How We Can Help

We help our clients to refine and improve projects by preparing business cases, which often support applications for public funding for projects. Our Green Book compliant business cases – following principles set out by HM Treasury – include setting out the five strategic, economic, financial, commercial, and management cases. Our business case work has covered:

  • Urban regeneration schemes
  • Public realm improvements
  • Digital infrastructure upgrades
  • Public transport improvements
  • Innovation and enterprise centres
  • Flexible workspaces

The Importance of a Strong Business Case

Projects are far more likely to deliver their intended outcomes and benefits when properly scoped, planned, and costed from the outset. Preparation of a business case using the five case model provides decision makers and stakeholders with assurances that, based on structured thinking within a proven framework, a project:

  • Provides strategic fit and is underpinned by a compelling case for change;
  • Maximises social value by choosing the best combination of components and products;
  • Is commercially viable and attractive;
  • Is affordable and fundable in a sustainable manner; and
  • Can be successfully delivered by an organisation and its partners.

Our Approach

As part of our business case preparation we follow the Green Book’s Five Case Model:

  • Strategic case: project background and rationale; alignment to key local and national policies; the projects SMART objectives; outputs and outcomes; evidence of market failure, how the project will tackle it, and what will happen without the intervention; key beneficiaries; views of key stakeholders; and dependencies, constraints and risks.
  • Economic case: long list of options considered, and shortlist; options appraisal; Benefit to Cost ratios for all options, including additionality calculation of all benefits, application of optimism bias, and use of net present values; sensitivity analysis; and management of dependencies, constraints and risks.
  • Commercial case: market and commercial demand for the project; viability and deliverability of the project; procurement; contract management; delivery model; and risks identified, allocated and managed.
  • Financial case: Capital and revenue costs; funding sources; project affordability; contingencies; operating costs and financial sustainability; financial risks.
  • Management case: governance and management; track record; delivery programme; risk register; contingency plan; permissions; monitoring and evaluation; benefits register; stakeholder management strategy.
