When MyProtein became a marketplace, someone had to figure it out.
MyProtein was expanding from a single-brand store into a full marketplace. The existing checkout supported one delivery option per order. I took on both PM and UX, defined the scope, designed the flow, validated it with users, and shipped it signed-off for development.

Overview
The marketplace expansion meant customers could buy items from multiple vendors in one basket, each with different delivery options, timelines and costs. The existing checkout barely supported one delivery option. The project had no PM. Rather than wait, I took ownership of both PM and UX: wrote the V1 scope, worked with engineering on feasibility, designed and tested the flow, and shipped it in under a month.
Challenge
01
The problem
Support 4+ delivery groups in a single checkout, completely new territory for the existing architecture.
02
The complexity
- Different delivery options for different vendor groups
- Order summary with split deliveries and separate pricing
- Users needing to understand why items were grouped
- Avoiding overwhelming the user with logistics
03
The gap
No PM assigned. I took on both roles, wrote the V1 scope through 5 iterations, defined EPICs and user stories, and drove the project through Q4 Big Room Planning.
What I did
- 01/ 05
Wrote the V1 scope through 5 iterations to define EPICs, user stories and technical requirements. Got it signed off at Q4 Big Room Planning.
- 02/ 05
Designed the split delivery flow, grouping items by vendor with separate delivery selections per group ("Delivery 1 of 4 (5 items), Delivered by MyProtein").
- 03/ 05
Created Named Day Delivery as a clean list rather than a calendar, specific dates with clear pricing at a glance.
- 04/ 05
Designed the order summary with split delivery pricing, transparency over compactness.
- 05/ 05
Ran usability testing with 5 participants through PlaybookUX before committing engineering investment.
Outcome
Named Day Delivery validated
All 5 participants approved unanimously: "Beautiful UI for Named Day Delivery, this is nice, this is very clear."
Split basket needs clearer labelling
All 5 understood why items were split, but the notation needed clearer vendor labels, a scoped iteration identified through testing, before engineering investment.
Signed off for development
The V1 scope was officially approved at Q4 Big Room Planning and the project greenlit for engineering.
