A preliminary design review (PDR) is

[a] multi-disciplined technical review to ensure that a system is ready to proceed into detailed design and can meet stated performance requirements within cost (program budget), schedule (program schedule), risk, and other system constraints. Generally, this review assesses the system preliminary design as captured in performance specifications for each configuration item (CI) in the system (allocated baseline), and ensures that each function in the functional baseline has been allocated to one or more system CIs. Normally conducted during the Technology Development (TD) phase, but may also be conducted early in the Engineering and Manufacturing Development (EMD) phase.[1]

A preliminary design review (PDR)

evaluates the completeness/consistency of the planning, technical, and cost/schedule baselines developed during formulation. It assesses compliance of the preliminary design with applicable requirements, and determines if the project is sufficiently mature to begin the final design and fabrication phase.[2]
