  Remove the unnecessary start events.
  Consolidate the logic of the multiple start events into a single start event if applicable.
  
  
  
  Validate the Process Model: After making changes, validate the process model to ensure that it is correctly configured and does not contain any errors.
  
  
  Re-deploy the Process Model: Once the changes are made and validated, re-deploy the process model to the system.
  
  
  Test the Process: After deployment, test the process to ensure that it starts correctly and behaves as expected.
