By starting with a high-level view, top-down design produces documentation that is accessible not only to programmers but also to project managers, stakeholders, and clients. The hierarchical decomposition serves as a natural blueprint, making it easier to discuss requirements and identify missing features early.

Moreover, top-down thinking remains invaluable during system architecture design, when defining APIs, and when creating test plans. It also complements bottom-up strategies: experienced developers often use top-down reasoning to plan interfaces while simultaneously using bottom-up development for performance-critical or well-understood libraries.

Another challenge is the difficulty of creating accurate stubs for testing. If the stubs do not realistically simulate the behavior of unimplemented modules, integration problems may only surface late in the process. If the stubs do not realistically simulate the
