AI automation is easiest to discuss when the input, proposed output, and next action are explicit. Consider a document workflow: staff receives a supplier document, checks key fields, and enters an approved record. An AI feature could suggest those fields and highlight the source passages for review.
This is an illustrative design scenario. It does not imply that extraction is always accurate or that a particular business has achieved a measured saving. The point is to separate the model’s suggestion from the business decision to accept it.
Write the task boundary first. Which document types are supported? Which fields are required? What should happen with an unfamiliar format or an unreadable scan? A narrow first phase makes it possible to compare useful output with unacceptable output and to decide what the system should do next.
Keep authority in the application
The model may propose a classification or a set of values. Ordinary application code should check permitted actions, required fields, types, and business rules before accepting them. A model response is not permission to view a record or change one.
For the document example, staff might see the proposed date, amount, and reference beside the source. The application can flag a missing reference or an amount that fails a deterministic rule. The reviewer then corrects the proposal or rejects it. Approval should create the final record through the same controlled business operation used for ordinary entry.
Treat imported documents and retrieved text as data, even when they contain instructions. OWASP’s guidance on LLM applications identifies prompt injection and excessive agency among the risks to consider. Limit available actions and data to the task, and enforce those limits outside the model. [8]
Begin with a read-only or proposal-only capability when that is enough to evaluate the idea. If later phases include consequential actions, define their approval requirements explicitly. The same person’s ability to read a document does not automatically mean they may approve a transaction based on it.
Make uncertainty visible in the interface
Show the information a reviewer needs to check the result. Keep the original document accessible through the user’s authorized view, identify missing fields, and distinguish a suggested value from an approved value. Do not hide ambiguity behind a polished sentence that appears certain.
Avoid treating a model’s own confidence wording as proof. A useful review process compares the output with the source and business rules. When evidence is missing, provide an ordinary “needs review” state and a clear way to complete the task manually.
Decide how corrections are recorded. Staff may need to know what was suggested, what changed, and who approved the final entry. Keep only the operational history the business needs, with an agreed retention policy and access controls. Do not log every source document by default simply because debugging is easier that way.
Build the fallback before increasing automation
List failure states: a request times out, the provider is unavailable, output is malformed, a document is unsupported, or the proposed data fails validation. Each should lead to a defined application state. A model failure should not make the original document disappear or leave the user unsure whether anything was saved.
Decide which failures may be retried and which need review. Give repeated actions a controlled identity so a retry cannot accidentally create a second business record. Show staff whether work is pending, failed, or complete. Provide an escalation path when an integration remains unavailable.
Plan for the workflow without AI. Manual entry or an existing approved process can remain a usable fallback. That also gives the team a comparison point when evaluating whether the new feature is helpful enough to keep.
Evaluate representative work, then release gradually
Use a set of ordinary, difficult, and unsupported examples with known expected behavior. Include missing values and misleading text, and test the permissions and fallback states alongside output quality. Agree on which errors are tolerable and which must prevent an automatic next step.
OpenAI’s evaluation guidance describes a cycle of defining evaluation criteria, running evaluations, and improving the application. Apply that discipline to the whole business task. A change to a prompt, model, or retrieval source should trigger a review of representative examples, rather than relying on the original demonstration. [9]
Release a small reviewed workflow first. Collect corrections, latency, failure rates, and staff feedback through an agreed reporting process. Compare the cost and effort with the existing method. Increase automation only where the observed behavior and business consequences justify it.
Full Blown can connect AI features to existing web applications, databases, and document processes. Bring a repetitive task and examples of acceptable and unacceptable results. The first useful deliverable may be a bounded prototype with review and recovery already built in.
