Compare estate production costs per matching crop-output unit.
Validation required
Fictional default example · 2025.
What the selected record shows. The supplied costs total 497,000 LKR for 4,500 kg green leaf. Cost per matching unit is 110.444 LKR/kg green leaf.
Next step. Review cost components and comparable verified outputs. Prepare cost comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Unit cost does not establish quality, efficiency causes or an appropriate cost reduction.
Sum non-overlapping costs, then divide by the matching verified quantity for the same currency and accounting period.
An absent or zero denominator has no unit-cost result. Keep fixed, variable and opportunity costs identifiable. The denominator is green leaf, not made tea. Compare the same moisture, weighing, cost and accounting-period basis.
Other required records: Crop; saleable output; labour; inputs; energy; hectares; accounting period.
Calculation appendix
Compare soil and water outcomes in the supplied observation groups and periods.
Verified published formula · Difference-in-differences arithmetic
What the selected record shows. Treatment change: 17; comparison change: 7; difference in changes: 10 mm/season. This comparison alone does not establish causation or benefit.
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.
A difference in changes does not establish a management-practice effect.
(Treatment after−before) − (comparison after−before), using the same outcome definition and periods.
The arithmetic alone does not establish causation. Design, parallel trends, confounding, attrition, uncertainty and adverse effects need appropriate evidence.
Other required records: Practice; baseline condition; follow-up; comparison blocks; rainfall; uncertainty.
World Bank · Impact Evaluation in Practice Second EditionInstitution publication · Chapter 7, table 7.2, printed page 140, PDF page 170
The formula is verified. Causal interpretation still requires a defensible study design, comparison and assumptions.
Compare rehabilitation and replanting choices using block and resource evidence.
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.
Cost alone does not establish plant health, productivity or the best intervention.
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: Block age; yield; plant condition; area; replant cost; income gap.
Find workers without confirmed access to the agreed support.
What the selected record shows. 30 workers are known to be uncovered; 5 have unknown coverage. 65% are confirmed covered.
Next step. Check the records behind the uncovered and unknown groups. Prepare coverage follow-up in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Coverage does not establish service quality, eligibility or worker benefit.
100 × distinct covered eligible units / eligible frame. Known uncovered = frame − covered − unknown.
Count each eligible unit once for the selected service and period. Received messages, attendance, adoption and outcomes are separate measures.
Other required records: Eligible workers; consented needs; services received; estate; period.
Find missing site, soil, climate and cultivar evidence before an estate-crop referral.
What the selected record shows. The required evidence is incomplete for this crop suitability case. The items below identify what must be obtained or reconciled.
The checklist does not select a suitable crop or cultivar.
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: Soil; elevation; rainfall; temperature; shade; cultivar requirements; restrictions.
Separate confirmed plant survival, failure and unknown follow-up.
What the selected record shows. Confirmed survival lower bound: 78 %.
Next step. Check unknown follow-up separately from confirmed survival and failure. Prepare cohort follow-up in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Unknown plants must not be treated as surviving or dead.
Lower =100 × known survivors / original cohort. Upper =100 × (known survivors + unknown) / original cohort. Survivors + known failures + unknown = original cohort; replacements do not enter it.
These bounds account for unknown status; they are not statistical confidence intervals. Use actual follow-up dates and distinguish cohort membership from repeated visits.
Other required records: Cohort; planted plants; survivors; replacements; follow-up date; block.
Compare supplied sheet-and-rill erosion estimates for detailed field assessment.
Verified published formula · USLE factor product
What the selected record shows. Estimated annual sheet/rill loss: 15.641 t/ha/year.
Next step. Check local factor and site evidence before selecting a detailed erosion assessment. Prepare assessment brief in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
The estimate does not establish landslide risk, all sediment loss or a treatment design.
R × K × LS × C × P, using a mutually consistent SI factor set.
This USLE factor product is not a full RUSLE2 run, measured loss, delivered sediment, gully loss or landslide forecast. Local factors and uncertainty need review.
Other required records: Erosivity; soil erodibility; slope; cover; support practices; block area.
United States Department of Agriculture Forest Service · A Guide for Predicting Sheet and Rill Erosion on Forest LandGovernment publication · 1980 technical publication SA-TP 11; Universal Soil Loss Equation, printed page 2; metric conversion appendix, printed page 40
The historical source verifies the factor product. Local factor choice and suitability still need confirmation; this is not a full RUSLE2 implementation.
Check harvesting dates against usable resources and prerequisites.
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.
A schedule does not establish maturity, safe weather or crop quality.
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: Block maturity; weather; labour availability; processing capacity; quality requirements.
Identify an unusual pest observation against the supplied comparison basis.
What the selected record shows. Difference: 6 affected plants per 100 inspected.
Next step. Check the unusual observation and its comparison basis. Prepare investigation brief in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A deviation alone does not diagnose a pest outbreak or justify treatment.
Later/comparison value minus Comparable reference value. Relative change = 100 × difference / Comparable reference value when the earlier value is positive.
Other required records: Crop; symptoms; diagnostic result; incidence; survey effort; historical baseline.
Compare gross made-tea output with matching received green leaf.
What the selected record shows. Made-tea mass; declared outgoing moisture basis: 270 kg; Green-leaf mass received; declared incoming moisture basis: 1,200 kg. This gives 22.5 %.
Next step. Check matching outputs, denominators and operating conditions. Prepare performance comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
The ratio does not establish moisture-adjusted process efficiency or a loss cause.
Gross recovery = 100 × made-tea mass / received green-leaf mass, on the explicitly stated incoming and outgoing moisture bases. This is not a dry-matter conversion efficiency.
The fictional tea example uses 1,200 kg green leaf and 270 kg made tea. The unrepresented mass includes water removed and cannot all be called waste.
Other required records: Fresh input; saleable output; moisture; by-products; process losses; period.
Compare energy use per matching product quantity.
What the selected record shows. Energy per product: 0.756 kWh/kg.
Product mix, quality and operating conditions must match before inferring efficiency.
Energy/output; water/output; and 100 × output/material input. Separate denominators and units; do not sum these efficiencies.
Other required records: Product output; energy kWh; water cubic metres; process stage; period.
Check lot observations against the cited product specification and method.
What the selected record shows. The supplied Fictional lot moisture, wet-basis mass percent result is 13 %. Its stated comparison range is 0 to 12 %. Outside example comparison bounds.
An example bound does not certify the lot or establish a legal nonconformity.
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; quality parameter; test method; result; buyer specification; traceability.
Compare estate-adaptation cash flows under explicit assumptions.
Verified published formula · Discounted cash-flow NPV
What the selected record shows. At the supplied 8% annual discount assumption, the five-year cash flows and residual value give 109,847.353 LKR net present value after the initial investment. The figure compares cash flows under these assumptions.
Next step. Review the cash flows, discount assumptions and constraints. Prepare cash-flow comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
Net present value does not establish avoided climate damage or technical suitability.
NPV = −initial investment + sum of year1…5 net cash flows discounted at the stated annual rate, including residual value once in year5.
Match currency, price year, real/nominal basis and cash-flow timing. The example rate and five-year horizon are assumptions, not institutional financing terms; no credit approval follows.
Other required records: Exposure; water availability; crop risks; options; costs; expected benefits.
Food and Agriculture Organization of the United Nations · Guidelines for defining financial economic environmental and social informationInstitution publication · Sections 2.2.2 and 2.2.3, discounting and Net Present Value
The five-year horizon, discount rate and cash assumptions are local settings. Verification does not approve an investment or loan.
Find missing evidence for a competent occupational-hazard referral.
What the selected record shows. The required evidence is incomplete for this worker safety case. The items below identify what must be obtained or reconciled.
The prototype does not certify a safe workplace or authorise an operation.
Show the hazard, exposure and verified controls separately. No generic score, probability, diagnosis, site clearance or official warning is derived from a count.
Other required records: Task hazards; exposure; incident evidence; controls; inspections; requirements.
Find estate households without confirmed access to the stated service.
What the selected record shows. 30 households are known to be uncovered; 5 have unknown coverage. 65% are confirmed covered.
Coverage does not establish quality, fairness or benefit.
Other required records: Household frame; safe water; sanitation; housing condition; verified service access.
Identify equipment-maintenance cases past their 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.
Age alone does not establish failure risk or a safe operating condition.
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: Asset; condition; failure history; service criticality; parts; repair cost.
Trace broken source links between the stated estate 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, conformity or actual recall scope.
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: Block ID; harvest lot; factory lot; shipment; transfer documents; certification.
Review carbon-stock changes with the stated area and pool coverage.
Verified published component · Carbon stock-difference component
What the selected record shows. Carbon stock change: -850 t C.
Next step. Review the matched pools, area and observation periods. Prepare carbon comparison in the prototype creates a visible, downloadable draft. It is unassigned and not sent.
A stock change does not establish a verified emission reduction or carbon credit.
(Later carbon density − earlier carbon density) × same inventory area, with identical pools, method and boundaries.
Inventory plots, allometry and uncertainty remain required evidence. Stock change is not an issued carbon credit, additionality test or payable service.
Other required records: Tree inventory; soil measurements; models; carbon fractions; area; uncertainty.
Intergovernmental Panel on Climate Change · 2006 IPCC Guidelines Volume 4 Chapter 2Institution publication · Section 2.3.1.1, equation 2.8, stock-difference method
The screen reports the period total. IPCC annualisation requires elapsed years. Pools, inventory inputs and local application still need confirmation.
Follow up unresolved estate-development comments and participation barriers.
What the selected record shows. 16 unresolved issue(s). 71.579% responded; response is not consent. Review the issue references and participation barriers.
Responses do not establish agreement or resolve affected rights.
100 × distinct respondents / invited people. Record unresolved issues individually; one respondent may raise several issues.
Response, attendance and silence are not consent. Participation does not transfer decision authority or settle rights.
Other required records: Proposal; affected communities; consultation; objections; commitments; conditions.
Find missing classification meanings and source versions for estate blocks.
What the selected record shows. The required evidence is incomplete for this estate classifications case. The items below identify what must be obtained or reconciled.
Matching class labels do not establish the same land use or boundary.
Other required records: Block ID; crop labels; planted area; source edition; definitions; steward.
Source. Sri Lanka publication.
Data needed. Facility and incident date, injury or dangerous occurrence record, worker status and the applicable reporting form.
Method. Check the incident against the Department of Labour’s factory accident and dangerous occurrence reporting requirements. Use the prescribed notice when the event falls within scope.
Worked example. An estate factory reports an injury. Record the circumstances and check the Department of Labour’s reporting criteria and prescribed notice.
Next step. Send the notification through the authorized factory reporting process and retain the reference for follow-up.
Department of Labour, Industrial Safety Division. Factory accident and dangerous occurrence notifications and prescribed forms.
Confirm that the facility and incident fall under the Factories Ordinance, the reporting deadline and access to incident records.
