What do you think that ERP implementation is a challenging task?

There are few information systems whose design and implementation challenge an organization like enterprise resource planning (ERP). Done right, a new ERP implementation can dramatically improve business processes. But when an implementation fails huge amounts of money and effort could be misspent.

It is important to be aware of how ERP as a technology evolved, what its strengths and weaknesses are and the nature of important implementation challenges. Further, understanding of how ERP and legacy system metadata can be used to simplify implementation and help organizations best plan for this exciting new challenge.

ERP solutions provide integrated applications that access standardized enterprise data - replacing the unorganized legacy system. Following are the some of the challenges to a successful ERP implementation.

• Inadequate definition of requirements
• Resistance to Change
• Inadequate Resources
• Inadequate Training and Education
• Lack of Top Management support
• Unrealistic expectations of benefits and ROI
• Miscalculation of time and effort
• Poor communications
• Software business process incompatibility
• Poor project design and management
• Poor ERP package selection

I think that requirements specification is the most challenging task. following that is the ERP selection process. Following that is defining the project success.
