The first full draft, in hours

Scoping documents and the evidence base go in, and a structured draft comes back the same day.

Senior time on judgement

Your economists spend the commission on assumptions, sensitivities and the review conversation rather than assembling the document.

Your name on the report

Output arrives in your house template, and sign-off and ownership stay with your team.

Procurement-ready assurance

UK and EEA processing, a separate deployment per customer, and no training on your documents.

GAIA's opening screen: the procurement spend selects the business case template, and source documents are uploaded alongside
The spend sets the template, and the scoping documents go straight in.

Coverage

The Five Case Model.

GAIA drafts all five cases of a business case. The strategic and economic cases are appraised in full; the rest are drafted from what your documents state.

  1. Strategic Appraised

    The case for change, objectives, and the benefits, risks and dependencies, appraised by GAIA's economist agent.

  2. Economic Appraised

    Longlist and shortlist appraisal, social cost-benefit analysis against government datasets, optimism bias, and sensitivities.

  3. Commercial Extracted

    Procurement strategy, risk allocation, and contractual arrangements.

  4. Financial Extracted

    Budgeting and accounting treatment, funding, and contingency.

  5. Management Extracted

    Governance, delivery, benefits and risk management, monitoring and evaluation.

Extracted cases are drafted from your source documents. Where those are silent, GAIA marks the gap for your team to complete rather than inventing content.
