Personas

The team knew few about the Cadillac Escalade owners, so we started with this.

The research team offered the following personas, after some survey and user interviews. I joined most of the user interviews.

Supermom: 34, Beauty Salon Owner, 4 kids

Hipster: 40, Recording Studio owner, single

Nearly Retired: 60, Construction CEO, single

I referred to them throughout the entire product development process.

Product Scope

ContentGM offered a requirement file, listing all the features they want. I went through the list, worked with PM to offer the following feedback:

Design vs Feature: e.g. "Need to have a direction arrow for each search result" vs "Need to help users understand the direction of each search result".

De-scope: I believe that for having a feature, we need a better reason than "It won't hurt", "We always have this" or "All others are doing it".

By going through and polishing the requirements, we had not only freed up more room for designing but also understood better for customer's goals.

Happy Path

After we had agreed on the scope of features, I began to think of some happy paths. I did this first to focus on the key features, without spending too much attention on the frictions of user experience.

I reviewed and iterated on 3 different paths I came up with until the whole team has the same vision.

Then, I worked with the research team and customers to test the happy path with our target users.

The goal is to prove the mental modal in the happy path, does offer an intuitive and enjoyable user experience.

Review Process

It was really important to build trust with the stakeholders at GM so we can push the limit on the design. I spent 1 week with them to define this review process, which allows different audiences to review the design at different stages.

What we focused on:

  • Transparency: Try to include the team in the design process as early as possible.
  • Different audience: PM needs to understand the flow fast, dev needs to cover most of the logical cases, QA needs to know what had been changed.

Potential Risks

Laying out navigation on a system that used slant has some unique problem.

For example, if later in the timeline, we decide to update some angle of the slant, all the screens would need to be updated manually.

This actually happened in this project, but since we defined how to handle it already, it didn't make a mess.

Curve definition, global and specific cases for

Motion Delivery

Curve Definition

This is to spec different speeds for the animation, so the dev team can reuse them for most of the animation.

Global Cases

Those are the motion method that can be reused in multiple locations.

Specific Cases

Those are the motion for some special cases.

Clinic Findings

After we built the product, I worked with the research team to run multiple usability tests, then iteration base on them.

Not all can be accepted easily, but here are some examples.
