Because it covers a wide spectrum of aspects of running a business, an ERP software system is based on some of the software products greater size and complexity in the industry. By deploying such systems in a company’s traditional methodology used to involve a group of analysts, programmers and users. This was the scheme that was used, at least until the development of the Internet. This allows our consultants have access to company computers in order to install the updated data and standardized implementation of ERP, without professional help. Such projects can become very expensive for large companies, especially multinationals. Companies specializing in ERP implementation, however, may accelerate these processes and complete the task in less than six months with a solid pilot review.At the time of making the implementation of ERP systems, companies often seek help from a supplier or vendor or ERP consulting companies. The ERP consultancy is of two types, business consulting and technical consulting. The business consulting studying current business processes of the company and evaluates its correspondence with the ERP system processes, which generally includes the customization of certain aspects of ERP systems for the needs of organizations. The technical consulting often involves programming. Most ERP vendors allow changing their software to the needs of business customers. Many of the companies seeking the implementation of an ERP make the mistake of looking for solutions at low cost, or not to hire an integrative enterprise.This type of company, not only helps in the implementation but supports them to see his client in all aspects of its business both in hardware and software change management. Some major integrated companies are EDS, Price Waterhouse Coopers, IBM, GETI or Avanade. Customizing an ERP package can be very costly and complicated, because many packages are not designed for customization, so most businesses implement their ERP systems following the best industry practices. Some ERP packages are very generic in their reports and reports, customizing those elements to do in each implementation. It is important to note that at times makes more sense to purchase report generation packages manufactured by third parties that are meant to interact directly with the ERP. Today, a good number of ERP systems have a Web interface. The advantage of this type of interface is that it requires installing a client application.While having a connection to the Internet (or local network of the company, as applicable), you can access the Web-based ERP through the typical web browser.
