The Challenge 

A UK headquartered bank with over 50,000 employees was in the process of undertaking a major transformation to become fully digital. Their large legacy hardware environment that was central to critical services had become obsolete. The customer had an uncertainty of application and device dependencies across overlapping IT estates, which is not an easy issue to overcome when you consider they had over 100,000 servers in scope to migration, with the added complexity that over 30,000 of these devices were out of support. 

We were tasked to assist in getting the program back on track and into a controlled and assured position as soon as possible to enable acceleration and control moving forwards. 

• Project and team failing against time, cost, and quality of outcome. 
• Not achieving strategic imperatives, which were impacting other initiatives. 
• Inability to touch the platforms that are delivering critical banking services due to uncertainty of application boundaries. 

The Solution 

The team were tasked to focus on creating a subset of the applications that needed to be migrated, to shape an approach that demonstrated success, built trust amongst the business, and set the path for continued migration activities. 

• Re-balanced governance and control. 
• We undertook a visibility and mapping exercise completed over the opening 3 months. 
• Non disruptive execution plan for each part of the critical banking services. 
• Developed exit strategy from their outdated datacenters. 
• Achieved signoff from all stakeholders that they were back in-line with the strategy. 
• Led the execution of the technology activity together with internal staff and vendors. 

The Outcome  

Stable and predictable IT Transformation Program enabling business transformation deliverables: 

• Project successfully completed in 12 months. On time and on budget. 
• No unscheduled downtime and without any need for rollbacks. 
• Established best practice and res
