Our client was going through a major transformation, of which their supply chain was a key focus area. As part of this programme, the client was assessing various options for its operating model and needed to understand whether they could find alternatives for the delivery of some key internal services rather than risk large numbers of redundancies which could lead to a negative impact on the socio-economics of the region.

Proxima was engaged to provide commercial and operational challenge in the development of a business case to consider the commercialisation of some of these key services; offering expertise as a service to similar organisations many of whom would be facing the same challenges in coming years.

The business case would need to explore the creation of a joint venture with a private sector organisation. The client sought to rigorously test whether a private sector organisation could help them exploit their intellectual property to create a revenue stream to support a new joint venture business.

Our Approach

Utilising the principles from the HM Treasury Green Book, we developed a set of business cases to explore with the client and their parent company’s governance process. Over a 12 month period, we worked closely within an internal working group consisting of representatives from across the business and Proxima consultants.

In numerous collaboration sessions we facilitated open critique and challenge to the proposed approach and course correct as needed. We initiated 2 rounds of soft market engagement to test the market’s understanding of the proposition and to test the commercial and operational construct.

In collaboration with the client team, we designed a set of strategic objectives which formed the basis of our analysis. The initial long list of potential options, using the current state as the baseline, included traditional outsourcing models, incorporated & unincorporated joint ventures and subsidiary models. These were thoroughly tested through the economic appraisal and were then balanced by removing any optimism bias and sensitivity analysis to find the ideal solution to take forward.

Outcomes and Deliverables

We jointly produced a detailed 160+ page Outline Business Case (OBC) using the 5 case HM Treasury Green Book model, provided detailed analysis and proposed recommendations to the board. A number of subsequent iterations were worked up for various audiences around the organisation and the parent organisation, as the model developed traction.

Board approval was given to the OBC with a request made to take the proposition formally out to the market under an OJEU procurement. Due to the scale and complexity of the proposition, the OBC was then taken up through the governance process before going to a BEIS Minister for final approval.

This was groundbreaking and game changing in the industry, and for the commercial function.
