The use of electronic means to enhancethe management of the procurement process is one of thecentral components of Public sector reform due to itspotential impact on public sector efficiency andeffectiveness, on the institutional reorganization process,on businesses´ productivity and competition levels and onthe level of trust form the public. The main difficulty inimplementing e-GP lies on knowing how to start, and thestages to be followed. Several countries have alreadydeveloped their own e-GP processes, under various models,achieving different degrees of success. These experienceshave provided several key components to be taken intoaccount in order to develop a successful e-GP process. Theseare the components used to build this Roadmap.Characteristics of this e-GP Roadmap are as follows: it canbe applied in all countries, regions, and municipalities.This roadmap serves as a baseline for the creation of a morespecific one; and it is based on the fact that the roleplayed by e-GP in the modernization of public sectorprocesses encompasses a combination of institutionalchanges, political decision-making, legal and regulatorydevelopment, selection and implementation of standards,trade promotion, human resources development, computerscience and the private sector involvement. It therefore,does not focus only on administrative or technologicalissues, and does not promote 'plug and play'solutions, because of their lack of ability for promotingstructural changes and the limited of their effects.
