  7. 7. 4 Cost Effectiveness <ul><li>Challenge public sector norms: </li></ul><ul><ul><li>Must be universally accessible </li></ul></ul><ul><ul><li>Must work on all platforms </li></ul></ul><ul><ul><li>Must work on legacy systems </li></ul></ul><ul><ul><li>Must be managed in-house </li></ul></ul><ul><li>Tell me: </li></ul><ul><ul><li>Why? </li></ul></ul><ul><ul><li>Does the best drive out the good? </li></ul></ul><ul><ul><li>Don’t you encounter the ‘IT Services barrier’ (Skype is evil, doesn’t use the right standards,…) </li></ul></ul>Assertions Have you costed Amazon S3 and EC2 (e.g. 2-click installation of Moodle for $9/month)?

  10. 10. Summary <ul><li>What if: </li></ul><ul><ul><li>The VLE is dying? </li></ul></ul><ul><ul><li>Flickr & Facebook define students expectations for social networks? </li></ul></ul><ul><ul><li>The lightweight stuff wins over the masses; the slow-moving worthy stuff doesn’t get used? </li></ul></ul><ul><ul><li>Out-sourcing the infrastructure delivers benefits to the institution (cost-savings) and users (richer functionality (cf. TCD and Google Mail) </li></ul></ul><ul><ul><li>Web 2.0 today is like student life in 1960s </li></ul></ul><ul><ul><li>Everything I have said is completely wrong! </li></ul></ul>Will your project fit in with a changed environment? Will it have the flexibility to respond to possible changes?
