Perspectives Covered: Strategy, Business Process, System, Component Specification, Implementation, Operations


Key Variables Impacted: Rule, Data, Function, Event, Network



The Challenge of Updating Prepayment Policies

Prepayment policies in retail lending play a crucial role in balancing customer flexibility with financial stability. Changes to these policies can arise due to regulatory updates, strategic shifts, or market demands. However, implementing prepayment rule changes in real time without disrupting the system is a significant challenge.


Consider a scenario where the finance team decides to introduce a new prepayment penalty structure based on loan tenure and amount. While the change might seem straightforward, it often triggers cascading issues across multiple systems:

  • Inconsistent prepayment penalty calculations across channels

  • Customer-facing interfaces showing outdated prepayment rules

  • Disconnected updates between backend processing and front-end display

  • Compliance reporting reflecting outdated or inaccurate penalty data

  • Increased manual intervention to correct discrepancies


These issues arise because conventional SDLC methods focus on isolated code updates rather than holistic system alignment. The ICMG Enterprise Anatomy Model (Project Edition) offers a structured, multi-perspective approach to ensure seamless prepayment policy updates without causing disruption.


Why Conventional SDLC Approaches Fail

Common Problems:

  1. Hard-coded prepayment rules scattered across multiple systems

  2. UI elements not updated in sync with backend changes

  3. Fragmented data updates leading to inconsistent policy enforcement

  4. Manual overrides to correct discrepancies

  5. Compliance reports reflecting outdated or incorrect data


Root Causes:

The root cause lies in the fragmented approach of traditional SDLC practices, which lack:

  1. Integrated rule management across architectural perspectives

  2. Real-time traceability of data and rules

  3. Coordinated updates to functions, events, and user interfaces

  4. Visibility into how prepayment rules link to business processes


Applying the ICMG Enterprise Anatomy Model (Project Edition)

1. Strategy Perspective

The strategy perspective ensures that the organizational goal of managing prepayment policy changes efficiently is clearly defined and linked to the updated system rules.


Policy Adaptation:The primary strategic objective is to update prepayment penalties while maintaining customer satisfaction and compliance with financial regulations.


2. Business Process Perspective

Identifying the key business processes affected by the updated prepayment policy helps ensure that changes align with strategic goals and operational efficiency.

  • Prepayment Processing

  • Customer Communication

  • Loan Settlement

  • Compliance Reporting

Observation:Clearly identifying impacted business processes helps maintain alignment between strategy and implementation, reducing the risk of inconsistent prepayment rule enforcement.


3. System / Subsystem Perspective (by Variables)
