In (i) described above, ahead of the drafting of the installation plan, the following two requirements are considered: migration requirements that outline how installation into the production environment and system migration is implemented; and installation requirements that outline points of note in data preservation (e.g., backups), impacts on business operations, and others, and how the installation schedule and installation structure is set. On the basis of the results, the acquirer must be supported in drafting a feasible installation plan, according to installation acceptance/rejection criteria. In actual system installation described in (ii), the initialization of the system, software, and database is performed and the execution environment is prepared according to procedures defined in the installation plan, and after that, the system is installed. Ideally speaking, these installation operations are to be performed under the leadership of the user department and system operations department of the acquirer, with the supplier providing user support.
