Classical ESS-ESS where screening levels are not determined and continuously modified through quantitative means such as those found in Mil-Hdbk-344. Defect: Latent Defect-An inherent or induced weakness, not detectable by ordinary means, which will either be precipitated to early failure under environmental stress screening conditions or eventually fail in the intended use environment. Patent Defect-An inherent or induced weakness which can be detected by inspection, functional test, or other defined means. Defect Density-The average number of defects per item. Detection Efficiency-A measure of the capability of detecting a patent defect. Environmental Stress Screening (ESS)-A process or series of processes in which environmental stimuli, such as rapid thermal cycling and random vibration, are applied to electronic items in order to precipitate latent defects to early failure. Failure-Free Period-A contiguous period of time during which an item is to operate without the occurrence of a failure while under environmental stress. Fallout-Failures observed during, or immediately after, and attributed to stress screens. Fallout Analysis-The study of fallout failures for the purpose of modifying screens. Fault Replication Test Method-A method used to generate a satisfactory initial vibration screening level by gradually increasing the stress level until previously known faults are precipitated. Final Acceptance Test-The environmental test used to validate that customer mean time between failure or failure-free requirements have been achieved. Final acceptance test is usually conducted after ESS. Fixture-The apparatus used to mount the electronic equipment on the vibrator/shaker machine. Flaw Precipitation Threshold Method-A method used to generate a satisfactory initial vibration screening level by performing a vibration survey and then performing detailed computations on the global responses within the test specimen. This method is also referred to as the "Tailored Spectral Response" method. Functional Test Program-Procedures associated with testing the functionality of electronic equipment.

Rome Laboratory is undertaking many initiatives to ensure the reliability and maintainability (R&M) of the next generation of commercial and military systems developed in this new acquisition environment. Several R&M specifications and standards reform initiatives are underway which include: developing nongovernment replacement standards; developing military handbooks; and forming partnerships with industry associations and professional societies. In addition to the new standardization activities, Rome Laboratory is also undertaking a number of research activities to help implement Acquisition Reform. Process oriented approaches to assure system reliability at all levels of indenture are being developed. It is recognized that indiscriminate acceptance of commercial products without adequate reliability assessment may adversely affect system reliability and readiness. To alleviate this concern, Rome Laboratory is assessing the reliability of commercial parts, nondevelopmental items, and plastic encapsulated microcircuits in military equipment environments. By providing an overview of these activities, this paper reveals the great impact Acquisition Reform is having on R&M standardization and on the direction of research at Rome Laboratory

JADE is being developed by BBN Technologies under contract to the Air Force Research Lab and the Defense Advanced Research Projects Agency (DARPA). It is being designed to operate within the next generation Global Command and Control System. JADE implements state of the art technology to reduce the time typically required for building a Time Phased Force Deployment Data package, which presently takes days or weeks, down to approximately one hour. In order to support the command and control needs of planners today and in the twenty-first century, several challenges are being met to transition JADE from a research prototype to a fully operational system. These include integrating various data systems, seeking user input and buy-in, porting to new computing environments, assuring compliance with the Defense Information Infrastructure Common Operating Environment, and testing in exercise scenarios. A potential technology transition candidate for JADE is the Adaptive Course of Action (ACOA) program. ACOA is a DARPA advanced conceptual technology demonstration (ACTD) that provides the means to employ new technologies in the Joint Operations Planning and Execution environment. The ACOA tool suite is also a key enabler in achieving Joint Vision 2010. In this paper, a detailed overview of JADE is provided along with plans for technology transition. 1.0 JADE Overview JADE demonstrates breakthrough technology that enables a military planner to build a force deployment plan, including a Time Phased Force Deployment Data (TPFDD) package in less than one hour. JADE is a knowledge-intensive planning technique that employs case-based and generative planning methods to handle large-scale, complex plans in minimal time. The tool is capable of rapid retrieval and reuse of previous plan elements and employs an easy to use maporiented drag and drop interface. Force modules from previous plans whose force capabilities and composition satisfy the current situation can be dragged from the plan library (casebase) and dropped onto a geographic destination. Constraint checking is conducted during plan

In 2001, the Information Directorate of the Air Force Research Laboratory (AFRL) initiated an advanced technology demonstration program in the area of effects based operations. The program set out to develop new concepts and a software toolset to meet the AOC requirement for effects based targeting and campaign assessment. At the core of the toolset are the Strategy Development Tool (SDT) and Causal Analysis Tool (CAT). The Strategy Development Tool guides the user through the development of effects based COAs. During the initial planning phase, the Causal Analysis Tool predicts the probability of achieving commander's intent for the effects based COAs. During execution, the Causal Analysis Tool acts as a campaign assessment tool by incorporating accrued evidence provided by a multi-intelligence fusion component. An attrition-based campaign level wargaming tool was also developed to supplement COA analysis The goal is to transition the software tools to AOC strategists to help them achieve an effects based approach to the COA development process described in Joint Publication 3-30, "Command and Control for Joint Air Operations." Though focused on air operations, the tools can be used at the Joint Force Command level as well.
