™What could this
really cost?
Examine whole-life costs, annual profiles and the range of risk outcomes alongside the central estimate.
For HM Treasury business cases
The whole case.
A clearer view.
For UK government departments and public bodies preparing business cases for HM Treasury funding and needing to adhere to the Green Book and Orange Book.
Connect cost, risk and schedule analysis to support appraisal, risk management and the evidence behind your decisions.
Supporting all five cases: Strategic, Economic, Commercial, Financial and Management.

The Einro approach
One journey.
Connected throughout.
A cost estimate is only part of the picture. Einro brings the model, the delivery plan and the assurance into the same conversation—so the evidence can be understood together.
Build a shared analytical basis.
Define the project context, model whole-life costs and risks in ATLAS, and import a schedule to align the work with the cost. Capture the source evidence and assumptions as you build.
- Economic assumptions, financial profiles and option comparison
- Built in Monte Carlo simulation and cost uncertainty
- Schedule import and cost alignment
From the source assumptions to the range of possible outcomes.

Challenge what drives the result.
Look beyond the headline estimate. Review data readiness, examine optimism bias and see how cost and schedule assumptions affect the outcome.
- Feeder model verification and validation
- Optimism bias and mitigation assessment
- Cost and schedule sensitivity, and DCMA 14-point checks
Clear findings help teams focus their review effort.

Automate the report. Connect the evidence.
Automatically create reports from captured project context, analytical outputs and assurance findings. Keep a golden thread from source evidence to the options, uncertainty and decisions presented for review.
- Cost and risk results across options
- Schedule and assurance outputs in context
- Evidence to support business-case review

Better questions.
Better-informed decisions.
For analysts, finance teams, project delivery professionals and reviewers who need to understand what sits behind the numbers.
What could this
What happens if
the plan changes?
Connect activities and costs, then explore the schedule drivers that move the project finish.
What needs
closer scrutiny?
Use sensitivity and assurance findings to identify the assumptions and evidence that deserve attention.
Public money. Clear reasoning.
Support for all
five cases.
Einro supports all five cases of HM Treasury’s Five Case Model, bringing project context, analysis and assurance together from SOC through OBC to FBC.
Strategic case
Capture the project context, objectives, strategic fit and stakeholders to support a clear case for change.
Economic case
Compare options using whole-life costs, risk analysis, optimism bias and sensitivity to inform the value-for-money assessment.
Commercial case
Record procurement context and use cost, risk and schedule evidence to inform commercial planning and delivery assumptions.
Financial case
Examine affordability through annual cost profiles, funding arrangements and Capital & Resource budget provisions.
Management case
Connect delivery schedules, governance, risk and assurance findings to support implementation planning and review.
HM Treasury’s Green Book and Five Case Model provide the appraisal context; the Orange Book sets out principles for risk management. Einro supports analysis and review; it does not replace the full business case, professional judgement or your organisation’s approval process.
Evidence that stays connected
From today’s analysis.
To tomorrow’s decisions.
Capture the reasoning as the work develops. Einro connects assumptions, evidence, analysis and reporting so knowledge stays with the organisation.
Automate the report.
Keep the reasoning.
Create reports from the captured project context, analytical outputs and assurance findings. Bring the evidence together without rebuilding the story in separate documents.
A golden thread
of evidence.
Capture source files, notes and assumptions alongside the inputs they explain. Keep the connection from the original evidence through the analysis to the business-case recommendation.
Knowledge that
outlasts the project.
Retain the decisions, supporting evidence and lessons behind the numbers. Help future teams understand what was known, what was assumed and why a course of action was chosen.
