Free Open Source Software Solutions
Open Source software provides low cost, high value software following open standards.
This software can be peer reviewed to achieve better quality and reliability without vendor lock in.
Open standards allow documents to interact effectively across applications.
Open Source Software Advantages
- Cut operating costs for software and licences.
- Scale to software requirement changes quickly.
- Scale up virtual computing environments with less licencing issues.
- Less issue with product versions not being backward compatible.
- Lower hardware requirements in most cases.
Open Source Software Disadvantages
- Product upgrades may be a manual process in some cases
- Training staff to work with new applications
- Conversion of document types may be required

Open Source Implementation Considerations
- Desktop hardware with Linux appear to be approximately $300 US cheaper that Microsoft Windows 7 Professional.
- A further saving of $230 US can be made by using Open Office instead of Microsoft Office.
- Compare the cost of Cloud Servers version local physical servers.
- Consider if local server consolidation using virtualisation may improve local server utilization, reduce space needed, reduce power needs and reduce cooling needs.
- Can specialized application be provided using Software as a Service model?
- What Open Source Software can run under Windows Operating System? https://www.theopendisc.com/
- Can older hardware or thin client hardware be used with virtual desktop to reduce or eliminate desktop hardware upgrade cycles?
- Chromebooks look like a laptop and run a Chrome browser. They come with Google Docs and do not need antivirus. Cloud applications and web applications can also be used. Cheaper laptop.
