Fare Top-Up Redesign: Getting Riders Through the Gate in 22 Seconds
*A case study by Imani Brooks-Delacroix, Senior Product Designer*
Overview
Larkspur Metro Transit moves about 140,000 riders a day across buses and light rail. Most of them pay with a reloadable card, and every one of those cards eventually runs out of money at a station kiosk or in the mobile app. I led the redesign of that moment, the top-up, from first research to launch.
The Problem
Topping up a card should take a few seconds. At Larkspur it took more than a minute, and nearly four in ten riders gave up before finishing.
• 62% of started top-ups were completed.
• 74 seconds was the median time to complete one.
• 1 in 5 support calls to the rider line was about a failed or double-charged top-up.
Tell the story of one project
The prompt
Create a Doc portfolio case study for my project Fare Top-Up Redesign at Larkspur Metro Transit, a regional bus and light-rail agency. Include an overview with role, team and timeline, the problem, research and insights, ideation, the final design, results with numbers (top-up completion up from 62% to 91%, median time to top up down from 74 to 22 seconds, fare-machine support calls down 38%), and what I learned. Story-driven and skimmable.
Make it yours
- Change the details in the prompt to fit ux & product designers.
- For example, change it so that the project is a medication-reminder app for a pharmacy chain and the results are a 34% rise in refill adherence and a 4.8 app store rating.
- Ask for edits in plain words: tone, colors, length, layout or data.
- Share the result by link or export it when you are done.

Predictive Maintenance Pilot for the Machining Floor
Prepared for: Executive Leadership Team · Prepared by: Dennis Achterberg, Plant Operations Manager · Date: May 4, 2026 · Decision needed by: May 12, 2026
Executive Summary
Unplanned machine stoppages cost Brannock Precision an estimated $704,000 in lost throughput in 2025. We propose a six-month pilot that places vibration and temperature sensors on our 12 highest-volume CNC machines and uses the data to flag failures days before they happen.
The total investment is $159,920. If the pilot cuts unplanned downtime by 30%, it recovers about $211,000 a year and pays for itself within ten months of going live. We are asking leadership to approve the budget and a June 1 start.
Background and Problem
Our 12 pilot machines produce 68% of plant revenue. Today we service them on fixed calendar schedules, which means we sometimes replace parts that are still healthy and miss failures that develop between inspections.
• 612 hours of unplanned downtime on these machines in 2025
• $1,150 per hour in lost throughput, overtime and expedited freight

Gillroot Farms: Business Plan 2026–2029
*Fresh gourmet mushrooms, grown indoors and delivered within 24 hours of harvest to the Twin Cities.*
Executive Summary
Gillroot Farms is a climate-controlled indoor mushroom farm that supplies independent restaurants, neighborhood grocers and subscription households in Minneapolis–St. Paul. Most mushrooms sold in Minnesota travel 1,500+ miles and arrive 5–8 days after harvest. We deliver in under 24 hours, with longer shelf life and specialty varieties that buyers can't reliably source today.
We are raising $850,000 to build out a 4,500 sq ft facility, reaching $1.46M in revenue and positive EBITDA by Year 3.
Company Description
Gillroot Farms is a Minnesota LLC with a leased, pre-inspected warehouse bay at 1840 Marshall Street NE. The facility has three-phase power, floor drains and a loading dock, which cuts build-out time to about 14 weeks. Our mission is to make local, peak-fresh specialty mushrooms as easy to buy as a case of onions.
Market Analysis
• Restaurants: about 410 independent full-service restaurants in the Twin Cities spend an estimated $6,000–$18,000 a year on specialty produce.

Re: Exhibit Developer, Coastal Ecosystems
Dear Dr. Halvorsen and the hiring team,
Last July I stood in your Tideline Gallery for two hours and watched a seven-year-old refuse to leave the sea star table. He wasn't being told anything. He was *noticing*: how the arms curled, why the water felt colder near the rocks, and what the empty shell meant. That is the kind of curiosity Pelican Point protects, and it is why your open Exhibit Developer role is the one I have been hoping to see. Your commitment to exhibits that visitors can touch, test and argue about, rather than read and walk past, is exactly how I learned to teach.

Offline Trail Packs
Problem statement
Cairn works well until the signal drops. In Q1 2026, 38% of support tickets (1,140 of 3,000) came from hikers whose map stopped loading mid-trail. Our current "save route" feature caches only the tiles a user has already viewed, so the map goes blank exactly where people need it most: past the trailhead, at a junction, in fog.
Competitors let users download whole regions, and 22% of churned Cairn Plus subscribers in 2025 named this gap in exit surveys.
Goals and non-goals
Goals
• Let any user download a complete region (maps, trail data, elevation profiles) in under three taps.
• Keep downloaded data fresh without manual work.
• Cut "map won't load" support tickets by at least half.
