Overview

A paper providing an overall description of our process engineering life cycle can be found at http://cwis.usc.edu/dept/ATRIUM/Papers/Business_Process_Modeling.ps.


Background and Definitions

Strategic Issues
  • Exploit emerging (inter)national information infrastructure for EDI/EFT/EC.
  • 
    

    Tactical Problems
    
    

    
    
    Solution:
    
    A knowledge-based distributed hypertext (KB-DHT) 
    infrastructure that supports the modeling, inter-relationship,
    integration, and accomodation of resources and people within
    local/global virtual organizations.

    Process Redesign and Evaluation

  • Process measurements and domain-independent (re)design heuristics can be used to envision a number of redesign alternatives. The following chart outlines a few of the potential redesigns for the J&A Process.
  • The development and application of domain-dependent and instance-specific measures and heuristics is expected to produce more specific redesign alternatives, such as those shown here.
  • A simulation interface screen depicting one redesign alternative for the J&A Process - R1: Joint Review Meetings, can be seen here.
  • A paper describing our approach to process measurement as the basis for guiding process redesign can be found at http://cwis.usc.edu/dept/ATRIUM/Papers/Process_Measurement.ps.
