This week we start a 2-part series discussing overcoming behaviour barriers in design. We'll cover the tools this week before moving on to look at the business in practice in next week's Newsline. People are creatures of habit and this can introduce challenges should you want them to adopt a new behaviour. We all start forming and evolving our behaviours from the time we are born, and each of us will respond to different stimuli in our own unique way. Some of us can't start their day without our morning coffee whereas others will reach for a cigarette as a first port of call. Some can't fall asleep without a book in their hands and others like to leave their TV switched on. These behavioural differences are a big part of what makes us human. As researchers and designers, we invest a lot of time and energy in helping businesses humanise their tools, services, systems, and processes. We do this so that these things are both useful to people and usable.
