Fix What's Broken. Prove It Worked.
Detection shows you what is slowing delivery down. Correction is how we fix it: safely, incrementally, with a fresh score after every step.
Diagnose. Fix. Verify. Repeat.
The Problem
Most Refactoring makes things worse.
Teams refactor without tests, fix the wrong things first, and can't prove it helped. The codebase ends up worse than before.
Refactoring without tests is flying blind
Teams refactor blind — no safety net, no characterisation tests. Every structural change risks breaking what already works.
Fixing the wrong things first
A developer spends a week on naming conventions while circular dependencies strangle lead times. Without data, teams fix what's visible, not what matters.
No proof it worked
"Tech debt sprint" proposals die in budget meetings because there's no before/after measurement. Just "trust us."
From Diagnosis to Verified Fix
The Workflow
Diagnose & Prioritise
Detection scores your codebase and ranks problems by impact on delivery.
Characterisation Tests
Safety net for existing code — no refactoring without tests.
TDD Refactoring Cycles
Small, tested, committed — one extraction at a time, always green.
Code Review Gate
Architecture boundaries, regression safety, test coverage verified.
Verify & Repeat
Fresh Detection diagnosis confirms the fix worked. Next priority from the list.
What You Get
Safety Over Speed
- Characterisation tests before any structural change
- Every refactoring step is a small TDD cycle, always green
- Code review gate blocks merges that break existing behaviour
Speed comes from confidence, not shortcuts.
Direction Over Intuition
- Detection ranks problems by impact on delivery metrics
- Fix circular dependencies before naming conventions
- Every fix targets the highest-impact problem first
Data decides what to fix. Not gut feel.
Proof Over Promise
- Detection diagnoses before, Correction fixes, Detection re-scores after
- Health scores, debt density, and DORA metrics tracked per sprint
- Board-ready trend lines, not "trust us" arguments
Sprint by sprint. Module by module. With numbers.
What Changes When You Use Correction

Work with us
Debt reduced in small, verified cycles, with the score to prove it.
Correction is how we modernise a platform without stopping the business. Characterisation tests first, small refactoring cycles, and a fresh diagnosis after every fix.
