Implementation of Smoke Testing as Part of a Strategyquality Assurancein the Framework of Migration of Technology System Changetreasury Wealth Management at PT Bank Danamon Indonesia

Abstract

PT Bank Danamon Indonesia is one of the largest national banks in Indonesia with an extensive network of 846 conventional branches and Sharia units. Supported by more than 60,000 ATMs (including the ATM Bersama, PRIMA, and ALTO networks), Danamon serves customers in 34 provinces. As of September 2025, Bank Danamon managed consolidated assets of Rp. 259.5 trillion and its strategic focus in 2026 includes growing Assets Under Management (AUM) in wealth management by 20%. With such large business development, Bank Danamon is migrating its technology system in one of its business products, Treasury Wealth Management. Migrating the old technology system to a newer one is necessary to more quickly process transaction data needs on a larger scale. Challenges arise where the old or previous technology system differs from the updated one both in terms of the technology brand and the principal implementer of the system. This difference is quite crucial in changing a technology system, because it involves everything from data structure, programming, to maintenance. Meanwhile, the system's features and behavior are already well-established across Bank Danamon's branch and customer network. Furthermore, the data and transaction reports from the legacy system are already meeting existing needs. Therefore, the migration to the new system needs to be carried out partially to avoid disrupting services running on Bank Danamon's treasury and wealth management products. Implementing smoke testing as part of a Quality Assurance strategy is the best scenario to support this partial migration process. Smoke testing can prioritize feature releases to the production environment without disrupting the existing system.
