By Renee Stevens

With their skill to move conventional limitations and attain a degree of performance more than their part components, mega-systems have helped companies and executive businesses worldwide unravel advanced demanding situations that they differently couldn’t tackle with stand-alone structures. Engineering Mega-Systems: The problem of platforms Engineering within the info Age offers a transparent figuring out of the engineering of this type of systems—a strategy that calls for attention of accelerating software scale and the speedy switch of underlying applied sciences. Written through Renee Stevens, a Senior central Engineer on the MITRE company with many years of expertise studying, engineering, and buying large-scale platforms for the U.S. division of protection and different govt companies, this e-book explains how the engineering of mega-systems is inherently varied from that of large-scale monolithic structures. It provides the vocabulary and framework had to discover the problems correct to mega-systems. This framework then evolves into the Profiler diagnostic instrument that helps you comprehend the character and context of the process to hand and, on that foundation, decide upon the main acceptable tactics, instruments, and strategies. Stevens examines advertisement and govt functions of mega-systems to supply perception into the modern demanding situations of engineering those structures in 3 serious dimensions: engineering tactics, administration tactics, and the bigger context within which those platforms are constructed and deployed. whole with case reviews in engineering mega-systems that illustrate precious classes discovered and spotlight rising practices, this ebook offers the knowledge and the instruments had to commence engineering, characterizing, and buying mega-systems throughout a number of dimensions.

Yet, at the same time, government agencies and corporations are 26 ◾ Engineering Mega-Systems hampered by the existing inventory of systems—often referred to as legacy systems. These systems may have been developed for specific parts of the enterprise, are often tailored to local needs, and can be difficult to adapt to the new business models. Rather than enabling interconnectivity and interoperability, these legacy systems constitute barriers. For example, General Motors (GM) discovered that the company had more than a dozen SAP AG13 systems deployed globally, each of which was a different release and was used in slightly different ways.

And coalition forces and non-government organizations. This translates into capabilities to enable: ◾⊾ Superior decision making across multiple dispersed and distributed command elements, including those of multinational forces ◾⊾ Shared understanding among all friendly elements on the battlefield, including those of non-governmental organizations, which can include such diverse organizations as the Red Cross and Doctors Without Borders ◾⊾ The ability to support tailorable organizations that may be constructed dynamically to accomplish a particular mission ◾⊾ Operation-wide integration, including access to all weapons authorized to accomplish the mission Underlying these capabilities is an infrastructure with attributes that include universal communications—defined as available and trustworthy means to communicate with any authorized person, system or weapon anywhere—secure information, data interoperability, and command and control systems that are 16 ◾ Engineering Mega-Systems easy to use.

For example, the automotive industry uses extranets to cut down on its redundant ordering processes and keep suppliers up-to-date on parts and design changes, thereby shortening response times to suppliers’ problems and questions. Suppliers can receive proposals, submit bids, provide documents, or collect payments through an extranet site. Because an extranet has restricted access, it can be connected directly to a company’s internal systems. 4╇Mobile Society, Wireless Lifestyle The emerging wireless lifestyle goes well beyond the use of cellular phones and pagers to a fundamental extension of the Internet from a fixed, wired environment to one that is wireless, allowing access to information anywhere and anytime.
