The use of computer-aided tools in any office to do tasks has made significant difference in terms of work throughput. Most computers available at present allows multiple windows to be concurrently opened. Despite the advantage it is supposed to give the users, this actually is confusing to many. While some knows how to view different windows simultaneously, most people find it difficult to shift from one window to another and vise versa. The main objective of this study is to determine whether the integration of different office application software would be beneficial to users. The researchers created an integrated OpenOffice application wherein Writer, Calc, and Impress applications have been rolled into one. The application only runs in Windows XP, Vista and 7 operating systems. In the course of the study, the researchers used descriptive research method and were guided by iterative/incremental model in the development of the application. The test conducted revealed that with the integrated OpenOffice application, the time consumed in opening several windows was reduced significantly.
