Agile project management emphasizes iterative development, with each sprint producing a potentially shippable increment, and includes cross-functional teams who collaborate closely with stakeholders in a process that allows for adjustments as requirements evolve and formalizes feedback loops at the end of each sprint.

*People and their interactions rather than procedures and equipment.

*Functional software as opposed to extensive documentation.

*Client cooperation as opposed to contract drafting.

*Adapting to change as opposed to sticking to a plan.

UMLs are a big part. I like using Excalidraw for UMLs.
