Dynamic Deposit Rate Engine for Legacy Banking Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy banking systems are inflexible and difficult to update, making it cumbersome for financial institutions to implement promotional offers like upgraded interest rates to select clients, and inconvenient for clients to activate these offers across online and branch office systems.
Innovation Solution
A deposit rate promotion system architecture that serves as a hub between existing bank systems, enabling real-time and batch data transfer, allowing authorized managers to define criteria for eligible clients to automatically receive promotional rates upon qualifying actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a promotional offer system is built using legacy banking systems, then the system can securely manage critical data, but the system becomes inflexible and difficult to update to accommodate new business practices
Solution Approach 1:
The system is divided into two distinct layers: a legacy banking system layer that securely manages critical data (maintaining reliability) and a promotional offer management layer that handles new business practices and promotional campaigns (providing flexibility). This segmentation allows each layer to independently fulfill its specific function without compromising the other.
Solution Approach 2:
A new promotional offer management system acts as an intermediary layer between the legacy banking systems and the promotional offer delivery mechanism. This intermediary layer communicates with the legacy systems through defined interfaces, enabling flexible promotional campaign management while preserving the stability and security of the underlying legacy infrastructure.
2Device complexity
If clients must use promotional codes to redeem offers, then the legacy system architecture is maintained, but the client activation process becomes inconvenient and complex
Solution Approach 1:
The promotional offer system automatically identifies eligible clients based on predefined criteria and delivers offers directly to them through their existing banking channels. Clients simply need to perform qualifying actions (such as opening an account or making a deposit) to automatically receive the promotional benefit, eliminating the need for manual code redemption and significantly improving ease of operation.
Solution Approach 2:
The system pre-configures promotional offers with eligibility criteria and automatically matches them to qualifying clients before the clients need to redeem them. This preliminary setup and automatic matching eliminates the need for clients to manually enter or redeem promotional codes, making the activation process seamless and convenient.
3Ease of manufacture
If promotional offers are implemented through manual code redemption, then implementation is simpler for legacy systems, but productivity and efficiency of promotional campaign deployment are reduced
Solution Approach 1:
The promotional offer management system uses configurable parameters and criteria that can be easily modified through a user-friendly interface. Bank managers can define eligibility criteria, offer terms, and target client segments by setting parameters rather than coding, which maintains implementation simplicity while dramatically improving campaign deployment efficiency and productivity.

AI summary
A system architecture for offering an upgraded deposit interest rate to certain clients using a method which is easy for the financial institution to implement and convenient for the clients to accept. A deposit rate promotion system is built in a configurable programming environment. The deposit rate promotion system serves as a hub between other existing bank systems—including back-end systems which control client and account information, and client-facing systems in the form of digital banking systems and employee-operated branch office systems. A bank employee implements a new deposit rate promotional campaign in the system by defining criteria for eligible clients and other parameters. Eligible clients need only perform the qualifying action, such as opening a new account of the prescribed type, in order to receive the promotional deposit rate. The system architecture includes adapters and interfaces required for both real-time and batch data transfer between all affected bank systems.
