Case studies are anonymised by structural necessity, not stylistic preference. The same five reasons documented on the Our Clients page apply: SET-listed material non-public information regime under SEC Thailand insider information framework, Big Law privilege regime, UN-system multilateral confidentiality protocols, US-government FAR-grade contractor verification discipline, and SET-listed client RFP positioning protection. Publishing the client name publicly would weaken the client’s competitive positioning and breach engagement-letter confidentiality.

What procurement panels can get instead is the substantive evidence package — the three-pillar methodology + track record + reference pathway structure documented above. Direct client identity disclosure is available under mutual NDA at procurement evaluation stage through the five-step reference pathway: procurement panel submits formal reference request → Othello signs procurement-team NDA → reference scope confirmed → client consent secured → procurement panel contacts client reference directly under NDA-protected scope. Othello is not party to that reference conversation by structural design.

FTSE Russell ESG Scores are independently published on the LSEG (London Stock Exchange Group) data infrastructure and accessible through Bloomberg Terminal, Refinitiv Eikon (Refinitiv Workspace), and direct LSEG data subscription. Procurement evaluation panels with Bloomberg or Refinitiv access can pull the FTSE Russell ESG Score for SET-listed Thai issuers directly — the score is published as 0.0–5.0 with breakdown by Theme and Pillar.

The SET-listed healthcare operator with 4.0/5.0 ESG Score in 2025 is identifiable through this published data — but Othello does not publicly broadcast the specific issuer name on this website for the structural reasons above. Under the reference pathway at procurement evaluation, the specific issuer identity is disclosed under mutual NDA, and procurement panels can then cross-verify the publicly-disclosed FTSE Russell score against the specific issuer’s published rating on Bloomberg / LSEG. The vendor-side claim and the third-party public registry record converge on the same issuer — this is the substantive verification design.

The substantive engagements documented in the cases above are multi-year programmes, not one-shot deliverables. The flagship rating-agency triple-anchor case (Case 01) runs across the full FTSE Russell SID portal annual cycle (June–March) plus parallel SET ESG and Thai IOD CGR cycles — that’s a 12-month minimum engagement cycle, typically renewed annually under multi-year engagement letter. The AA1000AS sustainability assurance cases (Case 02) run multi-cycle across three SET-listed issuers — typically 3+ year continuous assurance practitioner engagements.

Multi-year retainer continuation is one of the eight track metrics documented on this page (Metric 08) — the substantive performance signal is not just “did the engagement happen” but “did the engagement renew across multiple cycles”. Programme renewal across multi-year cycles is the structural credibility signal that single-deliverable engagements cannot match. See the Annual Programme structure on How We Quote for the one-engagement-letter multi-year bundle architecture.

The eight sectors are all represented in substantive Othello engagement track record, distributed across the six anonymised cases and the broader engagement portfolio. The case-study selection above prioritises publicly verifiable outcomes over comprehensive sector coverage — which is why Case 01 anchors healthcare (FTSE / SET / Thai IOD all publicly verifiable for the SET-listed healthcare operator), Case 03 anchors healthcare again (MoPH 904 hospitals), and Case 04 anchors cross-sector (100+ SET Climate Care adopters distributed across multiple SET sectors).

For sectors not explicitly documented in the six case studies above (e.g. real estate & REITs, tech & telecoms, financial services), relevant case-study material is available under mutual NDA at procurement evaluation — same three-pillar evidence structure (methodology + track record + reference pathway) applied to the specific sector your procurement panel is scoping. The page documents the publicly verifiable subset; the full portfolio is accessible through the reference pathway.

Yes — the six anonymised cases on this page are accessible without NDA. Substantive scope, methodology approach, outcome metric, and public-record verification path are all documented above. For procurement evaluation panels at SET-listed corporates, multilateral institutions, Big Law firms, or government bilateral programmes, this page is the first-pass anonymous evidence package — substantive enough to inform vendor shortlisting decisions before formal RFP scoping conversations.

For sector-specific anonymised cases not documented on this page, the operational pathway is: enquiry → NDA-from-first-email (Othello signs procurement-team NDA within 1 business day, or proposes mutual NDA template) → sector-specific anonymised case-study package shared under NDA scope. The case-study material under NDA includes the same three-pillar structure but with additional substantive detail — engagement timing, methodology specialist composition, deliverable-by-deliverable breakdown, KPI commitments referenced in the engagement letter. The progression from public-page anonymous → NDA-scope sector-specific → reference pathway client-direct is the standard institutional procurement evaluation flow.

AccountAbility AA1000AS v3 sustainability assurance work operates against the AA1000AP 2018 four-principle framework — Inclusivity (engagement with stakeholders), Materiality (identification of material sustainability topics), Responsiveness (responses to stakeholder concerns), and Impact (measurement and management of impacts on stakeholders). The assurance level is typically limited assurance under ISAE 3000 framework alignment — the assurance provider gathers sufficient appropriate evidence to express a conclusion that nothing has come to attention that would cause the practitioner to believe the disclosure is materially misstated.

The published opinion statement appended to the issuer’s annual sustainability disclosure documents the assurance scope (which AA1000AP principles assessed, which substantive disclosures examined), the assurance level (limited or reasonable), the evidence gathering methodology (sampling-based, document review, management interview), and the conclusion. Othello’s bench includes Accredited Sustainability Assurance Practitioner (ACSAP) credentials through AccountAbility’s public registry — the assurance practitioner credential is independently verifiable through AccountAbility’s published ACSAP list. The three SET-listed issuers documented in Case 02 have AA1000AS opinion statements appended to their annual sustainability disclosure published on their IR websites and through SET regulatory filings.

Three independent rating instruments, three different framework approaches. FTSE Russell ESG Scores apply a global methodology — 14 Themes (Climate Change · Pollution & Resources · Water Security · Biodiversity · Supply Chain E · Supply Chain S · Health & Safety · Human Rights · Customer Responsibility · Labour Standards · Anti-Corruption · Corporate Governance · Tax Transparency · Risk Management) × 3 Pillars (E / S / G) × 300+ indicators × 173 Subsectors. Score range 0.0–5.0. Annual SID portal cycle June–March with ~4-week feedback round response window.

SET ESG Ratings is the Stock Exchange of Thailand’s published sustainability rating for SET-listed companies — AAA / AA / A / BBB tiers, annual cycle, focused on Thai listed-company applicability. Thai IOD CGR is the Thai Institute of Directors Corporate Governance Report — 5-Star / 4-Star / 3-Star scale, annual assessment, focused on corporate governance practice (board structure, shareholder rights, transparency, accountability). The cross-anchor case (Case 01) demonstrates that the same operator can achieve top-tier outcomes across all three independent rating instruments simultaneously — which is the substantive credibility moat that single-rating outcomes cannot match.

Verra’s Plastic Waste Reduction Standard is a relatively new voluntary carbon market methodology — the first standard methodology for issuing tradable plastic-waste reduction credits, recognising activities that prevent plastic waste from entering the environment or recover and recycle plastic that would otherwise be mismanaged. Thailand’s first VERRA-certified plastic credit project is first-of-kind in the Thai voluntary carbon market — substantive methodology innovation, first-mover regulatory engagement with Verra, and template-setting for subsequent Thai plastic credit projects.

The substantive significance for procurement evaluation: first-of-kind project registration under a Verra programme requires methodology-credentialed bench depth, validation/verification body coordination through Verra’s VVB network, additionality demonstration under Verra’s project registration framework, and baseline measurement methodology that withstands Verra technical review. This is structurally why the case anchors voluntary carbon market methodology authority — first-of-kind projects in voluntary carbon markets cannot be delivered without methodology-credentialed bench depth, which is itself a procurement signal at institutional sustainability advisory tier.

The Ministry of Public Health publishes the platform’s adoption statistics and methodology documentation on the Ministry-side public information channels. Othello’s methodology contribution is documented within the substantive engagement materials and through the platform’s published methodology architecture — health-sector adapted GHG Protocol Corporate Standard methodology, Scope 1+2 facility emissions baseline, energy intensity benchmarking framework. The Ministry of Public Health is the platform owner; Othello is the methodology contributor.

For procurement evaluation purposes, the public verification path is the Ministry-published platform data documenting the 904 hospital onboarding count — that is the public outcome record. Direct reference contact with the Ministry’s relevant procurement contact is available under mutual NDA at procurement evaluation stage. The substantive 904-hospital scale is the methodology-adoption track metric — what procurement panels evaluate is whether a vendor can deliver methodology work that scales to national platform adoption across a regulated sector. This case anchors that scale dimension.

The case-study evidence package operationalises Othello’s one operating standard applied to procurement evaluation. The three-pillar structure (methodology + track record + reference pathway) is the substantive answer to the institutional procurement evaluation question — how does a vendor demonstrate substantive engagement evidence without breaching NDA discipline? The pillars work in sequence: methodology shows what was done substantively (against recognised international frameworks), track record anchors the outcome on a third-party public registry (independently verifiable), and reference pathway provides direct client contact under mutual NDA (where required for procurement evaluation depth).

Cross-page evidence convergence: the six cases on this page anchor the four institutional client segments (SET-listed flagship + Big Law + UN-multilateral + Government), demonstrate the 38 methodology standards across 16 institutional bodies the bench operates against, and substantiate the one-stop-shop Annual Programme bundle through public-record outcome anchoring. One operating standard. Six anonymised cases. Eight sectors. Eight track metrics. Three-pillar evidence package. The structure is operationally what allows NDA-respectful disclosure to clear procurement evaluation panels at SET-listed institutional procurement tier.
