Available in PDF, EPUB and Kindle. Book excerpt: The National Aeronautics and Space Administration (NASA) is undertaking one of its most ambitious projects ever-Space Station Freedom. As part of this effort, NASA has started developing computer software that will drive the station's 10 main on-board computer systems. This software will perform critical functions ranging from keeping the station in its proper orbit to maintaining life support of the crew. In contrast with the space shuttle, software development for the station will be highly dispersed, with three prime contractors and scores of subcontractors across the country developing millions of lines of computer software code. This software is meant to last for the station's entire life-three decades. Given the risks inherent in such a large, complex undertaking, the House Committee on Science, Space, and Technology asked GAO to determine (1) if independent verification and validation techniques are being used to ensure that critical software meets specified requirements and functions; (2) if NASA has incorporated software risk management techniques into the program; (3) whether standards are in place that will prescribe a disciplined, uniform approach to software development; and (4) if software support tools will help, as intended, to maximize efficiency in developing and maintaining the software.

This book was released on 1993-02-01 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective software is essential to the success and safety of the Space Shuttle, including its crew and its payloads. The on-board software continually monitors and controls critical systems throughout a Space Shuttle flight. At NASA's request, the committee convened to review the agency's flight software development processes and to recommend a number of ways those processes could be improved. This book, the result of the committee's study, evaluates the safety, oversight, and management functions that are implemented currently in the Space Shuttle program to ensure that the software is of the highest quality possible. Numerous recommendations are made regarding safety and management procedures, and a rationale is offered for continuing the Independent Verification and Validation effort that was instituted after the Challenger Accident.

Download or read book Essentials of Project and Systems Engineering Management written by Howard Eisner and published by John Wiley & Sons. This book was released on 2011-11-17 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Third Edition of Essentials of Project and Systems Engineering Management enables readers to manage the design, development, and engineering of systems effectively and efficiently. The book both defines and describes the essentials of project and systems engineering management and, moreover, shows the critical relationship and interconnection between project management and systems engineering. The author's comprehensive presentation has proven successful in enabling both engineers and project managers to understand their roles, collaborate, and quickly grasp and apply all the basic principles. Readers familiar with the previous two critically acclaimed editions will find much new material in this latest edition, including: Multiple views of and approaches to architectures The systems engineer and software engineering The acquisition of systems Problems with systems, software, and requirements Group processes and decision making System complexity and integration Throughout the presentation, clear examples help readers understand how concepts have been put into practice in real-world situations. With its unique integration of project management and systems engineering, this book helps both engineers and project managers across a broad range of industries successfully develop and manage a project team that, in turn, builds successful systems. For engineering and management students in such disciplines as technology management, systems engineering, and industrial engineering, the book provides excellent preparation for moving from the classroom to industry.

Download or read book International Space Station ISS Systems Engineering Case Study written by Air Force Center for Systems Engineering and published by . This book was released on 2017-12-04 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This case study on the International Space Station considers what many believe to have been the ultimate international engineering project in history. The initial plans involved the direct participation of 16 nations, 88 launches and over 160 spacewalks-more space activities than NASA had accomplished prior to the 1993 International Space Station decision. Probably more important was the significant leap in System Engineering (SE) execution that would be required to build and operate a multi-national space station. In a short period of time, NASA and its partners had to work out how to integrate culturally different SE approaches, designs, languages and operational perspectives on risk and safety. The International Council on Systems Engineering (INCOSE) defines Systems Engineering (SE) as an "interdisciplinary approach and means to enable the realization of successful systems. It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, and then proceeding with design synthesis and system validation while considering the complete problem: operations, performance, test, manufacturing, cost and schedule, training and support, and disposal." One of the objectives of the Air Force Center for Systems Engineering (AFCSE) is to develop case studies focusing on the application of systems engineering principles within various aerospace programs. The intent of these case studies is to examine a broad spectrum of program types and a variety of learning principles using the Friedman-Sage Framework to guide overall analysis. These cases support practitioners of systems engineering and are also used in the academic instruction in systems engineering within military service academies and at both civilian and military graduate schools.

Download or read book NASA System Safety Handbook written by Homayoon Dezfuli and published by . This book was released on 2012-02-27 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: System safety is the application of engineering and management principles, criteria, and techniques to optimize safety within the constraints of operational effectiveness, time, and cost throughout all phases of the system life cycle. System safety is to safety as systems engineering is to engineering. When performing appropriate analysis, the evaluation is performed holistically by tying into systems engineering practices and ensuring that system safety has an integrated system-level perspective.The NASA System Safety Handbook presents the overall framework for System Safety and provides the general concepts needed to implement the framework. The treatment addresses activities throughout the system life cycle to assure that the system meets safety performance requirements and is as safe as reasonably practicable.This handbook is intended for project management and engineering teams and for those with review and oversight responsibilities. It can be used both in a forward-thinking mode to promote the development of safe systems, and in a retrospective mode to determine whether desired safety objectives have been achieved.The topics covered in this volume include general approaches for formulating a hierarchy of safety objectives, generating a corresponding hierarchical set of safety claims, characterizing the system safety activities needed to provide supporting evidence, and presenting a risk-informed safety case that validates the claims. Volume 2, to be completed in 2012, will provide specific guidance on the conduct of the major system safety activities and the development of the evidence.
