All courses / Landscape / Module 3 / Chapter 14
Learning objectives
After the lesson the participant can:
- Map the fields of the landscape model to the records that fill them.
- Assess the reversibility tier and the reach class of a unit using the chapter's rules.
- Find the seat of a unit by asking the chapter's three questions and translate the role into a tier.
- Draw unknown fields as absences or as the worst defensible case, and list the resulting gaps.
Key concepts
- A join of records
- A landscape is a join of records that already exist: the AI inventory, the mandate, the delegation register, the contracts, the proxy logs and the decision records. The places where the join fails are the first things the picture has to say.
- Assess the action, not the breach
- Reversibility is assessed on the action the unit takes or shapes, at its hardest-to-reverse class. What a compromised version could do belongs in the threat register. A Level 0 Advisory unit can sit at R3 because of the outcome its suggestion shapes.
- Three questions for the seat
- Who may raise or lower its autonomy level? Who may stop it today without asking anyone? Who answers for it? Where the answers differ, the seat carries the holder of the first. The seat names a tier, not a competence.
- Worst defensible case
- The convention for mode, level, reversibility and reach, which have no unknown value. Where nobody decided the level, draw the unit at the level its permissions allow and write level not decided in the notes, so the mark is challenged.
- Timeline
- The unit's top-level fields give its state at the start of the period; change is a list of dated entries that carry only the fields that changed. The renderer applies the entries up to the date it is asked for.
Interactive exercises
Do them here and get feedback at once. Choose a card and then where it belongs, or drag it.
Interactive exercise 1 · Match
From record to model field
Pair each field of the landscape model, and the units nobody registered, with the record that supplies it, as the chapter gives it.
Interactive exercise 2 · Put in order
A first landscape in six steps
Put the architect's six steps for populating a first landscape model in the order the chapter gives them.
Teaching plan
| 10 min | Opening: the Friday afternoon of Nordvik Region's AI architect with three documents open, and the two marks that were on none of them. |
| 25 min | Lecture: the four kinds of record, the table from record to model field, the rules for reversibility and reach, the three questions for the seat, and the stop path as the field that migrates to evidence. |
| 15 min | Worked example: the teacher reads the rostering system's entry in Nordvik Region's model from the top, then its two timeline entries, and shows how each line appears in the mark. |
| 55 min | Exercise: participants populate a first landscape for their own organisation from the records they have, draw it by hand and list the gaps. |
| 15 min | Closing: each participant reads out the first three lines of their list of gaps; the teacher contrasts Nordvik Region's afternoon by hand with Hansa Mutual's pipeline. |
Discussion
- Nobody curates the proxy logs, which is why they find what the other records missed. Which record in your organisation would show the AI uses nobody registered?
- The risk class is the one field the notation refuses to draw; the model keeps it in the description. What would be lost if high-risk were drawn as a colour or a border?
- Hansa Mutual's pipeline means a unit cannot be forgotten, yet it draws what the records say and nothing else. How would you check by hand whether the page is the whole landscape?
Written exercise
Exercise · 55 minutes
A first landscape from what you have
Follow the architect's six steps for your own organisation, or for Nordvik Region if you have no records to hand. Make one unit per inventory entry, naming the use and not the product. Add a unit with no seat for each AI service nobody registered and one Mode 0 unit for each family of features a vendor switched on. For each unit, write the level per class of action, the hardest action and what undoing it would take, the reach in people, the seat and the evidence. For every field you cannot fill, use the unknown value or the worst defensible case with a note. Draw the V1 by hand, then list every absent seat, every absent diamond at Level 3 and above, every dashed baseline at R3 and every not decided.
Deliverable: A hand-drawn V1 of at least five units with a legend, a table of the units' fields with their source records, and the list of gaps.
Self-test
Choose an answer to see whether it is right, or open the answer below each question.
Nordvik Region's benefits-triage system only ranks a queue while caseworkers decide every case. Why does its mark sit at R3 Hard to reverse?
Show the answer
A. Because the queue it ranks sets how long an applicant waits, and the row follows the outcome it shapes
Reversibility is assessed on the action the AI takes or shapes. A Level 0 Advisory unit does not act, but its row is set by the outcome its suggestion shapes: a benefit application pushed down a queue for a month takes weeks and a process to undo.Nobody has decided the autonomy level of a unit. According to the chapter, how is it drawn?
Show the answer
D. At the level its permissions allow, with level not decided written in the notes
A level nobody set is, in effect, whatever the permissions permit. The worst defensible case is drawn and noted as such so that the mark is challenged rather than accepted. A unit is never left out because its fields are unknown.When is the baseline for a unit's stop path drawn solid, according to the chapter?
Show the answer
C. When the stop has been run in a drill and logged
The landscape records the stop path under evidence by whether it has been exercised. A stop run in a drill and logged is evidence and the baseline is solid; a stop that exists as a paragraph in the mandate is a declaration and the baseline is dashed.
