Business advisory and consulting services
Strategy only matters if it delivers. We collaborate with insurers and asset managers to turn intent into outcomes, bringing together delivery, operations, technology, data and AI with ownership that drives real results.

Turning business strategy into measurable outcomes.
We help insurers and asset managers translate ambition into delivery – improving business performance through target operating model design and business transformation. From product launches to M&A transactions, post-merger integration to operational improvement, we combine deep industry expertise, advanced analytics and hands-on execution to deliver lasting impact at pace.
Our engagements are designed to embed capability within your organisation – strengthening teams, ways of working and outcomes to help reduce the need for on-going external support.
Benefits of working with Milliman
Insurance and asset management expertise
with a fresh perspective
We combine the long-standing established industry expertise with a modern, pragmatic, approach. In a complex environment shaped by regulation, market volatility, technology innovation, and cost pressure, changes are inevitable. Our team will integrate quickly with your team to provide you with an additional layer of capability and experience that allows us to adapt quickly and deliver practical, informed recommendations tailored for you.
Outcome-driven, time-bound engagement
We agree on clear objectives, defined milestones and transparent timelines up front. We avoid open-ended consulting cycles and focus on tangible results, delivered at pace and within your scope, so results land quickly.
Tailored solutions for your business
We don't parachute in with prescribed solutions. We believe every business and every challenge is different. We bring market experience, toolkits, methodologies and example deliverables to accelerate engagement, and we work with your internal experts to tailor them to address your unique challenges.
We build capability, not consultancy dependency
We leave your team stronger than we found it. We improve processes, implement practical solutions and equip your teams with the tools, frameworks and knowledge to sustain progress long after the engagement ends.
Our goal is for you to confidently own the improvement—and keep building on it without us.

Outsourcing and operating model transformation for a major UK life insurer
Led the outsourcing and lift-out of middle- and back-office services, redesigning the future-state operating model and governing the transition to reduce risk, cost and complexity.
Challenge
Our client aimed to outsource middle-office and fund services to a new supplier, with a priority on maintaining operational continuity throughout the transition. The target operating model (TOM) also needed to be redesigned post lift-out.
Approach
We led supplier mobilisation and programme governance, aligning lift-out delivery to the heads of terms. We defined the future-state TOM and transition roadmap and managed the programme end to end from inception through delivery.
Outcome
Lift-out completed within seven months. We reduced operational risk during migration, introduced clearer governance under the new supplier model and lowered the client’s ongoing operating costs.
