Benefit Maximization Of Legacy Web Page Application Using Client Side Web Page Modification

Providing a service can be different depending on servant's experiences, cultures, environments and resources. Software has been designed and developed to fit requirements to support the service provisions. Presently deployed software is typically effective for only services under specific situations. This matter affects user acceptance and becomes an important limitation in widely spread software utilization and maximizing benefits from ICT investment. Presently mostly deployed software systems were developed using web page technology. Software has been designed to broadly cover all core business and data entries required by the service. Data entry web page typically includes text input fields, selection fields of multiple choices and so on. However in some contexts data value can be set by default internally without the need of human typing. In some contexts too many multiple choices make data entry inefficient. In order to contextualize software to fit various contexts, the software modification is required. In this paper we propose a technique of client side web page modification to maximizing benefit from legacy web page software. This method enables existing software systems be modified easier, faster and cheaper to maximize benefit without modification of the web server programs. Experiments have been performed with legacy web applications of government bodies in Thailand. The result indicates that benefit can be increased significantly from existing web application without modification of web server.
