Walkthrough:
1. Start with department policies, procedures and flowchart/ narratives. 2. Make sure you understand the flows of transactions or the protocols as documented in the department policies, procedures and flowchart/ narratives. 3.

Sign off the workpaper once you complete your testing and documentation.
