Layering contributes to the design of a software system in several ways:

1. **Simplicity and Organization**: Layering helps in breaking down the complex system into simple, manageable layers. Each layer has its own responsibility and functionality. This makes the system more organized and easier to understand.

2. **Abstraction**: Each layer provides an abstraction for the layer above it. The higher layers do not need to know the details of the lower layers. They just need to know what services the lower layers provide. This helps in reducing the complexity of the system.

3. **Modularity and Maintainability**: Since each layer is independent of the other layers, changes in one layer do not affect the other layers. This makes the system more modular and easier to maintain.

4. **Reusability**: The layers can be reused in different systems if they provide generic services. This helps in reducing the development time and cost.

5. **Isolation of changes**: If a change is required in some functionality, only the layer providing that functionality needs to be changed. The rest of the layers remain unaffected.

6. **Security**: By separating the system into layers, we can provide security at each level. For example, we can have a security layer that handles all the security-related issues.

7. **Performance**: We can improve the performance of the system by optimizing the individual layers.

8. **Testing and Debugging**: Testing and debugging become easier as we can test individual layers separately.
