In a meeting, your managing director passes out a copy of the Agile Manifesto. They said that agile teams are better at developing software. So you should read the printout and then work together as an agile team. What's one of the challenges with this approach?

a) The Scrum Master should be the one who distributes the manifesto

b) There wasn't a customer in the room to collaborate on the product

c) It's clear that the managing director will never give up upfront planning

d) The Agile Manifesto describes a mindset and not a practical way of working
