Los Agilistas sabemos lo potente que es Continuous Delivery (CD) para un equipo Agile. Lo difícil es convencer a dirección del ROI de invertir en CD. Os presentaremos un modelo económico de CD que cuantifica los costes de la integración diferida y deployments manuales, que os ayudará a convencerlos. La charla entera se puede ver en youtube: https://www.youtube.com/watch?v=2-ILyErMUuQ

20. With Continuous Delivery
Engineer costs per unit of time
Machine costs per unit of time
error rate at phase

21. What is the error rate?
error rate at phase
error rate at commit level
time to execute phase
commits per unit of time

22. Without
Engineer costs per unit of time
Time to integrate a new version
Time to release on production
