What Level does my Organization fall on the CMM

In my organization, I believe that the level they fall under on the Capability Maturity Model would be Level 3 (Process Standardization).  Process Standardization is what upper management focuses on. Our Human Resource, Accounting, IT Department, Purchasing, and Research Team all follow a standardized process.  However our Travel/Reimbursement department has been in dire need to standardize their travel and reimbursement processes. Purchase Orders were back up for months and students and Professors were not getting reimbursed in a timely fashion. The lack of a supervisor did not help either.  Upper management, myself, and the reimbursement team sat down together to figure out a standardized process to make sure all Purchase orders were process in a timely matter. In that meeting we development key requirements on what steps to follow, and what goals needed to be met. We also brought in our IT programmer to help create a more functional online system to submit, store, and keep records of the purchase orders. Other than our Travel/ Reimbursement department our organization would be considered defined. I believe that the Travel and Reimbursement Department would fall under Level 2 (Managed) for now.
