经理 (jīnglǐ) is the general word for a manager in a business or company. It differs from 主任 (zhǔrèn), which is the head of a department or office (often in government/institutions), and from 主管 (zhǔguǎn), which emphasizes being 'in charge of' a specific area or project. In most work situations, 经理 is the standard term.
