ERP Systems

An ERP system is a complex or a multitude of communicating application software or IT systems used to support the resource planning of the entire enterprise. Complex ERP systems are often divided into sub-systems (application modules), which can be combined with each other depending on the company’s needs.

ERP systems differ mainly

(Industry: steel industry, automotive industry, chemical industry, …, services: trade, insurance, banking, health care, …),

According to the scalability to different company sizes (number of required users or company locations),
In the offered scope of functions to be supported (production, material management, sales, …)
And in the technologies used (databases, programming languages, layer architectures, operating systems, etc.).
The trend can be observed that more and more providers are betting on web-based products. For example, the system interface is displayed in a browser window. This allows, among other things, the possibility to implement enterprise-specific access to your own system without having to install a graphical user interface. Thus, for example, suppliers or customers can be directly involved in the business processes, for example, to place orders, to terminate deliveries, etc. These options represent a significant time advantage and thus a cost advantage.

The approach of looking beyond the company’s boundaries is the basic idea behind ERP-II systems. It is also the core of service-oriented architectures.

Basically, the demand is determined by the available ERP vendors. A large company must also be able to map its group structures via an ERP solution, if necessary, directly integrate subsidiaries (mandantenfähigkeit) and needs a variety of complex, business management functions. Despite the use of standard software, consultancy and customization (customizing) cause greater introduction costs. In contrast, when using such a solution, for example, SAP ERP or Oracle E-Business Suite, a compact approach model is to be selected for a small or medium-sized company (SME) in the introductory project and the adaptation must be restricted to the essential requirements. In addition to complex, highly integrated and multi-sectoral, universal ERP systems, an SME also provides branch-specific ERP systems with reduced complexity and functionality.
