Define the case
Establish the opportunity, geography, sponsor, intended outcome and decision.
Decision infrastructure
Turn a promising idea into an evidence-governed decision.
TAY assessments make the reasoning visible: what is known, what remains uncertain, which constraints matter, and what must happen before capital or implementation decisions are justified.
From evidence to action, with uncertainty visible.
Test the evidence
Separate verified facts, source claims, assumptions and unresolved gaps.
Understand the market
Assess demand, beneficiaries, delivery context and material constraints.
Assess feasibility
Examine technical, institutional, regulatory, commercial, environmental and social conditions.
Structure the pathway
Connect constraints to mitigations, responsible actors, capital options and sequencing.
Decide and learn
Record decision conditions, watchpoints, accountability and outcomes for future learning.
Confidence must be earned.
Assessment conclusions should be traceable to evidence and distinguish source-stated facts from analytical interpretation. Missing evidence is recorded as a gap—not silently converted into a positive finding.
