This book was released on 2018-11-19 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The software requirements for an implementation of Guidance and Control Software (GCS) are specified. The purpose of the GCS is to provide guidance and engine control to a planetary landing vehicle during its terminal descent onto a planetary surface and to communicate sensory information about that vehicle and its descent to some receiving device. The specification was developed using the structured analysis for real time system specification methodology by Hatley and Pirbhai and was based on a simulation program used to study the probability of success of the 1976 Viking Lander missions to Mars. Three versions of GCS are being generated for use in software error studies. Withers, B. Edward and Rich, Don C. and Lowman, Douglas S. and Buckland, R. C.

Download or read book Engineering and Managing Software Requirements written by Aybüke Aurum and published by Springer Science & Business Media. This book was released on 2006-04-07 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Requirements engineering is the process by which the requirements for software systems are gathered, analyzed, documented, and managed throughout their complete lifecycle. Traditionally it has been concerned with technical goals for, functions of, and constraints on software systems. Aurum and Wohlin, however, argue that it is no longer appropriate for software systems professionals to focus only on functional and non-functional aspects of the intended system and to somehow assume that organizational context and needs are outside their remit. Instead, they call for a broader perspective in order to gain a better understanding of the interdependencies between enterprise stakeholders, processes, and software systems, which would in turn give rise to more appropriate techniques and higher-quality systems. Following an introductory chapter that provides an exploration of key issues in requirements engineering, the book is organized in three parts. Part 1 presents surveys of state-of-the art requirements engineering process research along with critical assessments of existing models, frameworks and techniques. Part 2 addresses key areas in requirements engineering, such as market-driven requirements engineering, goal modeling, requirements ambiguity, and others. Part 3 concludes the book with articles that present empirical evidence and experiences from practices in industrial projects. Its broader perspective gives this book its distinct appeal and makes it of interest to both researchers and practitioners, not only in software engineering but also in other disciplines such as business process engineering and management science.

Download or read book Software Requirement Patterns written by Stephen Withall and published by Pearson Education. This book was released on 2007-06-13 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learn proven, real-world techniques for specifying software requirements with this practical reference. It details 30 requirement “patterns” offering realistic examples for situation-specific guidance for building effective software requirements. Each pattern explains what a requirement needs to convey, offers potential questions to ask, points out potential pitfalls, suggests extra requirements, and other advice. This book also provides guidance on how to write other kinds of information that belong in a requirements specification, such as assumptions, a glossary, and document history and references, and how to structure a requirements specification. A disturbing proportion of computer systems are judged to be inadequate; many are not even delivered; more are late or over budget. Studies consistently show one of the single biggest causes is poorly defined requirements: not properly defining what a system is for and what it’s supposed to do. Even a modest contribution to improving requirements offers the prospect of saving businesses part of a large sum of wasted investment. This guide emphasizes this important requirement need—determining what a software system needs to do before spending time on development. Expertly written, this book details solutions that have worked in the past, with guidance for modifying patterns to fit individual needs—giving developers the valuable advice they need for building effective software requirements

Download or read book A Methodology for Software Specification and Development Based on Simulation written by G. F. DE LA Mora and published by . This book was released on 1991 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the methodology presently used for specification and development of guidance and control software (GCS) referred to as the phased approach. This methodology is shown to present basic shortcomings in relation with the requirements specification phase: long development time, reverse engineering tasks and inadequate handling of errors. In order to solve these problems, a new methodology, the simulation based approach, is presented. This new methodology is based on the fact that any requirements specification for control software is preceded by a simulation task, that includes the design, code and test of the GCS. As a consequence, the GCS is developed twice, once in the simulation, and then in the flight software. The new methodology proposes to build the GCS only once, and through the use of two basic tools: simulation and rapid prototyping, cuts through the main shortcomings of the phased approach.

Learn how to: Clarify problems, define business objectives, and set solution boundaries Identify stakeholders and decision makers Explore user tasks, events, and responses Assess data concepts and relationships Elicit and evaluate quality attributes Analyze requirements and requirement sets, create models and prototypes, and set priorities Specify requirements in a consistent, structured, and well-documented fashion Review, test, and manage change to requirements "I once read the ten best-selling requirements engineering books of the prior ten years. This one book succinctly presents more useful information than those ten books combined." --Mike Cohn, author of User Stories Applied and co-founder, Scrum Alliance "Diamonds come about when a huge amount of carbon atoms are compressed. Karl and Candase have done something very similar: they have compressed their vast requirements knowledge into 20 gems they call 'core practices.' These practices are potent stuff, and I recommend that they become part of everyone's requirements arsenal." --James Robertson, author of Mastering the Requirements Process and Business Analysis Agility "Long story short: if you are going to read only one requirements book, this is it. Software Requirements Essentials distills the wealth of information found in Software Requirements and many other texts down to twenty of the most important requirements activities that apply on nearly all projects. Today's busy BA simply doesn't have the time to read a lengthy instructive guide front-to-back. But they should find the time to read this book." --From the Foreword by Joy Beatty, COO, ArgonDigital "Software Requirements Essentials will be a high-value addition to your business analysis library. Anyone looking to improve their business analysis practices will find great practical advice they'll be able to apply immediately." --Laura Paton, Principal Consultant, BA Academy, Inc.
