About

Caroline Jarrett

I’m the leading user experience and usability consultant specialising in forms and surveys.

I set up my business Effortmark Ltd in 1994, working on a wide variety of forms (paper and web), websites, transactions, and surveys. I’ve written extensively on  these themes and speak regularly at international conferences on design, usability, surveys and forms. See a full list of my presentations and publications.

Since 2013, I’ve mostly been working with the UK Government Digital Service. My main focus there is on design patterns for forms, which I spoke about at the SDinGOV conference.

My work in usability and design
