What is the main focus of the agile methodology?

The main focus of agile methodology is indeed on speed and flexibility of development. This approach emphasizes iterative progress, allowing teams to adapt quickly to changes in requirements or feedback throughout the software development process. By working in short cycles called sprints, agile teams can deliver incremental improvements and provide working software earlier in the development cycle. This not only enhances the ability to respond to customer needs but also encourages collaboration and continuous improvement among team members.

The agile methodology values individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan. This flexibility and emphasis on iterative development significantly enhance the overall productivity and adaptability of teams.

Other options do not align with the core principles of agile. While security is important in software development, it is not the primary focus of agile. In terms of maximizing advertisement revenue and eliminating all bugs before release, these aspects are not central to agile philosophy, which understands that not all bugs can be eliminated prior to release and promotes a more dynamic approach to feature rollout and customer interaction.
