Reduce software complexity during code reviews by applying a structured framework that evaluates module depth, information hiding, and naming to identify hidden dependencies and propose refactors for simpler interfaces.

The best way to design deep modules for API architecture involves applying principles like pulling complexity downward and defining errors out of existence to achieve simpler, more robust interfaces with strong information hiding.

Information hiding improves module decomposition by encapsulating implementation details within deep modules, which reduces system-wide complexity and prevents hidden dependencies from leaking into external interfaces.

Yes, you can use John Ousterhout's design philosophy for refactoring existing projects by evaluating current module interfaces, pulling complexity downward, and redefining errors to achieve cleaner, more modular architectures.

You need structured software design guidance for architecture discussions when evaluating module decomposition, API design, or refactoring scenarios to systematically reduce complexity and make better modularity decisions.

Shallow module architecture increases code complexity because it exposes implementation details and fails to hide information effectively, leading to hidden dependencies and interfaces that require extensive manual error handling.
