The Importance of a Human Resource Department
Every organization requires a set of functional as well as behavioral competencies to achieve its business goals. For some organizations, especially startups, the need for functional competencies might far outweigh the behavioral ones at that point in their growth cycle. As a result, they might decide to do away with the HR Department entirely, as most of the strategic and tactical work is done by the founding members themselves. Any transactional work, such as payroll administration or contractual hiring, can easily be handled by line managers or outsourced.
However, as organizations grow in size and scale of operations, it becomes logical to have a dedicated department to ensure that employees display the essential behaviors desired by the organization. For example, in a retail chain, this could mean customer responsiveness, while in a consulting firm, it might mean problem-solving intent. In other words, the HR department ensures that individual capabilities are utilized effectively to meet current and future business needs.
Attaining cohesiveness of culture and capability building in the organization are two important long-term objectives that may be compromised if all HR work is handled by line managers due to an increased focus on short-term results.
Besides this, there are some highly specialized HR functions, such as employment law and compensation management, for which a dedicated HR professional is necessary.
Hope the above reasons might be of some help.
