The principle that "the Agile BA should do enough to move on, and no more" directly relates to the DSDM (Dynamic Systems Development Method) principle of "Deliver on time." This principle emphasizes the importance of maintaining strict deadlines and delivering products within the agreed-upon timeframe. The idea is to prioritize work based on its necessity for the current iteration and ensure that the team does not spend excessive time on tasks that are not immediately essential. This approach helps in preventing scope creep and ensures that the project remains on track.

In the context of Agile, this principle aligns with the practice of iterative development, where each iteration is timeboxed, meaning it has a fixed duration. The goal is to produce a potentially shippable product increment at the end of each iteration. By doing just enough to move forward, the team ensures that they can deliver valuable functionality within each timebox, thus adhering to the principle of "Deliver on time."
