Scenarios

Where AI deployment actually pays off first

We do not tell industry stories. Below, use cases are broken down by what they solve, where they stick, what is delivered and how you would know it worked.

First, what makes a use case worth doing

Inside one company, some use cases go live in two weeks and others never land after a year. The difference is rarely technical difficulty — it is whether four conditions hold at once.

Condition 1

There is a business metric to move

Not "we want to use AI to be more efficient", but "this step takes twelve minutes on average and we want it under four". If the metric cannot be stated, acceptance cannot be defined.

Condition 2

The data can be obtained and is adequate

The data needed exists, can be extracted, and is good enough to support a decision. This is the most common hidden blocker and the first thing we examine during assessment.

Condition 3

Real users will take part

A system is ultimately used by specific people. If they were absent from design, it will most likely sit unused — the most underrated cause of AI project failure.

Condition 4

Being wrong is recoverable

Start with steps where a wrong answer can be caught by a human. Decisions touching money, safety or compliance should begin with assistance rather than replacement.

Six common scenarios

Each gives the typical problem, the real difficulty, the deliverables and how to tell whether it worked. These come from public industry discussion and our own forward deployed engineering practice, with no client detail. What any of it costs, and how we price it, is on the engagements page.

01

Customer service and tickets

Typical problem

Repeat questions consume most of the team, and when a case escalates the context is lost, so the customer explains everything again.

Where it actually sticks

The difficulty is not answer quality. It is two other things: the state of historical ticket data (often incomplete before you start) and the rules for escalating — what must go to a human, and to whom.

Deliverables

  • An assist tool for agents, with citations to source material
  • Escalation rules and context handover
  • An evaluation set built on real tickets, with accuracy reporting

How to measureFirst-contact resolution, average handling time, escalation rate, rate of human correction.

02

Enterprise knowledge search

Typical problem

Knowledge is scattered across documents, wikis, email and chat. New joiners take months to get up to speed and experienced staff answer the same questions repeatedly.

Where it actually sticks

The hardest part is permission isolation: different roles and departments are entitled to different material. Until permissions are right, answer quality is irrelevant. Second is freshness — an out-of-date document is more dangerous than a missing one.

Deliverables

  • Retrieval and question answering with permission filtering
  • A source inventory and a mechanism for marking currency
  • Coverage reporting: what the system cannot answer, and why

How to measureQuestion coverage, answer adoption, human intervention rate, time for a new joiner to become productive.

03

Document and invoice processing

Typical problem

Contracts, orders, invoices and inspection reports are keyed in by hand — slow and error-prone.

Where it actually sticks

Layout inconsistency and exceptions. The same document type arrives in different formats from different suppliers, with handwriting, stamps over text and skewed scans. You need a designed fallback for what cannot be read, not an assumption of perfect accuracy.

Deliverables

  • Structured extraction producing verifiable fields
  • Confidence thresholds and a human review queue
  • Field-level accuracy reporting

How to measureAccuracy per field, share sent for human review, time per document, rework caused by errors.

04

Data questions and analysis

Typical problem

Business staff queue for data requests, and the data team spends its time on repeat extractions.

Where it actually sticks

Not translating natural language into SQL — that is the easy part. The difficulty is consistent definitions. Sales, finance and operations may each define "active customer" differently, and when definitions diverge nobody trusts the number.

Deliverables

  • A natural-language query interface with stated definitions and a traceable query path
  • A metric definition dictionary — consistently under-scoped work
  • A mapping between permissions and data scope

How to measureFall in manual data requests, share of query results adopted, number of definition disputes.

05

Cross-system process automation

Typical problem

One task is entered into three or four systems, with people and email moving data between them.

Where it actually sticks

Exception handling. The happy path is straightforward; what is hard is what happens when a system is briefly unavailable or a record fails validation. Automate without designing the exception paths and you have added work rather than removed it.

Deliverables

  • The automated flow and its exception rules
  • Retry and human take-over mechanisms
  • Runtime monitoring and alerting

How to measureNumber of manual steps, end-to-end time, frequency of exception interrupts.

06

Quality inspection and equipment warning

Typical problem

Defects are found by sampling after the fact, and equipment failures cause unplanned downtime.

Where it actually sticks

These scenarios demand the most from the data foundation: sensor coverage, sampling frequency, labelled historical failures. Where that foundation is missing, no model will produce a result — and we will say so rather than start.

Deliverables

  • Anomaly detection and early warning models
  • Integration with existing ticketing or line systems
  • Threshold tuning and false-positive assessment

How to measureMissed-detection and false-alarm rates, warning lead time, unplanned downtime.

How industries differ

The same scenario category runs into different obstacles in different industries. These are the differences we meet repeatedly.

Manufacturing

Many legacy systems with closed interfaces, and a gap between plant-floor data and IT. Sensible entry points are bounded work such as document processing or inspection support.

Financial services

The highest compliance and audit demands: any automation needs a trail and an explanation. Start with decision support rather than automated decisions, and design audit logging from day one.

Healthcare

High data sensitivity, usually requiring on-premise deployment or operation inside the hospital network. Sensible entry points reduce administrative load: documentation and record structuring.

Public sector

Long procurement cycles, often requiring pre-qualification onto a supplier list. On-site service capability is explicitly assessed, as is ongoing support after delivery.

Retail and consumer

Large data volumes spread across channels, with consistent definitions as the main work. Entry points that show results quickly: support, product content generation, review analysis.

Scenarios we usually advise against

Prediction projects without the data foundation

Without enough historical samples and labels, a predictive model will not produce a usable result. We would rather help you build the data foundation first than build a model that cannot work.

Projects whose goal is to have an AI project

If the reason for starting is to have an AI initiative rather than to move a specific metric, acceptance will be difficult. The goal is worth rewriting as a business indicator first.

Projects that replace a critical decision outright

For decisions involving money, safety or compliance, the sensible role today is assistance and prompting, not unreviewed automatic execution. That is a question of accountability, not technical caution.

Requirements a mature product already covers

For standardised needs, buying a product is cheaper and faster than custom development. We will tell you to buy it, even though that is not our business.

Common questions

Which industries have you worked in?

The industry experience we can discuss publicly sits in manufacturing, financial services, healthcare, the public sector and retail. Confidentiality means we have no named cases we can publish, and we will not dress that up. During assessment you can ask us to walk through comparable situations, the problems we hit and the approaches that proved useless.

Our scenario is not in the six above — can you still help?

That list describes common shapes, not the limits of what we do. The test is the four conditions: a measurable indicator, usable data, participating users, and recoverable mistakes. A new scenario meeting all four is workable.

How long from start to live?

Assessment typically takes one to two weeks; a pilot three to eight, depending on how many existing systems are involved and how usable the data is. Unusable data is the most common cause of delay, which is why we check it during assessment rather than discovering it during development.

Can we start with something small?

That is what we recommend. A fixed-scope pilot narrows the work to the smallest unit that can be validated, and scales only once thresholds are met. Scope is frozen at the start and acceptance criteria are agreed in advance.

Is your scenario on this list?

Describe the specifics. We will judge whether it meets those four conditions — and if the answer is that it should not be done, we will write that down.
