This case study focuses on designing Dairy Drop, a flexible subscription-based milk delivery service aimed at busy millennials and Gen-Z consumers. The primary challenge was to create a flexible subscription feature that allows users to easily select their preferred milk and have it delivered to their doorstep. Utilizing the double diamond methodology—Discover, Define, Develop, and Deliver—the project culminated in a user-friendly, visually appealing mobile app with robust e-commerce capabilities and an intuitive milk subscription feature.

Dairy Drop is a subscription-based service that delivers organic, ethically sourced dairy and non-dairy products directly to consumers. Their goal is to serve their customers with a subscription-based dairy (and non-dairy) delivery service that allows customers to receive regular deliveries of selected products.

How can Dairy Drop provide a convenient solution for busy customers?
Time-consuming grocery trips and finding preferred dairy products can be challenging. With inefficient delivery services for specific products and limited subscription options for recurring grocery items, there's a clear gap in the market to overcome these barriers and provide a seamless customer experience.
The solution for Dairy Drop is a mobile app that provides a convenient way for their customers to receive their dairy and non-dairy products.
The app streamlines ordering, delivery, and subscription management, addressing the challenges of time-consuming shopping and inefficient delivery processes while streamling the cutomer experience.
The Double Diamond is a design process model that consists of the Discover, Define, Develop and Deliver phases. This model is widely used in design thinking to ensure a user-centered approach.

In this phase, a competitive analysis involves similar products in the market to help understand the competitive landscape. My colleagues and I identified four key players Mr.Dairy, The Organic Box, Fairlife and Mama Earth.
A comparative matrix is used to compare competitor features side by side and analyze how they can be improved.
In the Define phase, qualitative and quantitative research, user personas and empathy maps help understand the user's needs and perspectives.
A qualitative persona is developed based on non-numerical data. This is the primary research method used which involved user interviews and observations to validate assumptions.
A quantitive persona is created using numerical data like statistics and other measurable attributes. This data-driven persona is used as secondary research.
I used the quantitative data to guide an empathy map to ensure it reflects broader user behaviour rather than just a few individual experiences.
Where the defined user needs and research insights are developed into a tangible design solution.
Building on insights from the Discover and Define phases, I analyzed the competitor and user needs to prioritize features and establish a clear hierarchy for the information architecture.
During the interview with Millie, I observed that she immediately explores all options available on the bottom menu of the test prototype. In the validated user flow below I ensured that users are always guided back to their objective of ordering milk.
User Task: Subscribe to have skim milk delivered on a weekly basis.
During the low fidelity wireframe sketching phase, I explored several design concepts and narrowed it down to two. These were then used for A/B testing.
7/7 Testers Preferred option B!
