Assess value for money or cost effectiveness

A decision-focused economic assessment with comparable costs and outcomes, valid arithmetic and explicit uncertainty.

Bring these inputs

Input types: Cost data; Outcome data; Economic framework. Use source documents and evidence you are authorized to share. A missing input is a question or a stop, never permission to invent facts.

Minimum inputs

  • Decision, alternatives, perspective and cost boundaries
  • Currency, price year, costs, outcomes and provenance

Useful if available

  • Relevant discount assumptions, sensitivity ranges and equity evidence
  • Existing economic analysis or framework

Decisions you must make

  • Choose the relevant framework rather than every economic method.
  • Resolve zero/missing denominators and incompatible alternatives before ratios or ranking.

Start in Claude or ChatGPT

Choose how to work, inspect the instructions, then copy them to your own assistant. These controls stay in page memory and reset when you leave. This page does not accept or save your documents, run AI or send these choices.

Task instructions are available in English and Spanish. Each source method keeps its declared language and provenance; methods without an accepted Spanish edition are labeled English and supplied unchanged.

Paste the starter first. It includes intake, the ordered task plan and the exact method for your selected branch, or the default method for your working mode. It asks for the required inputs and decisions before proceeding. Copy each later stage when its required artifacts are ready. Keep the artifacts in your own files; a new chat cannot recover them from this page.

Your chosen assistant processes anything you provide under its own account settings, policies, capabilities and limits. Follow your organization's rules and remove names or sensitive details before sharing material. Check its actual file-reading and output abilities; account access or a copied method does not prove a successful run.

Work through the stages

Each stage names the artifact that the next stage needs. Keep its source references, assumptions, unresolved issues and version label together. Do not continue past a substantive stop or silently treat a draft as accepted.

Stage · vfm-framework

Select the economic framework

Select relevant economy, efficiency, effectiveness and equity questions, CEA or CBA according to the actual decision and evidence.

Bring to this stage

  • source-map
  • input-material

Keep this artifact

  • vfm-framework

Check before moving on

  • State perspective, boundary, currency, year and comparison basis.

If inputs are missing or conflict: List blocking gaps and consequences. Complete only supported parts, label provisional work and do not invent evidence. For unsuitable input explain the fit problem and offer a supported route.

Your decision is required. Resolve conflicting governing sources and consequential assumptions before treating them as agreed.

Methods used: prompt: create-vfm-framework. Full source text, revision and digest are included in the copied instructions.

Stage · vfm-assessment

Apply relevant criteria only. Check comparability, arithmetic, uncertainty and equity.

  • cost-effectiveness-analysis

Record unselected branches as not applicable.

  • Block ratios with zero or missing denominators.
  • Do not rank incompatible alternatives or invent benefits.

Use a branch only when it fits

Optional branch · cost-effectiveness

Analyze cost effectiveness

Use when: Comparable alternatives and outcomes support CEA.

Use actual inputs. Show formulas, units and sources; calculate only supported quantities and meaningful sensitivity.

  • cost-effectiveness-analysis

Check before moving on

  • State whether costs/effects are total, incremental or average.
  • Do not manufacture economic precision from incomplete data.

Revise or resume without losing decisions

Revise after the task review

Each review issue needs a stable ID, artifact/location, source or method basis, consequence and actionable correction. Record accept, reject or amend with a reason and decision/source ID. Preserve the original v1, create v2 and retain unresolved issues. Proposed changes are not accepted decisions. Rerun the affected source-method checks and cross-artifact checks; preserve both changed and unchanged commitments.

Use this combined copy after the task review. To revise an earlier artifact, choose Revise with decisions and copy its own stage instructions above. Bring the original, applicable review and issue dispositions. Later artifacts that do not exist remain unperformed.

Bring back

  • source-map
  • named-draft-to-revise
  • corresponding-issue-register
  • issue-dispositions

Already-produced context, when available

  • vfm-framework
  • cost-effectiveness-analysis

Bring only context that was actually produced and branch artifacts from selected branches. Retain their names and versions during revision.

Version names for supplied revision targets

These are naming choices, not a requirement to create every artifact. Revise only the named draft you supplied.

  • vfm-framework to vfm-framework-v2
  • review-issues to review-issues-v2
  • cost-effectiveness-analysis to cost-effectiveness-analysis-v2

Preserve

  • Original supplied sources and every original named draft
  • Stable question, indicator, finding and issue IDs

Bring the latest named artifact, source inputs, issue list, decision dispositions and the method text for the next stage. State what passed, failed or remains unperformed. The assistant must inspect those materials and confirm the next step before continuing.

Finish with a usable output

  • Return usable named deliverables, source/decision notes, limitations, unresolved issues and the change record. Check repeated IDs, definitions, periods, denominators, citations and arithmetic across artifacts. A documented unsuitable-input decision or an unexecuted specification can be the honest usable outcome.
  • Distinguish unperformed, blocked, proposed and checked work. Never claim fieldwork, computation, pilot completion, approval, causal identification, file generation or host capability without actual evidence.
  • Use the review and dispositions to produce the final revised set. Retain unresolved decisions and proposed commitments visibly.

Keep the source inputs, named artifacts, checks, decisions and final version together. A draft, an accepted decision, a checked calculation and a created file are separate facts. Mark any unperformed check clearly.

A fictional transition

Fictional case: one option reports cost per participant and another cost per household in different years. Return comparability requirements before ranking.

This small illustration is fictional. It is not an observed assistant result or real project evidence.

Source resources and optional assets

The task connects existing methods and keeps their criteria. Copied stage instructions contain the resolved method text and its source identity. Adaptations are labeled separately. Resources are in English unless a resource explicitly says otherwise. Earlier install packages may contain different bytes from the current portable methods. Source projection, installation, host checks and publication are separate facts.
