AI assistant, agent or workflow rule: what does your process need?

Start with the task, not the label

An employee needs an answer from a travel policy. A finance team needs details from a receipt. A service lead needs an approved task to reach the right system. These are all possible automation conversations, but they do not call for the same design.

Before discussing an AI model or an agent platform, describe the work in ordinary language. What information is supplied? What should be produced? Who can say whether the result is correct? Which action, if any, is allowed to happen next?

Those questions make the choice between a rule, an assistant and an agent more practical.

Use a rule when the condition is clear

A workflow rule follows an agreed condition. If a required field is missing, return the submission. If the request belongs to a category, route it to the responsible team. If an approval is recorded, make the agreed next task available.

The design work lies in defining the conditions and exceptions correctly. A changing business rule needs an owner and a review process. A connection to another application needs validation and a response when the exchange fails. Predictable logic still requires careful implementation.

Rules can provide a useful foundation before any AI is introduced. They establish the record, the responsible person and the point at which further interpretation is needed.

Use an assistant to prepare information for a person

An AI assistant may be useful when the task involves varied documents, a knowledge question or a draft based on supplied records. It could suggest receipt fields, retrieve a relevant policy passage or organise reviewed observations into a report outline.

The review screen matters. A suggested value should appear beside the source. A policy answer should show the passage it relies on. A draft should make it possible to check the underlying evidence. A fluent response is not enough to establish that it is correct.

Decide how missing information will be handled. When the source does not answer the question, an assistant should be able to stop and make that gap visible. Guessing can create more work for the reviewer than an incomplete answer.

Use an agent only when coordinated action is useful

An agent can be designed to carry out a sequence through approved tools. For example, it might prepare a task, ask for approval and then update an agreed record. That introduces a different responsibility from preparing text for someone to read.

Specify the tools it may use, the records it may access and the actions that need approval. Define when it must stop, who handles a failed update and how its activity will be reviewed. An agent should not gain wider permissions simply because a pilot has produced a convincing demonstration.

Test the full working process

A useful pilot includes representative records, ambiguous inputs and cases where the proposed action should not proceed. Check the result and the effort required to supervise it. A document task may need field-level accuracy checks. A coordination task may need a review of assignments, failed updates and duplicate actions.

The business outcome remains the final test. Has the correct request reached the right team? Has the approved information been recorded? Can someone understand what happened without reconstructing the process from messages?

A gradual route into AI

An organisation can begin with rules, add an assistant to a preparation step and explore a supervised agent later if coordination is still a bottleneck. It does not need to adopt every approach at once.

Arukus is beginning work on AI and process automation through focused discovery and pilot opportunities. The starting point is a defined business task, followed by a scoped assessment of data, integrations, review needs and operating costs.
