With the advent of technology and access to information, society is demanding more from those in power when it comes to providing quality public services. Today, with the new vision of public service provision, taxpayers need to be treated as customers of these services, and their counter-parties are needed in return for taxes that are increasingly efficient and of superior quality. In any area of public services, society is looking for an improvement in the way they are provided. Taxes are increasingly being monitored by a large proportion of those who no longer want to participate as a passive party, i.e. just be good payers, but now see themselves as "customers", and privatisations, concessions and public-private partnerships can alleviate these symptoms of poor management in which public administration suffers in the country. The citizen is the protagonist and watchdog of this model of public service management, where it materialises in better results in the provision of services to society as a whole, whether they are large-scale such as roads, railways etc. or small daily demands such as issuing personal documents, a well-structured and supervised public-private partnership can help.
