Hackathons are an excellent way of helping colleagues think up great ideas to solve problems (or 'make things better') and this episode takes you behind the scenes at the 2015 Retail Week House of Fraser Hackathon in association with Infosys. I designed the methodology behind this hackathon, so in this episode I explore how I have changed the way that hackathons are judged and scored to make them more interesting for all involved - and it puts the judges to work too!This episode includes behind-the-scenes audio and interviews of the judges and hackers, recorded by the excellent Retail Week Hackathon organising team of which I was a proud member.
