A Route to Experienced Change and SME Support

Accessing expert external partners can be challenging for smaller organisations or fixed-capacity teams.

With our Fractional Change Partnership solution, you get a flexible, managed service: use only the support you need, when you need it, drawing on your annual investment with CBS.

Fractional Change Partnership

Building societies are evolving rapidly, driven by shifting member expectations, emerging payment technologies, regulatory pressures, and increasing operational complexity. Our Change Partnership brochure sets out how we work with building societies to plan, deliver, and embed change across their end‑to‑end operating model – from member experience and product journeys, through to payments, core platforms, risk, and back‑office processes.

It explains our approach to shaping change portfolios, strengthening governance, and building internal capability, as well as how we help societies manage interdependencies across technology, people, and process. You’ll also find examples of the specific challenges we help address – such as modernising legacy systems, integrating new payment options, improving operational resilience, and supporting cultural and behavioural change.

Download the brochure to understand how we partner with building societies to deliver practical, sustainable transformation that protects members, supports growth, and ensures change truly lands across the organisation.

PMO as a Service

Change portfolios often grow organically over time, leading to fragmented governance, inconsistent delivery, and unclear benefits. Our PMO as a Service offering helps you assess the effectiveness of your current change governance, strengthen portfolio oversight, and build a scalable framework for delivery. Explore the page to see how a dedicated, expert PMO function can bring structure, transparency, and control to your change agenda, while providing a clear roadmap for improving performance and realising value from your investments.

Strategic Alignment and Portfolio Management

Achieving meaningful change depends on making the right choices about where to invest, and then delivering those investments in a controlled, coordinated way. Our Strategic Alignment and Portfolio Management services help you connect your change agenda directly to your organisational strategy, ensuring every initiative has a clear purpose, measurable outcomes, and an agreed path to value.

We work with you to shape and prioritise your portfolio, balance risk and return, and create the governance, insight, and controls needed to manage change at scale. From defining strategic objectives and investment criteria, through to pipeline management, benefits tracking, and portfolio reporting, we provide the structures and support that keep your change activity focused, coherent, and deliverable.
