Accelerating Delivery Efficiency In Defence by Removing Waste

In the defence industry, programme delivery often operates in a high-stakes environment with significant financial and operational constraints. Time is one of the most critical factors in these scenarios, directly correlating to labour costs and overall budget adherence. This case study demonstrates how focusing on removing waste from delivery processes saved time and reduced costs in a large-scale missile programme, enabling alignment with strict timelines and budgetary expectations.

Inefficiencies in Delivery Processes

The programme’s delivery cycle faced significant challenges due to systemic inefficiencies embedded in traditional waterfall methodologies, siloed team structures, and extensive context-switching. These inefficiencies translated into repetitive work, prolonged feedback loops, and decision-making delays, all of which contributed to escalating labour costs without delivering proportional value. Siloed teams with limited collaboration exacerbated bottlenecks, while rigid governance frameworks hampered adaptability and slowed project progress. As labour costs climbed due to extended timelines, the project faced risks of missing critical deadlines and exceeding its budget. Stakeholders demanded immediate solutions to address these inefficiencies, underscoring the need for transformative change to avoid jeopardising the programme's success.

The Cost of Inaction

Without decisive action, the inefficiencies within the delivery framework threatened to derail the entire programme. Each day of delay compounded financial pressures, eroding funds allocated for other critical projects. Beyond monetary costs, the delays posed serious risks to operational readiness, leaving the end-users—armed forces—without crucial capabilities in a rapidly evolving geopolitical landscape. Prolonged inaction risked reputational damage and diminished trust among stakeholders, forcing the organisation to confront a stark choice: persist with entrenched practices or embrace transformative change to overhaul its delivery processes.

Driving Change with Targeted Actions

The organisation’s transformation began with the adoption of Value Stream Mapping (VSM). However, the focus was not on running the VSM itself but on the actionable insights it generated. Teams used the VSM process to identify bottlenecks and waste, and then translated these findings into a prioritised set of interventions. These actions formed the foundation for eliminating inefficiencies and enhancing value delivery across the programme.

Siloed teams were restructured into cross-functional groups aligned to end-to-end delivery, fostering collaboration and accelerating progress by breaking down long-standing barriers. Delivery methods evolved into a hybrid agile framework that combined iterative and incremental practices. This approach prioritised high-value work and created shorter feedback loops, which enabled teams to adjust quickly to new information and minimise rework. Agile governance mechanisms replaced rigid, traditional controls. Transparent dashboards highlighted impediments, driving their proactive removal and accelerating decision-making.

Tangible Cost and Time Savings

The impact of these interventions was significant and measurable. By translating insights from VSM into decisive actions, the programme reduced cycle times by 22% within two years, allowing teams to meet critical milestones earlier than expected. Labour costs were significantly reduced, saving an estimated £10M over the same period by eliminating wasteful practices and optimising resource utilisation. Faster delivery cycles improved stakeholder satisfaction, fostering stronger partnerships and trust. Beyond these measurable outcomes, the cultural transformation within teams enabled a mindset of continuous improvement, ensuring that the benefits extended beyond the immediate programme.

Delivering Long-Term Value

This case study underscores the importance of focusing on actionable outcomes rather than process for its own sake. By leveraging the insights generated through VSM and committing to implementing the resulting actions, the organisation achieved a significant reduction in both time and costs. These results not only ensured the success of the programme but also created a repeatable framework for sustained delivery excellence.

To build on this momentum, the organisation can extend agile practices to other programmes, institutionalise action-driven VSM workshops as a standard delivery tool, and invest in leadership development to embed a culture of efficiency and innovation. By continuing to prioritise actions over processes, the organisation is well-positioned to lead the defence sector in operational excellence and strategic impact.
