Conforming requirements to customer need

When preparing the development prototype, this task again confirms and validates that the features of the product meet customer needs. This is accomplished through focus groups, meetings, and simulations in which customers interact with the product in local settings. Table 5-3 shows the template for capturing data.

Preliminary Design Review

The purpose of a preliminary design review is to identify product and equipment design issues and potential problem areas before they become major reliability risks, and before the prototype is built and tested. Preliminary equipment design reviews concentrate on the design of the entire product as a system. The preliminary review raises issues that become the agenda for a full design review later in this stage, and for project review.

At this stage, the design of product components and equipment are still evolving. Therefore, the design process is not ready to turn out a configured product ready for production. But this review helps to status the design process and surface challenges.

The design review meeting brings together all the stakeholders in the product design. The agenda is heavily oriented toward engineering issues, but other problems, e.g., schedule and customer requirements, typically come up. The program manager prepares the agenda. A lead engineering facilitator leads the meeting, and appropriate subject matter experts participate as needed. Drawings, documents, and graphics are projected for group review and discussion, and items are recorded for follow-up and attention during gate review.

The issues reviewed in the meeting include:

1. Confirm specifications

■ Status of customer needs document

■ Status of product specifications document

■ General status of equipment design activity

2. Identify Design Issues

■ Performance requirements

■ Design approach

■ Review of equipment and layout drawings

■ Applicable design standards and tolerances

■ Design trade studies

■ Applicable design models

■ Environmental and green issues

■ Preliminary Bill of material

■ Producibility and manufacturing issues

■ Test requirements

■ Reliability requirements (preliminary to full Reliability Assessment)

■ Robust design goals and issues

■ Critical parts review

■ Test Readiness review items

■ Safety and regulatory issues, e.g., electrical grounding

■ Unanswered design questions, e.g., material specifications, potential supplier design problems, cost

The outputs include:

1. Prepare Design Issues Document—This task requires a design engineer to produce a design issues document that guides the preliminary design review meeting and follow-up action. This document identifies design issues, such as:

■ Size and function of critical parts

■ Tolerances

■ New technologies

■ Form and features

■ Design options and alternatives, e.g., materials, etc.

2. Conduct Review Meeting—The preliminary review meeting agenda includes:

■ Review of design documents, drawings, etc.

■ Design definitions

■ Review of design and functionality of product

■ Review of design issues document, e.g., potential design risks

■ Bill of materials and parts list

■ Supplier issues

■ Generation of follow-up actions and responsibilities

3. Design Review Matrix Template—A design review matrix is prepared and used to guide preliminary review and follow-up. Table 5-4 shows a design review matrix.
