A Due Diligence Questionnaire (DDQ) is a structured document containing 50-200 questions that organizations use to assess the risks, compliance status, and operational capabilities of potential business partners, vendors, or acquisition targets. Organizations using AI-native automation platforms see speed improvements of 60-80% in DDQ response times, with some reducing InfoSec review cycles from 3 weeks to 1 day. Effective DDQ management requires centralized knowledge repositories, cross-functional collaboration, and clear ownership across finance, legal, compliance, and security teams.

A Due Diligence Questionnaire (DDQ) is a structured document that organizations use to assess potential risks, compliance status, and operational capabilities of business partners, vendors, or acquisition targets. At Arphie, we help organizations accelerate DDQ response times through AI-native automation.
DDQs typically contain 50-200 questions covering financial stability, regulatory compliance, data security, operational risks, and ESG policies. Organizations handling multiple DDQs annually face significant time and resource demands in responding accurately and consistently.
While all three document types involve Q&A workflows, their purposes differ significantly:
Due Diligence Questionnaires (DDQs) focus on risk assessment and compliance verification. They're typically issued by investors, acquirers, or regulated entities evaluating potential business relationships.
Requests for Proposal (RFPs) evaluate capabilities and pricing for specific projects or services. These are procurement-focused and compare competing vendors.
Security Questionnaires drill deep into cybersecurity controls, often containing 200+ technical questions about encryption, access controls, and incident response.
DDQs require cross-functional collaboration—pulling information from finance, legal, compliance, and operations teams—making them strong candidates for AI-native automation.
Response speed directly affects business outcomes. Organizations that reduce DDQ response times can close strategic partnerships faster and improve deal velocity. Teams using automation for security questionnaires in particular are seeing weeks of reduction in deal cycle times. One customer shrunk InfoSec review time from a 3 week queue to just 1 day turnarounds.
Teams switching from legacy RFP software solutions to AI-native platforms like Arphie typically see speed and workflow improvements of 60% or more, while teams with no prior RFP software typically see improvements of 80% or more.
Comprehensive due diligence questionnaires typically cover several key categories:
Questions about ownership structure, board composition, and corporate policies. Financial services DDQs particularly emphasize governance given regulatory requirements.
Example questions:
- Provide organizational chart showing ownership structure
- Describe board composition and meeting frequency
- List all jurisdictions where entity is registered to conduct business
Audited financials, capital adequacy, and liquidity metrics. For private equity and venture capital, this section often constitutes a significant portion of total questions.
Specific data requested:
- Three years of audited financial statements
- Current and projected runway (for growth-stage companies)
- Description of material contingent liabilities
- Details of any bankruptcy proceedings in the past 7 years
Verification of licenses, registrations, and adherence to industry-specific regulations. This is particularly intensive for financial services (SEC, FINRA), healthcare (HIPAA), and government contractors (FARs).
Technical and administrative controls for protecting sensitive information. Cybersecurity sections now contain extensive questions in financial services DDQs.
Common requirements:
- SOC 2 Type II report (issued within last 12 months)
- Description of encryption methods for data at rest and in transit
- Incident response plan and history of security incidents
- Third-party penetration testing results
Organizations with current cybersecurity documentation respond to DDQs significantly faster than those compiling information ad-hoc.
Business continuity planning, disaster recovery capabilities, and key person dependencies. These questions assess organizational resilience.
Organizations that maintain a current Business Continuity Plan document respond to operational risk sections faster than those compiling information ad-hoc. Arphie maintains a comprehensive Business Continuity Plan that includes work site recovery, application service event recovery, and business impact analysis, with the plan tested annually.
How the organization manages its own supply chain risks. This creates recursive due diligence—your DDQ respondent likely issued similar questionnaires to their vendors.
Questions typically cover:
Environmental, Social, and Governance considerations have become increasingly important in institutional investor DDQs in recent years.
Emerging focus areas:
- Carbon footprint and climate risk assessment
- Diversity, equity, and inclusion metrics
- Whistleblower policies and protections
- Supply chain labor practices
Organizations handling DDQs effectively implement several key strategies:
The problem: Information lives in multiple systems (shared drives, wikis, Slack, individual inboxes, compliance management tools).
The impact: Teams waste significant DDQ response time locating current information, not actually crafting responses.
The solution: Centralized, tagged knowledge repositories where content is maintained by the system of record owner (Finance owns financial statements, InfoSec owns SOC 2 reports, etc.) and versioned properly. Arphie provides live connections to Google Drive, SharePoint, Confluence, Seismic, Highspot, URLs, and more.
The problem: Unclear who authored each response, who reviewed it, and what source material supports it.
The impact: Legal and compliance teams can't confidently approve responses. Organizations may inadvertently contradict themselves across different DDQ responses.
The solution: Metadata capture for every response showing author, reviewer, approval date, and source documents.
The problem: Organizations treat DDQ responses as "set and forget" rather than living documents requiring regular updates.
The impact: Outdated responses create compliance risk and slow deal velocity when recipients question stale information.
The solution: Scheduled reviews tied to underlying documentation updates. When your SOC 2 report is refreshed, trigger a review of all responses referencing it.
DDQ requirements vary significantly by industry:
Volume: Financial services firms handle significant DDQ volume annually.
Focus areas: Regulatory compliance (SEC, FINRA), audited financials, investment process, conflicts of interest, valuation methodology.
Unique requirement: Many institutional investors require annual DDQ updates even for existing relationships, not just new investments.
Focus areas: HIPAA compliance, clinical quality metrics, FDA regulatory status, patient safety protocols, medical malpractice history.
Unique requirement: Detailed credentialing information for key clinical personnel, including license verification and adverse action history.
Emerging trend: Digital health DDQs increasingly include questions about algorithm bias, clinical validation of AI/ML tools, and software-as-medical-device regulatory pathways.
Focus areas: Information security, data privacy, service availability (SLA history), business continuity, customer data handling, subprocessors.
Unique requirement: Technical architecture documentation, API security, and increasingly, AI/ML model governance for products incorporating artificial intelligence.
Time-saver: Maintaining current SOC 2 Type II, ISO 27001, and penetration test reports eliminates redundant questions in typical tech vendor DDQs.
Focus areas: Fund performance metrics, carried interest calculations, LP composition, investment committee processes, key person provisions, political contributions.
Unique requirement: Extensive background checks on investment team members, often including personal financial disclosures.
Volume pattern: Cyclical—highest during fundraising periods (6-18 month windows every 3-4 years), minimal between funds.
AI-native approaches deliver measurable value in specific DDQ tasks:
Use case: Auto-drafting responses by matching DDQ questions to your knowledge base content using semantic similarity (not just keyword matching).
Value: Reduces initial drafting time significantly for standard questions. Subject matter experts focus on review and customization rather than writing from scratch. Arphie's AI combines Q&A Library answers with AI-generated first drafts from connected resources.
What works: Questions with stable, factual answers (company address, ownership structure, standard policies).
What doesn't: Novel questions requiring new analysis, or nuanced questions where context significantly changes the appropriate response.
Use case: Intelligent routing of questions to appropriate subject matter experts, deadline tracking, approval workflows, version control.
Value: Eliminates the project management overhead of DDQ responses—the messages, email threads, and status meetings that consume substantial effort.
Implementation tip: Integration with existing systems of record (e.g., pulling SOC 2 reports from your GRC platform) is more valuable than standalone workflow tools.
Use case: Extracting questions from PDFs or Excel, reformatting responses, generating output in requested format.
Value: Saves time per DDQ—meaningful at volume but not transformative.
Watch out for: Complex tables, embedded legal documents, and custom formatting requirements often require human review regardless of automation.
Common mistakes organizations make in DDQ responses:
The mistake: Reusing a response from a previous DDQ without confirming it actually answers the current question.
Why it happens: Similar-sounding questions can have meaningfully different scopes or focuses.
Real example: Question A: "Describe your incident response plan." Question B: "Describe a recent security incident and how you responded." Copy-pasting your incident response plan document doesn't answer Question B.
Prevention: Always read the question and your proposed response together before submitting.
The mistake: Responses like "We take security very seriously and implement industry-leading controls."
Why it matters: Due diligence professionals are trained to flag vague responses as potential red flags requiring follow-up.
Better approach: Specific, verifiable statements. "We maintain SOC 2 Type II certification (report dated [DATE]), conduct quarterly penetration tests by [VENDOR], and enforce MFA for all system access."
The mistake: Providing contradictory information in different sections of the same DDQ (or across different DDQs to the same recipient).
Why it happens: Different subject matter experts draft responses without visibility into other sections.
Real example: Security section states "all data encrypted at rest using AES-256" while infrastructure section describes older systems using different encryption standards.
Prevention: Cross-functional review before submission, and centralized response management to flag contradictions.
The mistake: Leaving questions blank or providing unclear responses when a question doesn't apply to your organization.
Why it matters: Recipients assume blank responses mean you skipped the question, not that it's inapplicable.
Best practice: Explicitly state "Not applicable—[brief explanation]." Example: "Not applicable—we do not process credit card data and therefore are not subject to PCI-DSS requirements."
Organizations that handle DDQs efficiently treat it as a program, not a series of one-off fire drills. Here's the infrastructure that makes a difference:
DDQs require input from Finance, Legal, Compliance, InfoSec, Operations, and often Product or Clinical teams. Without executive sponsorship, these teams treat DDQs as low priority.
Recommendation: Assign a DRI (Directly Responsible Individual) for DDQ coordination—often lives in Finance, Legal, or Revenue Operations depending on DDQ volume and drivers.
Success metric: Average response turnaround time and percentage of responses requiring minimal revision.
Track which questions are asked most frequently, which generate follow-ups, and where you spend the most time. This data informs knowledge base priorities.
Questions to consider tracking:
Forward-thinking organizations are shifting from point-in-time DDQs to continuous monitoring relationships. Rather than comprehensive questionnaires every 1-3 years, they receive automated updates when material information changes.
How it works: After the initial DDQ, organizations share access to:
Benefit: Reduces DDQ burden while providing more current information than annual questionnaires.
This approach requires robust content management and notification systems—the same infrastructure that makes traditional DDQ response efficient.
Due diligence questionnaires serve as the foundation for risk-informed business relationships. Organizations that treat DDQ response as a strategic capability—not administrative burden—complete questionnaires faster, provide more consistent and defensible information, and close deals more efficiently.
The key is building maintainable infrastructure: centralized knowledge, clear ownership, and appropriate automation for high-volume, standardized questions. This lets your experts focus on what actually requires human judgment: novel questions, nuanced scenarios, and relationship building with the due diligence professionals evaluating your organization.

DDQs focus on risk assessment and compliance verification for evaluating business relationships, while RFPs are procurement-focused documents comparing vendor capabilities and pricing for specific projects. Security questionnaires drill deep into cybersecurity controls with 200+ technical questions about encryption and access controls. DDQs require cross-functional input from finance, legal, compliance, and operations teams, making them broader in scope than security questionnaires but more risk-focused than RFPs.
DDQ completion time varies based on complexity and preparation level, but organizations using AI-native automation see 60-80% speed improvements compared to manual processes. Teams with mature DDQ programs and centralized knowledge bases can reduce response times from weeks to days. One specific example shows InfoSec review time shrinking from a 3-week queue to 1-day turnarounds with automation, directly impacting deal velocity and partnership closure rates.
Comprehensive DDQs typically cover seven key areas: corporate structure and governance, financial health and stability, regulatory compliance and legal standing, cybersecurity and data protection, operational risk management, third-party vendor management, and ESG (environmental, social, governance) standards. Financial services DDQs particularly emphasize governance and regulatory compliance, while technology vendor DDQs focus heavily on information security, with requirements like SOC 2 Type II reports, penetration testing results, and data encryption methods.
Essential documents include three years of audited financial statements, current SOC 2 Type II or ISO 27001 reports (issued within the last 12 months), organizational charts showing ownership structure, business continuity and disaster recovery plans, cybersecurity policies and incident response procedures, and regulatory licenses or certifications. Organizations that maintain current versions of these documents respond significantly faster than those compiling information ad-hoc, as they can directly attach or reference existing materials rather than creating responses from scratch.
The most critical mistakes to avoid are copy-pasting responses without verifying they answer the specific question asked, providing vague marketing language instead of specific verifiable statements, creating inconsistent responses across different sections, and leaving questions blank instead of clearly marking them 'Not Applicable' with brief explanations. Always include specific details like dates, vendor names, and certification numbers rather than generic statements. Implement cross-functional review before submission to catch contradictions between sections drafted by different teams.
Faster DDQ responses directly accelerate deal velocity and partnership closure rates, providing competitive advantage in time-sensitive business development scenarios. Organizations that reduce DDQ turnaround times can close strategic partnerships weeks faster than competitors. The response speed signals operational maturity to potential partners and investors, as efficient DDQ handling demonstrates well-organized compliance, security, and governance programs that are essential for sustainable business relationships.
