Personal · from the framework reference, not the book
A family holiday
The framework master reference used a seven-day family holiday — a couple in their late forties, a daughter of eighteen, a son of twelve, a fixed budget — as its universal example. It did not make it into the narrative. It belongs here, because it is the case a parent will recognise first.
In brief
This case is laid out against the eight steps of the framework. Jump to Step 1 to see how the end state was defined, or to Step 8 to see what integration caught.
Define the End State
Alone, before opening any app: what should this week feel like for four people who want different things? Not "seven days in Kerala" but "the eighteen-year-old comes back having had one experience that was hers, the twelve-year-old is not bored for more than an hour at a stretch, the two of us get two unhurried evenings, and nobody is doing arithmetic at dinner."
Map the Flow
Your own list first: dates, budget, travel, stays, what each person wants, the one non-negotiable each has. Then AI reviews it: what have you not thought of? Typically — buffer days, the temple closed on the day you planned, a late-arriving flight that eats the first evening, meal logistics for a family that argues about food.
Assign Tasks
Deciding what the week is for: human. Generating twenty itinerary options within budget: AI. Choosing among them: human. Checking opening days and distances: AI, verified. Persuading the twelve-year-old: human, unavoidably.
Select the Tool
A conversational model for the plan (iterative, medium context); a tool with live web access for anything factual — timings, prices, closures.
Prepare and Direct
The tool is briefed like a travel agent who has never met the family: ages, preferences, budget, energy levels, what went wrong last time. The success criteria written first: total under budget, no two travel days in a row, one thing per person that is theirs.
Execute
The plan is built. Bookings are made by the humans.
Evaluate
Against the criteria — and the plan fails one: three consecutive days of driving. Iterate.
Integrate and Stress-Test
Small fixes: a shut restaurant, no buffer before the return flight — just fix them. Structural: the budget does not add up once real prices land, and fixing one stay breaks the sequence. Trace to Step 2: reprioritise the whole flow rather than patching the night that overran.
