To design a new resilient interface addressing the issues of the previous application.

Transitioning cashiers to it needed to be seamless and straightforward.

</aside>

"Kassa" — is a terminal used by a cashier in a store when serving a customer. There was already an application from a third-party developer, which was poorly developed, had many technical and interface problems.

It was necessary within a year to create your own application from scratch. The task is at least: to repeat all the functionality of the current cash register, wrapping it in a normal interface, and do it so that 20 thousand of our customers do not stop sales.

Solved tasks

01

Analyze the working conditions of cashiers, the problems they face, and the tasks the cash register application should solve

02

Make the primary scenario of item intake and sales as simple, easy, and seamless as possible

03

Design the remaining scenarios and hand them off to development, ensuring accurate implementation

04

Support cashiers in transitioning to the new App

01 • Objective

Analyze the working conditions of cashiers, the problems they face, and the tasks the cash register application should solve

Steps

1. Collected and analyzed known issues with the existing application
2. Conducted interviews with cashiers and observed their working conditions
3. Analyzed device types and their technical limitations (platforms, resolutions, physical screen sizes, interaction methods)
4. Agreed on core interface principles

Outcome

Cashiers are under constant stress due to managing multiple tasks simultaneously and bearing high financial and reputational responsibility.

Repetitive tasks with the cash register become subconscious routines. Any problem that disrupts this automatic process can have serious consequences.

The cash register should not distract cashiers from their primary duties.

Processing and selling items is the most critical and frequently used scenario and must be as simple and seamless as possible to avoid distracting cashiers from their tasks.

We did research, interviewed store staff, collected issues with the current solution, and got empathy for our cashier users.

Variety platforms and devices

As a result, simple requirements for the interface were formulated:
