A practical toolbox for decommissioning legacy systems

As part of a large modernisation programme, BSG supported a leading African bank by creating a practical toolbox to enable effective strategic decommissioning of legacy applications and infrastructure in parallel with cloud implementation plans. 

overview of the clients needs
  • Enable strategic decommissioning of legacy applications and infrastructure across the bank as part of its modernisation programme
  • Prioritise modernisation (and decommissioning) journey based on business criticality, noting all the impacted infrastructure and systems, mitigating risks and reducing associated costs
  • Analyse and understand the bank’s modernisation journey, identify applications and infrastructure to be decommissioned
  • Create a prioritised view of modernisation and decommissioning plans, based on business criticality and dependencies
  • Mitigate risk and minimise the cost of strategic decommissioning across the bank, in line with the modernisation programme 
  • Create a practical decommissioning toolbox that can be applied across all areas of the bank to understand their decommissioning requirements and plan accordingly
  • Visibility across the bank of the prioritised decommissioning programme enabled forward planning, and effective budget and resource allocation
  • A better understanding of financial implications of decommissioning decisions, ensuring the modernisation journey results in maximum benefit while reducing risk
  • A practical decommissioning toolbox that can be used across the bank to understand requirements of the decommissioning process and to support planning processes
  • Upfront planning enabled proactive thinking around decommissioning efforts and dependencies, resulting in a prioritised plan with practical steps for execution
