T2. ESE Framework

• Definition of ESE Framework
• 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 RD
  efforts in enterprise systems engineering
• Attributes
• Enterprise element
• System facet
• Engineering activity
• Performance measure

Enterprise elements

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

4
Enterprise system facets

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

5
Engineering Process

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

6
Performance measure

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