2. Overview ● Introduction: “What is SimMetrics?” ● Review of Software Metrics ● Related Software: DataDrill, MindManager ● SimMetrics GUI ● Future Work ● Questions/Answers

3. Introduction SimMetrics is a tool designed for software project managers Creates PowerPoint presentations from data in Excel spreadsheets Used to generate informative visual representations of software metrics data Generic interface design will allow for program extensibility

4. What Are Software Metrics? Measurable factors related to the development of software Help indicate potential problems in the development process Used by project managers to produce quality software in a timely manner Defining new, more informative metrics is an active area of research

5. Categories of Metrics Schedule Performance and Confidence –Functional Delivery Progress –Test Progress –Integration Progress –Milestone Migration –Defect Resolution –Defect Aging Risks –Top Software Risks –Software Risks on Programs Critical Path –Staffing Forecast –Requirements Progress –CPU / Memory Utilization –Speed of Execution Earned Value –Specific Earned Value –Specific Estimated at Completion

6. Examples of Software Metrics Functional Delivery Progress –Planned Delivery Date: When software functionality was initially planned to be fully tested and integrated. –Re-Planned Delivery Date: Each revised planned delivery date. –Delivered Date: When planned software functionality actually becomes available

8. Examples of Software Metrics Defect resolution –Number of defects reported –Number of reported defects that haven't been fixed Defect Aging –Number of months to repair a known defect Category 1 Defect: System Abort – Prevents accomplishment of a mission-essential capability of jeopardizes safety Category 2 Defect: System Degraded – No Work-Around. Adversely affects accomplishment of an operational or mission- essential capability for which no work around solution is known

10. DataDrill Similar concept to SimMetrics Manages software metrics Provides graphical visualizations Web interface design Data is centralized Information is shared Differs in that it is not as flexible as our concept

11. MindManager Another similar tool Used in process management and planning Features Microsoft Office integration Differs in that it does not focus completely on metrics

13. GUI Preview: Sample Configuration Window Layout defined by respective Visualization Module

14. Future Work Generate Macromedia Flash presentations as output. Generate HTML web pages as output. Provide a graphical interface for specifying new visualization modules. Voice recognition for control of the application.
