Chin-Sheng Chen Florida International University T2: ESE Framework Chin-Sheng Chen Florida International University

T2. ESE Framework Definition of ESE Framework Attributes Framework is a basic arrangement, form, system, or systematic taxonomy of concepts for relating things in the real world to a presentation (in the computer world). ESE framework is a method for differentiating R&D efforts in enterprise systems engineering Attributes Enterprise element System facet Engineering activity Performance measure

Enterprise elements Definition Enterprise elements Components of an enterprise system Enterprise elements Work Decision Resources Information

Enterprise system facets Definition Different views of an enterprise system Enterprise system facets Strategy Competency Capacity Structure

Engineering Process Definition Engineering process activities Major engineering activities applied to the enterprise life-cycle process Engineering process activities Need and specification Modeling and analysis (Function) design Implementation (design)

Performance measure Definition Performance measure types The objectives which the performance of an enterprise operation is measured against Performance measure types Cost Quality Lead time Benefit (profit)

The ESE Framework Enterprise elements System facets Management Resource Information System facets Strategy Competency Capacity Structure Engineering activities Specification Analysis Design implementation Performance measure Cost Time Quality Benefit (profit)

Dimensions of the ESE R&D efforts (1) Focused on one of the three system layers Computerized managerial layer a popular focus Managerial layer Physical layer Focused on a varying scope A system element A system facet An engineering activity Engineering process

Dimensions of the ESE R&D efforts (2) Focused on an element, a facet, an activity, and a measure 4x4x4x4=256 classifications Focused on an element, a facet, and an activity 4x4x4=64 classifications. Focused on an enterprise element, a system facet, a performance measure, or an engineering activity 4+4+4+4=16 classifications Enterprise work (decision, resource, or information) system, Enterprise strategy (competency, capacity, or structure) system, Enterprise system specification (analysis, design, or implementation), Enterprise quality (time, cost, or benefit) performance Focused on engineering an enterprise element and a facet 4x4=16 classifications. Engineering work (decision, resource, or information) + strategy (competency, capacity, or structure). Focused on engineering an enterprise element or a facet 4+4=8 classifications Enterprise work (decision, resource, information, strategy, competency, capacity, or structure) system engineering Focused on each of the three system layers
