PROJECTS
TempTale App Usability Testing
Images modified from https://device.report/manual/7560871 and Google Play
Purpose
Customers in the life sciences were moving away from USB downloads due to security concerns. Bluetooth technology is considered a more secure alternative. In this study we tested the TempTale app which allowed for Bluetooth downloads from Sensitech temperature loggers to a Bluetooth enabled mobile device.
Team
Collaborated with life sciences product marketing and consultants.
Contributions
Recruited participants, reviewed user scripts, note taker during the user sessions, giving feedback on the direction of the study
Challenges
Our goal was 15 user studies (5 participants from each user segments--shippers, delivery drivers, and receivers). Due to recruitment challenges, only 9 user studies were conducted.
Result
Software Engineering received feedback that positively impacted the designs and implementation of the TempTale app that is currently in the App Store and Google Play.
TempTale GEO X LCD Redesign

Purpose
Design an LCD that is in line with other branded equipment and replaces the LED blink pattern user interface. Previous user testing showed that LEDs were not enough to indicate device operation. An LCD removed the need to remember and interpret LED blink patterns boosting usability.
Team
Collaborated with hardware engineering.
Contributions
Performed an internal LCD design audit. Completed a competitive analysis highlighting the strength and weaknesses of data loggers and real-time monitors with LCDs. Produced flow diagrams showing the LCD for corresponding button pushes. Prototypes animating the interplay between the LCD the app.
Challenges
The initial deadlines were very aggressive, which allowed for fewer than five business days to complete the work. There was a lack of consensus on the feasibility of introducing a new LCD.

Reefer Gateway Installation Field Study

Purpose
A major food distributor in North America is working to increase compliance among its sites by tracking location and collecting reefer temperature data for at least 10% of its fleet. Hardware engineering and design wanted to understand the head winds for installation, operation, and maintenance. I traveled to an early adopter customer distribution center and observed installation of location/temperature monitoring equipment in reefers and vehicles to document process.
Team
Collaborated with field service representative manager, sales manager, and customer success manager.
Contributions
I learned to install equipment and discovered pain points. I documented the installations with pictures and videos to present installation alternatives. The working knowledge held in sales was shared across software engineering, hardware engineering, product marketing, and product management.
Challenges
The inital installation process was time consuming and required drilling through metal plates surround the power module of reefers. Customers had limited FTEs, face worker shortages due to illness and strikes. The alternative instations were faster but could compromise weatherized connections protecting power leads.
Result
Conversations between hardware engineering and customer maintenance staff led to a more efficient installation process.
