At big organizations I’ve worked in such as Nokia and the BBC, product development and interaction design are often separated disciplines, project stages and considerations.

At a start-up, they rarely are- time and resources being of the essence. Interaction Design is bound-up with actually building the thing, which has many upsides and many downsides.

I’ll be contrasting my experience of building Dopplr, a service for frequent travelers to that of design development of larger scale projects for lessons learned from both that I hope will benefit those working in both professional contexts.
