Når et software-produkt løbende bliver forbedret, så vil vi jo gerne give brugerne forbedringerne i hænderne så hurtigt og let som muligt. Continuous Delivery er automatiske test og automatiseret deployment strikket sammen, så I bare skal lave lækre features og checke ind - så klarer automatikken resten. Vi ser på hvordan man sætter den nødvendige infrastruktur og automatik op, så de gode tilføjelser og rettelser til koden hurtigt og automatisk flyder ud til slutbrugerne - og de knap så gode bliver stoppet undervejs.

is the answer to 2 questions:
• When we improve the code, when should the uses get it?
• What if our change is not an improvement?
and how easily we can achieve that.

• New to me - I’m wondering what it is?
• I know the theory, but would like to learn about practicalities
• Half way - tell me more
• Come a long way, but I’ve hit a snag
• All the way - I’d like to share
• It ain’t gonna work
