Grocery App

A new product & monetization fit

Stuck on Discounts

Grocery App (real name hidden) was a direct-to-consumer e-commerce brand by a large Korean company well known for their nationwide chain of convenience stores. They were late to enter the competitive online grocery space and struggled with customer retention and monetization, as the business relied on discount deals to attract customers in the absence of a clear value proposition and a lack of model-product fit.

GROCERY APP 2.0

I led the project on behalf of Daylight Design, a premium consultancy founded by ex-IDEO leadership. The original RFP was just for UX redesign. However, after discussing the client’s business objectives with their executives, we agreed to expand the scope to redefine the service from the ground up — i.e., new Product-Market Fit (PMF) narrative discovery, hypothesis testing, mobile app product design, and execution proposals.

A New Product Fit

The Four Fits Framework is used to create & examine startup strategies. In order to build a scaleble business, we need to think about these four components, and how all of these pieces fit together.

My team focused on re-defining the product to address these two fits in particular:

  1. Product-Market Fit: A verbal narrative and a set of visual artifacts that illustrate a new product hypothesis that aims to satisfy specific use cases of a currently underserved but scalable target market segments.
  2. Model-Product Fit: Proposals to align the monetization model’s friction level and value metrics with the product’s new core value proposition.

Qualitative Research

We started by conducting customer interviews, chatting with the internal executives, visiting the warehouse, secondary research, as well as a CX audit of the current app.

Extreme Customer: High sensitivity to quality, with high purchasing power and household staff
Warehouse Tour: Ground operations, automations, difficulties, shipping time slots
Extreme Customer: Time-constrained, minimal cooking, outsource and delegate
Internal Executive: Long-time expert on delivery, shipping, and logistics with a strong POV on “freshness”
Customer: Spends $500+ per month on grocery  apps
Extreme Customer: Early adopter to new vertical apps
CX Audit: Hands-on experience and evaluation of the signup & purchasing process
Internal Executive: Strategic needs for integrating offline store delivery and quick commerce
Customer: Uses multiple auto-shipping features
Customer: Hops between 20+ apps to buy food, depending on the needs and benefits

Sacrificial Concepts

As with any product strategy project, there were controversial, vague, and high-risk questions pertaining to what Grocery App 2.0 should be like.

These questions were grouped into themes, which were then mapped to 5-10 exaggerated app concepts.

We used the extreme versions of concept mockups during our customer interviews to facilitate customer reactions and accelerate our learning.

Research Insights

Qualitative research findings indicated the main customer problem to solve is deciding what to eat for the upcoming meals in the next 24 hours, and suggesting products that will act as components of those menus.

That meant our inventory had to be overhauled to support the menu-based use cases based on the time of the day.

Inventory Overhaul

We conducted an audit of the overall product categories and major product search terms to identify a set of guidelines for overhauling the product inventory. This new inventory strategy became the foundational premise to the rest of the product fit hypthesis.

Multi-Variate Concept Validation

After we identified a rough direction for the new product, we ran broad validation sprints to de-risk the overall concept direction and learn more about target customer’s preferences on the major variables.

In order to test multiple variables at once, I devised an approach to methodically encode our assumptions into App Store design mockups and then decode them so that we can analyze the responses both qualitatively and quantitatively.

Core Habit Loop

New product strategy often leads to difficulty in getting users establish a habit around the new value proposition — a foundational requirement for retention and growth.

To help users establish a new habit loop, we arrived at the following activation trategies:

  1. Offer impressive welcome deals for new customers that consist of multi-item bundles.
  2. Bundle individual grocery items based on menu suggestions throughout the app, and make it easy to add the whole bundle to the cart.
  3. Enhance the habit loop with manufactured triggers such as daily new menu ideas and discount roulette notifications.

Model-Product Fit

The friction level of the monetization model needs to match how the value prop is experienced by the customer.

In order to lower the pricing friction and increase the Model-Product Fit, we devised a pricing scheme to offer small discounts (3% or more) when you buy any of the items listed in the menu-based bundles.
