Great advice by Mark Boulton for young designers.
How can you demonstrate the value of design games, or collaborative moodboard exercises? Or that it took six months of negotiating with dozens of facets of an organisation in order for a content strategy to be adopted? My advice would be to write a story. Show photographs of workshops. Demonstrate how you approach these things. List the methods you’ve used and those that have worked. List those that haven’t and the reasons why.
