Background
Saudi Telecom Company (STC), the largest telecommunications provider in Saudi Arabia, embarked on a digital transformation to modernize its monolithic Siebel CRM system. It’s legacy Siebel CRM system managed various functionalities such as service requests, order management, account management, and product management and in their digital transformation, STC adopted several new systems to handle these functionalities.
Our Approach
Our evaluation was divided into two phases to thoroughly assess the application s functionality, design, code quality, and standards compliance.
Phase 1
We explored and tested the application to understand its functionality. We reviewed the Functional Requirements Specification (FRS) documents, identifying gaps and ensuring the proposed solutions met these requirements. We examined both architecture-level and individual-level solutions for comprehensive coverage.
Phase 2
We conducted a detailed code review and analyzed test cases, focusing on resolving identified issues. We assessed the CI/CD processes for compliance with practices and international standards, ensuring the application met functional requirements and maintained high standards of quality, performance, and reliability.
Challenges Faced
Functional Requirements Coverage
For its digital transformation STC needed to ensure that all functionalities of the legacy system were thoroughly captured and replicated in the new system.
Data Accuracy and Migration
Managing the transition from a monolithic architecture to a microservices-based architecture there was a need to ensure that data migration from the old system to the new system was complete and accurate, avoiding any data discrepancies or loss.
Integration Consistency
Whilst this transition there was need to verify that integrations between new systems (PEGA, Kloudville, AEM, EP) and existing infrastructure were seamless and accurate.
Strategy
Comprehensive Documentation Review
Validated that all functional requirements were accurately represented in the new system’s design documents. Identified and addressed any gaps or discrepancies. Reviewed Solution Design Documents (SDD), High-Level Design (HLD), and Low-Level Design (LLD) to ensure alignment with functional requirements and industry best practices. Compared functionalities of the existing Siebel CRM with those proposed in the new system to ensure comprehensive replication.
Code Review & Optimization
Conducted a detailed code review to improve performance, security, and adaptability of the solution. Recommended improvements for efficiency and security and ensured that code was dynamic and adaptable to future changes, avoiding hardcoding and optimizing for flexibility.
Business Outcome
Risk Mitigation
Ensured all critical functionalities of the legacy system were retained in the new system, minimizing disruption with early identification of potential issues and discrepancies, reducing the risk of post-implementation problems.
Technical Assurance
Confidence that the new system is technically sound and capable of meeting all business requirements. Also, addressed potential performance bottlenecks, ensuring the system operates efficiently under load.
Smooth Migration
Implemented comprehensive data migration strategies and support to ensure accurate data transfer and minimal downtime.
