The tension

Making the tool fast enough that staff would actually use it meant stripping away friction. Making it rigorous enough to pass grant audits meant capturing every action. Those two goals pulled against each other at every decision point, and both had to win.

01 — Context

A program built on trust that had no way to verify anything

The County of Los Angeles (LA County) Delete The Divide initiative put grant-funded laptops into the hands of underserved families across the county. Every device had to be tracked from the moment it arrived in a warehouse to the moment it was handed to a community member. The people managing this were program administrators, managers, and warehouse workers, responsible for the full lifecycle from intake to final distribution.

Shipments ranged from a single laptop to a thousand. When a new batch arrived, administrators would coordinate 8 to 14 interns to help process it. The process had three stages, and each one created a new opportunity for things to go wrong.

The manual intake process, before the app Manual · No digital record
Step 01
Shipment arrives. Nobody is notified.
Pallets of devices land in the warehouse and get stored. Administrators find out separately, often days later. The clock starts running before anyone knows there is a clock.
Step 02
Coordinate 8 to 14 interns. Schedule an intake day.
Before a single device can be verified, administrators spend time finding and scheduling enough people to process the shipment. More days pass. Devices sit.
Step 03 — Repeated for every single device
Manual verification loop. No shortcuts. No record.
Each laptop goes through the same sequence by hand, one at a time. Nothing is captured digitally at any point.
Remove from pallet Match to printed log Open device Verify serial number Test powers on Repackage Write serial on box by hand Re-stack pallets
Step 04
Move a device to a new location? Start the loop over.
Any relocation required re-opening the box and physically re-inspecting the device. No way to confirm it hadn't been tampered with between scans. No record of who touched it or when.
Every device movement triggered the full loop from scratch, with no record created at any step

“If we can't account for these laptops, it could put our entire program at risk.” — Audit Manager, LA County

LA County's grant funding required a complete "cradle-to-grave" record of every device. If the county couldn't account for a laptop during an audit, funding could be pulled, ending the program entirely.

02 — The tension

Speed without accountability would fail audits. Accountability without speed would never be adopted.

The problem had two layers that pulled against each other.

The speed problem

Avoidance

The verification process was so slow and painful that staff started hesitating to move devices at all. Any movement meant restarting the paper check from scratch. Devices sat in warehouses while families waited. Stakeholders called this "inventory avoidance": a rational response to an irrational system.

The accountability problem

No trail

Paper forms got lost. There was no centralized record of who last touched a device, where it was stored, or what happened after distribution. Grant auditors needed a complete chain of custody at every stage. Without it, the program was at risk.

A tool that moved fast but left gaps would fail audits.

A tool that captured everything but slowed people down would never get used.

Both problems had to be solved at once.

03 — Research & insights

We mapped the process and the people before we touched a single screen.

We could not afford to get this wrong, so we understood it first. I split the team across research tracks to move faster without losing depth, mapping the existing workflow, building out the user picture, and pressure-testing everything the brief left unanswered through kickoff meetings and working sessions with administrators, managers, and warehouse workers.

What we found

The system was more fragmented than anyone had described
  • Staff didn't always know where specific devices were
  • There was no way to answer basic audit questions in real time
  • Accountability needed to be captured at every stage:
    • shipment intake
    • first storage
    • device testing
    • relocation
    • event preparation
Every handoff was a gap that nobody had formally mapped before.
The brief had missed the user entirely
The sessions revealed something the brief hadn't accounted for: users ranged widely in technical confidence.
  • Program administrators and managers were comfortable with software
  • Some warehouse workers were not
That gap wasn't a footnote. It became the foundation for every information architecture decision that followed.
Key finding
The range of technical confidence across users was wider than expected. It forced the interface to work for both confident administrators and first-time warehouse users without adding complexity.

A constraint that shaped the platform decision

We evaluated dedicated barcode scanners against mobile camera scanning on devices staff already had.

  • no procurement
  • no extra training
  • one tool that worked in both the warehouse and at distribution events
The problem wasn't just tracking. It was trust, and a physical one.
04 — The blocker

Design took one month. Getting to design took much longer.

The project ran for eight months total, with a fixed December launch deadline. We were allocated three months for design and delivered in one. But the months before design started were not idle time. They were consumed by a problem that had nothing to do with screens.

We had eight stakeholders who couldn't hold alignment across meetings. Direction agreed on one week would get revisited the next. New features were proposed, debated, and walked back. My team couldn't design without knowing what we were designing. While we waited, we stayed productive, working on documentation, software specs, and UI guidelines, but the instability had a real cost.

The turning point

I raised the issue directly with the product manager. The churn wasn't a design problem. It was a scope problem, and it needed to be named.

Once the product manager stepped in and refocused stakeholders on the two core goals, faster shipment intake and a complete audit trail, the brief stabilized.

We narrowed v1 scope to intake and audit traceability, deferred grant-level tracking to protect the December timeline, and restricted login to LA County credentials for compliance.

Scope discipline is what made the launch possible.

Once scope was locked, I assigned sections of the app across the team and personally owned the three highest-priority flows: the homepage, the scanning screen with flagging, and the summary page. I shared design direction with the engineering lead in parallel throughout, so by the time we handed off final designs, the backend was already ahead. That is a large part of why the project shipped on time.

05 — Design question

Can someone pick this up and start scanning in under 10 seconds, without being told how?

With research complete and the brief stable, I structured early sessions around independent sketches before any group discussion, so the direction came from the full team rather than whoever spoke first.

The initial instinct was to lead with visibility. Stakeholders kept repeating that they needed to see where devices had been and where they were going, so that framing stuck. The first homepage surfaced history and laptop reports front and center. Scanning, the primary action, was tucked behind a nav icon. Starting a shipment required 4 to 6 interactions.

Before moving to high-fidelity, I ran formal usability sessions to validate workflow assumptions, not just visual choices. Hour-long paired sessions with program administrators, managers, and warehouse workers who had not seen the app before.

90%
Of participants couldn't find the scanning feature. They paused on the homepage, selected secondary actions, and eventually located the entry point, but only after significant confusion. The tool's most important action was invisible.

06 — Key decisions

Three decisions that changed how the tool and the system worked

Each decision was evaluated against the same question: can someone pick this up and start scanning immediately, without friction getting in the way? The options I didn't choose mattered as much as the ones I did.

01 Make the homepage the entry point
The problem
90% of participants couldn't find scanning. The homepage surfaced history and reports front and center. Scanning required 4–6 interactions to reach. The most frequent action in the workflow was the hardest to find.
The decision
I restructured the homepage around one prompt: "How many laptops are you scanning?" with two options, One or More. Designed to work for every level of technical confidence. The two flows also had different backend requirements, so this wasn't just a UX decision. It was a system decision.
The shift
100% of follow-up testing participants could start scanning immediately. Pre-scan interactions dropped from 4–6 down to 2. The primary function was no longer something you had to find.
Before
Old home screen
After
New homepage
02 Flag during scanning, review after
The problem
Interns scanning 50+ devices had no way to flag damaged laptops in the moment. We considered a yes/no review at the summary stage, but with shipments up to 1,000 devices, that was the same problem in a different place. The exception had to be captured in the moment, or it would get lost.
The decision
One tap during scanning flags the device. The summary page surfaces flagged items at the top automatically, separated from standard entries. Staff handle all exceptions together before submitting: no scrolling, no memory required.
The shift
Scanning flow stayed intact. Problematic devices were impossible to miss at review. Nothing fell through the cracks.

03 Solve the physical problem, not just the digital one
The problem
Every time a device moved locations, staff had to re-open the box and physically inspect it. There was no way to confirm it hadn't been tampered with between scans. No app could fix that on its own — the gap was physical before it was digital.
The decision
Two physical changes came out of the design process. First, asset tags applied to boxes by the supplier before shipment, so staff could scan without opening. Second, tamper-evident seal stickers introduced at intake: once a device was verified and repackaged, a seal went on. A broken seal made tampering visible immediately.
The shift
Staff no longer had to re-open boxes at every location change. The seal confirmed physical integrity. The scan confirmed custody. Together they fulfilled the audit requirement without adding friction to every move.

07 — Outcome & impact

From avoidance to proactive verification.

The app shipped in December 2024 and the operational change was immediate. Administrators could answer audit questions in seconds rather than hours. The tool also did something we hadn't planned for: it made the program easier to scale.

This is an internal tool. A live link is not available, but the product shipped and is actively in use by LA County.

93% Intake time reduced 2 weeks down to 1 day
↓70% Staff per shipment 8–14 interns down to 3–5
7,000+ Devices tracked 3,000+ laptops distributed since launch
Audit-ready Complete device traceability Cradle-to-grave chain of custody

An LA County manager put it best after seeing the tool: "Wow, this is amazing. I would like to see if we can adapt this for our asset tags."

— Manager, LA County

Staff who had been avoiding inventory movement started proactively verifying devices before distribution events. That behavioral shift, from avoidance to ownership, was the outcome that mattered most.

08 — What I learned

Three things I'd carry into any complex workflow project.

Research reveals what briefs miss

The brief described a tracking problem. Research revealed it was physical as much as digital, and that the user range was far wider than anyone had documented. Both discoveries changed the direction entirely.

Test the primary action first

Stakeholder input shaped the first design before a single user validated the core task. 90% of participants could not find scanning. Starting with "can someone do the one thing this is for?" would have caught that earlier.

Name the scope problem early

Stakeholder misalignment cost weeks. The fix was naming it as a scope problem, not a design problem, and bringing the PM into that conversation with a clear proposal rather than waiting for consensus.
