My Role

The Problem

BigBank’s clients are struggling getting to the bank and manage things like credit cards or their own account. It takes time and frustrations to do so - nothing is online yet.

The Solution

Create a fully responsive website for BigBank’s clients. The user will login and begin manage his account by his own. He also has a live support with a banker if needed.

Research Findings

I conducted a quantitative research based on questionnaire I created about the experience with an online bank account management. I found out that almost every bank uses online services to provide fast and useful solutions to their clients. Also, people who has a full control of their online account are happier customers and secured. Although, a bank has a lot of features and options to manage, so I picked the most relevant and used day-to-day actions people do in their account.

User Persona

David is a car mechanic living in Israel and is single. He’s saving money in his bank account but he’s frustrated from going to the bank and wait for the line or call the banker to manage things in his account. David needs a platform in which he can manage his account by himself. Based on the research, I created a user persona which represents a potential user who needs a solution for this problem he's currently facing.

User Journey Map

User journey map helps us understand what is the path the user takes in order to complete a task. Also, user journey map allows us to see the flow from the user's eye and find the easiest solution for him. The goal for this user journey map is to manage a personal online bank account through a responsive website.

Paper & Digital Wireframes (Low-Fidelity Prototype)
I sketched these paper wireframes to find the best structure for the solution I am looking for. I came up with four different options and based my design on them. Moving from paper wireframes to digital ones made it easy to understand if I addressed the user’s pain points and improve the experience. I prioritized a call-to-action button to manage cards and see recent transactions right at the home page.
