System modification is the alteration of the configuration of the system, developing new applications with an aim of improving the security of the system or boosting the efficiency of the system (Blanchard, 2004). The process reduces both maintenance and operations costs that would otherwise have increased the operating expenses.
When modifying the standard version of SAP system, it is necessary to create new data fields or use the fields that already exist in the standard system. The routine will also be affected. Personnel quantities, support and test equipment, computer resources, skill level, spares and repair parts, training, transportation and handling requirements need to be affect ted for the modification process to be successful and meaningful (Watson & Rand Corporation, 2001). Overall, the objective is to verify that the system is successfully accomplishing the intended mission. A successful modification process will make it easy for high cost or high risk areas to be identified and incorporated into the modification process as of CPPI effort (Blanchard, 2004).
Customer, operational and functional requirements are also affected as this are in the heart of every system. It has to be modified in the best way that will enhance its operation, functionality and quality of customer service. This ensures that the performance and productivity of the system is not compromised but instead enhanced (Watson & Rand Corporation, 2001). Availability requirements must also be taken into consideration.
System modification should be a regular process to improve the performance of the system. The logistics, maintenance support requirements and maintainability requirement needs to be affected so as to develop a system that will attain the required product output without incurring huge costs (Blanchard, 2004). The various requirements should be made to fit into the modification when carrying out system modification.
