Answer:
In the restaurant business, self inspections can help you ensure that the food is always safe for your customers (better quality food) , lower the overall costs of the restaurant and helps to increase your reputation (a clean restaurant is always seen as a better restaurant).
Self inspection doesn't mean that the manager herself has to carry out the inspection, another employee can. Self inspection refers to making sure you comply with all regulations without having an inspector come and evaluate your restaurant. Self inspections will help the restaurant get higher inspection scores, and that was one of Brianna's major accomplishments.
