We use user centred design methods in product development processes to create usable, valuable and successful products. We use a small set of methods over and over again because we are familiar with them and can easily ‘tweak’ them a little to our situation. But using the wrong method can lead to bad design decisions. With over 200 methods and techniques available, how do you choose what’s best? I initiated UCDtoolbox and in collaboration with the TU Delft I created a platform to solve this challenge.
