Enterprise Resource Planning systems such as Microsoft Dynamics can be configured in many ways.
Prior to Order, you will probably have issued an RFP (Request for Proposal) and had a bid process. Typically a Dynamics system might start from £200k with probably half the cost or more being for consultancy.
Once you have selected your supplier, the first stage is Systems Design, I have worked on many of these, basically, you gather information on how the business works now, right down to fine detail such as how control accounts are used and what reports are currently used, then you consider what is possible with the new ERP system, what is the best way to perform tasks, how are results reported, some of the information will be flowcharted and a route map drawn up to get from where the business is now to the new ERP system. It is a highly detailed process, my reports were typically 200 pages long and the supplier and client sign off the report before configuration work starts.
Next the system experts get to work and make a mock up of the system and then workshops are done with senior management and directors to makesure the clients instructions have been correctly intrepreted, this process is then signed off.
The next stage is Training, normally immediately before the system goes live.
If you need any help let me know.
