MiList - It's not a success story

MiList - It's not a success story

When real-world use exposes decisions the prototype does not reveal

01 - About

About the project

About the project

1

Context

Created from a real need: to see spending clearly before reaching the checkout. The project brought together my work as a UX Designer and that of a developer/stakeholder, serving as a practical exercise in building a product for real-world use.

Problem

Users are not clear about how much they are spending during the purchase, or about the variation in prices between markets, which leads to less conscious decisions and frustration at checkout.

Challenge

I opted for a gradual evolution strategy, distinguishing real usability problems from learned behaviours, with strong technical alignment and continuous validation with experienced users.

02 - Decisions

Key Design Decisions

Key Design Decisions

Functional flows, but not very refined
Functional flows, but not very refined

The main interactions worked, but were not deeply optimised for repeated use.

Impact

Small frictions accumulated over daily use.

High-effort search and editing
High-effort search and editing

Product search required manually deleting the text, there was no editing of the name after creation, and simple support actions were missing.

Impact

Frequent tasks have become more tiring than they should be.

Interactions that are not very tolerant of the real-world context
Interactions that are not very tolerant of the real-world context

Small click areas and the absence of batch actions required excessive precision for an on-the-go use case.

Impact

The experience did not keep pace with the user’s real-world pace in the market.

Lack of clarity regarding states and actions
Lack of clarity regarding states and actions

Actions such as deleting items or understanding whether a list was complete were not obvious.

Impact

It increased the cognitive load and the need for “discovery” through trial and error.

03 - Context

Critical Reflection

Critical Reflection

This project made it clear, in practice, that seemingly small decisions have a major impact on frequently used products. At times, I prioritised rapid delivery and technical feasibility at the expense of greater refinement of the usage context.

Having the product in production was essential to reveal these flaws — insights that would hardly emerge from prototypes or one-off tests alone.

04 - Impact

Why this case matters

Why this case matters

Although it is not a traditional “success case”, MiList represents a milestone in professional growth. It demonstrates my ability to:

  • Analyse critically my own decisions

  • Recognise real usability flaws

  • Transform continuous use into applied learning

05 - Results

Learnings

Learnings

These learnings went on to directly influence my work on subsequent projects, especially in paying attention to details, states and recurring actions.

Micro-interactions matter as much as main flows

Real-world use reveals hidden problems in early stages

Interaction scalability is essential in repetitive tasks
