Turn incoming events into a clearer next step.

A service desk receives a report that a delivery has stopped updating. The tracking feed confirms that no new position has arrived, but that alone does not explain the situation.

The team may need to check the planned journey, recent device messages, carrier updates, customer commitments, and the procedure for handling missing tracking data.

Repeating those checks for every incident takes time. Sending the alert straight to an AI model leaves it without the evidence needed to give a useful answer.

D4 can receive an event, validate its contents, and gather relevant information from connected systems before calling a model.

For the missing delivery update, that context might include the last recorded position, expected reporting interval, delivery window, carrier status, and applicable handling procedure.

An LLM can then be asked to perform a bounded task: summarise the evidence, classify the issue, identify missing information, and suggest a next step. Its response can follow a defined structure so that the surrounding workflow can check and use it.

The result could state that tracking information is stale, that the delivery status remains unconfirmed, and that a carrier check is needed before a customer update is prepared.

• Receive the event: Capture an alert, status change, customer report, or other trigger.
• Gather context: Add relevant records, recent events, service commitments, and approved procedures.
• Apply AI: Produce a concise explanation, proposed classification, and recommended next step grounded in the supplied information.
• Validate the result: Check required fields, permitted values, supporting references, and conditions for human review.
• Route the output: Prepare a service ticket, internal briefing, draft customer update, or structured API response.

A model recommendation does not have to trigger an action directly. The workflow can require approval, limit the actions available, or route uncertain cases to a person.

Deterministic rules can establish facts such as whether a reporting interval has been exceeded. The model can help explain those facts in context and prepare an output suited to its audience.

A service agent might receive an investigation brief with links to the underlying records. A customer communication team might receive a draft update containing only confirmed information. Another application might receive a structured classification and suggested routing.

Missing or conflicting evidence can be surfaced explicitly, giving the recipient a clearer basis for deciding what to do.

The same approach can support delivery exceptions, service interruptions, equipment alerts, and other events that require teams to gather context before responding.

Each workflow can define its own sources, model task, validation rules, and approval requirements. This gives AI a specific role between incoming data and a useful output, with a traceable path from the original event to the proposed response.
