This article sets out an augmented decision method in which AI prepares analyses and scenarios while the company retains control of its data, checks and final judgement.

  • Audience: SME and mid-cap leaders, data managers, and finance or operations teams.
  • Scope: decisions that can be quantified from internal data, illustrated through pricing, margin and volume questions.
  • Thesis: compute has become much cheaper, while data preparation and verification remain substantial investments.

By Paul-Antoine TUAL, AI Transformation Leader, Croissance et Transitions. August 2026, revised September 2026.


1. A better-informed leadership decision

A 4% price rise, the closure of a product line or the recruitment of a salesperson can now be examined faster when the required data is accessible and its definitions are stable.

  • Hypothesis: state the decision, horizon and evidence that would make you abandon it.
  • Data: assemble volumes, margins, discounts, logistics costs, attrition and operational capacity.
  • Output: compare several scenarios instead of requesting one recommendation.

A properly connected agent can prepare the dossier in minutes or hours, although speed says nothing by itself about the quality of the data, allocation rules or conclusions.

  • It retrieves three years of sales from the ERP and CRM under least-privilege access.
  • It recalculates margin after a documented allocation of logistics costs.
  • It exposes seasonality, assumptions and sensitivities for every scenario.

IBM’s global 2026 survey shows that leaders are open to AI-generated input, while measuring a stated attitude rather than decision quality or the maturity of French SMEs [9].

  • Sample: 2,000 CEOs and equivalent senior leaders across 33 geographies and 21 sectors.
  • Finding: 64% say they are comfortable making a major strategic decision from AI-generated input.
  • Cautious reading: analysis complements experience; it transfers neither judgement nor accountability to the model.

2. Separate compute, access and production

Comparing an agent task with a complete data project creates a false equivalence because the two purchases cover different assets, risks and time horizons.

  • Data project: pipelines, reference data, data model, security and recurring operations [1].
  • One-off analysis: collection, business framing, interpretation and presentation [3].
  • Agent task: computation and synthesis inside an environment that has already been prepared.

Official pages checked on 6 September 2026 confirm low access and execution costs, while making clear that prices vary with licences, region, volume and tools invoked [5][6][7].

  • Microsoft lists Microsoft 365 Copilot at €28.10 excluding VAT per user per month on annual billing, alongside a qualifying licence [5].
  • Anthropic lists Claude Pro at $20 per month, or $17 per month on annual billing, subject to usage limits [6].
  • Google estimates a standard Deep Research task at $1–$3 under preview pricing and says cost depends on research depth [7].
Building a decision case on your data: yesterday's three routes, the agentic route of 2026 Indicative comparison of different scopes: a data project, an in-house analyst, an outsourced study and a connected agent task; the agent price excludes the data foundation, access and verification work. Building a decision case on your data: yesterday and in 2026 Yesterday: three billed routes Data / BI project €10,000 to €30,000 for an SME foundation 3 to 6 weeks, then €300 to €5,000/month In-house data analyst around €45,000 gross per year (median) recruitment: several months Outsourced study €8,000 to €12,000 per study several weeks of lead time In 2026: the agentic route Agentic AI connected to the data access: €17 to €28.10/month per user single analysis task: $1 to $3 scenarios returned in minutes or hours still needed: fit data + verification Ranges documented in sources [1] to [8]; prices read on 18 August 2026 on the vendors' official pages. Indicative comparison: scope and upstream costs differ.
Figure 1. Indicative orders of magnitude for different scopes: an agent task can be inexpensive once data and access already exist; a data project funds that foundation. Vendor prices checked 6 September 2026 [1]–[7].

The agentic advantage lies in a controlled sequence of operations, while MCP provides an open protocol for exposing tools and context sources to AI applications [6].

  • An agent can read a file, run a query, apply a business rule and produce a traceable dossier.
  • The connector should restrict authorised resources, operations and identities.
  • Token budgets, tool calls and error recovery remain measurable costs.
  • Marginal cost falls most when the company has already funded its data, access and controls.

3. Turn intuition into testable assumptions

A useful decision dossier makes assumptions contestable and links every scenario to observable data without presenting the model’s projection as a certain forecast.

  • Base: a central scenario calculated from validated data and a relevant period.
  • Variants: high and low assumptions for variables that genuinely drive the result.
  • Refutation: thresholds that invalidate the preferred scenario and a premortem of failure causes [27].
  • Decision: reversal cost, signals to monitor and a review date.

Field experience remains valuable for asking the right question, and an explicit procedure can then reduce anchoring, confirmation, status quo and overconfidence biases documented by decision psychology [26].

  • Write down the intuition before seeing results to avoid rewriting the hypothesis afterwards.
  • Ask for evidence against the preferred scenario to counter confirmation bias.
  • Vary visible assumptions to expose the influence of the first number proposed.
  • Record the choice and actual outcome to calibrate intuition over time.

Bpifrance Le Lab’s 2026 barometer illustrates the gap between adoption and reported gains among French mid-caps, without allowing that gap to be attributed to any particular method [10].

  • 77% of respondents report professional generative AI use by themselves or their staff.
  • Among AI-using mid-caps, 17% report time savings, equivalent to 13% of the full sample.
  • The result supports measuring each use case against a defined indicator rather than inferring broad productivity from adoption.

4. Verify in proportion to the stakes

BIRD and Spider 2.0 show that performance varies sharply with the task and protocol, which supports local testing without turning a benchmark score into a business error probability [11][12].

  • BIRD publishes a 92.96% human reference and an 81.95% historical best on its execution evaluation [11].
  • Spider 2.0 covers enterprise tasks of different complexity and warns that scores may move as evaluation issues are corrected [12].
  • Tracks, data and settings differ; Figure 2 shows dated laboratory results rather than a universal ranking.
  • A 2026 study also identifies annotation errors in text-to-SQL reference sets [13].
Measured accuracy of data-analysis agents by task type Horizontal bars: 96.7% success on Spider 2.0's targeted Snowflake queries, 92.96% for the human reference of the BIRD benchmark, 81.95% for the best agent on BIRD, 76.23% on Spider 2.0 Lite, 65.6% on the full analytics workflows of Spider 2.0 DBT. What an agent actually gets right (accuracy, leaderboards of 18 August 2026) Spider 2.0 Snow (targeted queries) 96.7% Human reference (BIRD) 92.96% Best agent (BIRD) 81.95% Spider 2.0 Lite 76.23% Spider 2.0 DBT (full workflows) 65.6% 0 50% 100% Dated results on different tracks and protocols; they do not predict your error rate.
Figure 2. Published results from several BIRD and Spider 2.0 tracks whose data, settings and metrics differ; the comparison illustrates protocol sensitivity and does not predict production reliability [11][12].

Long-running research evaluations likewise support criterion-by-criterion review because a fluent answer can omit requirements or propagate an error between stages [14][15].

  • Check coverage, accuracy, freshness and source diversity separately.
  • Bind decisive calculations to a system of record rather than a secondary citation.
  • Ask the accountable business owner to review assumptions and exceptions.

A robust control combines technical traceability, arithmetic verification and business reconciliation, with effort scaled to the potential cost of an error.

  • Retain the query, data version, filters and transformations.
  • Recalculate a representative sample and every sensitive total by hand.
  • Reconcile revenue, margin and receivables with the relevant accounting systems.
  • Review unexplained discrepancies before presenting the dossier to the executive committee.

5. Prepare governed, usable data

Vendor-sponsored surveys published in 2026 frequently flag silos and data quality, although their large-organisation samples do not automatically describe a French SME [16][17].

  • Cloudera/HBR Analytic Services reports 7% of respondents calling their data “completely ready” and 56% citing silos [16].
  • Nasuni/Sapio reports that 46% saw their initiatives reveal quality or governance problems [17].
  • These findings are risk signals; a local assessment should measure the company’s actual data, permissions and uses.

A reusable agent-ready foundation combines quality, access, security and history so that later analyses can reuse governed assets.

  • Reference data: one stable identifier for each customer, product, supplier and legal entity.
  • Access: monitored APIs or connectors, least-privilege scopes and separate service identities.
  • Confidentiality: classification of margins, salaries and cash data before any external processing.
  • Memory: retained assumptions, decisions, outcomes and corrections for the next cycle.
  • Control: apply the agentic-system rules and sovereignty framework to the actual use case.

6. Avoid generic recommendations

A 2026 exploratory study of seven models and seven strategic tensions finds frequent convergence towards socially valued options, a useful design signal that remains insufficient to predict every recommendation produced in business [19].

  • The protocol covers 15,000 simulations and reports convergence on six of seven tensions.
  • The effect depends on the models, dilemmas and simulated contexts studied.
  • A generic recommendation should therefore be tested against the company’s own constraints and data.

Private data can make analysis more specific when it is relevant, clean and correctly interpreted, without becoming an automatic defence against copying or error.

  • Ten years of customer history may reveal cohorts and cycles absent from public data.
  • Actual margins and segment conversion rates provide company-specific constraints.
  • Metric definitions, controls and feedback speed complete that asset, as discussed in the end of the model race.

For buyers, the practical consequence is to purchase a better-informed decision rather than a volume of pages, requiring traceability, explanation and the ability to challenge the first answer.

  • The deliverable should connect every decisive claim to verifiable data or a source.
  • The supplier should state assumptions, limits and human controls.
  • Value should be judged on decision quality and observed outcomes, rather than analysis volume.

7. A five-step leadership protocol

The protocol consists of five successive steps that produce a comparable, auditable and reversible dossier before the final decision.

  • Write the decision and its turning-back criterion. One sentence: “Should we do X before Y, given Z”. Then the reversibility criterion: what would make us say no, and how much turning back costs. Your intuition sets the hypothesis; that is its place, and decision-gated development makes it the first guardrail.
  • Connect the agent to the systems. A connector with minimal access rights to the ERP, the CRM or the warehouse, rather than three-week-old manual exports that freeze figures already wrong.
  • Require scenarios, their assumptions and their refutation. Three quantified trajectories, written assumptions, sensitivity analysis, and the premortem of the preferred scenario: what kills it, with what probability, detectable through which signal.
  • Control before believing. The rules of section 4: queries and sources required, a second independent engine, a hand-recounted sample, accounting reconciliation. Any unexplained gap is an alert, not a detail.
  • Decide in session, with a cool head. Group the trade-offs into a dedicated decision session, as we detail in the personal effectiveness method, and keep the human signature on everything that commits the company.

IBM’s survey describes an expectation of greater automation for codifiable operational decisions, reinforcing the need to define eligible decisions, exceptions and accountable owners in advance [9].

  • Respondents expect 48% of operational decisions where consistency and guardrails can be codified to be made without human intervention in 2030, up from 25% at the time of the survey.
  • This is a respondent forecast; it guarantees neither adoption speed nor decision quality.
  • Figure 3 therefore places analysis in a loop where humans frame, verify, decide and measure.
The circuit of the instructed decision: where the cost goes, where the human remains Five steps as boxes linked by arrows: frame (intuition sets the hypothesis, cost in leader's time), analyse 360 degrees with scenarios (agents, a few euros), verify (counter-engine and manual sample, the new cost), decide (leader, in session), execute and measure; a return loop shows that each cycle enriches the company's own data. The instructed decision: where the cost goes, where the human remains 1. Frame intuition sets the hypothesis and the turning-back test cost: your time 2. Analyse 360° data, quantified scenarios (agents) cost: a few euros 3. Verify counter-engine, manual sample, reconciliation the new cost 4. Decide in session, with a cool head (the leader) your signature 5. Execute and measure the gaps data enriched each cycle enriches your own data and lowers the cost of the next decision
Figure 3. The informed-decision loop: analysis accelerates at step 2, verification remains explicit at step 3, the human retains sign-off at step 4, and observed outcomes enrich the next cycle.

The full cost has shifted

AI reduces the cost of generating an analysis, while decision value still depends on data quality, calculation checks and accountable judgement.

  • Cheaper: variants, exploratory queries, synthesis and presentation.
  • Still costly: integration, security, reference data, business validation and supervision.
  • Still human: defining the stakes, accepting risk and making decisions that commit the company.

A first experiment can use one real, reversible decision and compare it with the usual process against criteria defined before the test.

  • Choose a dossier for the next executive meeting and freeze the starting data.
  • Compare elapsed time, full cost, calculation discrepancies, assumption quality and usefulness.
  • Decide whether to industrialise, repair the data foundation or stop the use case.

The Junyr AI maturity audit is a free, no-commitment 30-minute video call that positions the company on the scale, identifies its main blocker and first sensible project, and provides a one-page follow-up.

Frequently asked questions

What can an agentic AI connected to my company's data actually analyse?

An agent can combine the data it is authorised to reach and prepare a decision dossier, provided that business definitions, permissions and checks are explicit.

  • Sources: ERP, CRM, data warehouse or approved files with a known freshness date.
  • Analyses: sales, margins, stock, lead times, seasonality and quantified scenarios.
  • Limits: missing data, inconsistent identifiers, implicit business rules and excessive access.
How much does an AI data analysis cost in 2026?

The compute for one analysis may cost only a few euros, while the full cost depends mainly on data preparation, integration, security and review time.

  • Execution: Google estimates a standard Deep Research task at $1–$3 under preview pricing [7].
  • Access: per-user subscriptions and qualifying licences sit on top of compute.
  • Production: connectors, data quality, logging, testing and supervision often dominate the budget.
Does AI analysis replace the business leader's intuition?

Intuition supplies a useful hypothesis, while agentic analysis can test it against observable facts before the leader takes responsibility for the choice.

  • Write the hypothesis and the evidence that would make you abandon it.
  • Request several scenarios with visible assumptions and sensitivities.
  • Keep human approval for choices affecting capital, employment, legal exposure or reputation.
Can the figures produced by an AI agent be trusted?

Figures become decision-grade when their provenance, calculation and reconciliation against a system of record can be reproduced.

  • Require the queries, filters, periods and sources behind every result.
  • Recount a sample and reconcile totals with the systems of record.
  • Treat BIRD and Spider 2.0 as capability benchmarks, never as a predicted error rate for your environment.
Does an AI agent replace a data analyst or a BI project?

An agent automates part of extraction and explanation, while analysts and data teams remain responsible for meaning, quality and the control framework.

  • The agent accelerates exploratory queries, reconciliations and scenario variants.
  • The analyst defines metrics, resolves anomalies and validates interpretations.
  • BI remains useful for recurring, governed and shared indicators.
My competitors use the same AIs: where is the advantage?

The advantage depends less on the chosen model than on private data quality, business rules and the learning speed of your decision loop.

  • Proprietary history: actual margins, causes of loss, seasonality and exceptions.
  • Proprietary process: metric definitions, controls and feedback from observed outcomes.
  • Proprietary discipline: recorded decisions, revised assumptions and errors converted into data.
Can AI take the decision for me?

AI can execute bounded operational decisions, but the organisation must assign clear accountability for choices that materially commit the business.

  • Automate only explicit rules with thresholds, logging and a stop mechanism.
  • Escalate exceptions, conflicting data and cases outside policy.
  • Keep human approval for significant effects on people, finance, law or reputation.
