What is the underlying ethos of DSDM's approach and style?

The underlying ethos of DSDM (Dynamic Systems Development Method) is rooted in pragmatism. This approach emphasizes delivering business value quickly and efficiently by focusing on what is most important to the project. Pragmatism in DSDM means that teams are encouraged to make decisions based on practical considerations rather than rigid adherence to rules or processes. This allows them to adapt and respond to changing project needs, ensuring that the outcomes align with the business objectives.

This ethos supports iterative development and encourages active stakeholder involvement, promoting transparency and clarity throughout the project lifecycle. Teams are motivated to find workable solutions that address real-world issues, with an emphasis on flexibility and adaptability rather than just following theoretical ideals.

In contrast, while the other options do reflect important aspects of DSDM, they do not capture the fundamental guiding principle as effectively as pragmatism. Realism, flexible requirements, and timeboxing are supporting practices within DSDM, but they stem from the more overarching pragmatic approach that prioritizes value and effectiveness.
