UX/UI Design Process

By Sebastian Bourges.
Based on Jeff Gothelf’s Lean UX

Why User Experience Design?

User Interface Design is complex. Achieving good user experience and appealing aesthetics requires a process that integrates many aspects of the product that are interconnected to the business that supports it. The method I use allows the participation of all stakeholders and users applying a scientific approach based on hypothesises and loops of feedback to produce a product that works for every user and the business interest as well.

In a nutshell

Users achieve more with less: It goes straight to the point. Users meet their goals and revenue generations are faster.
Software companies significantly reduce costs: Products are easier to sell, develop and maintain. Expansion through customer satisfaction rather than marketing pressure.

2) Interview with Users
Identify and interview each of the personas (users) defined in the LeanUX grid. Create assumptions, goals and benchmarks per user.

Recommended to interview people in their own work environments/situations.

Estimated time: 1.5hs per user.
3) Low level mockups from users
Quick draft designs and validation through feedback. Group session with selected personas.

Estimated time: average 2 to 4 hs group session.
4) Design Stage
Analysis of collected information after interviews and group mockup sessions.

Drafting stage.

Estimated time: average 5 days
5) Medium Level Mock ups presentation
Basic Interactive Mockups. Run user test with mockup and test benchmarks against assumptions.

If test fails, re-iterate design stage (4)

Design Process: average 5 days (depending on complexity) For big complex systems it can take up to 15 days and multiple iterations with client.

Estimated time per user test: average: 1.5 hs per user.
6) Final Design
Definition of styles based on Marketing and client requirements. High quality design presentation.

Estimated time: average 5 days
7) Optionals
1. Multiple Iterations of high level designs
2. High Level UX Mockups
3. UX Video Demo
4. HTML/CSS template for web applications
Estimated time: for each item, no less than 1 week.
