1. I. Preliminary Design Review 1. Product specification 2. Project scope 3. Technical approach/solution to the Design Problem 4. Working Schedule (Gantt Chart) 5. Identification of all deliverables, such as.... This review should take place no later than the second week into the project (first week for summer projects). This review should begin with a presentation which covers the following:

2. Typical Candidate Deliverables (PDR)  Product specification  Equipment Acceptance Test Procedure (ATP)  Environmental Qualification test plans/procedures  Bills of Materials and Cost data  Parts Procurement Specifications  Assembly procedures/drawings  Acceptance/qualification test reports  Engineering Prototype/Feasibility Model  Installation Instructions  Users Manual

3. PDR (Continued) 1. The feasibility of the technical approach. 2. The viability of the project schedule. 3. Release (sign off) of the product specification. Following the presentation, the design team and reviewers enter into a discussion wherein agreement is reached with regard to: The meeting minutes should contain the final, agreed upon list of deliverables. Any shortcomings must be noted and published with the meeting minutes as Action Items, and the PDR milestone is not to be considered met until all action items are resolved.

4. II Critical Design Review This review should take place at a point where 70% - 80% of the time allotted has passed. A stand up presentation or hardware demonstration may or may not be appropriate at this review. 1. Performance against the published project schedule is evaluated, and a judgment is made as to whether the schedule remains viable, or if adjustments must be made.

5. CDR (Continued) 2. Test plans/procedures are to be reviewed to verify that they are sufficient to determine compliance with the product specification. 3. A functional demonstration of a brass- board or engineering model is often appropriate at this juncture.

6. CDR (Continued) 4. Any omissions or inconsistencies in the documentation must be noted and published with the meeting minutes as Action Items. The CDR milestone is not to be considered met until all action items are resolved, and essentially all drawings relevant to the construction/production of the product are released.

7. Drawing Release To "release" a drawing, specification, or other document means that it has been signed off by the project engineer as "Revision Zero" and henceforth comes under configuration management. Implicit in the sign off is the conviction on the part of the project engineer that the drawing is essentially complete, correct, and useable.

8. Change Orders Any changes made to documents after release must be accomplished through the Engineering Change Order (ECO) process, and the revision designator increased accordingly. Refer to 000-0010-00 for Assignment, Release, and Document Change protocol.000-0010-00

9. III Conformity Inspection 1. All deliverables specified in the PDR Minutes are accounted for. 2. Tested hardware is examined to determine conformity with current revision documentation. 3. Test reports are examined to verify equipment performance consistent with the project specification.

10. Conformity Inspection (Cont) To pass the conformity inspection one hundred percent, the inspected hardware must: 1.Be built according to current revision engineering drawings 2.Be tested according to current revision test procedures 3.The test procedures must thoroughly and rigorously verify performance against the project specification.
