How can developers effectively manage and organize their designs in CakePHP projects?

Developers can effectively manage and organize their designs in CakePHP projects by following a consistent naming convention for their files and directories, using namespaces to group related classes, and utilizing CakePHP's built-in features like components, helpers, and behaviors to encapsulate reusable code.

// Example of organizing CakePHP components in a project
// app/Controller/Component/CustomComponent.php
namespace App\Controller\Component;

use Cake\Controller\Component;

class CustomComponent extends Component
{
    // Component logic here
}
