UI Design Task

Brief received: 28th May  |  Presentation date: 4th June

TV Product page reference

Problem Statement

  1. Interactions with add to basket have dropped year on year affecting conversion
  2. Customer feedback is that key information is difficult to find to support making a decision on whether the product & services meets their needs
  3. The total number of bundles (main product with an add on) purchased has fallen
  4. Customers feedback is that identifying similar models of television is very important to making an informed decision
Bearing in mind the current design and customer / business pain points, the brief is to complete design analysis and give recommendations. We are keen to see your process and observations.

Discovery phase


What are the problems?
Where do I start?
What do I know?
What’s the existing experience like?
What are the constraints?

Task Interpretation

UXUI Design exercise
Information design exercise
Interactions design exercise
Create Exceptional experience
Planning & Execution 

The Approach

  • Documentation
  • Understand problem statement
  • Own experience, make notes
  • Review existing journey
  • Note observations

Definition phase

Develop a clear creative brief that frames the fundamental design challenges.


What data do I have?
Who am I designing for?
What is JL’s archetypal customer?
What is the existing customer behaviours?
Which device is most popular?
How long is general dwell time and what are the hotspots?

What are the best options & solutions?
What is the most common entry point to this page?
What is the traffic on this page like and where are they from?
How much time do I have?

The Approach

  • Sizing, planning & realistic estimate including prototyping and testing
  • Persona creation, assumptions
  • Possible entry points (not essential)
  • Competitor analysis & best examples in the industry
  • Identify and consider all possibilities
  • Prioritisation
  • Feasibility  


“Interactions with add to basket have dropped”

“Difficult to find information” “Number of bundles have fallen”

“Identifying similar models of television is very important”

  1. Content-heavy, too much to look at
  2. Difficult to read & find information (esp. on mobile)
  3. The ‘Promotional Code’ section is not easy to understand
  4. The bundle is not visually engaging and hard to understand
Information Architecture
  1. When user clicks on ‘Product Description’, it anchors down below the CTA to ‘Add to basket’ and logical sequence after reading the information, user would look for CTA below it and not above
  2. ‘Product Description’, ‘Specifications’, ‘Brand info’, ‘Delivery options & Ratings’ section feels detached from the main product summary and price
  3. Upsell is distracting the flow
Section boundaries
  1. Sections boundaries are not clear. 
  2. ‘Customer also viewed’ section separates the main product summary and product info section.
  3. The bundle section is not clear – ‘Perfect partners’ and ‘Don’t forget’ section is a small part of the ‘Product Description’
  1. Due to the length of the page, there is no quick way to get back to the top
  2. Amount of scroll causes fatigue
  3. CTA to Add to Basket is not always visible
  4. When selecting an add-on, unexpected information popped up
  5. Noticed the compare function is on the product list page and there is no section to show the variant of the similar TV – size, type, other brand?

Design & Development phase

My objective is to create simple, functional and visually engaging UI that enables customer to find the information they need to make an informed decision on adding item into basket and confidence in taking on bundles and add ons.


What are my ideas/inspirations?
How will I capture these ideas?
What resources do I have?
How much time do I have to create UI Toolkit?
What’s the fastest way to achieve framework?
Which breakpoint?
How do I reduce friction?
