SAP Fiori Mobile App: Library Book Rental & Delivery

Overview

This project focusing on designing a mobile app for students to rent library books and have them delivered conveniently. I took the UX, interaction design, and visual design, ensuring an experience that is intuitive, efficient, and aligned with SAP Fiori's design principles.

The Challenge

Many students struggle to find and borrow books due to complex catalog systems, confusing nomenclatures, and bureaucratic processes in university and city libraries. The goal was to simplify the book rental experience through a mobile-first approach, making book discovery, reservation, and delivery effortless.

Hypothesis

  • Students spend too much time searching for and renting books, especially during exams.
  • Library borrowing systems are often bureaucratic and unintuitive.
  • A mobile application can simplify the rental and delivery process, reducing friction.
  • The adoption of SAP Fiori ensures a consistent and structured user interface.

Minimum Viable Product (MVP)

To prioritize features effectively, I developed an MVP matrix based on:

  • Competitive research – Identifying existing app strengths & gaps.
  • Feature prioritization – Categorizing essential vs. secondary functionalities.
  • User needs – Focusing on critical pain points.

The features in blue were also identified in the competitive apps.

The features in pink were not available in the competitive apps and would be unique for us.

Features in grey are planned for future iterations.

User Flow & Navigation

Based on the MVP matrix, I developed a sitemap, defining essential navigation paths to avoid complexity.

Low-Fidelity Wireframes (Paper Prototypes)

To quickly explore design ideas, I created paper prototypes, iterating on core screens and placement of UI components for ease of use.

Mid-Fidelity Wireframes

Mapped user interactions and transition flows between screens. Validated early iterations to streamline navigation.

High-Fidelity & Prototyping

The final UI was created in Figma, following the Design System
