 Based on the provided process flows and their respective performances, here are some process and data-specific considerations that could be causing performance issues:

1. **Multiple Rejections and Resubmissions**: Many of the processes involve multiple rejections and resubmissions by the employee, administration, supervisor, or other entities. Each rejection and subsequent resubmission adds to the processing time. This is evident in flows like:
   - IEE -> ... -> Declaration REJECTED by SUPERVISOR -> ... -> Payment Handled (performance = 2936133.833)
   - Declaration SUBMITTED by EMPLOYEE -> Declaration REJECTED by ADMINISTRATION (performance = 13805869.200)
   - Declaration SUBMITTED by EMPLOYEE -> ... -> Declaration APPROVED by ADMINISTRATION -> Declaration FINAL_APPROVED by SUPERVISOR -> Payment Handled (frequency = 4, performance = 3502608.250)

2. **Involvement of Multiple Approvers**: Some processes involve multiple approvers (ADMINISTRATION, BUDGET OWNER, SUPERVISOR, PRE_APPROVER), each adding to the overall processing time. For instance:
   - Declaration SUBMITTED by EMPLOYEE -> ... -> Declaration APPROVED by BUDGET OWNER -> ... -> Payment Handled (frequency = 6, performance = 2006332.000)
   - Declaration SUBMITTED by EMPLOYEE -> ... -> Declaration APPROVED by PRE_APPROVER -> ... -> Payment Handled (frequency = 5, performance = 2249318.200)

3. **Back and Forth Between Employee and Administration/Supervisor**: There are instances where the declaration is continually rejected by the administration or supervisor and resubmitted by the employee, leading to a prolonged process. Examples include:
   - Declaration SUBMITTED by EMPLOYEE -> ... -> Declaration REJECTED by SUPERVISOR -> ... (frequency = 6, performance = 1482400.000)
   - Declaration SUBMITTED by EMPLOYEE -> ... -> Declaration APPROVED by ADMINISTRATION -> Declaration FINAL_APPROVED by SUPERVISOR -> Payment Handled (frequency = 6, performance = 2936133.833)

4. **High Performance Variance**: There's a significant variance in performance between similar processes, suggesting inconsistencies in handling time. For example:
   - Declaration SUBMITTED by EMPLOYEE -> Declaration APPROVED by ADMINISTRATION -> Declaration FINAL_APPROVED by SUPERVISOR -> Payment Handled (frequency = 4, performance = 9110508.000)
   - Compare this to the process with additional steps but lower performance: Declaration SUBMITTED by EMPLOYEE -> ... -> Declaration APPROVED by BUDGET OWNER -> ... -> Payment Handled (frequency = 4, performance = 1530125.750)

Addressing these specific points could help streamline the process and improve overall performance.
