"My last role was accountant for a small, established company. However, my predecessor did not have established procedures in place and it sounded like he had made constant mistakes. One of the first things I did when I started was I made a monthly checklist that detailed all the steps I took during the monthly close. Included in these steps were checks I performed to self-review my work. The checklist served as a cover sheet that I would hand off to my manager so that she would know exactly what steps I completed. This led to increased efficiency, as we estimated it saved four to six hours per month in error corrections."
