### Gap Analysis  
If the mapping procedure shows where and how Level(s) is present at the BRS, complementarily, the gap analysis aims at finding where and how the BRS miss Level(s) and what can they do to reconnect. Doing this would increase conformity, as was presented to the BRS managers. Regarding indicators with a deviation, the following options were recommended accordingly: (a) suggestions concerning further developments of the Level(s) framework; (b) possible conversion of the data submitted in the BRS certification process to be adapted into Level(s) procedures; and (c) adjustments to the BRS to comply with Level(s). Some general recommendations were also identified, including adjusting LC \begin{table}
