The typical audit includes the following phases:
Phase 1: Planning
This phase is performed in advance of the on-site work and usually does not require substantial departmental involvement. Audit staff reviews any past audit work, information on the area selected for audit, and statistical or financial information. Auditors also prepare the audit program, which lays out a roadmap for how and when the audit will be conducted.
Phase 2: Audit Entrance Meeting/ Preliminary Audit Survey
A formal audit entrance meeting is held to introduce the audit team and discuss the upcoming audit work and audit process. During this meeting, management can request any additional areas that they would like to see reviewed as part of the audit. Timeframes for audit steps, objectives, and logistics (facilities, availability of personnel, primary contacts, etc.) are established at this time. Auditors gather information and enhance understanding of key business processes by conducting interviews, observing departmental procedures, performing process walkthroughs and flowcharting processes. Results of the work done during this phase determines the amount of additional testing to be performed
Phase 3: Fieldwork and Testing
Fieldwork may include testing transactions, procedures, administrative or managerial functions, automated systems or technology used, and various other areas specific to each department/business process audited. This is the longest phase of the audit and normally takes up about fifty percent of the audit time budget. If the auditors find anything during testing that may be included in a report, it is analyzed and discussed with staff/ management of the area under review to ensure that all information necessary to understand the item is obtained to avoid inaccurate conclusions.
Phase 4: Reporting
Upon conclusion of the fieldwork, internal auditors prepare a draft report for the department director to review and respond. Responses should be brief and limited to the observations. All responses must include the following:
- Concur or Do not concur: Departments should indicate “Concur” if they agree with the audit observation that there is an area that needs to be corrected, or “Do not concur” if they do not agree that any correction is necessary and provide further explanation. “Do not concur” responses are extremely rare, as the parties normally strive to reach consensus during the fieldwork phase.
- Action to be taken: This must state specifically how the observation will be addressed.
- Estimated Completion Date: This answer must contain a month, day and year that the observation is expected to be addressed. It is management’s best estimate of completion date at the audit report date and may be changed on later updates.
Once audit responses are reviewed, approved and incorporated into the report, the final audit report is distributed to management and the City Commission. Final reports are public records and are posted on the Internal Audit web page.
Phase 5: Follow-up
Depending on the nature of the audit or the audit findings, a follow-up audit or other limited review may be scheduled at a future date.
