Thank you for your interest in working in Defence Digital Commercial.

Lee RimmerDefence Digital Commercial is a department of the Ministry of Defence (MOD)  staffed, at a senior level, by employees from the Government Commercial  Organisation (GCO). It is one of the largest  and most complex commercial  functions within Government evolving into a Category Management structure  covering Networks, Hardware and Services, Software, Military Technology and  Professional  Services, managing  contracts that are so huge it is not  unreasonable to consider that they may be impossible to manage effectively. We  have a very attractive and exciting portfolio of opportunities to offer technology  suppliers, making this a very exciting employment opportunity. We need to grow our teams now to meet the heavier technology demands of the MOD which in turn means a significant increase in our commercial activity.

The most powerful thing any commercial department can have is the ability to  have a strong client relationship combined with a collaborative alignment with  commercial colleagues. It is therefore my goal to ensure that the correct people  are employed in this department adding value and help shape our strategic  approach to the buying of technology and technology services for the MOD.

Lee Rimmer - Defence Digital Commercial Director

Building a strong Commercial Function in Government, and with it the right  commercial capability, is at the heart of a far‐reaching programme of Civil  Service reform.

The Government Commercial Function is more than just the response to the  challenges that Government has faced in recent times; it is an essential element  of the Government’s efforts to address the value for money  agenda, while  delivering higher quality public services.

Our vision is to make the Government’s Commercial Function the best in the UK:  staffed with top commercial specialists, creating  and managing innovative,  efficient and effective commercial arrangements. This is an exciting and diverse  environment – we spend around £49bn per year on procurements that range
from £100k to multi-billion-pound contracts, with annual spend on individual  contracts often exceeding £500m. Our supply base includes  SMEs and the  largest multinationals, and our business models have the Government acting as
shareholder or sponsor, as well as being an ‘intelligent client’.

I hope you will be inspired to join us and help lead the ongoing commercial  reform agenda of the Civil Service. You won’t find a more exciting or diverse  challenge elsewhere.

Background to the Government Commercial Function

workerThe Civil Service is one of the biggest and most complex employers in the UK, employing over 400,000 Civil Servants, serving both Ministers and the public, to deliver the priorities of the Government of the day. These include major projects with a lifecycle cost of around £500bn, as well as programmes and services that affect everyone in the United Kingdom. The annual spend is c. £49bn per annum with a range of suppliers including SMEs.

Following issues with some major contracts and key suppliers, the Civil Service has committed to dramatically improving its commercial performance. This has included establishing a Commercial Function that will operate with, and in support of, departments. A senior Government Chief Commercial Officer was appointed from the private sector to head up the Commercial Function. This coincided with the first set of Commercial Standards published for Government in February 2016, updated in November 2016 which we now benchmark against.

Commercial resources overseen by the function number some 4,000 staff across Whitehall, and consist of:

  • Several core interlocking central teams working together on Policy, Standards and Continuous Improvement, Complex Transactions, Markets and Suppliers (that will build pan-­Government relationships with key suppliers) and Commercial Capability
  • Colleagues in the Commercial Directorates within Departments and Agencies
  • The Crown Commercial Service, a trading fund sourcing common goods and services for the Civil Service and the wider public sector, managing spend of circa £13bn

The Commercial Function is led by Gareth Rhys Williams, the Government Chief Commercial Officer (GCCO). He reports directly to the Chief Operating Officer of the Civil Service, Alex Chisolm.

We operate across five categories – Networks, Hardware and Services, Military Technology, Software and Hosting and Professional Services - engaging with suppliers of all sizes and specialisms across the technology and defence landscape aiming to reduce third-party costs and ensure tax-payer value. 

Our wide-ranging Strategic Supplier Management programme is building a centre of commercial excellence, with a team of almost 200 people focussed on getting the most financially astute outcomes across all our contracts.

We’re looking for articulate, proactive, and experienced people who thrive on complex challenges, who understand how their specialist knowledge will contribute to the strategic outcome, and who will bring value to our established team of professionals.

The team is constructing its own framework for IT and Professional Services which will go-live in early 2022. The vast majority of Professional Services requirements will be sourced through this new framework to give better data and pricing and improving knowledge and relationships in the market-place.
