The term performance has been defined with efficiency and effectiveness, because
effectiveness illustrates degree of attaining the purposes and efficiency refers to the fact that
how resources have been used to achieve purposes. They can be regarded as two important
aspects of performance, i.e. there can be both internal reasons (efficiency) and external
reasons (effectiveness) for special sections of performance. Thus, performance is a function
of efficiency and effectiveness of activities (Cruss & Lunch, 1991).
