Largescale acquisitions often focus on balance sheets, market access, and brand portfolios. What receives less attention, until it goes wrong, is the technology that must quietly detach from one organisation and integrate into another without interrupting customers or staff. We have just come to the end of a multiyear IT programme with an Indian business that demonstrated how a disciplined execution can turn a regulatory deadline into a long term platform advantage.
Our programme began after a majority acquisition required an insurance business to exit a longstanding shared service with a former India High Street banking parent. Core technology functions, from identity and email to Data Centres and networks, were deeply intertwined. At the same time, the organisation could not afford disruption to its claims processing, underwriting, or 30 branch operations. The timetable was fixed (by the Indian Finance Regulator), the complexity high, and tolerance for failure low.
This was not going to work as a single cut-over, we approached it as a structured transformation with a clear narrative. The early months were focused on discovery and truth finding. It does amaze me the times we have undertaken these Programmes the environmental picture before we get on site and the one after we have been on site are vastly different. The Project Technical teams mapped applications, infrastructure, identities, and data flows to understand what was genuinely shared and what could be separated. This avoided a common pitfall in mergers and acquisitions, where assumptions hide dependencies that surface too late.
With that foundation in place, a future state design was developed for each discipline that balanced independence with readiness for later integration works. The target was not just to leave the shared services with the Bank, but to establish an enterprise ready environment that could meet the new parent’s global standards. This shaped every decision that followed, from directory architecture and security tooling to workplace standards and service management.
Execution then moved into a tightly sequenced separation phase aligned to the very tight regulatory window of just 6 months. A new office and branch connectivity was onboarded, local Wi-Fi implemented and subsequent issues resolved, and a new Active Directory stood up alongside new user accounts for 2,000 staff. A factory style workplace programme was set up and the end user devices were stripped of its data and rebuilt from the factory default state and standardised thousands of endpoints. We then moved user data (email and personal business data) into Microsoft 365, and gave staff a consistent experience at pace.
In parallel, the infrastructure backbone was rebuilt (new network and security appliances). A new production Data Centre was sourced, designed, built, and systems migrated with rehearsed cutovers and operational readiness checks. Later, a dedicated Disaster Recovery Data Centre site was added, complete with documentation and a proven recovery test. These moves did more than satisfy immediate requirements, they raised the organisation’s resilience and operational maturity.
Security was treated as an enabler rather than a hurdle. Endpoint and server protection, encryption, logging, monitoring, and web application controls were deployed as a coordinated uplift. Vulnerability reduction was measured using regional tools and driven to target levels, enabling approval for direct connectivity of the India environment into the new parent global network. This sequencing mattered. Connectivity was earned through evidence, not assumption.
One of the quieter successes of the programme was service continuity. Throughout sustained change, the service desk absorbed waves of migrations, rebuilds, and user transitions. Clear communications, training, and issue triage kept productivity stable while the foundations were rebuilt underneath the business.
By project close, the organisation was operating on a standard IT estate, no longer dependent on shared banking systems. Identity, workplace, network, and Data Centre services were under local control, with support from the parents regional support teams, with a clean platform for that enabled integration and connectivity with the global parent. Service management was modernised, legacy recovery services were decommissioned, and remaining dependency led work was handed cleanly to business as usual teams.
The wider lesson is not just a technical success. The one thing we have learnt over the many years of delivering successful separation programmes is that they hinge on governance, sequencing, and transparency. Decisions must be visible, dependencies clearly understood, and progress measured against outcomes rather than activity. When those disciplines are in place, regulatory deadlines become forcing functions for improvement rather than sources of risk.
In a market where mergers and acquisitions continue to accelerate, this programme offers a timely reminder that separations (along with Integrations) done well is not merely about untangling the past. It is about building a future ready platform that allows the business to move forward with confidence, resilience, and control.
Summing up at the Project Closure the Project Sponsor (Regional Chief Technology Officer) said, ‘To reflect back on this Programme, it’s really taught us all new skills. It’s a fantastic opportunity to be part of something like this and again, I know we’ve said it before, but to everybody that contributed.
This really shows the level and the width and breadth of the team that participated in both the ‘parent’ side of the fence and in India. Well done, and to the Bushey IT Change team as always.
Steady, professional, calm, outcomes based, yet another success. I thank you for everything that you’ve done. It was a wonderful example of how a project like this should be managed and you’ve done yourselves proud.
So, thank you very much for all of your efforts as well from my side.’
This Bushey IT Change thought leadership piece explores a regulatory‑driven IT separation showed that disciplined sequencing, strong governance, and early security uplift can deliver independence without disrupting the business.
The programme proved that trust, transparency, and operational focus can turn a complex carve‑out into a resilient, future‑ready technology foundation.
