Which two statements are true about the influence of batch size in the system?

The statement that proximity (co-location) enables small batch size is true because being physically close to team members and stakeholders encourages better communication, collaboration, and faster decision-making. This proximity allows teams to address issues quickly and fosters a culture of continuous feedback. As a result, teams are more likely to work in smaller batches of work, which leads to an increase in agility and responsiveness in the development process. Smaller batches enable quicker testing, validation, and delivery of features, allowing teams to obtain feedback and make necessary adjustments more efficiently.

Good infrastructure enabling large batches may imply that the systems and tools used can handle substantial workloads, but it doesn’t necessarily promote an efficient workflow or encourage agility that smaller batches provide. Additionally, while large batches can lead to project slippage, the statement regarding the severe project slippage resulting from large batches presents one side of the argument without addressing the complexity that large batches bring to coordinating, testing, and validating work, which can also cause delays. Hence, the influence of batch size in the system is significant, making the association between proximity and small batch size a strong point.
