Approval workflows route AI decisions to human reviewers based on confidence levels, risk thresholds, or policy requirements. They determine which decisions execute automatically and which need human oversight before action. For businesses, this enables confident automation because high-risk decisions get human eyes. Without approval workflows, AI either executes everything automatically or requires review of everything.
Your AI sends a refund to a customer who asked for a receipt.
When you investigate, nobody reviewed it. The confidence was 68%, but it executed anyway.
Automation without approval is just a faster way to make expensive mistakes.
The goal is not to slow things down. It is to know which decisions need human eyes.
HUMAN INTERFACE LAYER - Where AI and human judgment work together.
Approval workflows determine which AI decisions execute automatically and which require human review before action. They are the control layer that lets you automate confidently because you know risky decisions will get human eyes.
The key is not reviewing everything. That defeats the purpose of AI. The key is knowing exactly which decisions are safe to automate and which need oversight. Confidence thresholds, dollar amounts, policy sensitivity, customer tier - these become your routing rules.
A well-designed approval workflow is invisible 90% of the time. It only surfaces when the AI encounters something that genuinely needs human judgment.
Approval workflows solve a universal problem: how do you let things run automatically while maintaining control over what matters? The same pattern appears anywhere decisions have varying levels of risk.
Evaluate decision risk at decision time. Route low-risk decisions to auto-execution. Route high-risk decisions to human review. Learn from outcomes to refine routing rules.
Adjust routing thresholds and see how 8 refund decisions get routed. Watch for errors that slip through versus decisions that get caught by human review.
Route by confidence or value
Set numeric thresholds that determine routing. Decisions above 85% confidence auto-execute. Decisions between 60-85% go to tier-1 review. Decisions below 60% go to senior review. Simple, transparent, easy to adjust.
Route by decision characteristics
Define routing rules based on decision attributes. VIP customers always get human review. Legal-sensitive topics route to compliance. First-time actions for any category need approval. More complex but more precise.
Route based on learned patterns
Use historical data to predict which decisions are likely to need intervention. Learn from human corrections to refine routing. Route decisions that resemble past problems to human review.

How many AI decisions do you need to route per day?
The ops lead investigates an automated refund that caused customer confusion. The AI was only 68% confident, but without an approval workflow, it executed automatically. The workflow now routes low-confidence financial decisions to human review.

Notice how the core pattern remains consistent while the specific details change
Every decision goes to a human queue. The queue becomes overwhelming. Reviewers rush through approvals without really reviewing. You have created the illusion of oversight without actual oversight.
Instead: Start by auto-approving obviously safe decisions. Only route genuinely uncertain or high-risk items. Measure queue depth and reviewer time per item.
A decision routes for approval. The approver is on vacation. The decision sits for three days. The customer has already left. Your approval workflow became a bottleneck.
Instead: Build in SLAs with automatic escalation. If approval is not received in 4 hours, escalate to backup. If still no response, either auto-reject or auto-approve based on risk profile.
Decisions route to humans who approve 99% of them without changes. You are wasting human time on decisions the AI could have handled. Or worse, decisions route that humans reject 80% of - your AI is broken.
Instead: Track approval and rejection rates by routing rule. High approval rates suggest over-routing. High rejection rates suggest your AI needs retraining on that category.
Approval workflows are routing mechanisms that determine which AI decisions execute automatically and which require human review before action. They evaluate decisions against thresholds like confidence scores, dollar amounts, or policy sensitivity. Low-risk decisions proceed automatically while high-risk decisions route to appropriate human reviewers for approval, rejection, or modification.
Implement approval workflows when your AI makes decisions with real consequences where mistakes are costly. This includes financial transactions, customer communications, access permissions, and any action that cannot be easily undone. Start with your highest-risk categories and expand coverage based on observed error rates and business impact.
The most common mistake is routing everything for review, which overwhelms reviewers and creates rubber-stamping. Another mistake is having no timeout or escalation, causing decisions to stall when reviewers are unavailable. Also avoid ignoring routing accuracy metrics. Track approval rates to identify over-routing and rejection rates to identify AI quality issues.
Escalation logic determines WHEN a decision should be routed based on thresholds and rules. Approval workflows handle HOW the routing happens: which queue, which reviewer, what context to include, and what SLAs apply. Escalation decides "this needs review" while approval workflows manage the review process itself.
Start conservatively with lower thresholds that route more decisions to review. Track what percentage of routed decisions get approved without changes. If approval rates exceed 95%, your threshold is too low and you are over-routing. Gradually raise thresholds while monitoring for increases in errors that slip through. The right threshold balances efficiency with acceptable error rates.

All AI decisions execute without human review
Some decisions route to humans, but routing is ad-hoc
Approval workflows exist but may be over- or under-routing
You have learned how to route AI decisions to human reviewers. The natural next step is managing the queue of items waiting for review and capturing the feedback from reviewers.
