The scale and complexity of modern defence programmes means no single organisation can deliver alone. Increasingly, success depends on alliances that bring together government, industry, primes, SMEs and technology partners to deliver critical capabilities.​

But while partnership has become the model, making it work is far from straightforward.​

In this conversation, Q5’s Helena Simister and Joel Grundy explore what separates high-performing alliances from those that struggle. They discuss why successful partnerships are built on more than contracts and governance, and why leadership, culture and trust are becoming just as important as technical excellence.​

The discussion also explores some of the practical challenges organisations face as defence delivery evolves, from integrating new entrants and specialist suppliers, to balancing long-term capability programmes with the need for greater pace, agility and innovation.​

Drawing on Q5’s experience supporting complex defence programmes, Helena and Joel share their perspectives on the behaviours, operating models and leadership approaches that enable organisations to collaborate effectively in increasingly complex environments.​

Whether you’re leading a major programme, shaping a new partnership or thinking about the future of defence delivery, this conversation offers practical insights into what it takes to build alliances that can adapt, perform and deliver lasting outcomes.​

Watch the full conversation below to hear Helena and Joel discuss the opportunities and challenges shaping the future of alliance delivery in defence.
