About this review
This is a demonstration for client feedback and development planning. Public data keeps its source and date. Samples stay clearly marked. Test drafts, uploaded files and review answers stay in this browser and website address. User-management screens create no real accounts or permissions. The real SHARED system and its records are unchanged.

Review 28 Sri Lanka decision proposals.
Verified means the published formula was checked against its source. For a component, only the named part is verified. Confirm local settings and use in the list below.
| Method and status | Published source | Local use to confirm |
|---|---|---|
| USLE factor product Verified published formula | United States Department of Agriculture Forest Service 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. |
| Enterprise gross margin Verified published formula | Food and Agriculture Organization of the United Nations Chapter 4, Gross margin and section 4.7.1 | Per-hectare and variable-cost break-even outputs are algebraic rearrangements. Local costs, prices and interpretation still need confirmation. |
| Discounted cash-flow NPV Verified published formula | Food and Agriculture Organization of the United Nations 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. |
| Carbon stock-difference component Verified published component | Intergovernmental Panel on Climate Change 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. |
| Soil-carbon stock with volume correction Verified published formula | Intergovernmental Panel on Climate Change Section 4.3.3.5.4, equation 4.3.3, printed page 4.106, PDF page 18 | The screen converts carbon percent to a fraction and uses the published coarse-fragment volume convention. Sampling and bulk-density conventions still need confirmation. |
| Difference-in-differences arithmetic Verified published formula | World Bank 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. |
| Sample coefficient of variation Verified published formula | National Institute of Standards and Technology United States 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. |
| HHI concentration component Verified published component | United States Department of Justice 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. |
| Matched-pair RMSE Verified published formula | Environment and Climate Change Canada Displayed RMSE equation and definitions of forecast, observation and verification count | Local verification periods, observation quality and forecast applicability still need confirmation. |
| Binary Brier score and skill component Verified published component | Japan Meteorological Agency Sections A.3.1 and A.3.2, equations A.3.1 and A.3.3, printed page 239, PDF page 7 | The Brier score is checked for binary events. The prototype permits a supplied reference forecast; confirm its independent baseline and comparability before interpreting skill. |
| Crop evapotranspiration ETc component Verified published component | Food and Agriculture Organization of the United Nations Chapter 5, Crop coefficient approach, equation 56 | This verifies the ETc component only. Local water-balance allowances, coefficients and operating decisions still need confirmation. |
| Weighted estimation component Verified published component | United Nations Statistics Division Chapter 9, paragraphs 38 and 39, printed page 9-9, PDF page 417; Chapter 8 weighting | Local weights, population coverage, design variance and ratio-yield interpretation still need confirmation. Positive illustrative weights do not demonstrate every calibration design. |
| IWA water-balance components Verified published component | Asian Development Bank Figure 4, printed page 15; Annex 1 Water Balance Definitions, printed pages 39–41, PDF pages 47–49 | Apparent-loss estimates and the residual real-loss estimate remain local inputs with measurement uncertainty. |

Data needed from institutions
Use this list to follow up on the 41 draft dataset pairs.
| Data owner | What to provide |
|---|---|
| Department of Export Agriculture | Provide the 2025 district and crop figures for the 100 affected entries. Give crop extent in hectares and production in metric tonnes, or explain the blank. Both figures are blank for 81 entries. Only production is blank for 19. 2025 extent table · 2025 production table |
| Southern Province Ministry of Agriculture | Provide the missing March and April Yala 2026 cultivation progress in hectares, or explain the blank, for the 79 affected crop and district entries in Galle, Matara and Hambantota. Confirm that April row 54 is Wing bean. March CropIX report · April CropIX report |
| Irrigation Department | Provide the Alikota Ara effective storage reading for 1 April 2025 in acre-feet, or confirm why the Yala series leaves it blank. Yala reservoir series |
| Export Development Board | Provide the combined fish and fisheries share of merchandise exports and the total merchandise exports used to calculate it. We need the 10 full years from 2016 to 2025 and January to September 2026. Include the basis for the published figures. Export Performance Report |
Already explained by the source
| Data owner | What the source explains |
|---|---|
| Forest Department / Department of Census and Statistics | The six 2024 forest-class figures are in the newer edition. The earlier edition ends in 2023, so a comparison between editions uses 2019–2023. The six 2024 figures need no new data. Earlier Table 5.29 · Newer Table 5.29 |
| Department of Meteorology | Katunayake’s 17:30 observation on 10 November 2026 records TRACE for rainfall since 08:30. Keep the trace as reported. Request the original station record only if a numeric amount is needed. Department observations · Saved review record |
| Department of Census and Statistics | Jaffna had no paddy cultivation in Yala 2023 or Yala 2024, so average yield does not apply. This explains four entries across the Department of Agriculture and Farmer Organizations dataset pairs. No new yield figures are needed. Table 5.20, note 1 |
Client and expert decisions
These decisions remain pending in Institution review. Each decision should state what was checked, who checked it, the outcome and any conditions. One review can cover the same method used by several screens.
| Topic | What to confirm | Who |
|---|---|---|
| Scope and institutions C01, C02, C12 | Confirm the final features, proposed decisions, participating institutions and what stays in existing tools. | Client |
| Responsibilities C02 | Name who owns data, submits records, reviews them and approves sharing. | Client and institutions |
| Maps and boundaries C03 | Source studies report 1,533 and 1,584 GN divisions. Which dated programme roster, official codes and boundary edition apply? Who maintains them? SRS geographic rules. The dated rosters and crosswalk are needed. | Data custodian and GIS expert |
| Data sources C04 | Confirm datasets, fields, units, update frequency and access or sharing conditions. | Source institutions |
| Privacy C05 | Confirm access to personal records, sensitive locations and retention periods. | Client and privacy specialist |
| New or changed calculations E01 | Review proposed scores, weights, thresholds, missing-value rules and method changes. For published methods, confirm local inputs, units, settings and intended use. | Relevant expert or statistician |
| Land soil and water methods E02 | Confirm local suitability, sampling, laboratory methods and model factors. | Relevant domain experts |
| Ecosystem services and PES E03 | Confirm eligibility, rights, rates, safeguards, verification and payment authority. | Client and relevant experts |
| Indicators and payments C10 | Confirm indicator definitions, acceptance measures, milestones and payment weights. | Client and monitoring or finance specialists |
| Languages and access needs C06 | Confirm wording, supported devices and accessibility requirements. | Client and representative users |
| Technical choices and service targets C07, C08 | Agree architecture, hosting, operator, costs, performance, security and recovery targets. | Client and technical adviser |
| Complaints and appeals C09 | Confirm receiving officers, response times and the appeal process. | Client |
| Final SRS acceptance C11 | Confirm consultation comments, agreed revisions, validation, final presentation and final acceptance. | Authorized client representative |
Live-system security, load and recovery tests belong to implementation. The SRS needs agreed requirements and a test plan. No separate expert approval is needed for each mock screen or repeated calculation.
Source details to confirm
LUPPD: the alternative publications provide planning context. The applicable local planning procedure still needs confirmation under C04 and E02.
HARTI: the published prices support the quoted observations. They do not automatically support proposed volatility, spread or other analysis; review these under C04 and E01.
