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.

From 2013 to 2016, I worked mostly with the UK Government Digital Service (GDS). My main focus there was on design patterns for forms, which I spoke about at the SDinGOV conference. My work helped GDS to create the GOV.UK Design System, released as a public beta in June 2018.

After taking a year off to have successful treatment for leukaemia, I am now gradually returning to consultancy on design systems and design that’s relevant to forms: service design, content design, interaction design, and user research with designers and with people who use forms. My main focus at the moment is NHS Digital, mostly providing advice to their team working on the NHS Service Manual.

My work in usability and design

For the 2014 UXPA (User Experience Professionals’ Association) Conference I was interviewed about surveys and forms design – and why I do it.
