How to build a business case for changing your MSP provider

BLOGBy Rullion on 30 September 2025

Switching Managed Service Programme (MSP) providers is a major decision. Your first-generation MSP often brings early wins: reducing admin, consolidating suppliers, and bringing much-needed structure to hiring. But as your organisation evolves, those solutions can fall short. Visibility isn’t where it needs to be, processes don’t adapt, and the programme stops keeping pace with future goals. Often, these challenges can be addressed through open conversations with your current provider. But when they can’t, it may be time to consider changing your MSP provider and moving to a second-generation MSP provider, your next partner.

5 signs it’s time to switch MSP providers

For leadership, the decision often comes down to proving the return on investment, reducing risk exposure, and ensuring the MSP evolves alongside strategic priorities. Knowing when to make that move isn’t always straightforward, but there are common warning signs that can strengthen your business case:

Limited visibility

If you can’t access accurate, real-time data on workforce spend, supplier performance, or compliance, you’re operating blind. This makes it harder to control costs, demonstrate ROI, or make strategic decisions.

Processes that don’t adapt

When workflows remain rigid and fail to keep pace with evolving business needs or regulatory changes, inefficiency creeps in. This often leads to bottlenecks, slower mobilisation, and higher risk exposure.

Misalignment with strategy

Your MSP provider should act as a partner, not just an administrator. If the programme feels transactional and disconnected from your long-term workforce goals, it weakens your ability to deliver against wider business priorities.

Supplier limitations

An MSP that relies on a narrow supplier network restricts access to talent. This not only slows down hiring for specialist roles but also prevents you from tapping into under-represented or overlooked talent pools.

Lack of innovation

If reporting hasn’t improved in years, technology feels outdated, or the provider isn’t pushing continuous improvement, your MSP may be holding you back instead of helping you move forward.

The next step is turning these challenges into a structured argument that leadership can’t ignore: your business case.

What to include in a business case for switching MSP providers

The issues you’ve identified become the evidence, and the improvements you’re aiming for become measurable objectives. By structuring your case around these points, you’ll give stakeholders the confidence that switching MSP providers is a strategic decision, not just a reaction to frustrations.

Executive summary

Think of this section as the “elevator pitch” for your case. If a senior leader only reads one page, it should answer: Why change now, and what will we gain?

Example: Our current MSP model is not providing the visibility, flexibility, or supplier reach we require. By transitioning to a second-generation provider, we can reduce average cost per hire by 15%, cut mobilisation timelines by 20%, and ensure full compliance visibility across our workforce.

Current challenges

This is where you turn warning signs into hard evidence. Leadership will expect more than anecdotes, so use data to back up your points. The stronger your evidence, the harder it is to ignore. Think rising time-to-hire figures, compliance gaps, or supplier underperformance.

Example:

Reporting dashboards are limited, preventing us from tracking supplier performance in real time.
Average time-to-hire has risen from 28 to 53 days over the past 12 months, delaying project starts.

Objectives

Objectives show what success looks like after the switch. They should be specific, measurable, and tied directly to organisational priorities. Think of this as the “destination” your business case is leading towards.

Example:

Reduce time-to-hire for technical roles by 20%.
Achieve 100% compliance audit readiness.
Introduce real-time workforce reporting by Q2.

Options analysis

Show leadership that you’ve weighed alternatives fairly.

A strong business case doesn’t assume switching is the only option. It shows leadership that every alternative has been considered. Presenting a fair comparison between staying with your current provider and moving to a new one makes your recommendation more credible and balanced.

Example:

Option 1: stay with current provider

Pros: continuity.

Cons: persistent issues unresolved.

Option 2: switch to new provider

Pros: wider supplier network, improved tech, better compliance.
Cons: transition costs, short-term disruption (if not managed effectively).

Cost-benefit analysis

Demonstrate how switching creates measurable financial and strategic gains. This could be savings on cost per hire, avoided compliance penalties, or improved project delivery that translates directly into revenue.

Example:

Based on current hiring volumes, a reduction of £1,500 per hire equates to £225,000 in annual savings.
Avoided compliance fines (based on previous breaches) estimated at £50,000 annually.

Implementation plan

Even the best business case will raise the question, “How will we manage the transition?” Your implementation plan reassures stakeholders by showing how risks will be controlled and disruption minimised. Break the plan into phases and set realistic timeframes.

Example:

Phase 1: shadow mode (Months 1–2).
Phase 2: 50% requisitions managed by new MSP (Months 2-3).
Phase 3: full handover (Months 4–6).

KPIs and success measures

Defining KPIs upfront makes your business case measurable and accountable. This section shows how success will be tracked after implementation. Clear measures help leadership see the long-term value of change.

Example:

Reduce average time-to-hire from 48 to 38 days within 6 months.
Achieve 95% supplier compliance with the agreed SLA by Q3.
Deliver full visibility of workforce spend by year-end.

Demonstrating ROI: cost vs value

Boards rarely approve a switch without seeing hard numbers. To win them over, your business case must prove that the value of change outweighs the cost of disruption. A simple three-step ROI model makes this clear: the cost of staying put, the cost of switching, and the value gained. Each step should be backed up with data and, where possible, linked to strategic business goals.

1. Cost of staying put

(Average cost per hire × annual hires)
Compliance breaches, project delays, supplier mark-ups

2. Cost of switching MSP providers

Transition fees, internal resource time, short-term disruption

3. Value gained

Savings from lower mark-ups
Reduced compliance risk
Faster mobilisation and delivery
Stronger supplier performance

Example:

Our NWG MSP partnership: In 2025, NWG required mobilisation of Information Services (IS), data, cybersecurity, and change management roles with a 4-week deadline (over Christmas) to support their digital transformation.

100% of contractors were transitioned on time, despite a condensed four-week window and minimal legacy data.
Effective contingent workforce management with zero disruption to services, preserving business continuity across mission-critical information systems projects during a peak period for infrastructure planning.
£15,000+ saved in the first month alone through improved fulfilment routes and transparent rate control.

This example illustrates how value can be realised quickly. And, when combined with the ROI framework above, it helps build a case that is both credible and compelling.

Managing risks during the transition

Even with a strong business case, leaders will ask, “What’s the risk?” Anticipating these concerns will make your case more persuasive. For more guidance, our MSP Implementation Question Checklist highlights the questions you should ask during mobilisation to ensure your programme is set up for success.

Operational disruption – delays in hiring or mobilisation. The mitigation for this would be a phased transition, a parallel run for 1–2 months before full handover.
Supplier resistance – Preferred suppliers may hesitate to engage. Early communication, clear SLAs, onboarding support
Knowledge transfer gaps - Knowledge transfer gaps. Structured handover between outgoing and incoming MSP
Compliance lapses – Risk of exposure during transition. Align compliance checks with new provider from Day 1

Securing stakeholder buy-in

Different stakeholders view value differently. Map their concerns to your business case:

Finance/Board: ROI, predictable spend. Show annual savings, break-even point, and long-term value
HR/Operations: Talent access, time-to-hire. Evidence of a wider supplier network and faster fills
Compliance: Audit readiness, risk management. Highlight improved governance and real-time visibility
Procurement: Supplier performance, cost control, contractual efficiency. Demonstrate stronger supplier management, better rates, and transparent reporting
Project Managers: Mobilisation speed. Show reduced delays and faster project delivery

The long-term benefits of a 2nd Gen MSP

Your business case should end by showing how a second-generation MSP provider sets the organisation up for future success:

Real-time data for strategic workforce planning
Stronger governance in highly regulated environments
Access to broader supplier networks, including overlooked and under-represented talent pools
Faster project mobilisation, reducing time to value
Continuous improvement, not stagnation
This shifts the decision from a short-term fix to a long-term strategic investment.

A well-structured business case turns the idea of switching MSPs from a reactive decision into a justified, proactive strategy. It helps provide the confidence that your next MSP partnership will deliver greater value.

And when you reach the point of preparing for mobilisation, our MSP Implementation Checklist is a practical tool to help you ask the right questions and ensure your new programme is set up for long-term success.

The Future of Nuclear talent with Nancy Bellingan

Whether it was standing out as the only girl in a physics class of 20 in Italy or driving across Europe to begin a new role in the UK, Nancy Bellingan has built her career by embracing challenges head-on. In episode 6 of Rullion Reflections, Nancy explores the future of nuclear. She explains why education, visibility, and breaking down barriers are just as important as technology in shaping the next generation of nuclear talent. Watch the full Rullion Reflections Ep. 6 interview with Nancy or read on for the key highlights from the conversation. At the cutting edge with Createc Today, Nancy brings her experience to Createc as a Radiation Physicist. Known for pioneering work in nuclear decommissioning, robotics, and 3D radiation mapping, Createc is the kind of environment where no two days look the same. Her journey to the role was as memorable as the work itself. Packing up her life in Germany, she carefully measured her small car to make sure every box would fit, then drove across Europe, through Belgium and the Channel Tunnel, before finally arriving in Cumbria. “It was completely full – I couldn’t have squeezed in another thing,” she laughs. Nancy first connected with Createc at DigiDecom, a digital decommissioning conference, where she was struck by the company’s innovative spirit and by the leadership of Rosie, now one of her colleagues. That chance meeting led to an opportunity, and Nancy quickly knew it was the right fit. “They replied within an hour of my application and offered me the job the next day. That efficiency really stood out, and once I started, I didn’t know I could like a job this much. No two days are ever the same.” Early Inspiration Nancy’s interest in science began early. Growing up in Italy, she often followed in her brother’s footsteps; whether it was rugby, scuba diving, or computer games. When he became interested in nuclear, so did she. But it was role models like Licia Troisi, an astrophysicist and fantasy author from her hometown, who showed her what was possible. “I wanted to be like her: an astrophysicist who also wrote books,” Nancy recalls. “In the end, I only did one part: the nuclear physics.” That mix of curiosity, role models, and resilience meant that being “the only girl in the class” never discouraged her. Instead, it became part of her drive. Nuclear education as the foundation Nancy believes it all begins in the classroom. Too often, the first time young people hear about nuclear is through disasters or sensationalised media. These historic events must not be forgotten, but they should be understood in context, alongside decades of progress in safety, innovation, and regulation that make the nuclear industry what it is today. Nuclear today is one of the most heavily regulated and scrutinised energy sectors in the world, monitored by organisations like the IAEA, ENSREG, and the ONR in the UK, with multiple layers of safety protocols in place to minimise risk. Early nuclear education is one of the best ways to reshape understanding. By introducing nuclear concepts in school science classes, students can see how nuclear is used today as a clean energy source and through its life-saving medical applications. In countries like Belgium and France, nuclear is woven into environmental studies from a young age, creating a more balanced foundation where nuclear is part of education; students grow up seeing it as normal, not controversial. For example, Belgium’s parliament recently voted to drop the phase-out of nuclear energy, extending reactor lifetimes and exploring new builds. And in 2025, France will generate nearly 70% of its electricity from nuclear power. This early education not only helps to shift public opinion but also to show students the vast opportunities available in nuclear careers, helping to bring in the next generation of nuclear talent. Attracting and retaining future of nuclear talent “How can we get more young people into the nuclear industry?” Sibel asks. The irony, Nancy points out, is that even when students choose nuclear pathways, many find the doors closed. Security clearance, nationality restrictions, and slow recruitment processes often block skilled candidates from entering. The result is bright minds drift into other industries, while nuclear struggles to fill the pipeline it desperately needs. Nancy sees the cost of this up close: graduates with the right skills and passion who simply can’t find a way in. It’s not that the talent isn’t there; it’s that the system is too rigid to welcome them. And every missed opportunity is another gap in research and development, another idea never explored, another innovation lost. "I have so many former students who studied nuclear-related subjects and they’re not getting jobs. It’s not that they don’t want to join, it’s that sometimes they’re not let in." To sustain the future of nuclear talent, the industry must turn inspiration into opportunity. That means breaking down barriers, making hiring fit for purpose, and showing students clear and diverse career paths. Without young professionals in the labs, in R&D, in decommissioning, and in innovation, nuclear risks losing momentum in the global energy transition. Belonging and visibility Young people need to see themselves reflected in the industry if they’re going to believe they have a place in it. Representation is as important as technical skill because it shapes who feels welcome to apply in the first place. Nancy believes the key to attracting and retaining talent is visibility: role models across gender, ethnicity, and background. Nuclear should be seen as a place for all kinds of people, across all kinds of roles. What makes this possible is culture. Nancy’s own story highlights the generosity of mentors who opened doors for her, trusted her, and gave her room to grow. That spirit of support and knowledge-sharing is nuclear’s hidden strength and the reason the sector can continually renew itself through each new generation. "We shouldn’t just focus on gender. Diversity should also mean ethnicity, background, language, and culture. Students need role models so they can see it’s possible and then decide for themselves." What is the future of nuclear power? "Nuclear is like sci-fi.” Nancy says. “You don’t invent new jobs; you take existing ones… and put them into the setting of nuclear." Just as sci-fi doesn’t invent entirely new storylines but reimagines them in futuristic settings, nuclear takes existing professions like chemistry, robotics, mechanical engineering, and even HR, and situates them within a unique environment. This perspective reframes nuclear from a niche field to a cross-disciplinary hub where a diverse range of skills can find application. For those outside the industry, it opens the door to consider nuclear not as “other”, but as an extension of their own expertise. Looking Forward The nuclear industry is at a turning point. Perception, education, and diversity aren’t side conversations; they’re the frontline of the future of nuclear talent. If the sector wants to thrive, it must act: Inspire early through education Remove barriers to entry Showcase diversity and belonging Share knowledge openly across generations and borders Nancy’s journey is a reminder that nuclear’s story is still being written. And the next chapter will be defined by the choices the industry makes today. Ready to start your own nuclear career? View our latest nuclear jobs. Watch the full interview.
