Too Much Control or Too Little: Why AI Agents Fail in Practice

AI agents rarely fail because of the technology. They fail because of governance gaps that only surface after something goes wrong in production.

Too Much Control or Too Little: Why AI Agents Fail in Practice

AI agents are increasingly moving out of pilot projects and into production. They can search documents, draft emails, update records, trigger workflows, and interact with customers. That makes them useful, but it also makes governance critical.

Governance means setting clear rules about which data an AI agent can access and which actions it is permitted to take.

Gartner, the business and technology research firm, predicts that by 2027, 40 percent of organizations will downgrade or decommission autonomous AI agents because governance gaps are discovered only after incidents in production.

The warning is specific: AI agent projects fail when companies treat governance as all-or-nothing. Some agents are restricted so heavily they barely function. Others are given too much access too quickly. Gartner notes that governance should vary based on the agent’s level of autonomy, scope of access, and the tasks it is permitted to perform.

Companies should define the appropriate level of governance for different agents when being implemented, not after deployment.

What Gartner Recommends

Gartner recommends proportional governance. Put simply: the level of control should match the level of autonomy.

A read-only agent that summarizes documents does not require the same controls as an agent that can modify ERP data, send emails to customers, or trigger actions across systems. The more an agent can do independently and the more systems it can access, the stricter the controls need to be.

Gartner divides AI agents into four autonomy levels.

Level 1: Observe

At this level, the agent has read access only. It can retrieve defined information and produce an output, but cannot modify systems, send messages, or trigger actions.

Examples include document summarization, internal search, contract review, and knowledge retrieval.

Key controls are access restrictions, authentication, logging, and output review. This is typically the safest starting point.

Level 2: Advise

At this level, the agent produces recommendations or drafts. It still has read access but no write access to business systems.

Examples include email drafts, quote generation, report drafts, and decision support.

A person reviews the output and decides what happens next. Key controls are review steps, quality checks, and clear accountability for the final decision.

Level 3: Act with Approval

At this level, the agent can prepare an action and execute it only after human approval.

Examples include updating CRM records, creating ERP entries, sending prepared customer emails, and processing tickets.

This requires stricter controls: approval workflows, audit trails, security testing, and rollback options. The approval step must be meaningful and cannot be automatic.

Level 4: Act Autonomously

At this level, the agent can execute actions independently within defined boundaries.

This is the highest-risk category, as the agent acts without human approval.

These agents require continuous monitoring, defined safety boundaries, exception handling, rollback mechanisms, and clear accountability. For most mid-sized companies, this should not be the starting point.

Our Recommendations for Small and Mid-Sized Businesses

brainbot’s view is that most mid-sized companies should not start with fully autonomous agents.

The safer starting point is typically Level 1 or Level 2: agents that can read, summarize, research, draft, and prepare work, but cannot independently modify business systems or communicate externally.

This still creates real value. An agent can prepare a quote without sending it. It can summarize a customer file without changing it. It can review an invoice without posting it. It can draft a support response without contacting the customer.

Before moving to higher-autonomy agents, companies should define access rights, approval workflows, logging, rollback options, and accountability for the final outcome.

The goal is not to block AI agents. The goal is to give them the right level of autonomy for the process they support.
