Enterprise resource planning (ERP) systems are highly complex information systems.

The implementation of these systems is a difficult and high cost proposition that places tremendous demands on corporate time and resources.

Organizations need to understand the system adoption from the user's perspective to prepare their employees to face new challenges and learn how to make good use of the technology to reap tangible benefits ().

Indian organizations have been exposed to advanced use of information technology (IT) in organizations that are made possible through joint ventures and technology transfer initiatives which in turn were facilitated by increased international trade and commerce.

Enterprise resource planning systems are extensive software systems that integrate a number of business processes, such as manufacturing, supply chain, sales, finance, human resources, budgeting, and customer service activities ().

The other benefits of ERP systems are its complete integration with all the business processes, reduction in the volume of data entry, upgradability of the technology, portability to other systems, adaptability, and applying best practices ().

Complex information systems like the ERP integrate the data of all business areas within the organization.

The implementation of ERP is a difficult process as it involves different types of end users.
