Turning around failing digital delivery and service

Digital Delivery • IT Service Management • Operating Model Design

I help organisations stabilise delivery, reshape services, and design operating models that actually work in complex, regulated environments.

Most of my work starts when something doesn’t feel right — delivery is slipping, services aren’t landing, or the model isn’t holding.

Delivery turnaround: Led a five-person SWAT team across the UK and Netherlands to define a back-to-green plan, securing stakeholder approval in two weeks and targeting ~30% cost reduction. Service transformation: Led a cross-functional team to build a four-year transformation roadmap delivering ~£4m OpEx savings with zero CapEx spend across a multi-supplier application estate. Operating model design: Shaped a Shared Application Services operating model securing cross-supplier and ExCo buy-in, underpinning a 10-year shift from 10% to 80% SAS-managed applications.

The problem

Most organisations do not need another disconnected model

Most delivery problems are not technical. They are structural.

They need digital delivery, IT service management, and connected governance to work together in practice. That is where my background across programme and managed service delivery, organisational change, transition, and operational leadership becomes useful.

I have spent 20+ years working within in-house teams, global outsourcers, systems integrators, and SMEs, helping clients bridge the gap between heritage and modern, digital delivery approaches, ensuring this new reality meets commercial and stakeholder expectations.

  • Delivery off track or losing control
  • Support and maintenance disconnected from product delivery
  • Supplier and team interfaces creating friction and delay
  • Leadership lacking visibility, grip, or confidence
  • Operating models no longer aligned to business need

I am typically brought in when:

  • Delivery is slipping and confidence is dropping
  • Service performance is unstable or under scrutiny
  • Run and Change are disconnected
  • Leadership needs clarity on what is really happening
What I do

Three ways I typically help

I work with organisations to stabilise delivery, strengthen live service, and redesign operating models where control, confidence, and performance are at risk.

01Delivery Turnaround

Stabilising complex programmes where delivery has drifted, re-establishing control across cost, schedule, and outcomes to protect investment and restore confidence.

Governance reset, stakeholder alignment, and delivery visibility, combined with pragmatic recovery planning and commercially viable execution that brings programmes back onto a credible trajectory.

I am typically brought in when:

  • Delivery is slipping and confidence is dropping
  • Leadership needs clarity on what is really happening
  • Programmes need a credible path back to control

02Service Transformation

Transforming live service environments to improve performance, resilience, and user experience, while reducing operational risk and total cost of ownership.

Integrating Run and Change through ITIL-aligned service improvement, transition, and performance management, ensuring services are scalable, measurable, and aligned to business outcomes.

I am typically brought in when:

  • Service performance is unstable or under scrutiny
  • Transition into live is high-risk or under pressure
  • Run and Change are disconnected
View proof

03Operating Model Design

Aligning Agile, ITIL, and DevOps into a practical operating model that enables consistent delivery, service performance, and governance across complex organisations.

Organisation design, role clarity, governance, automation, and integrated delivery-and-service ways of working that improve efficiency, reduce friction, and support sustainable, outcome-driven execution.

I am typically brought in when:

  • Operating models no longer support delivery in practice
  • Teams, suppliers, and governance are working at cross-purposes
  • Leadership needs a model that will hold under pressure

Case studies

Selected case studies

Examples showing how I work across turnaround, transformation, operating model design, and service transition in complex, regulated environments.

Delivery Turnaround

Siemens TOPAS NWE Transformation

Problem: Siemens’ SAP Application Management model in North West Europe had drifted away from its approved operating model, missing cost and quality targets.

Action: Led a five-person “SWAT team” to define a back-to-green transformation plan centred on near-shore delivery, lean ITIL processes, and standard tooling.

Outcome: Secured approval within two weeks, with a model targeted to achieve ~30% cost reduction.

Service Transformation

BBC Project Stratus

Problem: The BBC needed to improve ROI across a complex, multi-supplier application estate while reducing duplication, standardising platforms, and mitigating obsolescence risk.

Action: Led a multi-disciplinary team to build a four-year roadmap using a transformational scorecard for high-risk, low-fit applications and a funding model tied to operational savings.

Outcome: Delivered with no capital expenditure, generating ~£4m in operational cost savings while enabling rationalisation and modernisation.

Operating Model Design

Home Office Shared Application Services

Problem: The Home Office needed a future operating model for Shared Application Services across a supplier landscape split between digital and legacy ITO approaches.

Action: Acted as a trusted advisor within the supplier “Rainbow Team”, shaping the Future Mode of Operation around squad-based delivery, blended practices, and integrated toolchains.

Outcome: Secured buy-in across project leadership, suppliers, and DDaT ExCo, enabling detailed design and transition and underpinning a 10-year transformation programme that increased SAS-managed applications from 10% to 80%.

Service Transition

Atlas Integration & Enablers Transition

Problem: A high-risk supplier transition (BJSS → Mastek) across a critical integration layer threatened knowledge loss, delivery disruption, and downstream impact on dependent services.

Action: Coached, assured, and governed the transition, introducing checkpoints, readiness criteria, and a Microsoft 365-based Service Transition Accelerator.

Outcome: Delivered with no material disruption, protecting a £21M capability while improving risk visibility, onboarding speed, and delivery confidence.

Framework

A structured approach that actually works

This is how I make delivery and service work together.

I have my own bespoke delivery and operations framework, ABBOT, a practical, end-to-end framework that unifies Disciplined Agile Delivery (DAD), DevOps, and ITIL into a single, coherent lifecycle.

It is designed to balance the governance language and structures trusted by executives with the flexibility, adaptability, and speed required by delivery teams. In practice, that means connecting inception, construction, transition, and live operation through one operating rhythm rather than treating delivery and service as separate worlds.

ABBOT is how I translate strategy into delivery structure, integrate Run and Change, and create a model that works both for leadership oversight and for teams who need to deliver outcomes at pace.

  • Executive-ready governance and decision structures
  • Integrated delivery, transition, and live-service thinking
  • Practical alignment between business, development, and operations

In practice, this means I can step into a live situation quickly, understand what is really happening, and start making it better without slowing things down.

About

Hello, I’m Lleyam

I’m a Digital Delivery and Service Management professional with 20+ years’ experience leading delivery, service operations, transition, and transformation across complex, regulated environments.

My career has first been built on digital delivery and managed services across complex application and service environments. It also spans organisational change, transition, and operational leadership, giving me the grounding to help clients move from instability to control. Around that core, I have shaped value propositions and supported deal architecture, which means I understand not only how services run, but how they are positioned, governed, and funded.

I have worked in-house, with large outsourcers, systems integrators, and SMEs, and I’m most useful where strategic thinking, commercial awareness, and hands-on execution all need to come together.

I’m typically brought in when services need to perform better, delivery needs to regain control, or a client needs a credible advisor who can think strategically, shape the narrative, and execute practically.
