The establishment of an information system allows decision at once to make optimal production indicators and dashboards, for example by reducing the time spent on unnecessary tasks such as re-keying of data, and make more reliable and more efficient analysis of these data, taking into account in particular the history of developments and decompartmenting analyzes. It remains true that, in the future, a major challenge is faced in the design and implementation of a ERP is to enable employees to have indicators, even complex, near real-time . It is therefore to design analysis solutions to accelerate significantly the processing time, even though the data to be mobilized are more important and that the architecture of multi-dimensional databases is more and more complex. Analysis technologies in memory currently used by many publishers already provide an answer to this requirement. They provide for the possibility to store information directly in RAM rather than on the hard disk including the use of compression techniques, which induces gains considerable response time.
Discussion
The first step is the study and definition of needs of the client (Ballet Star Shoes). This is probably the most important phase since it is understood that the Ballet Star Shoes expects its ERP and write documents that will specifications for its realization. Every project is different, of course: the architecture of the ERP and the decision process even vary from one project to another by comparing one hand, the level of existing equipment with the level of equipment required and secondly following user needs expressed.
After identifying the different groups of actors involved in the implementation of the ERP, it is first necessary to conduct interviews with employees to clarify their needs.
Once these requirements have been clarified, the contractor can then study the existing SI, keeping in mind what employees need. Insofar companies stack different environments and their information systems often takes the appearance of a mille-feuille of heterogeneous applications, it is particularly essential to the balance of the whole architecture and existing applications, especially infrastructure (servers, storage, networks) by identifying their strengths and limitations, for later, simplifying the overall operation including removing duplicates. It is also to do everything possible to keep the data already collected by the company and to ensure that during the implementation of decisional information system, the data will not be altered, corrupted or simply deleted (Barley, 1983, pp. 402).
Once the needs assessment is carried out, defined the functional and technical specifications. More precisely, from the functional specifications defined by the assistant project manager (Ballet Star Shoes), the contractor (Ballet Star Shoes) wrote the first detailed functional specifications for translating functional requirements precisely, technical and organizational considerations: it concerns data and treatments but also provide employees with the user interface: models, screens, reports, web screens, etc. These functional specifications are of great interest for the Ballet Star Shoes to the extent that they allow him to explicitly validate the understanding of the need Ballet Star ...
