  8. 8. What is good with OpenSource? • Good quality code = works better • Lots of developers with experience • Easier to integrate, you can change anything • Better support! • Eco-system with communities • Often loads of add-ons/plugins available for easy extension of functionality • Frequent updates
  9. 9. What is bad with OpenSource?• You can change anything• Few developers with experience• Harder to evaluate• Frequent updates
  10. 10. Is it possible to go all-inwith open source? • Certainly possible - but is is the right? • It is more of a question how does it support your line of business • It should always be considered! • Should be included in your strategy
