Background
Sellafield had never previously documented and gained executive-level approval for a desired future state of Continuous Improvement (CI). However, this has now been addressed with the introduction of the Sellafield Way.
A Voice of the Customer (VoC) exercise highlighted the necessity for a Lean Leader programme. When asked, "What can the central Business Improvement (BI) team do to help create a culture of CI?", the predominant response was that leaders needed to be educated in CI to engage and empower their teams in fostering a CI culture.
Feedback from attendees of the LCS 1a, 1b, and 1c training programmes indicated that their leadership teams were not sufficiently focused on developing a CI culture. Although the LCS training, along with Practical Problem-Solving training, standard use of A3 reports, and embedding daily performance meetings, had created a solid foundation for CI, there had been no dedicated training for senior management and the Executive team—approximately 150 individuals.
It was recognised that leaders across the organisation participated in various courses and programmes to develop leadership skills. However, none of these initiatives explicitly focused on the behaviours required to create and sustain a CI culture.
Additionally, there was an awareness of the evolving nature of the business and its mission. Potential funding and resourcing challenges necessitated improved performance, not only for the benefit of Sellafield but also for the wider NDA group. Consequently, a Lean Leader programme was deemed essential to enable widespread contribution to improvement efforts while ensuring that systems and processes were fully aligned.
Activity
Following extensive stakeholder engagement and collaboration with delivery partners S A Partners, the programme structure was established. It consists of an initial benchmarking visit, six days of classroom learning, and five executive coaching sessions. Each participant also completes a VoicePrint exercise, submits an improvement plan for their area aligned with the Sellafield Way, and develops a strategy to sustain the CI culture within their area over a 3-5 year period. Successful completion of the programme leads to LCS 2a accreditation.
A ‘plan on a page’ document was created, outlining the seven key steps taken, the findings from each stage, and the tools utilised. At each stage, the Plan-Do-Check-Act (PDCA) cycle was followed to mitigate risks, maintain compliance, and enhance customer experience while ensuring that stakeholders remained well-informed of progress.
Throughout the programme, the approach was adjusted as required. Due to extensive stakeholder engagement, feedback from multiple sources was consistently incorporated, allowing for flexibility in response to emerging challenges while maintaining focus on the long-term vision.
The strategy developed seeks to establish alignment across teams and functions, drive engagement at all levels, and provide a clear, actionable path forward.

The Impact
The pilot phase, consisting of three cohorts (31 senior leaders and Executive members), was delivered between January and June 2024.
A review of the pilot demonstrated that attendees valued the programme’s content and coaching sessions, with many reporting that it had fundamentally changed their perspective on their roles. Several participants implemented immediate changes as a result of their learning.
The CEO’s mantra—"Every Day Matters, Every Voice Counts"—was incorporated into the Sellafield Way model. Each cohort participates in an out-brief session with the CEO, where they present the results of their Sellafield Way maturity self-assessments. These self-assessments are then compared to deep-dive assessments of their areas, with any identified gaps forming part of an overall improvement plan. This ensures continued embedding of the Sellafield Way and sustained cultural change.
Following the success of the pilot, the Executive sponsor approved a full rollout of the programme. To date, 31 leaders have completed the full programme, with a further 36 currently in progress. Five leaders have already achieved formal LCS 2a certification, with this number expected to rise to 33 by the end of March 2025. Over the course of 2025, it is anticipated that the entire Executive team and the B2/PCH community will have completed the programme.
The current Net Promoter Score (NPS) for the programme is +81, which is considered world-class.
Sellafield looks forward to working with its Lean Leaders to embed Lean as a way of life across the organisation.
