A signal earns attention. Evidence earns action.
A market change may justify investigation. It does not, by itself, establish need, budget, authority, timing, access or a commercially viable response.
Important qualification: the method does not remove uncertainty. It makes uncertainty, trade-offs and the reason for allocating scarce resources visible.
Businesses are receiving more signals than they can responsibly pursue.
Supply-chain disruption, policy change, artificial-intelligence adoption, climate exposure and uneven investment conditions can all create legitimate commercial questions. They can also create false urgency.
In October 2026, the Office for National Statistics reported that 48% of businesses with 10 or more employees were concerned about at least one supply-chain factor over the coming year. Thirty per cent of businesses reported using at least one artificial-intelligence technology, rising to 51% among businesses with 250 or more employees.1 These are material changes in the operating environment. They are not evidence that a named organisation has an approved requirement, reachable decision-maker or purchasing timetable.
The Bank of England’s September Agents’ Summary described investment intentions as uneven and only slightly positive from a low base. Demand uncertainty, cost inflation and borrowing costs continued to constrain decisions, while essential investment, energy pressures and technology spending created movement in selected areas.2 The commercial implication is not “the market is buying”. It is that conditions differ by organisation, purpose and timing and need investigation at that level.
This distinction matters equally inside a business. A competitor announcement, new regulation or engagement spike can trigger executive attention. Unless someone establishes the affected position, material consequence and available choices, the organisation risks moving from news to action without passing through a decision.
A change, a signal and a decision are different things.
Something happened.
A policy was published, funding announced, a leadership appointment made, a contract notice issued or a performance condition changed. The event has a source and an effective date.
The event may matter to a defined commercial question.
A signal is not inherent in the event. Relevance depends on the organisation, offer, location, delivery capacity and decision being considered.
A reasoned explanation of what the signal could mean.
Interpretation must remain separate from the verified fact and must expose plausible alternatives.
An accountable choice about resource.
Monitor, investigate, test, act or close, with an owner, reason, boundary and review point.
A useful record also distinguishes four dates: when the underlying event occurred; when evidence was published; when the organisation detected it; and when a decision could realistically be taken. Collapsing those dates can make old evidence look new or immediate access look available when it is not.
Good decisions start with a clearly framed question.
Define the objective, case for change and alternatives.
The 2026 Green Book requires appraisal to begin with rationale, objectives and a proportionate comparison of options, including business as usual. Frontier applies this as a transferable discipline: an external signal should be tested against a defined objective before it attracts resource.3
Limit: the Green Book is public-sector guidance. It is not presented here as a private-sector legal requirement.Agree the context, boundaries, assumptions and uncertainty.
The AQuA Book says analysis should start with a shared understanding of the problem and its context. It also requires work to be fit for purpose, proportionate, documented and clear about limitations.4
Commercial translation: a senior sponsor should know what decision the work serves before a team starts collecting evidence.Unexamined uncertainty becomes hidden fragility.
The National Audit Office found that plans which do not examine wider uncertainty can create false confidence and weaker resilience. Its response is not to wait for certainty, but to identify, analyse and plan for material uncertainty.5
Limit: the guide draws from public programmes; the principle must be adapted to business scale and consequence.Buying intent cannot be inferred from a signal alone.
A signal may establish that a condition changed. Buying intent requires additional evidence about need, authority, budget, access, timing and an acceptable route. Engagement can strengthen a reason to investigate; it does not close those gaps.
What would change the conclusion: direct, attributable evidence of an authorised requirement and route can materially strengthen the decision state.The Signal-to-Decision Test.
Seven tests turn a broad market development into a proportionate, owned response.
- 01Observed change
What actually happened? Preserve the primary source and relevant dates.
- 02Affected position
Which organisation, site, function, buyer or market is affected?
- 03Commercial relevance
What could change in cost, demand, capacity, risk or performance?
- 04Materiality
Is the possible effect large enough to deserve management attention?
- 05Timing and conditions
Why now? What must happen next? What could prevent movement?
- 06Available choices
Continue, do the minimum, act differently or obtain further evidence.
- 07Proportionate response
Monitor, investigate, test or act, with an owner and review point.
A funding announcement becomes useful only after the missing conditions are tested.
A public body announces a capital programme relevant to a supplier’s offer.
The announcement is real and relevant to the broad market. It does not name the supplier’s target organisations, show their local condition, confirm project eligibility or create an accessible route.
Fact and commercial inference are collapsed. The team starts broad outreach.
Some organisations have a relevant problem; others have already committed, lack readiness or sit outside the route.
Resource follows evidence and access. Reasons are retained for review.
The value is not a larger lead list. It is a smaller, explainable decision set and an explicit account of what would need to change before the other organisations deserve attention.
What changes when signals are treated as questions.
The sponsor sees what is known, why it matters and which choice is requested.
Routine changes receive proportionate treatment; irreversible choices receive more assurance.
Teams avoid confusing market coverage with reachable demand.
Contradictory evidence, route barriers and missing authority remain part of the record.
For an SME
The method protects a small number of people from spreading attention across every visible change. It supports a practical choice: one investigation now, a defined watchlist and clear exclusions.
For a national or multi-site organisation
The method creates consistency without pretending every region, business unit or site is the same. Common tests make local variation comparable, while decision authority stays with the appropriate owner.
What to do with the next signal.
- What changed and what is the primary dated source?
- Which organisation, market, site or decision is actually affected?
- What consequence for cost, demand, capacity, risk or performance is plausible?
- What evidence would disprove that interpretation?
- What material facts are still unknown?
- Which alternatives, including doing nothing or waiting, must be compared?
- Does this justify monitoring, investigation, testing or action?
- Who owns the next decision, and when will it be reviewed?
when the event is real but has no material connection to the defined decision.
when relevance is plausible but a future trigger, funding route, authority or timing condition is missing.
when the possible consequence is material and obtaining the missing evidence is proportionate.
when the evidence, route, timing, authority and downside are sufficient for the specific decision, not when uncertainty has disappeared.
Qualification is not certainty.
Early markets sometimes require exploration before evidence becomes strong. A reversible, low-cost test may be sensible where a large irreversible commitment is not. The standard is proportionality: enough evidence and control for the consequence of the next step.
This paper does not supply universal scoring weights. Materiality, risk tolerance, decision rights and the cost of delay vary by organisation. Any scoring model must preserve the underlying reasoning and allow a person to challenge the result.
What would change the conclusion? Direct evidence of an authorised need, funding, decision timetable and accessible route can move a record from investigation to action. Evidence of prior commitment, poor fit or unavailable capacity can close it just as decisively.
