3 Mistakes TPRM Teams Keep Making - and How the Best Programs Avoid Them

Third-party risk management (TPRM) teams don’t get credit for effort; they’re measured on outcomes, evidence, and defensibility. If your program still feels slow, noisy, or stressful at audit time, chances are you’re running into one (or more) of these patterns. Use this article to sanity-check your program and identify quick wins.
First, a quick refresher: what “better” looks like in TPRM
- Evidence-first, not questionnaire-first. Start with what vendors already publish (attestations, certifications, policies, assessment responses), then use questionnaires only where gaps remain.
- Signal-driven monitoring. Don’t wait for annual recerts; respond when something meaningful changes.
- Defensible decisions. Clear rubrics, tidy evidence trails, and reports you can hand to stakeholders without a fire drill.
Keep that picture in mind as you read the mistakes below.
Mistake 1: Starting with a questionnaire instead of the best available evidence
What happens
For years, questionnaires have been the default starting point in TPRM. Every new vendor gets a massive spreadsheet—regardless of tier, context, or what they’ve already published elsewhere.
Why it happens
A “one-size-fits-all” approach feels safer and simpler, especially when teams are working with incomplete or outdated vendor profiles. Many programs are also reluctant to scope out controls without explicit justification—so they default to sending everything, every time.
How it shows up
- The same 200–300 questions go to both a niche, low-risk tool and a critical, high-impact provider.
- Weeks of email chasing SOC 2/ISO reports, policies, and SIG/CAIQ responses that vendors already maintain in a trust center.
- Analysts spend cycles reconciling duplicate information instead of analyzing true risk.
Why it hurts
Questionnaires still have their place, but when they’re the first step for every vendor, they create unnecessary drag. Onboarding slows, strategic vendors get frustrated, and teams drown in low-value busywork. Too often you end up asking for answers you already have—or worse, burning precious time on low-risk vendors while the truly high-risk relationships don’t get the focus they deserve.
What to do instead (evidence-first, questionnaire-smart workflow)
- Start with what exists: Pull the vendor’s latest attestations (SOC 2, ISO), policies, pen-test summaries, and industry questionnaires (SIG/CAIQ).
- Map to your controls: See which requirements are already satisfied.
- Close gaps with targeted questionnaires: Only ask additional questions where the evidence is silent or unclear.
- Right-size by tier: Keep a “profile-only” path for low-risk vendors, while reserving scoped questionnaires for higher-impact services.
- Build Vendor Profile Template: Document what data points (data type, volume, system access, criticality etc.) should be required for each Vendor Profile, so you can confidently scope each assessment.
Takeaway
Questionnaires don’t go away—but they get smaller, faster, and more meaningful when you use them as a gap-closing tool instead of a starting point.
Mistake 2: Treating monitoring as a calendar event, not a signal
Why it happens
Programs were built around annual recertification—comfortable on paper, blind to real-time change.
How it shows up
- Quarterly “please reconfirm nothing has changed” emails.
- Expiring certifications discovered during an audit, not before.
- No consistent way to see which vendors changed policies, added sub-processors, or disclosed incidents last week.
Why it hurts
You operate on stale posture, miss early indicators, and spend equal time on vendors that haven’t changed and those that have.
What to do instead (signal-driven monitoring)
Create a signal catalog with action rules by tier. Examples:
- Evidence expiry (≤60 days): auto-request refresh; light review on receipt.
- Policy version change: confirm scope; validate any control deltas.
- New sub-processor: review data type/region; confirm contractual coverage.
- Security incident disclosure: trigger enhanced due diligence; confirm remediation.
- Ownership/hosting change: reevaluate inherent risk and data residency.
Then, route signals to the right owner with SLAs, and log the decision and evidence received so you can show your work later.
Mistake 3: “Audit-ready” in theory, not defensible in practice
Why it happens
Teams optimize for completing assessments, not for proving how decisions were made.
How it shows up
- Evidence scattered across email and shared drives; approvals in chat.
- Risk ratings that shift year-to-year with no visible rationale.
- Findings discussed in meetings but never tracked through to closure.
Why it hurts
During audits, customer reviews, or board reporting, you scramble to reconstruct lineage. “We remember” isn’t an acceptable control.
What to do instead (decision defensibility)
- Codify a rubric: Document tiering (inherent risk × impact) and scoring rules. Apply them consistently.
- Track finding lifecycles: Open → plan → verify → close, with evidence at each step.
- Maintain a controls-to-evidence map: Make it obvious which artifacts support which control expectations.
- Standardize reporting: Keep a lightweight “audit pack” that shows vendor tier, evidence reviewed, residual risk, open findings, and renewal dates—ready to export.
Quick self-assessment checklist
Use this to spot easy improvements in the next 30 days:
- We start with existing evidence and only ask targeted follow-ups
- Our tiering rubric is written down and applied consistently
- We have a signal catalog with clear action rules by vendor tier
- We track evidence expirations and request refreshes proactively
- Findings move through a documented lifecycle with proof at each stage
- We can generate a concise audit-ready report in minutes
Where to go from here
Small shifts—evidence-first intake, signal-driven monitoring, and defensible documentation—deliver outsized gains in speed and confidence. Start by piloting the checklist with a handful of vendors, then scale across your portfolio.
