Thank you for the information but please allow me to challenge you a little more in this area. Many sources speak to the symptoms that result in perceived ERP implementation failure but few speak to the root cause of these failures. The root cause has more to do with the wrong implementation strategy. Today, the majority of ERP implementations follow a traditional, ???build-from-scratch??? approach that is not adequate for implementing packaged software like ERP. What is required is an approach that addresses both the inherent advantages and challenges associated with ERP. Following are what I feel are key strategies to assist you in build the right ERP implementation strategy.
