Book Description
Is it functional? Is it safe? Is it rigorous? Is it detrimental? Over the last two decades Test and Evaluation (T&E) techniques have evolved in response to the increasing complexity and interdependency of systems. The safe and proper operation of the complex systems and consumer products used in energy, transportation, electronics and communications, can no longer be realized without a formalized T&E program. Features include: Easy-to-understand guide to the seven Best Practices for planning an effective T&E program A useful model of the T&E Engineering process T&E of computer programs, Modelling and Simulation, Operational T&E and Interoperability T&E Case studies from both governmental and commercial sectors T&E resources world-wide including the addresses of local T&E chapters Purposely written with the priorities of you the program manager and systems engineer in mind. This book masterfully captures the basic principles of T&E, specifically applying them to a variety of industries. Test and Evaluation of Complex Systems forms part of the Wiley Series in Measurement Science and Technology. Chief Editor: Peter Sydenham Australian Centre for Test and Evaluation, University of South Australia. This series was founded to coincide with the recognition of measurement science and instrument technology as fields with their own scholarship and techniques.

Book Description
I have been working in Army test and evaluation (T & E) since 1974 and have seen enormous increases in the complexity of systems since I first started in the business. Systems in 1974 were largely stand-alone, analog, and mechanically controlled. Now to conduct and win the next major conflict with a conventional enemy or against violent extremist movements, previously unimagined systems are being developed and fielded to our warfighters. The complexity of these new systems is a result of addressing today's and tomorrow's threats with more accurate, lethal, reliable, survivable, interoperable, and maintainable systems. Most of today's systems are very software intensive and network enabled, and have on-board, complex subsystems. The complexities that often arise are a result of the interactions among the systems and subsystems, and as a result, they cannot be tested and evaluated in isolation. These systems are vital enablers that assist the warfighters in accomplishing their missions. These new systems are often a system of systems (SoS) on a single platform such as the mine-resistant ambush-protected (MRAP) vehicles or a family of systems such as the Future Combat Systems (FCS) and the Stryker family of vehicles. The Army Test and Evaluation Command (ATEC) uses a number of processes and best practices to T & E SoS and FoS per the policy and guidelines directed in the June 2007 Office of the Secretary of Defense Section 231 Report. Some of the challenges for the command in implementing the guidance found in the Section 231 Report are to maximize the use of mission-based test and evaluation, Modeling and Simulation (M & S), joint and distributed testing, reliability growth testing, and determining system interoperability (subsystem, system, and with multiple systems). This article discusses a few of these challenges.

Book Description
The test and evaluation of complex socio-technical systems is difficult. This is especially so when the test and evaluation (T&E) community involved tends to associate itself closely with the physical sciences. The behavioural sciences have developed methods to address such problems and have shown that these methods are capable of providing rigorous results. A discussion of the worth of qualitative data and an overview of the behavioural science methods likely to be appropriate for evaluating complex systems involving humans is provided. A minor case study illustrating the application of qualitative data analysis methods to the evaluation of the Australian Army's Battlefield Command Support System (BCSS) is discussed in order to illustrate the merit of behavioural science methods for T&E.

Book Description
This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.

Book Description
Why do enterprise systems have complicated search pages, when Google has a single search box that works better? Why struggle with an expense reimbursement system that is not as easy as home accounting software? Although this seems like comparing apples to oranges, as information and communication technologies increasingly reach into every industry

Book Description
Despite its increasing importance, the verification and validation of the human-machine interface is perhaps the most overlooked aspect of system development. Although much has been written about the design and developmentprocess, very little organized information is available on how to verifyand validate highly complex and highly coupled dynamic systems. Inability toevaluate such systems adequately may become the limiting factor in our ability to employ systems that our technology and knowledge allow us to design. This volume, based on a NATO Advanced Science Institute held in 1992, is designed to provide guidance for the verification and validation of all highly complex and coupled systems. Air traffic control isused an an example to ensure that the theory is described in terms that will allow its implementation, but the results can be applied to all complex and coupled systems. The volume presents the knowledge and theory ina format that will allow readers from a wide variety of backgrounds to apply it to the systems for which they are responsible. The emphasis is on domains where significant advances have been made in the methods of identifying potential problems and in new testing methods and tools. Also emphasized are techniques to identify the assumptions on which a system is built and to spot their weaknesses.

Book Description
A high percentage of defense systems fail to meet their reliability requirements. This is a serious problem for the U.S. Department of Defense (DOD), as well as the nation. Those systems are not only less likely to successfully carry out their intended missions, but they also could endanger the lives of the operators. Furthermore, reliability failures discovered after deployment can result in costly and strategic delays and the need for expensive redesign, which often limits the tactical situations in which the system can be used. Finally, systems that fail to meet their reliability requirements are much more likely to need additional scheduled and unscheduled maintenance and to need more spare parts and possibly replacement systems, all of which can substantially increase the life-cycle costs of a system. Beginning in 2008, DOD undertook a concerted effort to raise the priority of reliability through greater use of design for reliability techniques, reliability growth testing, and formal reliability growth modeling, by both the contractors and DOD units. To this end, handbooks, guidances, and formal memoranda were revised or newly issued to reduce the frequency of reliability deficiencies for defense systems in operational testing and the effects of those deficiencies. "Reliability Growth" evaluates these recent changes and, more generally, assesses how current DOD principles and practices could be modified to increase the likelihood that defense systems will satisfy their reliability requirements. This report examines changes to the reliability requirements for proposed systems; defines modern design and testing for reliability; discusses the contractor's role in reliability testing; and summarizes the current state of formal reliability growth modeling. The recommendations of "Reliability Growth" will improve the reliability of defense systems and protect the health of the valuable personnel who operate them.
