“…The literatures regarding the conceptualization and measurement of organizational performance in public sector were written by experts (Ammons 2001;Carter, Day, andKlein 1992, in Boyne 2002). Reviewing the literatures, Boyne (2002) identified "headline" of dimension of service performance: quantity of outputs (e.g., the number of surgeries performed in hospitals, hours of teaching delivered in schools, the number of houses built), quality of outputs (e.g., speed and reliability of service, courtesy of staff), efficiency (financial ratio of outputs and inputs), equity (fairness of the distribution of service costs and benefits between different groups), outcomes (e.g., percentage of pupils passing exams, percentage of hospital patients treated successfully), value for money (cost per unit of outcome), consumer satisfaction (which may be a proxy for some or all of the above, depending on the questions posed to service users). According to Zeithaml, Parasuraman & Berry (1990), there are 10 benchmarks of services, namely: tangibles, reliability, responsiveness, competence, courtesy, credibility, assurance, access, communication, and understanding.…”
