Introduction
Effective communication is a cornerstone of successful projects, and functional design specification significantly enhances this process. It acts as a shared reference for all team members, ensuring everyone is aligned on system expectations.

Communication Benefits
By clearly outlining features, workflows, and business rules, FDS reduces misunderstandings between developers, stakeholders, and testers. Visual aids such as use case diagrams and workflow charts help convey complex interactions in an accessible format. Regular review sessions based on the FDS allow teams to discuss changes, clarify doubts, and maintain alignment throughout the project lifecycle. This structured communication ultimately contributes to smoother development, fewer revisions, and higher-quality deliverables.

Conclusion
Functional design specification strengthens communication across teams, creating a collaborative environment where expectations are clear and project goals are consistently understood.
