Strangling the monolith – with Amjad Sidqi

This is a real-life story of how one team successfully rewrote a legacy health insurance system with thousands of unknown business rules so complex that no one could make heads or tails of them – and a tiny mistake could put millions of dollars at risk.

Through an analysis of the scenario, Amjad Sidqi and David Julia will share how you can:

• Build statistically significant confidence in your system with data-driven testing
• Take a Lean approach to legacy rewrites to strangle the monolith safely
• Validate your system’s accuracy when you don’t know the legacy business rules
• Get business and QA buy-in to leverage continuous delivery in a legacy environment
• Demonstrate progress on your legacy rewrite so that your project doesn’t get cancelled.
