Answer by taking a quote from the following article:

Ban Ki-moon (; Hangul: bangimun; Hanja: Pan Ji Wen ; Korean pronunciation: [pan.gi.mun]; born 13 June 1944) is a South Korean diplomat who was the eighth Secretary-General of the United Nations from January 2007 to December 2016. Before becoming Secretary-General, Ban was a career diplomat in South Korea's Ministry of Foreign Affairs and in the United Nations. He entered diplomatic service the year he graduated from university, accepting his first post in New Delhi, India.

In early January, Ban appointed the key members of his cabinet. As his Deputy Secretary-General, he selected Tanzanian foreign minister and professor Asha-Rose Migiro, a move that pleased African diplomats who had concerns of losing power without Annan in office.  The top position devoted exclusively to management, Under-Secretary-General for Management, was filled by Alicia Barcena Ibarra of Mexico. Barcena was considered a UN insider, having previously served as Annan's chief of staff. Her appointment was seen by critics as an indication that Ban would not make dramatic changes to UN bureaucracy. Ban appointed Sir John Holmes, the British Ambassador to France, as Under-Secretary-General for humanitarian affairs and coordinator of emergency relief.  Ban initially said that he would delay making other appointments until his first round of reforms were approved, yet later abandoned this idea after receiving criticism. In February he continued with appointments, selecting B. Lynn Pascoe, the U.S. ambassador to Indonesia, to become Under-Secretary-General for political affairs. Jean-Marie Guehenno, a French diplomat, who had served as Under-Secretary-General for peacekeeping operations under Annan, remained in office. Ban selected Vijay K. Nambiar as his chief of staff.  The appointment of many women to top jobs was seen as fulfilling a campaign promise Ban had made to increase the role of women in the United Nations. During Ban's first year as Secretary-General, more top jobs were being handled by women than ever before. Though not appointed by Ban, the president of the General Assembly, Haya Rashed Al-Khalifa, is only the third woman to hold this position in United Nations history.
