7th NA Huddle – From 72 Hours to 3.5: A Quality-Driven Redesign

7th North America Huddle – From 72 Hours to 3.5: A Quality-Driven Redesign of Retroactive Billing

What if the real reason a system is slow isn't the amount of work it does, but the way that work is designed?

This session tells the story of a retroactive billing process in a healthcare platform that took approximately 72 hours to run at full production volume. The deeper problem was that its core calculation was tightly coupled with invoice generation, making the process difficult to test, validate, and optimize.

The breakthrough came from treating it as a testability problem first — separating the retroactive calculation into an independent stage before invoice generation. The result: processing time dropped from 72 hours to roughly 3.5 hours, while maintaining rigorous quality and financial validation.

Session – From 72 Hours to 3.5: A Quality-Driven Redesign of Retroactive Billing

Speaker: Vinitha Kalappurakkal

The session explores how architectural decisions can make a system both easier to test and dramatically faster.

You’ll explore:

• Why an untestable system can be the real root cause of slow validation.
• How decoupling retroactive calculations from invoice generation enabled independent verification.
• How a ten-gate quality framework can align validation with architecture — from data readiness and logic accuracy to reconciliation and regression.
• Why performance and quality don't have to compete: the redesign delivered a 95% reduction in processing time while maintaining existing validation standards.
• How the same thinking can apply to other slow, tightly coupled “black box” processes.

How This Huddle Solves Your Problem

• Testing a complex process takes too long? Look at whether the architecture itself is making validation difficult.
• Your system behaves like a black box? Explore how decoupling can create independently testable components.
• Quality gates feel disconnected from the system? Learn how validation can map directly to architectural stages.
• Performance improvements risk reducing test coverage? See how designing for testability can improve both speed and confidence.

Why Show Up on 4 November?

• Because slow testing may be an architecture problem, not simply a volume problem.
• Because decoupling isn't just an engineering strategy — it can be a powerful QA strategy.
• Because you'll see how a 72-hour process was brought down to roughly 3.5 hours without sacrificing validation rigor.
• Because the real lesson goes beyond billing: designing for testability can unlock performance.
• Because sometimes the fastest way to improve a system is to first make it easier to test.
