  • Publication number: 20080126166
    Abstract: A system-design support program and method capable of visualizing costs necessary for system creation and maintenance in an easy-to-understand manner. When a function-selection receiving means receives functions selected and input, to be applied to a computer system, a resource output means refers to a resource information table which has resource information that includes the fixed cost and variable cost of each resource, to output a list of resource information related to resources available for implementing the selected functions. Next, when a resource-selection receiving means receives resources selected and input, to be employed in the computer system to be created, from the list, outputted by the resource output means, a cost output means sums up the fixed costs and variable costs of the selected resources to indicate the fixed cost and variable cost of the computer system to be created.
