ISO 17100:2015 · บริการแปลภาษา

ISSUED BY · International Organization for Standardization

ISO 17100:2015 is the international standard for translation services. It specifies requirements for translation service providers including human and technical resources, quality and project management process, engagement process from quotation to delivery, and contractual framework. The standard requires the Translation–Editing–Proofreading (TEP) workflow — three distinct stages each performed by competent linguists.

For Othello, ISO 17100 governs every translation deliverable. Critical for institutional clients running formal procurement processes — particularly Big Law, SET-listed corporate disclosure, regulatory filings, government RFPs, and cross-border legal translation where audit-traceable workflow is a procurement gate.

ATA Affiliated · American Translators Association

ISSUED BY · ATA · Alexandria, Virginia, USA · founded 1959

The American Translators Association (ATA) is the largest professional association of translators and interpreters in the United States, founded in 1959. ATA Corporate Member status signals US-market recognition and adherence to ATA’s professional standards and Code of Ethics and Professional Practice.

For Othello, ATA affiliation matters most for US government translation work (the founding client segment), US-headquartered multinational subsidiary work, US law firm cross-border engagements, and bilingual EN/TH legal/financial translation where US-market terminology conventions apply.

ATC Accredited · Association of Translation Companies

ISSUED BY · ATC · London, UK · founded 1976

The Association of Translation Companies (ATC) is the UK’s leading trade body for translation and localisation companies, founded in 1976. ATC Accredited Membership is awarded to translation companies meeting the ATC Code of Professional Conduct and operating standards covering quality management, data security, project management, and commercial conduct.

For Othello, ATC accreditation matters most for UK and EU institutional clients, European Big Law cross-border work, EU multinational subsidiaries operating in Thailand, EU CSRD-style sustainability disclosure work, and UK PACT programme engagements. ATC also intersects with GDPR compliance — the ATC’s data security standards align with GDPR’s data protection requirements.

GDPR Compliant · EU General Data Protection Regulation

REGULATION · EU Regulation 2016/679 · effective 25 May 2018

The EU General Data Protection Regulation (GDPR) is the EU’s primary data protection law, applying to any organisation processing personal data of EU/EEA residents — regardless of where the organisation is located. For Othello, GDPR compliance is required by EU institutional clients, European Big Law engagements, EU multinational subsidiaries with European data flows, and EU CSRD-related disclosure work.

Operational GDPR compliance covers: lawful basis for processing; data minimisation; data retention with secure deletion; cross-border transfer mechanisms (Standard Contractual Clauses); incident response and breach notification within 72 hours; data subject rights (access, rectification, erasure, portability, objection); and a designated data protection contact point.

PDPA Compliant · Thai Personal Data Protection Act

LAW · PDPA B.E. 2562 (2019) · effective June 2022

The Personal Data Protection Act B.E. 2562 (2019) — commonly referenced as Thailand’s PDPA — is Thailand’s primary data protection law, structurally modelled on GDPR with Thai-specific adaptations. The Act took full effect in June 2022. PDPA compliance is required for any entity operating in Thailand processing personal data of Thai residents.

Operational PDPA compliance covers similar substantive ground to GDPR: lawful basis for processing, data minimisation, retention limits, cross-border transfer mechanisms (PDPA Sections 28–29), incident response, data subject rights, and a Data Protection Officer designation. Specific Thai-language consent forms where personal data processing is consent-based, registration with the Personal Data Protection Committee (PDPC) for certain activities. For Othello’s SET-listed and Thai SOE clients, PDPA compliance is a hard procurement gate.

Question 03 · Founded 2020

Founded shortly before the pandemic. On US government translation work.

Othello was founded in Bangkok in 2020, shortly before the COVID-19 pandemic. The first contracts were translation services for the US Centers for Disease Control and Prevention (CDC) and the US State Department operating in Thailand. US government translation work is structurally the highest-precision, highest-confidentiality, lowest-tolerance-for-error commercial translation work available. Establishing the firm against that standard on day one set the operating discipline that still governs every engagement today.

USG-ORIGIN STANDARD · BANGKOK · 2020 FOUNDING

The founding standard was set by the work itself: precision, confidentiality, zero margin for error.

US government translation work is operationally exacting. Federal procurement regulations — the Federal Acquisition Regulation (FAR) and the United States Agency for International Development Acquisition Regulation (AIDAR) — impose specific requirements on documentation handling, conflict-of-interest disclosure, security clearances where applicable, contractor verification, and audit trail. The translation work itself runs to similar standards: public health documentation (CDC), diplomatic and consular materials (State Department), regulatory communications, training materials for Thai government counterpartsและ cross-border legal documentation.

The pandemic tested every translation firm. It accelerated the operational rigour at Othello — confidential public health work, cross-border coordination, and the deliberate decision in 2021 to extend beyond government work to Big Law and SET-listed corporate clients brought the same precision discipline to the private sector.

The founding standard is the differentiator · The same precision and confidentiality discipline that governs US government translation work governs every engagement at Othello today — Big Law, SET-listed corporates, Thai SOEs, multinational financial institutions, the UN system, and the ESG Advisory practice launched in 2026. This is structurally why Bangkok-based, in-house, mutual-NDA-from-first-email is the operating standard rather than an optional commercial commitment.
Question 04 · Bangkok Office

One office. Si Lom · North Sathon · the Bangkok CBD.

Othello operates from one office in the Bangkok CBD — Unit 12-03, Chartered Square, 152 N Sathon Rd, Si Lom, Bang Rak, Bangkok 10500, Thailand. The location is operationally deliberate: walkable to most SET-listed headquarters, walkable to Bank of Thailand, SEC Thailand, and the Stock Exchange of Thailand, walkable to the major Thai bank headquarters, and walkable to most Big Law Bangkok offices. For confidential engagements, in-person source-material handover is the default rather than the exception.

Question 05 · Five Reasons Clients Return

Five structural advantages. Things that compound over multi-year engagements.

Beyond the credentials, the founding story, and the location, Othello is structurally differentiated on five vectors that compound over multi-year engagements — meaning Year 2+ work delivers materially better economics and quality than Year 1. Each one took years to build and is hard to copy: founding-USG provenance, bilingual lockstep discipline, in-house bench, translation-memory compounding, and the NDA-first commercial standard.

01

USG-grade รากฐาน

Founding work with the US CDC and US State Department in Thailand established the precision and confidentiality standard from day one. The same discipline now runs Big Law, SET-listed, and ESG advisory engagements.

02

สองภาษา EN/TH lockstep

Every deliverable drafted in parallel English and Thai versions in lockstep — not English-then-translated, not Thai-then-translated. Critical for SET-listed 56-1, sustainability reports, and SPO documentation where regulators and investors read different versions.

03

In-house bench

100% in-house specialist bench. ESG advisory anchored by named credentials (IFRS S2, ISO 14064 Lead Auditor, AA1000AS ACSAP, GRI 2021, TGO). Translation anchored by ISO 17100 certified linguists. No work outsourced to freelancers.

04

TM compounding

Five years of bilingual annual reports, sustainability reports, and ESG documentation produce a Translation Memory asset that delivers compounding savings on multi-year client programmes. New work re-uses substantively-translated material at much lower cost.

05

NDA from first email

The commercial standard. Mutual NDA is signed before any source material crosses from client to Othello — including at RFP stage. Documented as standard procurement practice for Big Law, listed companies, and government clients.

Common Questions · click to expand

สิ่งที่ทีมจัดซื้อ verify before engagement.

Nine questions Othello answers before the proposal arrives — click any question to expand the answer.

01 When exactly was Othello founded, and what defines USG-origin standard? +

Othello was founded in 2020 in Bangkok, shortly before COVID-19. First contracts: translation services for the US CDC and US State Department operating in Thailand. “USG-origin standard” refers to operational discipline established by founding the firm against US government translation work requirements on day one — federal procurement regulations (FAR / AIDAR) impose specific requirements on documentation handling, conflict-of-interest disclosure, security clearances where applicable, contractor verification, audit trail, and confidentiality.

The translation work itself — public health documentation, diplomatic and consular materials, regulatory communications, training materials, cross-border legal documentation — all runs to similarly exacting standards. Establishing the firm against this standard from day one set the operating discipline that still governs every engagement today.

02 Where is Othello’s office and is in-person work available? +

Othello operates from one office in the Bangkok CBD — Unit 12-03, Chartered Square, 152 N Sathon Rd, Si Lom, Bang Rak, Bangkok 10500, Thailand. Phone +66 02-859-2145 · Email [email protected] · Hours Monday–Friday 09:00–18:00 ICT. The North Sathon location is walkable to MRT Sala Daeng and BTS Sala Daeng (~7 minutes), most SET50 and SET100 head offices, Bank of Thailand and SEC Thailand, the Stock Exchange of Thailand, KBank/SCB/BBL/BAY/KTB headquarters, and most Big Law Bangkok offices.

In-person work is available and is the default for confidential engagements — particularly Big Law and SET-listed disclosure work where digital transmission is sometimes structurally inappropriate.

03 What does ISO 17100:2015 actually require? +

ISO 17100:2015 is a translation-services-specific international standard, not a generic quality management standard. ISO 9001 covers any organisation’s quality management at a generic level; ISO 17100 specifies the actual translation workflow, linguist competencies, terminology management, and engagement process specific to translation services.

Substantive requirements: (1) Translator competence — defined education/experience/language qualifications; (2) TEP workflow — Translation–Editing–Proofreading as three distinct stages with separation between translator and editor; (3) Project management; (4) Quality management — defined QC processes, error categorisation, evidence trail; (5) Technology infrastructure — translation memory, terminology management; (6) Engagement framework. For institutional procurement teams, ISO 17100 is the substantive translation standard that matters.

04 What’s the difference between ATA Affiliated and ATC Accredited? +

Two separate professional bodies with different regional anchoring. The American Translators Association (ATA) is the US-anchored professional association, founded 1959, Alexandria VA. The Association of Translation Companies (ATC) is the UK-anchored trade body, founded 1976, London. ATC Accredited Membership requires meeting the ATC Code of Professional Conduct covering quality management, data security, project management, and commercial conduct.

The two are complementary, not duplicative. ATA matters for US-market work; ATC matters for UK/EU-market work. Carrying both is structurally significant — most Thailand-based translation firms carry one or neither.

05 How does GDPR + PDPA work together for a Bangkok-based firm? +

GDPR has extraterritorial scope — it applies to any organisation processing personal data of EU/EEA residents, regardless of where that organisation is located. Thailand’s PDPA (B.E. 2562 / 2019, effective June 2022) is structurally modelled on GDPR with Thai-specific adaptations.

The two regimes operate in parallel: GDPR for EU/EEA-resident data subjects, PDPA for Thai-resident data subjects. For multinational engagements where both apply (typical for SET-listed Thai corporates with European investor coverage), the operational compliance regime is the union of the two — meeting whichever requirement is more stringent on each operational dimension.

06 ทำไม in-house bench important? +

Three structural reasons. (1) Confidentiality: Big Law, US government, SET-listed pre-disclosure, and ESG advisory work involves source material that cannot operationally be shared with external freelancers, overseas vendors, or LLM-based processing pipelines that retain source data. (2) Methodology consistency: ESG Advisory methodology credentials (IFRS S2, ISO 14064, AA1000AS, GRI, TGO) are held by named individuals on the in-house bench — outsourced work cannot carry the same anchoring. (3) TM compounding: Five years of bilingual annual reports produce a TM asset that delivers compounding savings on multi-year client programmes — but only if the bench using the TM is the same bench that built it. Freelance rotation breaks the compounding.

07 How are the five firm credentials independently verifiable? +

Each credential has a different verification mechanism. (1) ISO 17100:2015 — certification by accredited certifying body; certificate number and certifying body provided at procurement scoping. (2) ATA Affiliated — verifiable through ATA member directory at atanet.org. (3) ATC Accredited — verifiable through ATC member list at atc.org.uk. (4) GDPR Compliant — no single GDPR certification body; compliance evidenced through GDPR-aligned policies, data processing register, vendor due diligence. (5) PDPA Compliant — no PDPC formal certification scheme; compliance evidenced through PDPA-aligned policies, Thai consent framework, DPO contact.

For the FTSE Russell ESG 4.0/5.0 cross-anchor proof — independently verifiable through FTSE Russell’s published score data.

08 Does Othello carry ISO 9001 as well? +

The substantive translation services quality standard is ISO 17100:2015 — translation-specific, more rigorous on translation workflow than ISO 9001’s generic quality management. For procurement evaluation, ISO 17100 covers the substantive ground that matters: translator competence requirements, TEP workflow, terminology management, technology infrastructure, and engagement process. ISO 9001 alone does not cover this substantive translation-specific ground.

The five firm-level credentials (ISO 17100, ATA, ATC, GDPR, PDPA) operate alongside the bench-level methodology credentials (IFRS S2, ISO 14064, AA1000AS, GRI, TGO, VERRA). Together they form the substantive verifiable credentialing. Where a specific RFP requires ISO 9001 separately, the requirement is met at engagement scoping — discuss procurement requirements at first contact.

09 How do we engage Othello — first contact through engagement-begin? +

Four steps, typically 3–10 business days from first contact to work beginning. (1) First contact via [email protected], phone +66 02-859-2145, or contact form — sets up a 30-minute scoping call. (2) Mutual NDA signed — Othello template available on request; client templates reviewed and signed within one business day if standard terms apply. NDA signed before any source material crosses.

(3) Scope brief + source material exchange under NDA — bench reviews source material, identifies methodology approach, named specialists. For ESG advisory engagements, specific in-house specialist(s) on the engagement letter are named, and their individual credentials can be independently verified. (4) Quote delivered within one business hour of receipt of source material and signed NDA — fixed-fee structure, scope locked, timeline committed. Standard RFP response is 3–5 business days.
