So, large organizations will need to consider when they have need to develop overseas markets. Their offices will have different countries' staffs to cooperate to work together. For this reason, profit and non-profit organizations need to become more diversified to remain competition. Maximizing and capitalizing on workplace diversity is an important issue for management. It brings this question: Can human resource department assist the organization's diversity development in order to let continue people to cooperate to work in order to raise performance or productivity or efficieny easily. For example, if the organization's HRD is effective, the interviewers can ensure to help their organizations to select whether what countriess' applicant whom is the most right applicant to do the departmental tasks, one China company's finance department needs one applicant who familizes US accounting/finance policy knowledge and owns US related finance and accountinr working experience to do this fiance manager position. Then, the China fiem needs to decide whether it ought to select the foreign US country's domestic applicant who owns many years of finance and accounting working experience and US accounting/finance university subject knowledge to do this finance manager position or select itself country's China domestic applicant who owns US finance/accounting related working experience and familizes US accounting/finance subjects knowledge. Although, if the China company selected the local applicant who owns finance/accounting knowledge and US company finance/accounting related working experience to do this finance manager positin. The advantages are that the finance manager and whose finance team staffs who can speak fluent chinese language. So, the finance manager and his/her finance department staffs can communicate to bring easier cooperation. But, it does not guarantee that he/she must lead or supervise his/her finance deparment staffs to raise peformance or efficiency daily. Otherwise, if the China firm select one foreign US applicant to do this finance manager position. Although, this US foreign finance manager can not speak fluent Chinese languare and he/she can only speaks American language. It is possible that the finance department staffs who all are Chinese. They can not understand English language easier. It is possible to bring communication difficult problem between the US foreign finance manager and his/her finance department staffs. But, the US foreign finance manager who has competitive effort is that his/her local US finance/accounting related working experience and university graduation of finance/accounting subject knowledge is better to compare to all China applicants whose own similar accounting/finance knowlege and related working experience in China. It seems that the foreign US finance manager applicant can perform more excellent to compare all China domestic finance manager applicants. If the finance manager's duty needs to familiarize US acocunting/finance policy to calculate tax and profit for US government tax department, due to this firm needs to sell products to US market often. It is possible that the foreign US finance manager applicant can lead or supervise whose finance department staffs to raise efficiency to work more easily, due to his/her familiar US accounting/finance policy and working experience is useful more than the China local applicants who owns more China accounting/finance knowledge and China accounting/finance related working experience.
