Process Modeling

  • Purpose
    • Understand how work involving multiple departments and roles is played in an organization
  • Description
    • Process describe as multiple persons or groups cooperate over a period of time to perform a labor
    • Involve a number of activities linked by a flow sequence, repeatable and can have many ways to complete
    • Started by an event in the field of business, actions can be taken by a person, rules or the passage of time
    • The model is a visual representation that may involve manual activities, automated or combination of both, ends when the objective or goal of the process is completed
  • Elements
    • There are several different notations, such as flow diagram and activity diagram of UML, and BPMN
    • Elements of notation
      • Activities – Steps that must be completed
      • Decisions – bifurcations where the flow…
      • Events – Outside the scope of the process, actions or messages
      • Flow – Direction of the sequence step by step of the flow
      • Paper – Type of person or group
      • Streaks and pools – Activities performed by a role
      • Endpoints – Start or end of a process or flow
    • Process improvements
      • Six Sigma, Lean and other approaches
      • Value stream mapping, analysis and statistical control, process simulation, benchmarking and other
      • Common changes:
        • Identify and remove activities that do not add value
        • Reducing the time required to complete the process
        • Improving the interfaces
        • Reduction or elimination of bottlenecks and backlogs
  • Usage Considerations
    • Advantages
      • Comfort of stakeholders with the basic elements and concepts behind the model, are effective in presenting how to handle large number of scenarios
    • Disadvantages
      • Can become complex if not structured carefully
