Status Quo of Software Development

• Proprietary software
• Consumer driven
• Clear commercial model
• Open source software (Movement)
• Consumer developer driven
• Unclear goals
• Stability of the status quo
• Long-term profits
• Short-term profits
• Dependencies
• Commercial funding of open source MS Perl IBM
  100 million
• Open source contributions RedHats usage of
  packages

Software Development

• Open source development
• Cathedral and the Bazaar
• Open community encourages new ideas
• Lack of reliable labor and resources
• Commercial development
• Slower to innovate
• Consumer driven development
• Meeting world expectations
• Roles of software development
• Niche software development Open source
• Profit driven Proprietary
• Consumer education (TCO)

5
TCO Total Cost of Ownership

• Direct cost of ownership
• Usability (Easy of use)
• Initial product cost
• Indirect cost of ownership
• Maintenance
• Support
• Balancing direct and indirect costs
• Lowering cost of total ownership

6
Shift of Development Model

• Retraining
• Re-introduction of new software
• Bugs
• Reliability
• Stability
• Integration with other Software Suites
• Software Scalability
• Meet requirements of previous software
• Open source development doesnt always scale
• Open source is usually built around new instead
  of stable

Requirements for Transition

• Compatibility
• Software compatibility
• Hardware compatibility
• Consumer acceptance
• Interface
• Workflow
• Bugs
• Open source community acceptance
• Continual support for open development

Transitioning from a Closed to Open Source Model

• Pre-Transition
• Requirements gathering
• Consumers
• Developers
• Transition
• Development compatibility
• Consumer compatibility
• Post-Transition
• Long-term integration
