One of the major problems linked to design and development of any multifaceted system has always been the failure of planning along with definite identification of requirements, which cause performance lack and design failure. As a result, a well-organized approach to integrated design together with the advancement of novel systems is highly required, a system referred to as systems engineering (SE). Arguably, in systems engineering, all development facets are mainly mulled over at the primary phases, not to mention that the efforts obtained are used for incessant improvement. SE may be adequately defined as the effective application of scientific and engineering efforts with the aim of transforming a functioning necessity into a clear system organization via process of need analysis, synthesis, operational analysis and allotment, design optimization, evaluation and validation. Again, this system aims at integrating related technical constraints alongside ensuring the compatibility of all physical and functional, along with programming interfaces in a way that optimizes the total definition as well as design. Subtly, SE aims at integrating reliability, safety, reliability, maintainability, serviceability, schedule, disposability to meet cost, on top of technical performance objectives.

Excerpt from the Book
1. Reliability
Reliability as one of the main system-attributes that have great interest to system engineers, users and even logisticians can be defined as the probability of a system that performs its intended function under stated conditions, with zero failure for a particular period of time. The concept of reliability has to consist of elements such as detailed function description, time scale and the environment along with demonstrating what constitutes a failure (Girault & Valk, 2013).
Concerning design for reliability, it has been noted that system designs that are based on user needs and system design alternatives may then be formulated as well as evaluated. In this phase, reliability engineering aims at increasing system robustness via measures like, diversity, advanced diagnostics, redundancy and even modularity so as to enable rapid physical replacement (Czarnecki et al, 2000). Furthermore, there is a possibility to failure rates reduction through measures like using higher strength materials, quality components increment, moderation of the extreme environmental conditions or shortened maintenance, inspection or even overhaul intervals.
Evidently, the design analyses may include mechanical stress, radiation analyses for mechanical components, corrosion, thermal analyses for electrical and mechanical components together with EMI (electromagnetic interference) analyses or measurements for electrical sub-systems and components (Girault & Valk, 2013). One of the main obvious way to improving software reliability is through improving its quality, a context that is facilitated by more disciplined development efforts as well as test. On the other hand, reliability may also be increased through what is termed as architectural redundancy, diversity and independence. In this sense, redundancy has to be accompanied by several measures so as to ensure there is data consistency, on top of managing failure detection together with switchover.
