Enterprise Resource Planning systems system functions

A hierarchy of systems can be considered to consist of OCS, MBS, and Enterprise Resource Planning (ERP) systems (Figure 6.1). The issue of where individual systems implement particular functions in the hierarchy becomes blurred. As applications become more distributed, the ability to interchange data in a simple, low cost and validatable manner will become even more important. Open applications will therefore cover applications ranging across these three layers. 

The last group encompasses standard software systems, such as enterprise resource planning (ERP) systems like those from SAP, Baan, or Oracle. ERP systems offer greater flexibility with respect to customization, provide support for data management, and include functionality for creating and managing a (sub)repository. The main weakness is in active analysis of business structures—that is, ERP tools typically do not offer tools for simulation process alternatives. 

An enterprise resources planning system is a set of software modules that provides a company with the capability of automating the transactions involved with its business processes. The ERP system provides a common database and establishes uniform policies and practices across the entire enterprise. This allows real-time access to the data. An ERP system is an outgrowth of the traditional manufacturing software systems such as Material Requirements Planning Systems (MRPII). The traditional systems focused on planning and optimization of these plans. The ERP system expanded beyond these to serve additional functions in the firm. 

These have played an important role as enablers of various functions, as well as decision-making tools in the product life cycle. This is particularly true in the case of enterprise resource planning systems that firms have been using successfully to integrate actions and policies across functions and entities in an enterprise. The problem, however, arises whenever newer functions are introduced into the enterprise, especially when various parts or entities of the system are either not ready or incapable of integration due to various reasons, primarily lack of technological capabilities.

IS refers to the software packages and databases that provide the functionality to implement the business processes. These include such packages as Enterprise Resource Planning (ERP), Manufacturing Execution Systems (MES), Electronic Document Management Systems (EDMS) and Maintenance Management Systems. 

In the evolution of supply chain management, the first horizontal processes were transactional. They were billing systems created to automate the order-to-cash and procure-to-pay processes. These systems of record were implemented using standard out of the box functionality in enterprise resource planning. However, for these new horizontal processes, there is no standard out of the box system for implementation. 

Enterprise Resource Planning (ERP) ERP systems are comprised of software programs that tie together all of an enterprise s various functions — such as finance, manufacturing, sales, distribution, procurement, and human resources. This software also provides for the analysis of the data from these areas to plan production, forecast sales, and analyze quality.

Table 2 shows the nature of the data usage by the MBS functions. The numbers in each ceU correspond to the numbers assigned above. The designations HRM, ERP, and PPE refer to non-MES systems of the enterprise that use some of the same data.
