03ApproachMindset
What I believe about the work
- Context first: take the time, find allies who share it.
- Break it into pieces, then build something new from them.
- Plan for scale: know the size of the work ahead.
- Be an enabler: bring in people who are new to UX.
- Design on trust: show that the process makes sense.
- Open to feedback, open about what we do.
