Case studies


Large scale credit card migration, embedding within various Issuer teams

  • Built out the entire TS2 options environment
    • Through iterative analysis, ensured the system configuration was accurate and resulting in no core processing issues from the delivered configuration
    • Provided guidance and best-practice to help inform Issuer configuration selection
  • Led data verification and first occurrence
    • Automation of verification for TSYS <–> TSYS mapping
    • Led further manual verification of TSYS <–> TSYS mapping
    • Verification for Client internal platforms
  • Created data mapping specs for client Operational Data Store (ODS)
  • Supported incident management with triage, analysis and fix design, as well as any remediation efforts to correct customer or business impact
  • Solving for feature or process gaps in readiness for migration
  • Support of UAT

Doxa retained on a servicing agreement following migration, to give additional warranty due to specialist expertise.


Doxa has worked with multiple clients, leading them through build, test and deployment that enables the Issuers to run promotional campaigns at both Acquisition time and for backbook existing customers

  • Doxa developed and utilised a solid play-book, which has helped multiple clients to launch promotional credit card products and campaigns to the market
  • Our questionnaires and requirements gathering processes uncover key decision points and help clients to consider the unknowns
  • Creation of the full end to end solution, including both the implementation of the processing configuration items to meet business requirements, and for any identified development needs
  • Test scripting, management and delivery
  • Implementation, and first occurrence verification
  • Flawless execution to put the products / campaigns live in market

On behalf of a leading global cards processor, work was undertaken with one of their key strategic central-European Issuers to prepare both sides for an up-coming large cards portfolio migration and, specifically, assessing readiness for the initial ‘Discovery’ phase of the project

  • The engagement looked to qualify the status of migration requirements across the entire Cards Value Chain, leveraging Doxa’s tools and run-books.
  • Creation of a suite of documents for system configuration and development requirements for the target processor. Artefacts included:
    • Pre-Discovery Integration Diagrams
    • Inputs to Servicing Matrix
    • Discovery Modular Session Inputs
    • Requirements Traceability Matrix
    • Pre-Emptive Development Item List
    • Project Scope Document
    • Decision & Actions Log
  • Enabled processor and Issuer to carry out a focussed & streamlined Discovery phase, illuminating all subjects that required additional preparation to ensure a successful outcome.

Supporting an issuer with their digital transformation programme, replacing the use of legacy solution components with new technology

  • Identification of integration end-points required to underpin the chosen feature sets
  • Detailed mapping of the chosen features data-usage, and available API functionality to support those features
  • Cost analysis of various solution components, with recommendations from both cost and feature perspectives
  • Identify differences and/or gaps between legacy & new technology solutions, including analysis of current and target solution architecture
  • Creation of API collections for use by the client and various conditioning completed in order to produce sample data to aid solution context
  • Construction of feature specific test scripts, with emphasis on known problem areas gained from vast previous experience
  • Support of integration testing, issue analysis and solution recommendations
  • Assist the implementation through each stage of Software Development Life Cycle (SDLC)
