My job involves a mix of UX, interaction and visual design and a bit of front end development. I'm one of two designers in my officer and lead the UI design there. Most of my work involves sketching, wireframes, user flows, brainstorming, branding, prototyping, visual designs and sometimes writing a bit of HTML & CSS.
I started out working with digital agencies so I'm used to working quick under tight deadlines and I'm definitely not slow at what I do although my visual designs definitely slow me down the most. I spend too much time thinking about colours, typography and spacing, even though the layout has been clearly defined in the wireframes it still happens regularly.
I remember reading that Zurb get their designers to start with 6-8 quick designs within 3 hours. I know this is just a quick-and-dirty way of getting the ball rolling but I'd struggled to get that done in at least a day.
I'd be interested to hear if anyone else has or had the same problem or even has ideas on how to work past this and speed up the process.
