🚨 The Problem: When Their Delay Becomes Your Breach

A single slow vendor (cloud, ISP, SaaS, logistics, creative subcontractor) can cascade into your SLA misses, reopens, and angry stakeholders. Without evidence, escalation, and remedies wired into contracts, you eat the cost—credits, rework, and renewal risk. This playbook makes vendor impact visible, actionable, and recoverable.

🟢 Risk Conditions (Act Early)

Treat these as early-warning signals to engage the vendor before your SLOs wobble:

Upstream case aging above OLA target (e.g., > 24/48h with no status update)
Repeat incidents tied to the same product/service over 14–30 days
Rising reopen rate on categories dependent on this vendor
Vendor maintenance / change windows overlapping your peak periods
Ticket correlation: ≥ 10–15% of your SLA-at-risk tickets reference the vendor

What to do now: assemble evidence, open the escalation track, and enable a workaround path.

🔴 Issue Conditions (Already in Trouble)

Move to containment if any apply:

Your SLA breaches are directly linked to vendor cases (chain of timestamps)
Credits paid or forecasted due to vendor latency
Executive escalation from your customer naming the vendor dependency

What to do now: invoke remedies, communicate impact with proof, and re-route service where possible.

🔎 Common Diagnostics

Fast checks to select the right path:

OLA specificity: Is the vendor OLA clear (targets, clocks, severity, comms cadence)?
Evidence quality: Do you have linked IDs and time-stamped events showing delay impact?
Workaround feasibility: Can you bypass, roll back, or substitute a component temporarily?
Change/maintenance clash: Did vendor changes align with your blackout windows?
Systemic vs isolated: Is this a one-off incident or a trend across regions/customers?

🛠 Action Playbook

1) Evidence & Escalation (Risk Stage)

Create a vendor dossier: affected tickets, timestamps, severity, business impact, screenshots/logs
Open OLA escalation: follow ladder (support → duty manager → TAM → exec) with SLAs for updates
Request ETA & mitigation: interim steps, rollback plan, or workaround acknowledgment
Communicate to customers: send risk notice referencing vendor case ID and your mitigation plan

Expected impact: faster vendor attention; documented causality for remedies.

2) Mitigation & Continuity (Risk → Early Issue)

Implement workaround: switch path, roll back version, degrade gracefully (reduced feature set)
Re-route service: alternate provider, cached content, manual process, or temporary policy change
Prioritize queues: fast-track P1/P2 tied to vendor impact; pause non-urgent intake if contracts allow
Increase update cadence: internal every 2–4h; external daily or per clause

Expected impact: limits SLA damage; maintains trust via visible control.

3) Commercial Remedies (Active Issue)

Invoke contractual remedies: credits/penalties, service extensions, or professional services at vendor expense
Cost recovery: attribute credits and rework cost to vendor per pass-through clauses
Amend OLA/contract: tighter response/restore targets, explicit blackout windows, redundancy obligations
Performance plan: vendor CAP (corrective action plan) with milestones and reporting cadence

Expected impact: recoups losses; reduces repeat risk.

4) Hardening & Alternatives (Post-Mortem)

Vendor scorecard: MTTA/MTTR/OLA compliance, incident rate, maintenance hygiene
Dual-vendor or failover pattern where justified (multi-AZ/region, secondary provider, on-prem fallback)
Change governance: require pre-change notice windows, rollback criteria, and joint testing for critical paths
Runbook library: codify workarounds; add synthetic monitoring for early detection

Expected impact: resilience increases; future vendor issues detected and contained earlier.

📜 Contract & Renewal Implications

Pass-through credits & penalties: ensure your customer credits are recoverable from the vendor
OLA alignment: response/restore times and comms cadence that match your SLA tiers
Change control & blackout windows: notice periods, approval rights, rollback obligations
Right to substitute/dual-source: commercial flexibility when reliability degrades
Evidence requirements: data sharing & logs to prove impact and claim remedies

📈 KPIs to Monitor

Vendor-attributed SLA breaches — target ↓ to 0
Vendor case aging vs OLA — target within agreed clocks
Time to vendor escalation resolution — target ↓ 25–50% vs prior incidents
Reopen rate (vendor-dependent categories) — target baseline or better
Customer SLA compliance — target at/above tier despite vendor incidents

🧠 Why This Playbook Matters

Customers judge your service, not your suppliers. When vendor issues become predictable and managed, you keep control of outcomes and costs. Evidence-led escalation plus clear remedies turns finger-pointing into measured recovery—and protects your renewal story.

✅ Key Takeaways

Prove causality: linked IDs and timestamps convert blame into remedies.
Escalate with structure: follow the OLA ladder and demand ETAs/mitigations.
Keep service moving: workarounds and re-routing protect your SLA.
Recover costs: pass-through credits and amend OLAs to reality.
Build resilience: scorecards, dual-paths, and change governance prevent repeats.
