Framing the Business Problem with Cynefin Domains

Start with the kind of problem

Before a model is chosen, the course asks what kind of situation the business faces. The Cynefin framework sorts problems by how well cause and effect can be known, and the course pairs each kind with a different order of work.

The practical value is that the order tells you what the first release of a GenAI system should do.

Four scenarios from the lecture

Routing basic customer inquiries is clear: sense the message, sort it into a known category, respond. Debugging a large codebase is complicated: gather the report, analyse with a model's help, then let engineers fix and test.

Building a personalised learning platform is complex: probe with varied content and prototypes, sense what works, then adapt.

Countering a disinformation cascade during a health crisis is chaotic: act immediately by deploying monitoring, then sense and respond.

Why the order matters

Using the clear-domain routine on a crisis wastes the one resource a crisis lacks, which is time; using the chaotic routine on a routine process throws away the benefit of known categories.

The optional quiz and the exam review both test these pairings, including creative marketing as complex and a deepfake public-relations crisis as chaotic.

From domain to measurement

The lecture's next question, how the system should sense, leads straight to the KPIs covered in Chapter 8.

Where the answers go wrong

Most mistakes swap the two uncertain domains: treating a crisis as an experiment wastes time, and treating an open-ended product as a crisis skips the learning.

Ask whether there is time to study the situation before you ask whether its answer can be known.

It is chaotic: the situation is unfolding faster than it can be studied, and there is no stable pattern to categorise. The sequence is act, sense, respond. The system should be deployed at once to monitor mentions across platforms and flag copies of the video, then analyse spread and sentiment to see where it is moving, then support the response with prepared factual statements and prioritised escalation to the communications team.
Sia tip — In a timed answer, decide the domain by asking first whether there is time to study the situation; if there is not, the sequence must begin with act.
Glossary

Key terms

Clear Domain
A situation with known cause and effect and an obvious right answer, handled by sensing, categorising and responding.
Complicated Domain
A situation whose answer can be found by expert analysis, handled by sensing, analysing and responding.
Complex Domain
A situation whose cause and effect are visible only in hindsight, handled by probing, sensing and responding.
Chaotic Domain
A situation with no stable pattern and no time to study it, handled by acting, sensing and responding.
FAQ

Framing the Business Problem with Cynefin Domains FAQ

Why does the order of sense, probe and act matter so much?

Because it decides what the first version of a system should do. In a routine process the first step is reading and sorting inputs; in an uncertain one it is running cheap experiments; in a crisis it is taking immediate action. A system designed around the wrong first step will be either too slow or too careless for its situation.

Can one business problem move between domains?

Yes. A crisis that has been stabilised may become complex, and a complex problem that has been studied long enough may become complicated or clear. Re-checking the domain as a deployment matures is sensible, because the right sequence and the right metrics change with it.

Which domain fits routing simple customer inquiries, and why?

The clear domain. Inquiries arrive through known channels and fall into predefined categories, so the system can sense the message, sort it into a category and respond with an automated reply, a routing decision or an escalation to a person. Nothing needs to be discovered before acting.

Study strategy

Exam move

Learn the four domains as a table of name, sequence and one course scenario, then invent one scenario of your own for each. The two most often swapped are complex and chaotic, so practise telling them apart by whether there is time to experiment.
