Implementation of the Design Thinking Method in the UI/UX Development of a Mobile Application for Flower Bouquet Customization

Flower bouquet ordering often requires customers to communicate multiple customization details, including flower types and quantities, wrapping materials, greeting cards, previews, and estimated prices, which may cause uncertainty and inefficient communication. This study aimed to develop and evaluate the user interface and user experience (UI/UX) of BloomCraft, a mobile application for flower bouquet customization, using the Design Thinking approach. The research followed five stages: Empathize, Define, Ideate, Prototype, and Test. A preliminary Google Forms survey yielded 50 eligible responses from participants with bouquet-purchasing experience. The findings were used to define user needs and generate design solutions, while a high-fidelity interactive prototype was developed in Figma. The prototype was subsequently evaluated by 11 participants through seven task-based scenarios, ten five-point Likert-scale statements, three overall evaluation questions, and open-ended feedback. All participants reported completing the seven tasks, resulting in a task completion rate of 100%; 68 of 77 task executions (88.3%) were completed without difficulty, and nine (11.7%) were completed with difficulty. The prototype achieved an overall mean score of 4.77 out of 5, with 106 of 110 responses (96.4%) categorized as positive. These results indicate that BloomCraft's main customization features were understandable and supported users in selecting bouquet components, viewing previews, identifying estimated prices, and reviewing order details. The study concludes that Design Thinking can support a user-centered bouquet customization prototype, although evaluation with a larger and more diverse user group on an implemented mobile application is recommended.
