2. T9: Enterprise systems design
Process:
System analysis and specification
System modeling and analysis
System design
System implementation design
System deployment design

3. Need analysis
Define scope (application industry & business scope) to support
Outline the overall enterprise (system) lifecycle to support
Define business performance measures and control requirements to support
Define major business/engineering/project functions (& structure) to support
Define operation/production strategy to support
Define the nature of organization (& structure) to support
Define the nature of work (& structure) to support
Define the generic strategic decision process to support
Define the generic operational decision/execution process to support

4. System specification
Translate the above needs into system specifications (functionality requirements)
Develop benchmarks (metrics and values) for the system

5. System modeling and analysis
Model (& decompose) business functions for intended application scope
Model (& decompose) business objects for intended application scope
Resources capability and capacity
Model (& decompose) business processes (i.e., object dynamics) for intended application scope
Status, state, trigger event & control, actor, & activity (method)

6. System design (1) Determine system configuration capability to support
Add/modify enterprise strategies
Add/modify system parameters
Add/modify functional modules
Add/modify business processes
Add/modify workflows & its parameters

7. System design (2)
Determine strategies for ramp-up, operation modes and upgrades to support
Support for legacy data migration
Support for one operation mode to another
Single user
Managerial system
Collaborative system
Support for version upgrade

8. System design (3) Determine the system environments to support
Hardware support & infrastructure (& Web-based vs. client-server)
Software support & infrastructure
Single site vs. multiple sites
Computation/database distribution and/or federation
Support for communication (means) and interface (to 3rd party systems)
Determine the application functionality to support

9. System design (4)
Specify default application functionality for each operation mode
Design the overall system architecture
Design for the system configuration and management module
Design the detailed functionality for the business process/workflow design module.
Work (de-) composition & planning
Scheduling
Schedule control & sequencing
Cost control
Quality control
Reporting (& communications)
Viewing

10. System design (5)
Design for the functionality for process components definition
Generic, basic business activity
Generic resource capability
Generic work structure and element
Design for the system’s user interface
Forms & flows design
Messages design
Online “i” & search design
Design for the system’s database (tables)
Design for default settings (of modules/processes/parameters) for each operation mode

11. System implementation (selection)
Determine implementation environment & tools (for coding, validation, and management)
Establish a collaborative R&D environment for changes management and version control
Set up guidelines for code structure, user interface design, and documentation
Establish standard libraries and inventory of system vocabulary, terminology, abbreviations, components (of different levels) for consistency and efficiency.
Establish a test policy and a library of test cases for automatic testing

12. Deployment design Deployment strategy design
Breadth first vs. depth first
System modeling & analysis process design
Fixed procedure and forms for each mode
Installation process design
Automatic vs. manual
Upgrades
Training process design
Design of user cases
Training programming (top down vs. bottom-up)
Online training
Data migration/entry process design
Validation and switch-over design
Parallel vs. ?
Systems interface (integration)
Intermediate tables
Direct access to database
