Andy Murray, Executive Director of the Major Projects Association, is on location at the Projects Data Hackathon in October 2021. He records his impression of the two-day live event and explores what a data hackathon sounds like and what it means in terms of the productivity, value and success of major projects. Along the way, he chats to the founder of the Project Data Hackathon, Martin Paver, along with a number of those who have set challenges, as well as the hackers themselves.
