1、 TechAmerica Engineering Bulletin Reliability Program Handbook TA-HB-0009 May 2013 TA-HB-0009NOTICE TechAmerica Engineering Standards and Publications are designed to serve the public interest by eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and
2、improvement of products, and assisting the purchasers in selecting and obtaining with minimum delay the proper product for their particular needs. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of TechAmerica from manufacturing or selling produ
3、cts not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TechAmerica members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by
4、 TechAmerica in accordance with the American National Standards Institute (ANSI) patent policy. By such action, TechAmerica does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. Technical Publications are distin
5、guished from TechAmerica Standards in that they contain a compilation of engineering data or information useful to the technical community and represent approaches to good engineering practices that are suggested by the formulating committee. This Bulletin is not intended to preclude or discourage o
6、ther approaches that similarly represent good engineering practice, or that may be acceptable to, or have been accepted by, appropriate bodies. Parties who wish to bring other approaches to the attention of the formulating committee to be considered for inclusion in future revisions of this publicat
7、ion are encouraged to do so. It is the intention of the formulating committee to revise and update this publication from time to time as may be occasioned by changes in technology, industry practice, or government regulations, or for other appropriate reasons.

Engineering Process 2.1.1. Purpose The objective of the Engineering Process (EP) is to design and produce a func
10、tional, reliable, and robust system/product. This means that the system/product performs its intended function in the full spectrum of the potential environments and use, it is economical to produce, and it is easy to maintain. From a Reliability Engineering perspective, this goal can be supported b
11、y employing a Failure Mode/Mechanism Management strategy that is based on robust Design for Reliability (DFR) principles. An effective EP comprises a two-step Reliability Process that first proactively identifies a comprehensive set of potential failure modes along with their accelerating mechanisms
12、 and root causes, and, secondly, mitigates them based on a specific prioritization method that accounts for critical functionality from the component level up and the system/product level down. This type of EP will produce not only a functional design, but also a reliable and durable one. An EP that
13、 employs DFR principles during design, development, production, and customer use over the system/product life cycle will minimize waste and potential future re-work, thereby maximizing the total life cycle cost savings. The Inputs, Outputs, Enablers, and Constraints associated with an effective Engi
14、neering Process are shown in Figure 2.1-1. Similarly, Table 2.1-1 shows the inputs and outputs of the EP, but adds a more detailed discussion of the processes and interfaces that take place. Note that the Inputs and Outputs of Table 2.1-1 are worded differently than those in Figure 2.1-1. This is do
15、ne to further characterize these items because of the complexity of the EP. For instance, the two Figure 2.1-1 Inputs for Objective 1, Customer Reliability Requirement and System, Subsystem Component Requirement, are further described as Design Concept Ideal/Intended Functions and Product Boundaries
16、 and Levels of Detail, respectively in Table 2.1-1.
