As can be seen in figure 1, phased adoption has a loop in it. Every department that is to be connected to the system is going through the same process. First based on the previous training sessions security levels are set (see ITIL) In this way every unique user has its own profile which describes, which parts of the system are visible and/or usable to that specific user. Then the document and policies are documented. All processes and procedures are described in process descriptions, can be in paper or on the intranet. Then the actual conversion is depicted. As described in the above text, certain departments and or parts of an organization may be implemented in different time slots. In figure 1 that is depicted by implementing an additional module or even a total product. HRM needs different modules of an ERP system than Finance (module) or Finance may need an additional accounting software package (Product). Tuning of the system occurs to solve existing problems. After the certain department has been conversed the loop starts over, and another department or user group may be conversed. If all of the departments or organization parts are conversed and the system is totally implemented the system is officially delivered to the organization and the implementation team may be dissolved.
