This research explores the drivers behind the implementation of performance measurement systems (PMSs) in Indonesian local government (ILG). It analytically assesses Indonesia's attempt to introduce a PMS by addressing three research questions: RQ1) Do organisations in developing countries actually use PMSs to aid decision-making and help plan for future performance improvement? RQ2) Do the three isomorphic pressures exist in the development and use of PMSs? and RQ3) If institutional isomorphism is evident, can accountability exist within the development and use of PMSs given these pressures. Design To assist in answering the research question, both closed and open-ended interview questions were developed. The questions were structured under four headingsaccountability, performance measurement, institutional isomorphism and others. In-depth interviews were conducted in 2010 with 24 Indonesian local governments targeted using purposive sampling. Both types of local government (regional and municipal) and both localities (Java and non-Java) were represented. A cross-section of participants ensured a range of responses from low-level officials to high-level managers in functions including administrative, finance, planning and audit, were obtained. Findings Results determined that although employees perceived coercive isomorphism as being a driver of ILG compliance with LAKIP, many councils were still not reporting and those that were, were not doing it well. Many councils lacked management motivation with some choosing to merely mimic (mimetic isomorphism) what others were doing. Better-resourced councils made use of external consultants or local universities where knowledge was shared (normative isomorphism). Practical implications An understanding of factors influencing the development and use of performance measures, in turn, can be used not only to improve PMSs in the future but to improve the quantity and quality of LAKIP reporting. Originality / Value The theoretical development and interpretation of this research is drawn from institutional theory with a major contribution being that it provides an in-depth conceptual overview and understanding of factors influencing the development and use of performance measures. Further, it fills a gap in the literature exploring PMSs and accountability in a developing countryin this case, Indonesia.
