A language model is able to perform such tasks as answering questions, summarizing documents, content generation, and understanding natural-language instructions. However, all these abilities alone do not necessarily help in improving the business process.

Imagine an employee asking an AI assistant about which customers’ invoices are overdue. A language model would not be able to give the employee a valid answer because it would lack the ability to access the company’s recent financial data. Even if the model recognized the overdue invoices, it would not be able to update the accounting database, inform the account manager, or take the following step.

This is when AI development goes further than just prompt and conversation. Developers integrate the language model into the company’s data and systems, thus creating an AI system capable of doing work rather than generating texts.

The workflow comes before the model

The foundation for any AI application starts with understanding the business process.

Prior to incorporating an LLM into it, developers should understand how the process is performed at the moment. Developers consider where the required information is located, which people are able to use it, what approvals are needed, and how to act if some problems occur.

Thus, the automation of the invoice review process means more than just sending the model an invoice to analyze. The system may have to retrieve the supplier data, match it to the purchase order, detect discrepancies between the amounts, and verify the amount of the approved limit before transferring the invoice to the finance department.

Business data gives the model useful context

An LLM learns on general information, while business questions rely on private and regularly changing information.

For example, a sales assistant will need customer information from the CRM. Maintenance assistants might need records about devices from asset management systems. HR assistants will need policy documents that have been approved as well as employee access rights.

Programmers can easily link all these resources via APIs, databases, search systems, or any integration platform. The system will look for the required information and send it to the model as context when receiving the user’s question.

In this way, the model will be able to make its decision using up-to-date company information. Nevertheless, the quality of the answer will always depend on the quality of the initial information. Outdated documents, duplicates, and ownership can lead to incorrect answers even in case of proper model functioning.

APIs turn conversations into actions

However, information access is just one step in workflow integration. There are many business procedures that will necessitate some action from the system.

For example, a customer might be requesting a change of the delivery address for their order. The language model can understand the request, but it would still need to be connected to the API to check the order, verify the new address, update the order management system, and document the change.

The developers will define what tools the model can use and under what conditions. The model will choose the appropriate tool, but the application will validate the request and control the execution of the tool.

AI agents can coordinate several steps

Some of the workflows require multiple systems and decision points to be made. In such situations, the AI agent can serve as a mediator in arranging the order of the process.

For instance, the user may request an internal assistant to generate a weekly sales report for him. This system would gather the required sales data, compare it to the previous week’s data, find any deviations from the norm, generate a summary, and send it to the designated location.

The AI agent does not substitute the applications used in the workflow. Rather, it serves as a mediation layer between the user and applications.

The development team has to specify what kinds of actions can be performed, their order, and what kind of information has to be logged. Otherwise, an AI agent may bring unpredictability into a well-organized workflow.

Permissions protect business systems

The fact that the AI assistant can get the information is no reason for giving it out to the employee.

A properly integrated LLM uses the exact access principles as the systems it works with. The application verifies the credentials and permissions of the person using it before retrieving information or executing an action.

This is particularly critical if the system operates financial data, employee data, customer data, medical documents, and confidential business files.

In addition to that, developers might want to control what actions the model is capable of executing. Reading the order status is done automatically, while updating the payment information or approving a big refund may need additional verification.

Human approval remains part of automation

Linking the LLM to the process does not have to involve excluding humans from every single decision-making activity.

Low-risk and mundane decisions can usually be done by automation. The system could classify the request, generate a draft, find the information that is pre-approved, or just update some routine records. The important decisions may still need to be made by humans.

For instance, an AI assistant may analyse a request by a supplier and provide a recommendation. It will be then reviewed by a purchasing manager who will make the final decision based on that evidence.

Monitoring continues after deployment

AI process requires constant monitoring due to changing company data, users’ behavior, software integrations, and rules of business.

It is not only about the quality of the text that was produced. It is also about checking if the right data was accessed, if the action was successfully performed, how frequently users needed any human intervention, and where the process was broken.

Integration failure is as harmful as wrong answer since the model might fully comprehend the query but still fail to perform due to unavailability of CRM or missing information from API.

Such monitoring will allow fixing these issues and enhancing the process of work.

Good development starts with a practical goal

When hiring AI engineers, companies should start from a particular work-related issue, not a generic idea to use AI technology.

The development group must know about the current process flow, integration needs, security conditions, points of approval, and the expected result of the work.

Among the possible metrics are task completion percentage, processing speed, correction ratio, quality of escalations, and manual activities elimination. These are the signs that AI does something for the process, not for showing the skills.

The LLM becomes part of the business process

Value of LLM lies not only in its capability of generating natural outputs but rather in the link it creates between language and business systems.

Enterprise data provides necessary context for the model. The use of APIs enables it to help with performing actions. Permissions and approvals provide necessary control over them. The process is monitored to stay dependable when changing business needs arise.

Successful implementation does not entail making AI perform every task. Instead, it utilizes language model in places where language understanding and reasoning is useful and lets business rules, enterprise systems, and humans handle areas where consistency and responsibility is more important.
