What is the purpose of a Preliminary System Design Review (PSDR)?

The purpose of a Preliminary System Design Review (PSDR) is to evaluate the system design against specified requirements before implementation begins. This step is crucial because it allows teams to assess whether the proposed design meets all the functional, technical, and performance criteria set forth in the project requirements. By conducting a thorough review at this early stage, any potential issues or deficiencies in the design can be identified and addressed before significant resources are committed to development or implementation. This proactive approach helps to ensure that the final system aligns with the users' needs and expectations, reducing the likelihood of costly changes or rework later in the project lifecycle.

In contrast, finalizing the budget is typically a separate phase in the project planning that occurs prior to or parallel to the design review, rather than as a purpose of the PSDR itself. Training users relates to implementation and support phases, which occur after the design has been finalized. Presenting the project to stakeholders has its own significance but is not the main focus of the PSDR, which is specifically about assessing design readiness.
