Executive Risk
Core modernization risk is not only technical. It is operational, financial, and reputational.
For CTOs, CIOs, and CBS programme directors, core modernization risk is operational, financial, and reputational as much as technical. The bank must keep products, balances, accounting, channels, payments, controls, reporting, and customer journeys reliable from day one while avoiding go-live defects, delays, budget pressure, reconciliation gaps, integration instability, and weak readiness evidence. Yethi helps leadership expose these risks earlier, validate what matters across migration, upgrade, replacement, and BAU change, and make go/no-go decisions with clear proof instead of disconnected status reports.
Modernization Coverage
Assurance across the modernization scenarios banks actually face.
Yethi structures core banking testing around the decision points that matter to technology leadership: risk, readiness, speed, auditability, and business continuity.
Core Transformation
End-to-end business journey validation across new CBS implementation, migration, legacy coexistence, integrations, channels, and downstream systems.
BAU and Regulatory Change
Product launches, compliance changes, workflow updates, fixes, enhancements, and repeatable regression cycles after go-live.
Methodology
A governance-led path from transformation risk to go-live confidence.
Yethi combines banking domain knowledge, proven CBS testing methods, reusable test assets, automation, and release governance so modernization teams can move faster without losing control.
