Why a Behaviour-First Train to Deploy Strategy Builds Stronger Workforces

BLOGBy Rullion on 20 August 2025

Most failed hires don’t fail due to missing skills, they fail due to poor fit. In critical sectors, the right Train to Deploy strategy reduces that risk and builds stronger teams.

This insight draws on our Confessions of a Train to Deploy Expert series, where Dan Crerand, Rullion’s Train to Deploy Director, sits down with Sibel Akel, Rullion’s Marketing Director, to explore why behaviour-first hiring unlocks overlooked talent, strengthens diversity, and builds long-term workforce resilience.

In episode two of Confessions of a Train to Deploy Expert, Rullion’s Dan Crerand (Train to Deploy Director) and Sibel Akel (Marketing Director) discuss why so many “failed hires” aren’t down to missing skills, but to poor behavioural and cultural fit. Drawing on Dan’s experience delivering Train to Deploy programmes in critical infrastructure, they explore how a behaviour-first approach helps employers uncover overlooked talent and build stronger, more diverse teams.

Rullion is a workforce solutions provider specialising in regulated and technical sectors across the UK and Europe, helping organisations shift from reactive hiring to long-term workforce strategies. Through solutions like Train to Deploy (TTD), we help organisations move from reactive hiring to long-term workforce strategies, creating talent pipelines built around real roles and values.

Why Behaviour-First Train to Deploy Programmes Matter Now

Critical infrastructure organisations face workforce challenges that aren’t going away. Skills shortages are structural, not temporary. An ageing workforce, declining enrolment in vocational pathways, and rising demand for regulated technical skills are all putting delivery at risk.

That’s why many employers are exploring Train to Deploy strategies. Unlike generic Hire Train Deploy or Recruit Train Deploy models offered by other suppliers, Rullion’s approach flips the order: behaviours and values first, technical skills second.

As Dan Crerand explains:

“Job specs are often shopping lists of everything a hiring manager could dream of. You’re asking for unicorns, and excluding great people. Start small. Change one role, one spec. Prove it works. Success stories travel fast inside organisations.”

The Talent That Gets Missed

Traditional recruitment often screens out the very people who could thrive in technical roles. Ex-athletes with years of discipline, parents returning to work with resilience and adaptability, people with disabilities who bring determination, or early-career candidates with creativity and drive - all too often overlooked.

Dan traces his philosophy back to a decade:

“I started working with underrepresented groups and saw so much potential being missed. I wanted to help clients grow their own talent. That’s where it all started.”

These individuals may lack the “perfect CV” or polish in interviews, but they bring the resilience, adaptability, and learning agility that underpin long-term success. Traditional recruitment screens them out. A behaviour-first Train to Deploy strategy screens them in.

Why Behaviour Matters More Than Skills

Research shows that 46% of new hires fail within 18 months, and almost 90% of those failures are due to poor behavioural or cultural fit - not technical skills.

For critical infrastructure organisations, that failure rate means wasted time, repeated recruitment cycles, and delivery risks that quickly escalate into cost overruns.

Dan’s work with athletes illustrates the point: people who had been waking at 5am for years to train displayed discipline, timekeeping, and resilience far beyond what a CV could show. Without behaviour-first hiring, this potential would remain hidden.

“I spoke to people who had been getting up at 5am for 15 years to train. Their discipline, resilience, and timekeeping were outstanding. But how does an ex-gymnast or high jumper showcase that in a CV? They’re just another name in an applicant tracking system. Recruiters can’t see it, and the industry loses out.”

Behaviour-first hiring brings that hidden potential into view.

Inside Rullion’s Behaviour-First Train to Deploy Strategy

Rullion’s Train to Deploy solution reverses the order. Train to Deploy isn’t a one-size-fits-all bootcamp. Unlike traditional hire-train-deploy providers, it’s built around your roles and your culture. Our TTD services assess behaviours first, then design training pathways for the exact technical and regulatory skills you need.

The model includes:

Behaviour-led screening via psychometrics and structured interviews

Mutual selection, where candidates and organisations evaluate each other

Tailored training aligned to your technical and regulatory needs

Inclusive pipelines that bring in returners, early-career talent, and people from non-traditional backgrounds

Benefits for Employers

Unlike generic Hire Train Deploy or Recruit Train Deploy models, Rullion’s Train to Deploy programmes are built around role-specific needs. Our TTD services go beyond training, they’re about long-term outcomes. As one of the UK’s leading Train to Deploy suppliers, we help organisations reduce churn, scale delivery, and meet compliance requirements in critical environments.

With Train to Deploy, organisations gain:

Faster deployment into critical roles

Lower hiring risk through behaviour-first selection

Inclusive, diverse talent pipelines

Improved retention and long-term capability uplift

Commercial flexibility vs contingent labour

Stronger Teams Through Diversity

Behaviour-first hiring doesn’t just fill vacancies, it reshapes teams. One digital services client initially resisted hiring non-traditional candidates, but after a trial, saw improved creativity and performance across the team.

Another leader deliberately brought in behaviour-first candidates every year to diversify his workforce. Over time, he noticed “reverse mentoring” emerge; juniors energising seniors, while seniors passed down knowledge in return. The whole team became stronger.

That’s the multiplier effect of Train to Deploy.

From Overlooked Potential to Future Workforce

Under pressure, it’s tempting to hire quickly for technical capability alone. But short-term fixes rarely last. Hiring someone misaligned to your organisation’s values often means revisiting the same role within months.

Dan recalls introducing behaviour-first hiring in the digital sector. Some leaders doubted whether candidates from non-traditional backgrounds could perform. But after one trial, the client saw how a candidate with resilience and drive could rapidly add value once trained. It marked the start of a mindset shift: skills can be trained, behaviours cannot.

Why Not In-House?

Some employers ask if they could replicate this internally. The reality? Most HR and L&D teams don’t have the capacity to design behaviour-first assessments, manage external training providers, and deliver wellbeing support at scale.

Rullion carries that load, while clients stay in control of outcomes. This allows internal teams to focus on delivery while gaining faster deployment, better retention, and long-term workforce stability.

Choosing the Right Train to Deploy Supplier

Behaviour-first hiring isn’t a quick fix. It’s a long-term workforce strategy that helps organisations unlock overlooked talent, strengthen diversity, and build resilience.

BPSS Clearance: A Smarter Approach to Background Screening

“What exactly is BPSS clearance, and why is it such a big deal for places like Hinkley Point C or Sizewell C?” Sibel asked at the start of our latest Confessions of a Screening Expert conversation. It’s a good question. For many businesses stepping into regulated environments for the first time, Baseline Personnel Security Standard (BPSS) checks can feel like a maze of acronyms and requirements. But for Jayne Lee, Candidate Services at Rullion, BPSS is the baseline that keeps projects moving, and people safe. What BPSS Clearance Involves BPSS is the government framework for initial background screening. Jayne describes it as “the baseline of where people need to be cleared to.” It includes: Right to Work check Identity verification Criminal record check (DBS checks) Three years of employment referencing “People sometimes call it the ‘RICE’ model,” Jayne adds. “Right to Work, Identity, Criminal record, and Employment history. It’s a clear structure, and it’s widely recognised as the entry-level clearance for high-security roles.” From there, some roles may require higher levels of clearance (like SC or DV), but BPSS is always the starting point. And while it’s critical at nuclear sites like Hinkley Point C and Sizewell C, BPSS clearance is increasingly required across other regulated sectors too, including rail, energy, and utilities. The Challenge: Speed Without Compromise At projects like Hinkley Point C and Sizewell C, every worker - from engineers to ground staff - must hold valid BPSS clearance before stepping on site. Delays here can stall entire workstreams. The industry norm for completing BPSS checks is often 30–40 days. For major infrastructure projects, that’s simply not sustainable. Rullion’s solution: Jayne’s team achieves an average of 7.5 days per clearance. In exceptional cases, they’ve turned around a check in just 24-hours. But it’s not just about speed for speed’s sake. “When you scale up, challenges appear,” Jayne explains. “Last summer we onboarded over 1,000 international workers in one intake. International criminal record checks can push timelines out, but even then, our average was around 15 days — still significantly faster than sector norms.” Read how we deliver screening success at Hinkley Point C and Sizewell C › and see how our approach to BPSS clearance is keeping projects on track while reducing delays across complex supply chains. More Than a System: People First 'Where does this speed come from?' asks Sibel. According to Jayne, it’s the human-led approach that makes the real difference. Before any link or form is sent, every candidate receives a call from a named advisor. “That first call is golden,” says Jayne. “We introduce ourselves, explain the process step by step, and make sure candidates know what documents they’ll need. If they’ve got everything ready, the process sails through.” This proactive support avoids delays caused by missing documents or incomplete forms. And it doesn’t end there: Candidates have a direct phone number and email for their advisor. Clients get weekly catch-up calls to resolve issues quickly. No one is left waiting on a generic helpdesk or traffic-light status update. “It’s not just about compliance,” Jayne adds. “It’s about building trust and momentum.” Where Technology Fits In It’s not all down to people. Smart technology underpins the process, helping keep everything secure, visible, and moving at pace. For candidates, that means a smoother journey with less waiting around. For clients, it means instant oversight of their workforce, so they know exactly where things stand. “It’s the combination that works,” Jayne explains. “Automation helps with speed, but human oversight ensures accuracy, engagement, and problem-solving along the way.” Common Challenges, Clear Solutions Every project has its hurdles. This approach balances governance, compliance, and candidate experience all without sacrificing speed. Jayne outlines a few common ones, and how her team resolves them: Challenge Solution Candidates are slow to provide documents. Early preparation calls mean candidates know exactly what to have ready. International workers require overseas checks. Dedicated advisors manage timelines and keep clients informed, so expectations are clear. Clients worry about visibility. The portal and weekly calls ensure full transparency at every stage. Final Word from the Screening Expert Jayne has spent over 13 years in background screening. Her verdict? “BPSS clearance isn’t just a box to tick. Done right, it’s what keeps projects moving and candidates engaged. It’s about being quick, yes - but also accurate, compliant, and supportive. That’s where the human element really matters.” For organisations, the key takeaway is clear: background screening services are most effective when they combine smart technology with a human touch. This article is part of the Confessions of a Screening Expert series, where Sibel Akel, Marketing Director at Rullion, speaks with Jayne Lee and other industry leaders about the realities of screening in regulated sectors.

Delivering Proven Screening Success at Hinkley Point C and Sizewell C

Rullion has been a trusted candidate background screening provider since 2014, playing a vital role in supporting major UK nuclear infrastructure projects, including Hinkley Point C and Sizewell C. Working across multiple delivery partners and project phases, we’ve helped embed consistent, compliant, and candidate-friendly screening at scale. With over 8,000 candidates screened annually and clearance times reduced to an average of just 7.5 days, our model continues to support project momentum and onboarding efficiency - while maintaining the highest standards of compliance and governance. The Challenge To keep momentum on projects of this scale, pre-employment screening must be robust, accurate, and fast. Every individual working on site requires BPSS (Baseline Personnel Security Standard) clearance before work can begin. With multiple stakeholders, evolving regulatory requirements, and high volumes of candidates, the background screening process can be complex to manage, even with established systems in place. Our clients needed a nuclear screening provider who could bring clarity, consistency, and pace to an already demanding environment. What project teams need: Timely and accurate delivery of BPSS clearance and related vetting checks A positive, well-supported candidate experience Screening support delivered direct to projects like Hinkley Point C and Sizewell C, and across Tier 1 contractors and their supply chains Real-time visibility, control, and governance in screening processes Tier 1 contractors are the principal delivery partners on major projects such as Hinkley Point C and Sizewell C. Supporting them means enabling their workforces and suppliers to clear vetting efficiently, reducing risk of onboarding delays. A Proven Screening Model for Nuclear Environments Our nuclear screening model has evolved over years of delivery, working across early careers, agency-supplied workers, and permanent hires. The service model is grounded in best practice, with compliance and candidate experience at its core. Our solution is built on five key pillars: 1. Speed with Precision We consistently reduce average BPSS clearance times from 30-40 days to fewer than 8 days, using: A dedicated screening portal with automated timelines Electronic document collection via DocuSign One-to-one support from trained candidate advisors “We’re consistently achieving clearances in 7–8 days - and in urgent cases, we’ve turned around checks in just 24 hours,” says Jayne Lee, Head of Screening. 2. BPSS and Beyond We manage all core BPSS clearance elements: Right to work (RTW) Identity and address verification Criminal record checks (DBS) Three to five years referencing We also support CTC and SC clearance preparation where needed, compiling candidate packs ready for formal review. 3. Human-Led Candidate Experience Every candidate is assigned a named advisor who supports them through the screening journey; they answer questions, collect documents, and maintain engagement from start to finish. “We know how to reach the right contact for a reference. Our proactive approach keeps things moving,” adds Jayne. 4. Real-Time Governance Our clients benefit from full transparency throughout: Live dashboards and candidate status tracking SLA-based monitoring and escalation Monthly reporting and governance in screening audits 5. Scalable Across Supply Chains Our solution is used not only by project leads but by Tier 1 contractors across both Hinkley Point C and Sizewell C. The model scales to support different business units and workforce types including; contractors, agency workers, and permanent staff Impact to Date Over 8,000 candidates screened annually 75% reduction in average screening times +69 Net Promoter Score (NPS) from screened candidates BPSS compliance embedded with live audit capability Fully digital, mobile-friendly experience Adopted by Tier 1s across the project supply chain A Benchmark for Nuclear Screening Rullion’s screening model is now a recognised example of best practice in regulated environments, supporting complex infrastructure programmes where delays and drop-offs can have significant impact. We continue to support project teams across Hinkley Point C and Sizewell C, delivering the confidence and control they need to move quickly and compliantly.
