The meaningful difference is whether the agent actually changes the workflow. An agent that simply summarizes a CRM record or drafts a reply is useful, but it’s still another interface on top of the existing SaaS. The bigger shift happens when it can take actions across the system and complete a task. That’s also where the complexity increases; permissions, integrations, monitoring, failure handling, and human escalation suddenly matter. Recent surveys suggest production adoption is growing, but quality and integration remain major barriers.
