Waterfall & Frankenstein

Page 3: Waterfall-ITIL vs Agile-DevOps

Waterfall has many high-risk & hard-to explain complexities under the covers

Page 4: Waterfall-ITIL vs Agile-DevOps

Historically, it has proven to be slow, unreliable & disappointing

Page 5: Waterfall-ITIL vs Agile-DevOps

It’s s Alive!And it appears almost miraculous if you can make it work

Page 6: Waterfall-ITIL vs Agile-DevOps

Yes, it is working! But is it repeatable or sustainable?

Page 7: Waterfall-ITIL vs Agile-DevOps

- How big is your pizza? How many teams needed?- Code as Asset…Code Reuse as a standard….

- Fewer moving parts, more code IP to protect

- Faster moving process, to grow the business

ITIL and Asset Management…always expected Waterfall Apps!- Millions of Code lines- Thousands of contributors- Hundreds of features- Over many years- Big and disruptive!

DevOps and Asset Management…always expecting Agile Apps!- 10’s of Code lines

- 5-7 Micro teams

- 3-7 Features

- Over 3-6 weeks

- Small and invisible!
