UX Process

I use an evidence-based methodology to improve the user exerience of products and processes. This Define-Evaluate framework for evaluating and improving user experience is based on the Six Sigma DMAIC methodology.

Defining metrics, users, and tasks, and measuring before and after changes helps ensure the user experience is quantifiably better.

Define your outcome measures.

The "best" metrics depend on your research goals and content. Use this chart to help choose.

Performance metrics

  • Task success

  • Time-on-task

  • Errors

  • Efficiency

  • Learnability

Issue-based metrics

Define the users and what they're trying to accomplish.

Who is the person using your product? What are they trying to do?

  1. Top-task analysis

  2. Awareness and Usefulness Gaps

  3. Self-reported metrics

Measure the baseline.

You don’t know if you’ve improved the experience unless you know where it is before changes are made. Measure first using the existing product experience with a sample of users attempting the top tasks and collect the metrics you identified.

Make your changes.

Implement your new design, feature, branding, or bug fix. Think iteratively here. It’s better to fail fast.

Measure after your redesign.

Did your changes increase the Return on Investment (ROI) of UX? By how much? Did you introduce new problems in the process?
