What does the high-level design (HLD) document during Inception focus on?

The high-level design (HLD) document during the Inception phase focuses on providing a broad overview of the system architecture and its components. It is primarily concerned with how different systems will interact with each other, which is what integrations encompass. This includes specifying how various parts of the application will communicate, the data flow between systems, and identifying external interfaces.

By detailing integrations, the HLD sets the foundation for more technical specifications that will follow in later phases. This is crucial for aligning stakeholders on the architecture vision and ensuring that the design accommodates all necessary connections to fulfill the project requirements effectively.

While team responsibilities, budgeting, and user experience are all important aspects of project planning, they do not specifically align with the primary objective of the high-level design document, which is to map out the integrative aspects of the system’s architecture.
