relationship between the two. Under NPM, public managers have incentive-based motivation such as pay-for-performance, and clear performance targets are often set, which are assessed by using performance evaluations. As well, managers in an NPM paradigm may have greater discretion and freedom as to how they go about achieving the goals set for them. This NPM approach is contrasted with the traditional public administration model, in which institutional decision-making, policy-making and public service delivery is guided by regulations, legislation and administrative procedures. NPM reforms use approaches such as disaggregation, customer satisfaction initiatives, customer service efforts, applying an entrepreneurial spirit to public service, and introducing innovations. The NPM system allows "the expert manager to have a greater discretion". "Public Managers under the New Public Management reforms can provide a range of choices from which customers can choose, including the right to opt out of the service delivery system completely". Evolution The first practices of New Public Management emerged in the United Kingdom under the leadership of Prime Minister Margaret Thatcher. Thatcher played the functional role of “policy entrepreneur" and the official role of prime minister. Thatcher drove changes in public management policy in such areas as organizational methods, civil service, labor relations, expenditure planning, financial management, audit, evaluation, and procurement. Thatcher's successor, John Major, kept public management policy on the agenda of the Conservative government, leading to the implementation of the Next Steps Initiative. Major also launched the programs of the Citizens Charter Initiative, Competing for Quality, Resource Accounting and Budgeting, and the Private Finance Initiative. A term was coined in the late 1980s to denote a new (or renewed) focus on the importance of management and 'production engineering' in public service delivery, which often linked to doctrines of economic rationalism (Hood 1989, Pollitt 1993). During this timeframe public management became an active area of policy-making in numerous other countries, notably in New Zealand, Australia, and Sweden. At the same time, Organisation for Economic Co-operation and Development (OECD) established its Public Management Committee and Secretariat (PUMA), conferring to public management the status normally accorded more conventional domains of policy. In the 1990s, public management was a major item on President Clinton's agenda. Early policy actions of the Clinton administration included launching the National Partnership and signing into law the Government Performance and Results Act. Currently there are few indications that public management issues will vanish from governmental policy agendas. A recent study
