  1. INCOSE NDIA SYSTEM DEVELOPMENT POWERHOUSE This presentation offers National Defense Industrial Association (NDIA) Systems Engineering Conference occurring October 20-23, 2003 at the Hyatt Regency Ilandia Hotel in San Diego, California is a portion of a four hour presentation (a subset of an 18 day system engineering course of study) covering the four fundamental areas of excellence required for an enterprise to satisfy the presentation title. Jeffrey O. Grady President JOG System Engineering, Inc. 6015 Charae Street San Diego, CA 92122 (858) 458-0121 jeff@jogse.com http://www.jogse.com

  3. First, what is a system? SYSTEM SYSTEM ENVIRON-MENT A collection of entities that interact through relations to achieve common purpose.

  4. Is Your Company a Powerhouse of System Engineering? OUPUT INPUT PROCESS Or is it only wishful thinking that it could be.

  5. The Answer is in the Process

  6. The Simple Secret to Successful System Development • Define the problem • Synthesize a solution • Engineering design • Acquisition of material • Manufacturing • Prove that the solution satisfies the requirements • Accomplish all three steps within the context of a sound management infrastructure

  7.

  13. Define Product Requirements - Requirement Defined Something wanted or necessary. ITEM Something essential to the existence or occurrence of something else. Of what items must a system consist and how can I communicate needed characteristics for those items to designers? A necessary character- istic or attribute of some thing (or item). REQUIREMENTS ARE THE ANSWER!

  14. Kinds of Product Requirements SOFTWARE REQUIREMENTS SYSTEMS AND HARDWARE REQUIREMENTS PERFORMANCE REQUIREMENTS (ENTITY CAPABILITIES) FUNCTIONAL REQUIREMENTS (ENTITY CAPABILITIES) NON-FUNCTIONAL REQUIREMENTS SPECIALTY ENGINEERING REQUIREMENTS INTERFACE REQUIREMENTS ENVIRONMENTAL REQUIREMENTS DESIGN CONSTRAINTS

  16. Systems and Hardware Structured Analysis Models • Traditional structured analysis • Flow diagramming • Enhanced flow diagramming • Behavioral diagramming • IDEF-0 • Process diagramming • State diagramming • FRAT • Quality function deployment (QFD)
