Discovery

Introduction

The Oishii project emerges as a response to the challenge of food waste, aiming to provide an effective digital solution to tackle this common issue.

In Spain, in 2023:

Investigation

We use the Double Diamond methodology, which allows us to generate user-centered solutions. We started with in-depth research, conducting 120 surveys and 18 interviews to understand the challenges and needs of end consumers. This helped us identify key patterns, such as lack of time, difficulty in planning and calculating appropriate portions.

We decided to focus the project on end consumers, as we found a strong and accessible pain point in this group.

Survey results:

Patterns detected with the interviews:

INTERPRETATION

Users

The analysis of the collected data allowed us to identify two main user archetypes: Sofía, a hardworking individual who values efficient planning, and Marc, a more carefree young man who is still concerned about his finances.

Data Interpretation

Both share common challenges, such as lack of time, financial concerns, difficulty in organizing, and food waste. We used tools like the Customer Journey Map to better understand their needs and frustrations.

marc

Student

"I prefer to dedicate my time to studying and other interests, as cooking is neither my strength nor my priority."

Sofía

Worker

"I try to save time with each planned step, focusing on optimizing what truly matters to me."

Ideation

Solution generation

Based on the insights gathered, we generated 344 ideas, which were narrowed down to 11 finalists using a prioritization matrix. Two of these ideas underwent Design Sprints for validation: the first was discarded, while the second successfully validated the final solution. This led to the creation of Oishii, the most effective and viable solution to address our users' needs.

Selected proposal

Oishii, an AI-powered application that offers personalized recipes, meal planning, and expert tips to reduce food waste, was identified as the most effective and viable solution.

Iteration & Experimentation

Visual identity

We reflected the values of closeness, friendliness, and warmth through a color palette featuring orange, associated with food and appetite stimulation, and green, representing freshness. We chose the Work Sans typeface for its readability and versatility. Oishii’s illustration is designed as a virtual kitchen companion.

Development & testing

We developed Oishii following a backlog structured into 7 sprints, introducing an MVP in the second sprint to deliver value quickly. The prototype was iterated based on usability testing feedback, refining navigation and adding new features.

We implemented a smart chat to plan meals, search for recipes, and get expert tips, and we created a landing page to attract users.

Results & Future Perspectives

Conclusions

Oishii has proven to be an effective and valuable solution for reducing food waste, successfully addressing user needs. Usability test results confirmed that the app optimizes cooking time and reduces waste by offering personalized meal planning and AI-based recommendations.

Next steps

As a digital product, Oishii will never be truly finished—only when time or funding runs out. We will continue to iterate and uncover new insights to enhance the app. Future iterations will be based on patterns identified in usability tests and user stories from the backlog.

As the product evolves, we will explore potential partnerships with brands to expand our reach and functionality.
