According to the PMBOK Guide, a Scrum project is an example of an adaptive or agile approach that is suitable for projects with high uncertainty, changing requirements, and fast delivery. A Scrum project delivers value incrementally through short iterations called sprints, where the team collaborates with the customer and other stakeholders to define and prioritize the product backlog, which contains the features and functionalities of the product. The team then selects a subset of the product backlog items to work on during each sprint, and delivers a potentially shippable product increment at the end of each sprint. The team also inspects and adapts the product and the process through frequent feedback loops and retrospectives. Therefore, a Scrum project suits the scenario of a new product launch with evolving requirements and flexible scope, as it allows the team to start the work based on the forecast of a similar project, but also to respond to changes and customer needs as they emerge.
