—Led design on future feature development updates and releases.
Scope & Constraints

—Design needed to leverage the user’s existing experiences and knowledge of the client’s legacy brick-and-mortar point of sale system without adopting its UX pitfalls.
—Features and scope creep were constant due to shifting priorities and focus in the client’s organization with minimal to no variation to the timeline. After review of existing solutions
—Small target device (iPod touch—320x568) for a robust list application.No time or budget for user research, though some key user challenges served as torches for the project.

Users and Audience
With stores throughout the Midwest, Blain’s Farm and Fleet supports rural and urban markets with product categories that overlap home improvement stores, garden centers, outdoor recreation, farm supply, and pet stores. Blain's cashiers and warehouse employees are the primary app users with Blain's in-person customers as the secondary users.
With a unique client relationship that straddled the line of external and internal consultant, this new initiative required a short but silo-ed design discovery to give internal teams a visual foundation to support their budget discussions and decisions. With minimal investment, these design-bubble flow documents and wireframes are often discarded or modified beyond recognition, but surprisingly, with the exception of feature additions, the first mPOS wireframes and flows still feel like a young, naive version of the living application. As the features grew, the order list and checkout evolved and user flows were optimized to keep it simple with progressive disclosure of advanced functions and alternate paths.

Outcomes and lessons
* With the events of 2020 the mPOs should have been poised for sweeping adoption, but some store locations have left their devices on the shelf. With a more coordinated effort, and larger budget, some internal incentive could have been created for embracing the new application.
* My future ambition for the project would be a more comprehensive effort and exploration into the UX of the application in the field. The difficulties of a small device, encased in a thicker barcode scanner, each with a battery source, and the inclusion of two additional peripheral devices seems cumbersome at best. I may be dating myself or outing my off taste in movies, but this is the image that comes to mind when I envision mPOS in the field https://j.gifs.com/910Z4x.gif
Feature: Onboarding setup flow
The product demanded a supported set-up process to assist store managers and leaders when setting up new mPOs devices, or when upgrading. With three additional devices integrated into the mPOS product, the setup is very linear and moves through each of the devices after an initial manager login.

FEATURE: Product Catalog
The mPOS was a new product with many new features for the client and their stores, but we wanted to integrate a limited product catalog borrowed from their public mobile ecommerce app. Featuring category navigation, a product list, and a simple product detail page. Employees are empowered to assist customers looking for a visual of a product, product details, or assist customers with payment for self service products.

FEATURE: Scanning Device Sled
