ERP is complex. You need a team that is knowledgeable, works with you to develope the master plan, is easy to work with and keeps focus and accountability throughout execution.
Support
Capable personnel that knows your environment, business processes, and unique business goals will give you the confidence that, when a problem arises, it will be resolved. You need a help desk that not only solves a system issue, but can also discuss possible business process optimizations or suggest a new way of looking at how things are done.
Since the world is constantly changing, supporting systems that interact with the world require continuous adjustments. Having a quality support team ready to assist is crucial.
