My earliest design challenge was thinking through how availability and fulfillment information manifested itself in more relevant places throughout the product detail page. Below are some early sketches I created to showcase the UX strategy of how we could expand the scope of availability and fulfillment information in the iPhone buy-flow.

Sticky bar. A reflection of price and fulfillment details as a customer configures their device.

Summary box. A detailed breakdown of the customer’s selections and fulfillment info.
After getting alignment from the team, my next step was to explore each component in more detail. Unfortunately, due to limited engineering resources, we had to keep the existing summary box design as is to ensure we were able to meet the project’s deadline.
In preparation for our team workshop, I took the next few days to dive deeply into the sticky bar, exploring how the content flexes at each step for desktop and mobile. The approach here was to provide relevant information at a glance, allowing customers to view more fulfillment options and edit their delivery or pickup location.

Overall, the workshop went well. My initial direction was on the right track. However, that’s not to say I didn’t get any feedback. We’ll cover a few of the key challenges for the sticky bar in a bit.

Key challenge #1
How might we highlight more fulfillment options?
A critical element of the sticky bar was communicating Apple’s competitive fulfillment options at a glance. The trickiest part of this challenge was finding creative ways to balance the content in such a tight space.
Option 1: Contextual sub-text
Option 1.1: Contextual links
Option 2: Exposing multiple delivery options
Key challenge #2
How might we provide relief in moments of tension?
Providing relief in moments of tension meant we needed to elevate Apple’s Shop by Availability tool. In the SbA tool, customers could explore similar iPhone options available sooner.
The stickiest part of this challenge was determining the right level of prominence for the SbA tool and finding a way to integrate it into the sticky bar.
Key challenge #3
How might we communicate updates to the customer?
Referring to the data gathered earlier in the project, we knew that keeping customers informed of availability and fulfillment updates influenced their shopping choices.
The thorniest part of this challenge was exploring ways to communicate changes without the sticky bar becoming too much of a distraction for the customer.
I took inspiration from sports to help influence my approach to this challenge. I paid close attention to how they kept you informed of the score without distracting you too much from the game itself.
Key challenge #4
How might we optimize the sticky bar on mobile?
More than half of iPhone customers shop from their mobile devices. With this in mind, mobile shouldn't feel like an afterthought, so I designed both desktop and mobile in tandem.
The biggest part of this challenge was finding the best way to display availability information on smaller screens without the sticky bar becoming too intrusive to the buying experience.
