Fictional default example · 2025.
What the selected record shows. Supply minus demand: -300 kg. Review quantity/capacity gap.
Next step. Review quantity/capacity gap. Prepare matching review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A quantity match does not establish quality, delivery feasibility or a contract.
Compare the same specification and unit, uncommitted quantity and overlapping delivery windows. Keep mandatory quality and use conditions explicit.
A candidate match does not reserve stock, appoint a person, authorize waste reuse or form a contract.
Other required records: Product; grade; available quantity; commitments; harvest window; buyer requirements.
Calculation appendix
Compare procurement cost per retained kilogram for equivalent grades.
What the selected record shows. (180 + 20) / 0.950 = 210.53 LKR per retained kg.
Next step. Compare the stated price result and payment terms. Prepare quote comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Loss and transfer-cost assumptions must match; this is not a confirmed purchase price.
Landed cost per retained kg = (purchase price per initial kg + matching transfer/handling cost per initial kg) / (1 − assumed mass loss% / 100), only when some mass is retained.
Quotes, loss assumptions and costs are fictional. Compare matching grades, weighing bases, payment timing and terms. The result does not authorize a purchase, sale, financing or supply agreement.
Other required records: Product; grade; offer price; unit; market; date; delivery cost.
Compare purchase and sale quotations after stated costs and mass loss.
What the selected record shows. Quoted net return per purchased kg: 10.9 LKR/kg.
Next step. Check matching product grades, quantities, losses and quote periods. Prepare quote comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A spread does not establish actual profit or excess market power.
Quoted spread = sell−buy. Net scenario return per purchased kg = sell×(1−loss%/100)−buy−matching transfer costs.
Use matching grade, price date, currency, mass basis and payment terms. This quotation scenario excludes unlisted costs and is not realized profit or a forecast.
Other required records: Comparable purchase price; sale price; transport; handling; losses; period.
Check buyer-order tasks against deadlines, resources and dependencies.
What the selected record shows. Planned duration: 3 days. Resolve overlapping resource bookings.
Next step. Resolve overlapping resource bookings. Prepare schedule review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
The example does not accept an order or guarantee delivery.
Check start/end order, operating window, effort, predecessor completion and overlapping bookings for the same resource. A conflict is flagged; no optimal schedule is invented.
Other required records: Order; delivery window; available supply; transport capacity; contractual conditions.
Compare delivered and agreed quantities for the same accepted order.
What the selected record shows. Difference: -10 kg.
Next step. Check the matching records and reasons for the difference. Prepare difference review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A shortfall needs acceptance and source checks before determining liability.
Observed value minus Planned value. Relative change = 100 × difference / Planned value when the earlier value is positive.
Other required records: Supplier; promised quantity; delivered quantity; promised date; actual date; quality.
Check received-lot observations against matching specifications and methods.
What the selected record shows. The supplied Fictional received-lot moisture, wet-basis mass percent result is 13.5 %. Its stated comparison range is 0 to 12 %. Outside example comparison bounds.
Next step. Obtain the missing evidence listed below. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
An example bound does not certify or reject a whole shipment.
Compare the measured value only with matching parameter, unit, use and averaging period. Retain limit source/version and censored-result status.
Example bounds establish no compliance or diagnosis. Ambient, drinking-water, effluent, crop, food, air and noise standards are not interchangeable. A censored result is not an exact zero. Wet-basis mass percentages must be between 0 and 100; the buyer or laboratory specification still needs confirmation.
Other required records: Lot; product; test results; buyer specification; sampling method; rejection evidence.
Check usable perishable stock against commitments and expected receipts.
What the selected record shows. Uncommitted usable stock: 310 kg. Review replenishment gap.
Next step. Review replenishment gap. Prepare stock review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Quantity does not establish freshness, saleability or certain replenishment.
Usable = physical−quarantined−expired (non-overlapping groups). Available = usable−commitments. Additional gap = max(0, new demand−available).
Stock must be compatible by item, lot, condition, expiry and delivery window. Do not allocate quarantined/expired stock or silently erase overcommitment.
Other required records: Usable stock; commitments; expected demand; lead time; shelf life; expiry.
Reconcile input mass with saleable output, stock, transfers and by-products.
What the selected record shows. Unaccounted physical share: 6.667 %.
Next step. Reconcile the input, output, stock and transfer records. Prepare loss-balance review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
An unaccounted balance does not identify the stage or cause of loss.
Unaccounted = input − saleable output − usable by-products − closing stock − transfers out. Share =100 × unaccounted / input.
Use a consistent moisture basis and process boundary. Unaccounted mass is not automatically avoidable food loss or spoilage.
Other required records: Lot input; saleable output; spoilage; transfers; moisture; stage.
Compare supplied collection journeys and access constraints.
What the selected record shows. The supplied journey is 24 km and 65 minutes. Usable capacity is 18 against 15 required in the stated service units. Access and operating conditions: Unresolved.
The prototype calculates no route or guaranteed travel time.
Compare supplied route times/distances, usable capacity and documented access/window constraints. Display feasible candidates; no route optimization is implied.
Straight-line distance is not a road route. Example routes establish no current road status, emergency clearance or safe evacuation instruction. This decision view compares supplied journeys. It does not calculate a route or run a coordinate-based analysis.
Other required records: Origins; buyers; road network; vehicle capacity; delivery windows; costs.
Compare immediate sale and storage choices under explicit price and quality assumptions.
What the selected record shows. There is not enough information to choose this option. Obtain the records and evidence about conditions listed below. The supplied budget less cost is 300,000 LKR.
Next step. Obtain the missing records before choosing. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A budget balance does not establish future prices or safe storage.
Compare each alternative's stated benefit, adverse effects, domain evidence and mandatory constraints. Where cost and budget are supplied, budget balance = budget − option cost. A budget balance alone does not determine domain feasibility or select an option.
Other required records: Storage costs; shelf life; losses; current price; future-price scenarios; cash need.
Review chronological purchase and sale cash events for temporary shortfalls.
What the selected record shows. Lowest projected cash: -200000.00 LKR; shortfall: 200000.00 LKR; closing cash: 180000.00 LKR. The chronological events explain the difference.
Next step. Review funding and payment timing before committing. Prepare balance review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Positive closing cash does not rule out an earlier financing gap.
Order the supplied dated receipts and payments. Start with the stated opening cash; add each receipt and subtract each payment once. Minimum cash is the lowest chronological balance, including opening cash. Shortfall = max(0, −minimum cash). Closing cash is opening + receipts − payments.
These are dated fictional cash assumptions, not actual bank balances or a credit recommendation. A positive closing balance can conceal an earlier shortage. Same-day receipt/payment ordering needs evidence.
Other required records: Opening cash; purchase payments; customer receipts; transport; debt; dates.
Identify customer-payment cases past their recorded response date.
What the selected record shows. Open days past due: 29 days. Follow up overdue case.
Next step. Follow up overdue case; confirm the missing condition evidence. Prepare evidence request in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A deadline does not establish the legal debt or authorise collection action.
Open age = assessment date − received date. Days past due = max(0, assessment date − recorded due date) for open cases. Show documented critical conditions separately.
Example due dates are not legal service standards. Do not alter statutory deadlines by silently subtracting pauses, or infer severity from age alone.
Other required records: Invoice; due date; amount; receipts; dispute; payment terms.
Review the stated sales exposure across buyers.
Verified published component · HHI concentration component
What the selected record shows. Category amount: 900,000 LKR.
Next step. Review the complete portfolio, category definitions and exposure constraints. Prepare concentration review in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Concentration does not establish buyer default probability or a complete portfolio.
Category share = 100 × category amount / total compatible category amounts. HHI = sum of squared fractional shares, displayed on a 0–1 scale.
Categories must be mutually exclusive and cover the stated frame. Do not mix values, quantities, plots or hectares, or treat an HHI competition threshold as an institutional policy. This is a fictional selected sales portfolio, not an actual trader or market total. No concentration-policy threshold is inferred.
Other required records: Buyer sales; total sales; payment history; product; period; concentration.
United States Department of Justice · Herfindahl Hirschman IndexGovernment publication · Definition and four-firm worked example
The screen uses fractional shares on a 0–1 scale, equivalent to the published percentage-share score divided by 10000. Local exposure categories and policy thresholds are not verified by this source.
Review the stated procurement quantities across suppliers.
What the selected record shows. Category amount: 95 kg.
Concentration does not establish supplier reliability or an available substitute.
Categories must be mutually exclusive and cover the stated frame. Do not mix values, quantities, plots or hectares, or treat an HHI competition threshold as an institutional policy.
Other required records: Supplier volumes; product; total supply; alternatives; risk; delivery reliability.
Review variation in comparable procurement-price observations.
Verified published formula · Sample coefficient of variation
What the selected record shows. Observed value: 104 LKR/kg.
Next step. Check the comparable series and the reason for its variation. Prepare variation report in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A short series does not forecast prices or establish a safe procurement position.
Display observations in dated order. Sample SD uses n−1; coefficient of variation = 100 × SD / positive mean.
Match definitions, methods, grade, location and reference basis. Gaps are not joined. Descriptive variation is not a forecast, causal effect or significant trend.
Other required records: Comparable price series; dates; product grade; market; sample coverage.
National Institute of Standards and Technology United States · Dataplot Coefficient of VariationGovernment publication · Description, sample coefficient of variation and ratio-scale restrictions
Use a meaningful zero and positive mean. Local series selection and decision limits still need confirmation.
Trace missing source links for the stated traded lots.
What the selected record shows. Broken or affected lineage: 1 items. Investigate linked downstream lot.
Next step. Investigate linked downstream lot. Prepare source comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A reference chain does not prove physical identity or product conformity.
Follow recorded upstream→downstream links within the same scope and period. Flag missing links; a confirmed defect identifies downstream linked candidates for authorized investigation.
Recorded lineage is not proof of product identity or recall authority. Preserve multi-source batches, transfers and versions; do not clear unlinked lots as safe.
Other required records: Farm source; lot ID; transfers; storage; buyer shipment; certification.
Compare candidate markets using buyer, product and logistics evidence.
Cost alone does not establish demand or a feasible sale.
Other required records: Market demand; access; competition evidence; transport; margins; regulatory needs.
Find missing records before a supply-agreement referral.
What the selected record shows. The required evidence is incomplete for this contract readiness case. The items below identify what must be obtained or reconciled.
The prototype does not authenticate a counterparty or create a contract.
Check each required item and retain its reference. A documented item is not a scientific, legal or institutional approval.
Evidence completeness alone cannot establish suitability, eligibility, safety, permission or method validity.
Other required records: Offer; quantity; grade; delivery; payment terms; authority; documented conditions.
Compare packaging choices using loss evidence, costs and buyer requirements.
Descriptive benefits do not establish measured loss reduction or packaging conformity.
Other required records: Packaging costs; damage rates; capacity; buyer specification; handling conditions.
Find missing product-grade and unit definitions before joining records.
What the selected record shows. The required evidence is incomplete for this product catalogue case. The items below identify what must be obtained or reconciled.
Matching labels do not establish equivalent grades or mass conventions.
Other required records: Source product; grade definition; unit; conversion evidence; reference catalogue.
Source. International publication.
Data needed. Rice type, lot, representative moisture result, buyer specification and destination requirements.
Method. For rice covered by CXS 198, compare mass-percent moisture with the applicable limit. Codex gives 15% as the general maximum and allows lower limits for specified destinations or conditions.
Worked example. A milled rice lot tests at 14.4%. Compare it with the applicable buyer or destination specification before accepting it. A 15% example limit would pass the moisture check.
Next step. Hold the affected lot for retest or seek the buyer’s quality determination before acceptance.
Codex Alimentarius Commission, Standard for Rice. CXS 198-1995, §§1 and 3.2.1, product scope and moisture content.
Confirm scope, sampling method and the stricter local, buyer or destination requirement that applies.
