The Board of Commissioners and the Board of Directors, which are Top Management Teams (TMT) are essential resources for organizations in building organizational performance. One of the factors of the TMT that was considered necessary was the diversity of the TMT members. The composition of the Board of Commissioners and the Board of Directors is a crucial part that shapes their abilities and impacts on the company's performance. From the existing studies, it turns out that the impact of TMT composition on performance produces mixed results and is considered to be still confusing, so it still needs further investigation. This research was conducted in the context of the banking industry and used operational performance as a direct impact of TMT diversity, as well as its direct impact on the bottom line (ROA and ROE). The data used is the Indonesian Commercial Bank in BUKU 3 & 4 categories, which is categorization of Commercial Banks based on business activity grouping (Bank Umum Kelompok Usaha or BUKU, hereafter). The period used is five years, namely from 2013-2017. The safety of TMT used is Gender diversity. The operational performance used is Non Performing Loans (NPL), Operating Income Operating Costs (BOPO), Net Interest Margin (NIM), Outstanding Loans and Outstanding Third Party Funds. Testing models using SEM with the Smart PLS 3.0 application. The results showed that gender diversity reduced Outstanding Loans and Outstanding Third Party Funds and BOPO. Gender diversity does not significantly affect NPL and NIM and ROA and ROE. The factors that influence ROE are NPL, BOPO and outstanding loan, while the factors that influence ROA are NIM and BOPO.
