Agile Singapore 2014 Conference

The main message is continuous delivery of real value while dealing with complex technical challenges. In other words, don't say 'no’ to business because systems are old or a "big ball of mud". A problem many large enterprise organisations have today begins with a promise of business value over few year. But first thing an IT department “needs" to do is implementation of some technical fundament or legacy replacement, while business is waiting.

This is a story about gradual replacement (StranglerApplication) of large, business-critical, 24/7 systems with very high quality requirements, used Agile practices in dealing with architecture, migration, and enterprise aspects. It is about new way in dealing with complex architectural questions (compared to traditional architecture processes) where everyone is involved, emergent design, and simplicity.

It is also a real-life story about 4 cross-functional Scrum / DevOps / feature teams working together and with many stakeholders for 4 years, delivering value with new version in production, every 2 weeks. The talk is an example of false dichotomies that agile and architecture need to compromise, or "without QA people you will have a big mess in such projects".
The story can also be read in this paper. It is currently being edited for posting on InfoQ.
