IDEF Do. D FEAC 1 • Created in the late ‘ 70 s • IDEF stands for Integrated DEFinition Language. • Provides a common, public-domain language for modeling and describing: – – Processes Data Requirements Functions • Has been used to improve hundreds of enterprises • IDEF is a standard modeling technique for all US Government agencies, and many private companies.

Do. D FEAC 1 Effective Engineering Requires a Blueprint • Models are a basic necessity for building everything from houses to cars; marketing plans to financial forecasts. • Modeling gives you a clear picture of the current situation, as well as a plan for the future. • A model helps concepts evolve to plans and prototypes. • Modeling a structure or solution is especially worthwhile when implementation goals are obvious and important.

Do. D FEAC 1 IDEF is tool for. . . describing. . . managing. . . and improving complex processes and systems To do this, we need a common framework for visualizing the processes and the systems they support, and a methodology for representing both.

Do. D FEAC 1 A process is any set of managed, predictable behaviors. Frustration Involution Consolidation Competition Opportunity Business Process Lifecycle Innovation Rationalization Rapid Growth

Do. D FEAC 1 Process Management The goal of process management is to minimize costs through: • Rationalization, • Consolidation, • Involution, • and to maximize the benefits of innovation, growth, and change.

Do. D FEAC 1 What are the Processes Doing? • The goal is to improve the management of both tangible and intangible assets according to a longrange plan while achieving continuous improvement. Since assets are all that an organization (and men and women) have, this is all that the goal can be.

Do. D FEAC 1 Varieties of Models come in many shapes and sizes: – – – Process Vs Data models Text Vs Graphic-based models High- Vs Low-level models Flat Vs Hierarchic models Degree of rigor in the modeling methodology Representation of additional detail: timing, data states, business rules. . .

Do. D FEAC 1 Model Vs Reality Models represent reality in a form that can be easily controlled, evaluated, and manipulated. Complex, poorly understood processes become manageable when broken down into their component parts. Models can be used for analysis of the simplest processes; or the most complex systems with lifecycle costs in the millions of dollars

Do. D FEAC 1 Activity Modeling links the organization to its strategic goals. • Simplification of Value-Added Activities • Consolidation of Value-Added Activities • Elimination of activities that do not add value • Automated support only after basic business processes are efficient and effective. • Provides the basis for analysis and continuous improvement.

Do. D FEAC 1 Levels of Analysis • Strategic overview-- examination of the corporation as a whole, focusing on mission and long range goals and objectives. • Mid-level analysis of management, culture, and organizations. • Detailed look at individual processes. All analyses are done in terms of time, cost, and quality

Do. D FEAC 1 Process Analysis IDEF models gather the data for analysis: Cost: Activity-based costing, functional economic analysis Time: Timeline, cycle time, run time, turn-around times, sequence, hierarchy, dependencies. Quality: Quality metrics, comparisons between past, present, and future , TQM, CQI. Redundant, over-lapping, non-valueadded processes become apparent while building the model.

Do. D FEAC 1 IDEF Methodology Components • IDEF 0 - Function and process modeling Answers the question - WHAT DO I DO? • IDEF 1 X - Entity-Attribute-Relationship data modeling- Answers the question WHAT DO I NEED TO KNOW TO DO WHAT I DO? –IDEF 2 - Process simulation modeling Answers the question - WHEN DO I NEED TO KNOW WHAT I NEED TO KNOW , TO DO WHAT I DO?

Benefits • Do. D FEAC 1 IDEF 0 reveals redundant and non-valueadded processes. • IDEF 0 documents the AS-IS-- the processes, the relationships between them, and the logical breakdown of those functions into their subprocesses and properties for baseline evaluation and further analysis. • IDEF 0 begins the road map from the AS-IS to the TO-BE.

Benefits Do. D FEAC 1 (continued) • IDEF 0 provides a means for communicating and • • presenting results. IDEF 0 establishes a forum and a structure for data gathering and knowledge acquisition. IDEF 0 identifies opportunities for improvements. IDEF 0 reveals data relationships and incongruities. IDEF 0 identifies and categorizes information entities which form the foundation for information modeling (IDEF 1 x).

Do. D FEAC 1 IDEF is not a substitute for. . . thinking. . . intelligence. . . or experience, But it can expose their absence.
