An internal assistant can answer quickly and still leave a team unsure which answer to trust. The underlying problem may be familiar: two versions of a process, an old price sheet, an undocumented exception or a folder nobody owns. Faster access does not resolve those disagreements.
Before choosing an interface or model, pick one group of users and one set of questions. For example: “Help the service team find the current procedure for preparing a standard visit.” That is a more useful starting point than “Let everyone ask about everything.” The smaller scope lets you inspect the source material and the conditions under which an answer is useful.
Make a source inventory people can maintain
| Field | What to record | Why it matters |
|---|---|---|
| Source | The actual document or authoritative system. | A folder name alone is not enough to identify the answer. |
| Business owner | The role that can resolve a content question. | Someone must decide which version is correct. |
| Audience | Who may see the information. | Searchability must respect the intended access boundary. |
| Effective date | When the information becomes valid and when it should be reviewed. | A recent upload can still contain an old policy. |
| Scope | Products, locations, teams or circumstances covered. | A correct answer in one context can be wrong in another. |
| Exception route | Who handles a missing or unusual case. | The assistant needs a useful way to stop and refer. |
| Retirement rule | How superseded material leaves the active set. | Old instructions should not compete silently with current ones. |
Start with a sample you can review manually. Ask the people doing the work which documents they actually use and which they avoid. A frequently opened file may be convenient rather than authoritative. Record that distinction before importing it into a new system.
Resolve the disagreements before indexing
Take a handful of ordinary questions and have two knowledgeable people answer them independently using the proposed sources. When their answers differ, find out why. The source may be ambiguous, the process may vary by team, or the decision may rely on an exception that was never written down.
Ask the business owner to approve the current wording or document the applicable conditions. Keep unresolved topics outside the first pilot or make the uncertainty explicit. A model should not be the authority that silently chooses between conflicting policies.
- Merge or retire duplicates only through the owner’s normal content process.
- Keep context next to instructions: who, when, where and which product or service.
- Replace unexplained abbreviations when the intended users may not know them.
- Identify the person or queue that handles exceptions.
- Set a review date that matches how quickly the information changes.
Understand what retrieval adds
Retrieval-augmented generation, often called RAG, supplies relevant source content to a language model when it answers. Microsoft’s guidance describes content preparation, retrieval quality and access control as important design concerns. Connecting documents is a starting point; it does not guarantee a correct, current or complete answer. [1]
For a first pilot, require the assistant to identify the source it used and make that source available to the authorized reader. Decide what happens when no adequate source is found. A short response explaining the gap and the next person to ask can be more useful than a confident answer assembled from weak evidence.
Check access at the source and in the answer
Microsoft documents several approaches to document-level access control in Azure AI Search, with availability and implementation details that vary by approach. The essential design question for your own system is whether a particular user is allowed to retrieve each piece of content—not merely whether the assistant itself can read the repository. [2]
Write down a simple access matrix: user group, source set and permitted action. Have the system owner verify it against the actual repository and application configuration. Include users with different roles when evaluating results. A helpful answer must also be an answer that person is entitled to receive.
Give the pilot an operating owner
Name the person responsible for content changes, the person responsible for the application and the person who receives reported answer problems. These may be different people. Agree how a corrected source reaches the assistant and how you verify that retired information is no longer returned.
Leave the preparation phase with a small approved source set, an access matrix, a list of unresolved questions and a maintenance schedule. Then evaluate the assistant against representative questions and exceptions. Track unanswered questions as input to the knowledge process, not just as a model problem.
The valuable work begins before the chat box: making the organization’s knowledge easier to trust, govern and use. That work remains useful whether your next step is a better search page, a workflow application or an AI assistant.
