The use of electronic means to enhance the management of the procurement process is one of the central components of Public sector reform due to its potential impact on public sector efficiency and effectiveness, on the institutional reorganization process, on businesses´ productivity and competition levels and on the level of trust form the public. The main difficulty in implementing e-GP lies on knowing how to start, and the stages to be followed. Several countries have already developed their own e-GP processes, under various models, achieving different degrees of success. These experiences have provided several key components to be taken into account in order to develop a successful e-GP process. These are the components used to build this Roadmap. Characteristics of this e-GP Roadmap are as follows: it can be applied in all countries, regions, and municipalities. This roadmap serves as a baseline for the creation of a more specific one
and it is based on the fact that the role played by e-GP in the modernization of public sector processes encompasses a combination of institutional changes, political decision-making, legal and regulatory development, selection and implementation of standards, trade promotion, human resources development, computer science and the private sector involvement. It therefore, does not focus only on administrative or technological issues, and does not promote 'plug and play' solutions, because of their lack of ability for promoting structural changes and the limited of their effects.
