2 IDEF Motivation DARPA Project requires IDEF Modeling Pratt & Whitney Adept One Leadwell Sabre 500 GE-A4 Puma 760 Kardex Shuttleworth (MT1) IBM RS/6000 Shop Controller IBM RS/6000 Design Workstation TAMU Ethernet Backbone System vs. Model - continued from System Theory! Descriptive models " Graphical representation " Text description supports Graphics

3 IDEF Origin (1970 s): ICAM(Integrated Computer Aided Manufacturing) Definition Integration DEFinition Language " To build a model of real system " To analyze the built model " To design a to-be model " To transition it to the real system IDEF Model The Evolution of IDEF! A hammer is designed to pound nails. It can also be used to put in a screw or make a hole in something. But is it right tool for the job(screwing or drilling)?! Experience applying IDEF methods identified additional method needs

4 Planned IDEFs! IDEF0 - Function Modeling (Analysis)! IDEF1 - Information Modeling (Analysis)! IDEF1X - Data Modeling (Design)! IDEF3 - Process Modeling (Analysis and design)! IDEF4 - Object-oriented design (Design)! IDEF5 - Ontology description capture (Analysis)! IDEF6 - Design Rationale Capture! IDEF7 - Information System Audit Method! IDEF8 - Human-System Interaction Modeling! IDEF9 - Business-Constraint Discovery Method (Analysis)! IDEF10 - Implementation Architecture Modeling! IDEF11 - Information Artifact Modeling! IDEF12 - Organizational Design Method! IDEF13-3-Schema Architecture Design Method! IDEF14 - Network / Distribution Design Method IDEF Modeling! Purpose (Objective) " Is the reason a model is created! Viewpoint (Bias) " Establishes the goal of the communication intended by the model " Is the perspective from which a subject is analyzed " Specifies how the model will be used! Context (Subject) " Establishes the subject of a model " Is the boundaries of the subject matter

5 IDEF0 Function Modeling! Motivation: Manufacturing system function modeling! Origin: SofTech Structured Analysis and Design Technique (SADT)! June 1981, ICAM Function Modeling Manual (IDEF0) Representation of "What Do I Do?" Box = activity, action, process, operation Arrow = relationship between activities Regulations Regulations Applicant Hire Policy Hire Data Applicant People Policy Data People Fire Personnel Action Fire Customer Request People Personnel Action Customer Request People AnalysisResults AnalysisResults Promote EmployeeData Promote Reports EmployeeData People People Reports PersonnelRegulations PersonnelRegulations Department Policy Department Policy Supervisor Instructions Supervisor Instructions Manning Conditions Manning Conditions Applicant Data Applicant Data CustomerRequest Perform Personnel Action CustomerRequest Personnel Perform Personnel Action Employee/PositionData Actions Personnel Reports Employee/PositionData Actions Reports Supplies &Equipment Supplies &Equipment Personnel OfficeStaff Personnel OfficeStaff InformationSystem InformationSystem Staff Staff Eachactivity can be subdividedintocomponent Eachactivity can be subdividedintocomponent activities activities IDEF1 Information Modeling! Motivation: Capturing information, object of Manufacturing system s function! Developed by Hughes Aircraft and D. Appleton Company! June 1981, ICAM Information Modeling Manual (IDEF1) Representation of "What Must I Know to Do What I Do?" boxes = objects lines = relationship between objects Agency Name Cost Center No.ofEmployees Name Agency Dept is assigned to has Name works in accordance with LOI # Salary OCR 100 P Ops Instruction Employee creates a Serial # Type Computer is assigned toproduct Name P Date Produced requires Product P Regulation # OPR Directive

6 IDEF1X - Data Modeling! For database design! Under ICAM Program, Integrated Information Support System (IISS) Project! Origin : General Electric s Logical Database Design Technique (LDDT)! December 1985, IISS Information Modeling Manual IDEF1X E4/Account Acct-# Representation of Data Relationships and Business Rules boxes = entity lines = relationship between entities Acct-Start-Date Acct-type is a Acct-type E5/Chk-Acct E6/Save-Acct E7/Loan-Acct Acct-# Acct-# Acct-# Save-Balance Interest-Rate Chk-Balance Per-Chk-rate Loan-Balance Loan-Amount IDEF1, IDEF1X IDEF1 IDEF1X! Analysis method! Used by system analysts! Defines information Requirements! Technology independent! Results in a single requirements model! Design method! Used by database designers! Defines design criteria! Tied to relational technology! Given requirements, multiple design models are possible

7 IDEF3 Process Modeling! Motivation : Describe some activity step-by-step or by cause-effect! Under Information Integration for Concurrent Engineering (IICE) Program! Developed by Knowledge Based Systems, Inc. (KBSI)! May 1992, IICE IDEF3 Process Description Capture Method (IDEF3) Representation of "How things are done" Go-to/ Paint Part boxes = function/activity arrows = Relationship between activities Paint Part 1 Dry Part 2 Test Coverage 3 X Route to Next Stop 4 IDEF0, IDEF1, IDEF1X, IDEF3 IDEF0FunctionModel IDEF1/IX Information and Data Model IDEF3 Process Model IDEFØ " What " Whatdo doyou youdo do " Functional " Functional dependencies dependencies " No " Notime " Used " Usedto to "target" "target" activities activitiesthat thatneed improvement improvement IDEF1/1x " What " Whatdo doyou youneed needtoto know know " Information " Information Management Managementor or Database DatabaseDesign Design " Information " Informationor ordata Requirements Requirements IDEF3 " How " Howdo doyou youdo doit it " Precedence(time) " Precedence(time) or or Cause-&-Effect Cause-&-Effect " Reduce " ReduceCycle CycleTime " Improve " Improveaa specific specific process process

9 IDEF4 - Object Oriented Design! Object Oriented Program follows Object Oriented Design! Developed by Knowledge Based Systems, Inc.! IICE IDEF4 Object-Oriented Design Method Report (version 1.0) announced Jan. 1995! Improve the quality of OO code produced by novice OO programmers Data Relationships and Business Rules Redrawable-object: Redraw boxes = class lines = relationships among classes Redrawable-object: Erase Graphic-object, Text-object, Triangle, Square, Polygon: Draw IDEF0, IDEF1/1X, IDEF3, IDEF4! IDEF1X: Relational database design! IDEF4: Object-oriented database/application design Objects IDEF0FunctionModel IDEF3 Process Model

10 IDEF5 - Ontology Description Capture! An inventory of the terminology, statement structure, and sanctioned inferences in a given domain stored in a usable form " Sanctioned Inferences: Rules for deriving new information from existing information " Usable Form: Computer interpretable and re-usable in different application situations! Developed by Knowledge Based Systems, Inc. (KBSI)! IICE IDEF5 Ontology Description Capture Method Report announced 1994 Data Relationships and Business Rules boxes = kinds lines = relationships among kinds IDEF! To document! To communicate (Consensus)! To educate! To improve understanding! To capture and analyze business system and processes (System analysis)! To design new business system before coding or programming (System design)
