Choosing the Right for MSP Delivery Model Your Critical Infrastructure Projects

Why the MSP delivery model matters Your MSP delivery model shapes: Speed – how quickly roles are filled Quality – how well candidates match your requirements Access to talent – how broad or targeted your sourcing is Supplier relationships – how performance is managed Compliance and control – how you meet sector-specific regulations Two of the most widely used MSP vendor models are Master Vendor and Neutral Vendor. Some organisations also use Hybrid approaches. The right choice depends on your skill mix, supply chain maturity, and delivery priorities. Where MSP delivery models overlap No matter which model you choose, your MSP provider should still: Manage the end-to-end process for recruiting and managing contingent workers Act as a single point of contact for hiring managers and procurement Oversee supplier performance, contracts, and regulatory compliance Provide clear reporting, insight, and market intelligence Drive cost control, risk management, and continuous improvement What’s the difference between Master Vendor and Neutral Vendor? The key difference lies in candidate sourcing and supplier prioritisation: Master Vendor: in-scope roles start with the primary supplier’s own network before engaging others Neutral Vendor: opens every role to the full supplier network from day one Master Vendor MSP In a Master Vendor model, your MSP service provider is led by a single primary supplier who fills most requirements (between 60-90%) from their own talent network. When they can’t fill a role, it’s passed to a small group of approved third-party suppliers. When does a Master Vendor MSP works best? High volume of similar roles with quick turnaround times Predictable, repeat skillsets that benefit from direct fulfilment When your primary supplier has deep expertise of your sector and is able to deliver direct fulfilment on in-scope roles Example: A utilities contractor ramping up for a national smart meter installation programme or an energy provider hiring engineers for planned maintenance. Advantages of a Master Vendor model: Faster fulfilment for repeat roles Consistent quality from a supplier that knows your business Streamlined supplier management Risks to manage with a Master Vendor model: Success relies heavily on the strength and sector expertise of the primary supplier’s own network. While a Master Vendor will still work with trusted third-party suppliers for specialist roles, access to ultra-rare or emerging skill sets may still be more limited than in a Neutral Vendor model. Neutral Vendor MSP In a Neutral Vendor model, your MSP service provider acts as an impartial manager. Still overseeing all supplier relationships, enforcing performance standards, and ensuring compliance, but without prioritising its own candidates. All approved suppliers get the same opportunity to submit candidates for each role, creating a level playing field. When does a Neutral Vendor MSP works best? Roles require niche, scarce, or highly specialised skills Broader supplier reach is needed for complex projects Example: A nuclear operator hiring safety case engineers, or a water company recruiting hydrologists and digital infrastructure experts. Advantages of a Neutral Vendor model: Greater reach into niche skill markets Competitive sourcing that can balance speed, cost, and quality Less reliance on a single supplier Risks to manage with a Neutral Vendor model: Potentially slower fulfilment if processes aren’t tightly managed More complex supplier relationship management Hybrid MSP models A Hybrid MSP delivery model blends elements of Master Vendor and Neutral Vendor models to create a more flexible delivery approach. It’s designed to give you the speed and simplicity of direct fulfilment for common roles, while also tapping into a wider supplier network for specialist needs. When does a hybrid MSP vendor model work best? You have a core set of high-volume, repeat roles alongside niche, low-volume requirements. Supply chain maturity varies. Some skill areas are well covered; others need broader reach. Project demand is uneven, with peaks for specific skill sets at certain times. How a hybrid model works in practice: Master Vendor mode for operational or technical roles where the primary MSP supplier already has strong talent pipelines. Neutral Vendor mode for specialist, rare, or project-specific skills where a wider net is needed. Example: A national energy provider may use a Master Vendor approach for meter engineers, field service technicians, and project managers but switch to Neutral Vendor sourcing for cybersecurity experts or nuclear safety specialists. Advantages of a hybrid MSP model: You get the best of both worlds. Fast fulfilment for common roles, wide access for niche needs. Tailored sourcing strategy for each skill area. Can evolve over time as project needs change. Risks to manage with a hybrid model: Requires clear governance and role categorisation so suppliers know when each model applies. More complex performance tracking to ensure both streams are delivering against targets. Master Vendor MSP vs. Neutral Vendor MSP Considerations Master Vendor Model Neutral Vendor Model Speed Faster fulfilment for repeat skills Dependent on supplier responsiveness Access to niche skills Relies on primary supplier’s expertise for in-scope roles and escalation to approved suppliers Immediate access to full approved suppliernetwork Supplier relationship management One dedicated MSP contact managing a smaller, focused supplier group One dedicated MSP contact managing a broader supplier network, ensuring performance, compliance, and consistency across all vendors Cost control Strong for repeat hires Competitive supplier engagement may reduce agency rates Risk Over-reliance on one supplier Possible slower time-to-fill if not managed well Choosing the right MSP model and provider The right MSP delivery model will depend on your current skills mix, supply chain maturity, and delivery priorities. But it shouldn’t stay static; if it does, it could be time to change your MSP provider. Rullion’s MSP model helps organisations evolve their approach over time. Whether that means starting with a Master Vendor model for speed and control, moving toward a Neutral Vendor model to widen reach, or blending the two in a hybrid model.

Are we prepared for the governance needed to manage multiple suppliers?

The ROI of Building Talent Internally

A Train to Deploy strategy offers a smarter, more sustainable way forward. Cost reduction, accelerated readiness, and a workforce designed to meet both today’s demands and tomorrow’s opportunities. Often referred to as a Hire Train Deploy model or Recruit Train Deploy strategy, Train to Deploy (TTD) is a workforce transformation solution that combines bespoke training with targeted deployment. It enables you to source talent based on behaviours and potential, then develop the technical skills your business needs. It’s a scalable workforce solution that delivers tangible ROI and long-term resilience. 1. Direct Cost Savings Lower recruitment spend You invest in readiness, not agency margins. External hiring often comes with hefty costs, agency fees, advertising, multiple interviews, onboarding, and more. And when those hires don’t stick, the cycle starts all over again. TTD reduces recruitment spend and reactive hiring by creating a pipeline of pre-trained, aligned talent. Spend shifts away from repetition and toward lasting capability. Reduced contractor reliance Reduce your dependency on high-cost, short-term fixes. A Train to Deploy strategy lets you build a pipeline of job-ready talent that meets your real-world operational needs. You’re able to scale back short-term or high-cost contingent labour and build talent capacity internally. This gives you more financial flexibility and control over your workforce model. Higher retention rates Investing in the right foundation leads to better long-term outcomes. When candidates are trained specifically for your roles, systems, and culture, they stay longer. With TTD, training is front-loaded and role-specific. People arrive more confident, capable, and connected to your purpose. That leads to lower attrition, less churn, and reduced hiring costs over time. 2. Value Beyond the Bottom Line Faster onboarding, faster productivity One of the biggest hidden costs in recruitment is lost time: the two-month ramp-up, the slow integration, the inconsistent onboarding. Our Train to Deploy solution shortens that curve. With role-specific onboarding delivered in advance, new hires contribute faster, helping you unlock value from day one. Inclusive hiring, by design Traditional hiring filters often exclude great candidates who don’t match a perfect CV. TTD is built around a behaviour-first approach. If someone has the right mindset and potential, Rullion helps develop the skillset, regardless of background, career history, or qualifications. We call it inclusion without limits. And it helps organisations build community-reflective, inclusive talent pipelines that improve DEI metrics and culture, without compromising on quality or readiness. Higher engagement and performance When people feel prepared, supported, and set up for success, they thrive. X helps turn every new hire into a high-potential one. By nurturing confidence early and delivering job-specific training up front, it supports stronger retention, better collaboration, and more engaged, high-performing teams. That means better value per headcount and a stronger culture. 3. Future-Proofing the Workforce Building skills before you need them Whether you’re preparing for an infrastructure expansion, facing a retirement cliff, or adopting new technologies, a Train to Deploy solution helps you build skills in advance. By aligning talent development to your strategic goals, you’re never caught short when demand shifts. It’s one of the key benefits of Train to Deploy, enabling you to grow capability at pace with opportunity. Built-in resilience Organisations that build from within are better equipped to handle evolving industry or project landscapes. A Train to Deploy model gives you the agility to scale teams, adopt new technologies, or respond to regulatory shifts. With a workforce already trained and aligned. The ROI of Train to Deploy is beyond just pounds saved; it’s in adaptability gained. Institutional knowledge transfer By redeploying contractors or training new hires to shadow outgoing specialists, a Train to Deploy framework helps retain hard-won expertise that might otherwise walk out the door. This workforce transformation strategy makes sure knowledge transfer is captured through structured training and handovers. It protects institutional knowledge, safeguards IP, and ensures continuity during transitions. The ROI Goes Deeper Than Cost Yes, Train to Deploy delivers tangible cost savings. It also transforms how your organisation functions. This long-term workforce transformation is where the true ROI of Train to Deploy is realised: in cost, capability, and culture. When you invest in internal capability, you don’t just plug gaps. You shift from reactive hiring to future-fit teams. You create a workforce that reflects where your business is today and where it’s going. Want to see how Train to Deploy could deliver ROI for your organisation?
