A Framework for Complex System Development

Abstract

INTRODUCTION Is a Structured Approach Needed Technical and Managerial - Integration is Essential Motivation Objectives Key Questions Defined in the Literature Working Definition of LITERATURE SEARCH AND RATIONALE FOR THIS BOOK Existing and Emerging Standards Individual Works The Basic Building Block Unique Features of this Book Time and Logical Domains Tier Connectivity Modularity Coupling of Technical and Managerial Activities Clear Presentation of Functional Decomposition Explicit Inclusion of the Rework Cycle Explicitly Defined Generalized Outputs SYSTEM DEVELOPMENT FRAMEWORK (SDF) OVERVIEW Two Views Needed for an Accurate Model Rationale An Illustration Time and Logical Domain Views Provide a Full Program Description Time Domain Focus: Inputs and Outputs Logical Domain Focus: Energy Expenditure The SDF in the Logical Domain Control Logic Hierarchy Modularity Closed Loop Traceability Comprehensiveness Convergence Risk The SDF in the Time Domain Incremental Solidification Risk Tolerance Defines Scope Time-Phased Outputs System Life Cycle THE REWORK CYCLE is the Rework Cycle? A Simple System Dynamics Model Rework Mitigation SYSTEM DEVELOPMENT FRAMEWORK - TECHNICAL Develop Requirements - Determine What the System Must Do Inputs Work Generation Activities Derive Context Requirements Generate Functional Description Digression: Why Functional Analysis? Rework Discovery Activities Analyze Requirements Analyze Functional Description Synthesis Work Generation Activities: Design and Integration Design Analysis Allocation Functional Decomposition Inter-Level Interface Integration Rework Discovery Activities: Design Verification Analysis and Test Producibility, Testability, and Other Specialty Engineering Activities Trade Analysis Optimization and Tailorability Optimization Tailorability The Integrated System Development Framework THE SYSTEM DEVELOPMENT FRAMEWORK - MANAGERIAL Integrating Technical and Managerial Activities Developing the Program Structure Interaction in the Logical Domain Interaction in the Time Domain A Note on Complexity Major Milestone Reviews About Metrics A POTPOURRI OF SDF-DERIVED PRINCIPLES General Risk Functional Analysis Allocation Process Iteration Reviews Metrics Twenty Cs to Consider APPENDIX A SMALL PRODUCT DEVELOPMENT AND THE SDF APPENDIX B TAILORED DOCUMENTATION WORKSHEET APPENDIX C SDF-DERIVED MAJOR MILESTONE REVIEW CRITERIA APPENDIC A SDF-DERIVED CURRICULUM APPENDIX E MAPPING EQFD AND ROBUST DESIGN INTO THE SDF APPENDIX F A SIMPLE SYSTEM DYNAMICS MODEL OF THE SDF APPENDIX G SDF PRESENTATION SLIDES
