Do you know the concept of square pegs in round holes? Well, that's a mistake that regular people can afford to make in their local planning committee for an annual festival. In a small company, it leads to a loss of efficiency and probably money. In a big company, its effects are more disastrous, especially when the mistake is made on multiple fronts. The concept of functional job analysis exists to prevent such outcomes.
Placing the right people in the right jobs: Along with unearthing quality candidates during every hiring process, this ranks highest in determining the success of a company/organization. The process involves a thorough assessment to determine how employees perform in their roles.
Increasing organizational efficiency: When a company reaches a certain size, there is the potential for unnecessary overlapping roles and functions. This could subsequently lead to inefficiency in performing duties and allocating resources. Analyzing roles, interrelationships, and impacts could help clarify things.
