Struggling to measure and improve AI performance

What the research shows

Best practices fall into four categories: content (comprehensive knowledge base, regular updates, industry-specific terminology), configuration (clear escalation rules, proper routing, priority flags), monitoring (track accuracy, review conversations, identify gaps), and optimization (learn from corrections, expand automation gradually, measure ROI). The key is starting simple, measuring results, and iterating based on data. Most companies see best results when they automate 70% of inquiries and escalate 30% to humans.

What to look for

Start with Routine Inquiries

Automate high-volume, routine inquiries first (order status, returns, FAQs). These have clear answers and high automation success rates (80-90%).

Maintain Comprehensive Knowledge Base

Keep your knowledge base updated with latest products, policies, and FAQs. AI accuracy depends on quality content — garbage in, garbage out.

Set Clear Escalation Rules

Define when AI should escalate: complex issues, customer requests, low confidence scores. Clear rules ensure customers get help when needed.

Monitor & Iterate Continuously

Review AI conversations weekly, identify knowledge gaps, correct errors, and expand automation gradually based on performance data.

What this means in practice

Companies following AI support best practices see 70%+ ticket deflection, 90%+ customer satisfaction, and 40-60% cost savings. ROI improves over time as AI learns and automation expands.
