¶ … information technology) has opened the door for opportunities and risks. Organizations are increasingly facing competitions in the contemporary business market environment and to achieve competitive market advantages, many organizations are increasingly using ERP (Enterprise resource planning) to decline costs and offer quality products at cheaper prices. ERP is a business integration software assisting organizations to collect, manage, store as welling as interpreting data of business activities. (Vasilec, Avdejenkov, & Sosunov, 2009). Essentially, ERP integrates core of business process using a real-time database system to achieve business functions such as asset management, purchase orders, production, track business resources and share data across various departments. Assets are very critical for organizational efficiency because assets assist organizations to generate revenues to enhance stakeholder's value. However, effective asset management is very critical for organizational efficiency. To manage organizational assets, increasing number of medium and large organizations are using asset management system integrated in ERP for effective tracking of their equipments and other assets used for organizational efficiency. Despite the benefits derived from the ERP asset management systems, its implementation is challenging. To manage assets using real time system, there is a need to integrate EAM (enterprises asset management) module in ERP, however, its implementation is challenging because of its associated business rules, which may require migrating from one business to the other. Objective of this paper is to demonstrate the strategy in applying business rules to assist in automating business decision making in ERP Asset management.

Application of Business Rules to ERP Asset Management System

Business rules are relative recent in the contemporary ERP systems, however, business rules are used to improve quantitative and qualitative attributes of information systems. Since 1998, business rules are important elements of information systems. Moreover, business rules in the database engineering are similar to integrity constraints. Business rules also provide both user requirements and business process conformity. From a business perspective, business rules guide business behaviors, which support business policy as well as asserting business structure. (Chisholm, 2004). However, business rules are changing rapidly and being integrated in information systems. In ERP systems, business rules are used to automate decision making because they propagate through reengineering lifecycle from problem analysis to design. (Smaizys & Vasilecas, 2009).

However, ERP has many modules integrated in it and EAM (Enterprises Asset Management) system is one of the modules integrated in the ERP. For example, Infor Asset Management System is an equipment-tracking module that assists in tracking equipment as well as its associated costs. Typically, the EAM assists in defining assets, create equipment profiles, & records and locate equipment positions. Moreover, the EAM module assists in defining equipment records such as linear equipment, vehicles and track information associated to equipments' records. Additionally, the EAM uses meter's information to track equipment usage, which assists in identifying equipment that is due for maintenance in order to safeguard a costly equipment failure. (Infor, 2012). Similarly, Oracle EAM supports sophisticated and conditioned-based maintenance strategies for plants, property as well as public infrastructure. Typically, Oracle EAM assists in tracking equipment to eliminate obsolete spare parts from inventory to enhance safety and promote environmental standards. (Oracle, 2013). However, integrating business rules are very critical in the ERP- EAM module. The Fig 1 reveals the information flow of asset management system in the ERP modules, which will assist in creating the business rules.
