The European market of management consultancy (MC) and human resources (HR) goes remarkably well as revealed by the statistics of the total amount of businesses of this sector, which amount to 61.6 billion euros at the end of 2006. It is an increase of almost 14% on the amount in 2004. The FEACO (in English: European Federation of Management Consultancy Associations), which was created in 1960, is an independent professional organization with non lucrative goal. Recently, the FEACO founded a new grid of reading of the activities carried out by the management consultancy companies. It has the role of representing and of promoting Management Consultancy profession in Europe. In the spheres of the professionals in HR, the increase in the sales turnover in the field remains partly ascribable to the actions of their federation. As for the French HR market, it follows a strong marketing policy directed towards the innovation of the services and the respect of the ethical values of the profession. So many companies try to increase their market presence as a result of the putting in place of a network offer and of creation of new services panel. The objective of this contribution is to present a study and an analysis of existing works concerning the innovating Web service in human resources consultancy. It is a question of observing new related activities to management consultancy and human resources market: training consultancy, assessment of competences, staff consultancy, management consultancy, experience validation and accompaniment. In this study we have reports of certain great sites, by their notoriety due to a true indexing work and a good marketing policy, which succeed in monopolizing a great part of the market. In opposite, very few large cabinets opt for this type of offer of on-line HR services (e-HR). The problems exposed in this study make it possible to clarify a decisional problem for an e-HR decision maker. It is a stage of thought synchronization between the watchers and the decision maker in order to be able to reformulate the problem (of the decision maker) and to lock the research stakes. This move respects the transitions between the phases of economic intelligence process. We will develop, in particular, a project which we have carried out with a French company for the construction of a strategic information system within the framework of competence management. We have developed a data warehouse design based on the process of economic intelligence (EI) and requirement analysis in decisional information.
