Key Takeaways

Why Some AI Deployments Fail

Not every AI deployment delivers ROI. Common failure modes include:

• No clear use case — Deploying AI without identifying specific tasks
• Underestimating setup costs — Integration, training, and change management
• Choosing the wrong tool — One-size-fits-all doesn’t work in AI
• Lack of measurement — Can’t improve what you don’t measure
• Ignoring change management — User adoption is the #1 predictor of success
