Our Paper Deals on the Topic of 'Intelligent Information Retrieval'. There Are Many Processes For Extracting Knowledge Form a Complete Information System. As Observed, In Many Cases, Real Jo Problems Are Uncertain; Ire May Categorize Such Problem Under the Incomplete Information System. It Is Difficult to Deal With Those Systems Having Knowledge Having 'Incompleteness' (Some Values In Dataset Is Missing) and 'Inconsistencies' (Ambiguities and Contradicting Values In Dataset) In Nature. Hence, the Process of Knowledge and Information Extraction Becomes More Challenging Where Real Time Data Are Incomplete. Rough Set Can Be Used As a Tool For Clustering and Handling Incomplete Information. In This Paper We Have Defined and Discussed on some of the Known Properties of Rough Set and We Have Implemented the Tool to Generate Information For a Software Engineering Process. Planning For Delivery and Installation For any Software Requires', Burning For Procurement of Hardware, Software, and Skilled Manpower (Software Developers). the Process of Delivering the Software Also Consists of Preparing the Documentation and Manuals, and Planning For Training. Scheduling For Delivery and Installation Within the Deadline and Estimated Coast, on the Other Hand, Requires the Preparation of a Time Table For Putting the System In Place. It Is Desirable In Many Cases, That the New Software Is Installed While the Old System Still Operates, As the Automation System Need to Be Running. We Have Studied a ...
