The purpose of the initial design review is to determine the potential fit of the product to the manufacturing facility, determine general cost information, and prepare for tooling. Proper upfront analysis of a product prior to manufacturing or tooling saves time and materials. 

After the initial design review, the basics of the design are known and a decision on whether to manufacture the design has to be made. If it is decided to proceed with manufacturing, the cost of the product must be determined. Once the cost has been determined, the product price can be provided to the PCB customer. 

Design analysis and review is a refinement of the initial design review performed earlier but is the first step in the CAM (soft-tooling) process.This step focuses on the actual design data submitted for fabrication and assembly. The design analysis and review step consists of the following tasks ... 

Additionally, the factors reviewed during the initial design review are revisited to confirm the results based on design actuals. If differences are noted, product yields and/or cost predictions may need to be altered. 

In the panelization process, the PCB single images are placed in the locations defined in the panelization definition step of the initial design review. In addition, the following features may be added to the panel for manufacturing ... 

Checklists also provide a common basis for management review of assessments. Many organizations use standard checklists to control the development of a process or an entire project from initial design through decommissioning. The completed checklist must be approved by all relevant staff members and managers before a project can move from one stage to the next. 

Design reviews are conducted to refine requirements. Hazards are introduced to plant operators following laboratory work, EHS review, capital requirements review, and process hazard analysis. Reactivity is addressed during process hazard analysis and the initial review. 

Hazard reviews are generally conducted progressively and in increasing detail during a project to ensure that hazards have been identified and that appropriate hazard mitigation has been applied. The outcome of hazard reviews should form the basis for the initial design and subsequent development of the fire protection system. It is not unusual that, as the overall project... 

The results of the risk analysis review must be documented. To adequately analyze the risks, a comprehensive requirements specification deliverable is required. The best time to perform an initial risk analysis is immediately after the project team has completed the review of the requirements specification deliverable. The review of the solutions agreed upon and implemented as a result of the risk analysis should be performed during a technical design review. 

The Requirements Traceability Matrix (RTM) initially developed for the Design Review should be extended to track which tests cover which aspects of the specification.

Use DFMEA during your preliminary, initial, and detail design reviews to uncover any potential failure modes. Then your first priority is to prevent these modes by improving the design itself (see Mistake Proofing, Technique 49). If you can t mistake-proof your solution (as in the foot-on-brake example), your next priority is to detect a failure mode before it occurs and prompt the user to take action. The oil warning light in a vehicle is an example of this approach. 

The original and existing design basis of equipment should be reviewed and compared with current codes, standards, and legislative requirements. As-built documentation should also be reviewed to identify those areas from the initial design that may need to be reconsidered for the purposes of life extension.
