Experience that brings both sides of the market together

I am a senior commercial and digital transformation executive with more than 35 years’ experience across UK Government, defence, technology, telecommunications and aviation.

Most recently, I was Commercial Director for Defence Digital within the UK Ministry of Defence, with direct responsibility for approximately £2.4bn of annual digital spend and category strategy responsibility for a further £2bn across Defence.

My experience covers commercial strategy, digital and technology procurement, strategic sourcing, IT outsourcing and managed services, enterprise software, supplier relationship management, category management and commercial operating model transformation.

I have extensive first-hand experience of the UK Government and Defence technology markets, including how major technology programmes are procured, evaluated, negotiated, contracted and governed.

I have worked closely with major systems integrators, technology vendors and specialist suppliers, and have led initiatives to improve supplier engagement, competition and collaboration.

At Defence Digital, this included major contract disaggregation, satellite PFI exit, MOD-wide enterprise software arrangements and the creation of a supplier Collaboration Code of Practice involving more than 130 suppliers and techUK.

I can provide insight from both the buyer and supplier perspectives, having previously held senior European and EMEA commercial and procurement leadership positions with HCL, CSC and Level 3 Communications.

My particular areas of expertise include UK Defence and Government procurement, Defence Digital, commercial strategy, digital transformation, IT services and outsourcing, technology sourcing, supplier strategy, category management, operating model design, commercial assurance and procurement transformation.

I have led large-scale organisational transformations, acquisition integration and complex commercial negotiations, including delivering £1.6bn of measured savings within Defence and substantial savings across global technology organisations.

I am particularly well placed to advise on the UK public sector technology market, procurement and commercial models, supplier competitive positioning, market dynamics, major digital transformation programmes and the practical considerations involved in selling technology and services into UK Government and Defence.
