Before taking decision one sided, you have to become more perceptive and should review following approaches.
If you want to think this question because of you want to make your career in one of them, then don’t make importance as one of main determinant to choose any one of them. Try to understand, there are also other factors which may affect your career. Suppose, if you are habitual to watch business news, financial updates and other finance news. Then, this attitude shows your interest in Finance. Hence there will be no benefit to enter other field Hr. or even entering in Marketing. Concentrate on career or niche which you love. This field will be surely most important.
Organization respects on those officers who perform well. If you will perform well in finance, you will be most important people in Finance. If you will perform well in human resource management, you will be most important person in Hr. It is most important to know that organization is just link between people and resources. Finance as well as Hr. people have to accomplish one target of organization. So both are two part of one coin of organization.
If we verify the job duties, we get some common point between both. Suppose one of finance officer’s duty is to maintain the salary record of all employees of company. On the other side, Hr. officer uses these data for analysis for employees’ promotion, merit rating, job analysis and other compensational plans. Finance department’s all need of employee is fulfilled by Hr. department and Hr. department’s are need of financial record is fulfilled by Finance department. So, both are doing job for fulfill their own needs. You can get idea from this approach that both are the jobs and set of duties which they have to fulfill because authorities are delegated to them. So, consider both significant.
