A three-hundred-year-old fintech that has to open on time, every time
London Stock Exchange Group is one of the world's most systemically important financial market infrastructure providers. As its CEO, Dame Julia Hoggett, puts it, LSEG is "a three hundred year old fintech" - it opens on time, closes on time, and gets everything done in between.
That standard applies to every release and disaster recovery event that keeps the exchange running. Before Cutover, coordination was largely manual and fragmented, with plans spread across different tools - making it hard to build a complete, confident picture of an event early enough to plan around it.
The challenge
LSEG's technology and resilience teams needed total confidence in complex releases and DR events - not just that they'd succeed, but visibility into where things stood at every point. With plans scattered across tools, teams had limited early insight into how activities and dependencies connected, so risk showed up later than anyone wanted.
The solution
Cutover replaced the patchwork with one shared runbook.
Early dependency mapping gives teams insight into how activities connect before the day of the event, so the plan can be stress-tested in advance.
One coherent, shared plan means every stakeholder works from the same runbook - no one asking whether a task is done.
End-to-end observability runs through planning and execution alike. Leadership, including LSEG's CEO, can see each step of a complex, cross-team event as it happens.
The outcome
The result isn't that LSEG moves faster on the day - it's that the work has been planned, rehearsed, and controlled well in advance. That discipline makes delivery predictable at pace.
As Cutover CEO Ky Nichol notes, organizations often discover their true capacity for running critical events during the event itself. LSEG and Cutover are building the discipline to find that out in planning and simulation instead - well before it counts.
For LSEG, the goal isn't to talk about resilience. It's to quietly get on with it, so customers only ever see good change, delivered well.
Key Results
- Fragmented tools consolidated into a single shared runbook
- Dependency mapping shifts risk discovery into the planning phase
- End-to-end observability across planning and execution
- A repeatable discipline of planning, rehearsal, and simulation built in partnership with Cutover
We have far much more observability, not just during the planning phase but during execution. Detailed dependency mapping give us early insight into how activities connect and where the dependencies lie. This means we can share the approach much earlier and as a result risk is result, delivery is controlled. - Mark Sturtevant, Markets Release Management & DR, LSEG
