to the tool.

If human input is necessary for defining certain information, operators will be asked simple questions.
Device GUI is designed to be simple and intuitive, so even non-native English speaking operators can perform the tests.
Powerful and well-organized dashboard reporting for workstation, platform, and operator performance.
Manage and load content to support diagnostics by allowing the customer to load content that will be used by the operator to support servicing customers.
The Guidebook provides detailed assistance of the system for the warehouse operators.
Support — 2018 · Asurion / Amazon
An agent on-boarding experience for Asurion and Amazon PC support — helping support agents get customers set up quickly and confidently. I designed the flow around a real customer story, mapping objectives to an agent-facing journey.
