Enterprise Resource Planning systems implementation process

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.

Information Technology Infrastructure Factors ATP execution requires information like customer orders, resource availability, production processes, inventory, etc. from supply chain business systems. The ATP execution mode is directly affected by the information retrieval speed. Hence, IT infrastructure and production information systems like enterprise resource planning (ERP), manufacturing execution system (MBS) and legacy systems are essential to the successful implementation of an ATP strategy. Moreover, ATP outputs also... 

Level 5 of IT introduces a full network communication system with a shared architecture that integrates planning across the value chain. Extended enterprise architecture is in place. Strategy and implementation resources are extended across the value chain. Internet tools are the dominant technology infrastructure. Processes and standards extend across the network.
