Trusted by Global Brands. Built for Real Delivery.
Harrison has led some of the UK’s most complex IT transformations — including the world’s largest SIAM implementation. We’re not just consultants; we’re fixers, challengers, and trusted partners to CIOs who want results.

End-to-End IT Delivery — From Strategy to Execution
We operate across the full demand-to-delivery lifecycle, applying frameworks like COBIT, ITIL, DevOps, Agile, SAM, and TOGAF. Whether it’s shaping strategy or driving operational change, we bring structure, speed, and results.

IT Consulting

We’ve Lived Your Challenges. Now We Fix Them.

Every organisation has its quirks — but the problems? They’re often the same: broken processes, misaligned models, and frameworks applied without context.

At Harrison, we don’t do cookie-cutter consulting. We tailor every engagement to your outcomes, not someone else’s playbook.

We blend the best of ITIL, COBIT, SIAM, Prince2, Agile and more — not to tick boxes, but to build solutions that actually work across your enterprise. No fluff. Just results.

IT Service Delivery & Management

Service Capability — Delivered, Not Just Staffed
We provide full-spectrum service delivery capability — from running change management and ITIL practices to leading service improvement plans and coaching your internal teams. Whether you need interim leadership, hands-on delivery, or transformation support, we bring the tools, the talent, and the outcomes.

IT Management Consultancy

Strategic IT Consulting for Complex Change
Major change demands more than advice — it needs leadership, structure, and delivery. Harrison provides expert-led consulting across IT strategy, operating models, governance, and transformation. We bring the right capabilities at the right time to drive real outcomes, not just recommendations.

Software Asset Management

SAM That Starts With Reality — Then Drives Results
We baseline your current SAM maturity to expose gaps, risks, and opportunities. From there, we build tailored improvement plans that align with your business goals — not just compliance checklists. Real insight. Real control. Real value.

SIAM Assurance Service

SIAM Strategy, Delivery, and Recovery — Built for Reality
Whether you’re exploring SIAM for the first time, recovering from a failed implementation, or considering a rewind, we help you make sense of it all. We work with retained organisations to design fit-for-purpose SIAM models, provide impartial assurance, and even execute assurance on your behalf. From strategy to governance to hands-on delivery — we make SIAM work in practice, not just in PowerPoint.

People

Build Capability Through People — Not Just Processes
Your people are your biggest lever for change. We help develop ITSM capability through coaching, mentoring, and hands-on support — from service managers to practice leads. Whether it’s uplifting skills, embedding new ways of working, or driving cultural change, we make sure your people are equipped to deliver and evolve.

Harrison

We Don’t Chase Level 5. We Chase What Works.
Not every organisation needs NASA-level maturity. We help you define what “good” looks like for your business — and build the capability to get there. Whether that’s Level 2, Level 4, or something in between, we align your IT services to your strategy, not someone else’s framework.

We Know What Good Looks Like — And How to Get You There.

Reliable, stable, and predictable IT services don’t happen by accident. We help you build well-governed, high-performing IT capabilities that actually deliver — not just look good in a maturity model.

From Advisory to Execution — We Deliver the Full Lifecycle.

Whether you need strategic consulting, transformation support, or someone to run the capability for you — we’ve got it covered. We deliver full lifecycle IT capability, aligned to your cost, quality, and strategic constraints.

Our Goal? Make You Brilliant at IT.

Everything we do is about helping you deliver better IT services to your users and customers — services that support your strategy, enable your teams, and drive real business value.

We care about outcomes.

We’ve collaborated with thousands of enterprises, providing them with IT consulting support. With an impressive 99% customer satisfaction score and a strong 97% customer retention rate.
