Questions/Answers
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
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

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

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 missionessential capability for which no work around solution is known

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

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.
