Review a Recurring Grocery Order
Design a weekly grocery routine that lets a household confirm quantities, substitution rules, budget, and delivery timing.
The brief
Understand the problem
Background
A recurring grocery basket saves planning time, but food needs and inventory change every week. Substitutions can affect diet, quantity, recipe plans, and final price.
User context
The Rahman household receives groceries every Sunday. This week two people are away, and one child has recently developed a dairy allergy.
Product problem
The service must automate familiar choices while requiring careful review of changed household needs, unavailable items, and sensitive substitution preferences.
Objective
Create the review, edit, substitution, and delivery flow for a recurring household grocery order.
What to design
Define the experience
Required experience
- Upcoming basket grouped by household need
- Fast quantity and skip editing
- Item-specific substitution rules
- Final total and delivery review
- Shopper communication during fulfillment
Screens and states
- Upcoming basket
- Basket editor
- Substitution settings
- Checkout review
- Shopper updates
Core user flow
Follow the critical path
- 01
A parent reviews the suggested weekly basket
- 02
They reduce quantities and update the household allergy profile
- 03
They set stricter substitution rules for dairy-related items
- 04
They confirm the delivery window and estimated total
- 05
During shopping, they approve one replacement and reject another
Product rules
Requirements and constraints
Requirements
- Distinguish recurring staples from one-time items
- Show how household-size changes affect suggested quantities
- Keep allergy information prominent in substitution decisions
- Support replace, refund, contact me, and no-substitution rules
- Explain why the final total can differ from the estimate
- Preserve a time-limited shopper communication record
Constraints
- Inventory is confirmed only during picking
- Weighted items have variable final prices
- The customer may not respond while the shopper is in store
- Food safety and allergy information cannot rely on color alone
Reality check
States worth considering
Finish line
What to deliver
- Create five mobile screens that cover basket review, allergy-aware substitutions, checkout, and live fulfillment.
