PSD case studies
PSD · Put your knowledge to work in context.
The Professional Scrum Developer (PSD) is a Scrum.org certification described on Scrum.org as demonstrating "Knowledge of practices and techniques that support building software with Scrum." It is aimed at people who build the product - programmers, testers, designers, and other team members working as Developers in Scrum - rather than at Scrum Masters or Product Owners. The assessment is grouped around four areas: Scrum theory and framework applied to software development; development practices and techniques that support building software with Scrum; cross-functional, self-managing team collaboration and the accountabilities of Developers; and delivering a potentially releasable Increment each Sprint. The PSD case studies are 5 cases and about 3,888 words.
