What is one major focus of the Sitecore Helix methodology?

The major focus of the Sitecore Helix methodology is to reduce dependencies between modules. Helix promotes a modular architecture approach that allows for independent and reusable components. By minimizing dependencies, developers can work on different modules simultaneously, resulting in a more efficient development process. This independence enhances the maintainability of the codebase, enabling easier updates and modifications without the risk of impacting other parts of the system. It also fosters better collaboration among developers, as each module can be developed and tested in isolation before integration. This aspect is crucial in modern software development practices where agility and flexibility are highly valued.

The other options do not align with the core principles of the Helix methodology. Creating a high volume of templates may prioritize speed over the strategic organization and reusability encouraged by Helix. Encouraging non-modular systems contradicts the very essence of what Helix stands for, and while standardizing visual design elements can be beneficial, it is not a central focus of the Helix methodology.
