The provided data suggests several root causes for performance issues, focusing on specific process and data points:

**1. Rework Loops:**

* **Rejection by Administration/Supervisor/Pre-approver leading to resubmissions:** Several variants show a pattern of rejections followed by the employee resubmitting the declaration.  This significantly increases the overall processing time and is evident in variants with high performance values (e.g., 2542497.917, 2790977.310, 3502608.250).  This suggests a need to investigate *why* these rejections are occurring. Are there unclear guidelines, insufficient information provided initially, or systemic issues in the approval process?

**2. Involvement of Budget Owner:**

* **Longer processing time with Budget Owner approval:** Variants involving the Budget Owner generally exhibit higher performance values (e.g., 1084338.407, 2061236.516). This indicates that the Budget Owner approval step might be a bottleneck.  This could be due to the Budget Owner's workload, complex approval criteria, or delays in accessing necessary information.

**3. "Missing" Rejection:**

* **High performance values associated with "Rejected by MISSING":** Variants including "Declaration REJECTED by MISSING" have notably high performance values (e.g., 1947246.400). This suggests a problem in the "MISSING" step – perhaps difficulty in obtaining required information or unclear procedures related to this step.  Understanding the "MISSING" step is crucial for addressing this bottleneck.

**4. "SAVED" Declarations:**

* **Potential Abandonment:** While the performance value is 0 for "Declaration SAVED by EMPLOYEE," the frequency of 134 suggests potential process abandonment.  Understanding why employees are saving declarations without submitting them could reveal usability issues or process complexities that deter completion.

**5. Outlier with High Performance and Low Frequency:**

* **Investigation needed for variant with performance = 13805869.200 and frequency = 5:** This specific variant ("Declaration SUBMITTED by EMPLOYEE -> Declaration REJECTED by ADMINISTRATION") has an exceptionally high performance value despite a low frequency. This outlier warrants further investigation to determine if it represents a data anomaly or a specific scenario causing extreme delays.

**In conclusion, the data highlights rework loops (especially due to rejections), the involvement of the Budget Owner, the "MISSING" rejection step, potential process abandonment, and a specific outlier as potential areas contributing to performance issues. Further investigation into the reasons behind rejections, the efficiency of the Budget Owner's approval process, the nature of the "MISSING" step, and the outlier variant is highly recommended.**
